Overview ¶
Package tdhttp provides some functions to easily test HTTP handlers.
Combined to td package (https://pkg.go.dev/github.com/maxatome/go-testdeep/td) it provides powerful testing features.
TestAPI ¶
The better way to test HTTP APIs using this package.
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/person/42", "Accept", "application/xml"). CmpStatus(http.StatusOK). CmpHeader(td.ContainsKey("X-Custom-Header")). CmpXMLBody(Person{ ID: ta.Anchor(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 26, }) ta.Get("/person/42", "Accept", "application/json"). CmpStatus(http.StatusOK). CmpHeader(td.ContainsKey("X-Custom-Header")). CmpJSONBody(td.JSON(` { "id": $1, "name": "Bob", "age": 26 }`, td.NotZero()))
See the full example below.
Cmp…Response functions ¶
Historically, it was the only way to test HTTP APIs using this package.
ok := tdhttp.CmpJSONResponse(t, tdhttp.Get("/person/42"), myAPI.ServeHTTP, Response{ Status: http.StatusOK, Header: td.ContainsKey("X-Custom-Header"), Body: Person{ ID: 42, Name: "Bob", Age: 26, }, }, "/person/{id} route")
It now uses TestAPI behind the scene. It is better to directly use TestAPI and its methods instead, as it is more flexible and readable.
Example ¶
Output: GET /person/42 - JSON: true GET /person/42 - XML: true GET /person/42 - raw: true POST /person - XML: true → Bob ID=1 POST /person - JSON: true → Alice ID=2 POST /person - raw: true → Britt ID=3 GET XML Alice: true GET JSON Alice: true DELETE Alice: true Alice is not found anymore: true

Functions ¶
func CmpJSONResponse ¶
func CmpJSONResponse(t testing.TB, req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response, args ...interface{}, ) bool
CmpJSONResponse is used to match a JSON response body. The req *http.Request is launched against handler. If expectedResp.Body is non-nil, the response body is json.Unmarshal'ed. The response is then tested against expectedResp.
"args..." are optional and allow to name the test, a t.Log() done before starting any test. If len(args) > 1 and the first item of "args" is a string and contains a '%' rune then fmt.Fprintf is used to compose the name, else "args" are passed to fmt.Fprint.
It returns true if the tests succeed, false otherwise.
ok := tdhttp.CmpJSONResponse(t, tdhttp.Get("/person/42"), myAPI.ServeHTTP, Response{ Status: http.StatusOK, Header: td.ContainsKey("X-Custom-Header"), Body: Person{ ID: 42, Name: "Bob", Age: 26, }, }, "/person/{id} route")
Status, Header and Body fields of Response struct can all be TestDeep operators as it is for Header field here. Otherwise, Status should be an int, Header a http.Header and Body any type encoding/json can Unmarshal into.
If Status and Header are omitted (or nil), they are not tested.
If Body is omitted (or nil), it means the body response has to be empty. If you want to ignore the body response, use td.Ignore() explicitly.
See TestAPI type and its methods for more flexible tests.
func CmpJSONResponseFunc ¶
func CmpJSONResponseFunc(req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response) func(t *testing.T)
CmpJSONResponseFunc returns a function ready to be used with testing.Run, calling CmpJSONResponse behind the scene. As it is intended to be used in conjunction with testing.Run() which names the sub-test, the test name part (args...) is voluntary omitted.
t.Run("Subtest name", tdhttp.CmpJSONResponseFunc( tdhttp.Get("/json"), mux.ServeHTTP, tdhttp.Response{ Status: http.StatusOK, Body: JResp{Comment: "expected comment!"}, }))
See CmpJSONResponse documentation for details.
See TestAPI type and its methods for more flexible tests.
func CmpMarshaledResponse ¶
func CmpMarshaledResponse(t testing.TB, req *http.Request, handler func(w http.ResponseWriter, r *http.Request), unmarshal func([]byte, interface{}) error, expectedResp Response, args ...interface{}, ) bool
CmpMarshaledResponse is the base function used by some others in tdhttp package. The req *http.Request is launched against handler. The response body is unmarshaled using unmarshal. The response is then tested against expectedResp.
"args..." are optional and allow to name the test, a t.Log() done before starting any test. If len(args) > 1 and the first item of "args" is a string and contains a '%' rune then fmt.Fprintf is used to compose the name, else "args" are passed to fmt.Fprint.
It returns true if the tests succeed, false otherwise.
See TestAPI type and its methods for more flexible tests.
func CmpMarshaledResponseFunc ¶
func CmpMarshaledResponseFunc(req *http.Request, handler func(w http.ResponseWriter, r *http.Request), unmarshal func([]byte, interface{}) error, expectedResp Response) func(t *testing.T)
CmpMarshaledResponseFunc returns a function ready to be used with testing.Run, calling CmpMarshaledResponse behind the scene. As it is intended to be used in conjunction with testing.Run() which names the sub-test, the test name part (args...) is voluntary omitted.
t.Run("Subtest name", tdhttp.CmpMarshaledResponseFunc( tdhttp.Get("/text"), mux.ServeHTTP, tdhttp.Response{ Status: http.StatusOK, }))
See CmpMarshaledResponse documentation for details.
See TestAPI type and its methods for more flexible tests.
func CmpResponse ¶
func CmpResponse(t testing.TB, req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response, args ...interface{}) bool
CmpResponse is used to match a []byte or string response body. The req *http.Request is launched against handler. If expectedResp.Body is non-nil, the response body is converted to []byte or string, depending on the expectedResp.Body type. The response is then tested against expectedResp.
"args..." are optional and allow to name the test, a t.Log() done before starting any test. If len(args) > 1 and the first item of "args" is a string and contains a '%' rune then fmt.Fprintf is used to compose the name, else "args" are passed to fmt.Fprint.
It returns true if the tests succeed, false otherwise.
ok := tdhttp.CmpResponse(t, tdhttp.Get("/test"), myAPI.ServeHTTP, Response{ Status: http.StatusOK, Header: td.ContainsKey("X-Custom-Header"), Body: "OK!\n", }, "/test route")
Status, Header and Body fields of Response struct can all be TestDeep operators as it is for Header field here. Otherwise, Status should be an int, Header a http.Header and Body a []byte or a string.
See TestAPI type and its methods for more flexible tests.
func CmpResponseFunc ¶
func CmpResponseFunc(req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response) func(t *testing.T)
CmpResponseFunc returns a function ready to be used with testing.Run, calling CmpResponse behind the scene. As it is intended to be used in conjunction with testing.Run() which names the sub-test, the test name part (args...) is voluntary omitted.
t.Run("Subtest name", tdhttp.CmpResponseFunc( tdhttp.Get("/text"), mux.ServeHTTP, tdhttp.Response{ Status: http.StatusOK, }))
See CmpResponse documentation for details.
See TestAPI type and its methods for more flexible tests.
func CmpXMLResponse ¶
func CmpXMLResponse(t testing.TB, req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response, args ...interface{}, ) bool
CmpXMLResponse is used to match an XML response body. The req *http.Request is launched against handler. If expectedResp.Body is non-nil, the response body is xml.Unmarshal'ed. The response is then tested against expectedResp.
"args..." are optional and allow to name the test, a t.Log() done before starting any test. If len(args) > 1 and the first item of "args" is a string and contains a '%' rune then fmt.Fprintf is used to compose the name, else "args" are passed to fmt.Fprint.
It returns true if the tests succeed, false otherwise.
ok := tdhttp.CmpXMLResponse(t, tdhttp.Get("/person/42"), myAPI.ServeHTTP, Response{ Status: http.StatusOK, Header: td.ContainsKey("X-Custom-Header"), Body: Person{ ID: 42, Name: "Bob", Age: 26, }, }, "/person/{id} route")
Status, Header and Body fields of Response struct can all be TestDeep operators as it is for Header field here. Otherwise, Status should be an int, Header a http.Header and Body any type encoding/xml can Unmarshal into.
If Status and Header are omitted (or nil), they are not tested.
If Body is omitted (or nil), it means the body response has to be empty. If you want to ignore the body response, use td.Ignore() explicitly.
See TestAPI type and its methods for more flexible tests.
func CmpXMLResponseFunc ¶
func CmpXMLResponseFunc(req *http.Request, handler func(w http.ResponseWriter, r *http.Request), expectedResp Response) func(t *testing.T)
CmpXMLResponseFunc returns a function ready to be used with testing.Run, calling CmpXMLResponse behind the scene. As it is intended to be used in conjunction with testing.Run() which names the sub-test, the test name part (args...) is voluntary omitted.
t.Run("Subtest name", tdhttp.CmpXMLResponseFunc( tdhttp.Get("/xml"), mux.ServeHTTP, tdhttp.Response{ Status: http.StatusOK, Body: JResp{Comment: "expected comment!"}, }))
See CmpXMLResponse documentation for details.
See TestAPI type and its methods for more flexible tests.
func Delete ¶
Delete creates a HTTP DELETE. It is a shortcut for:
NewRequest(http.MethodDelete, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func DeleteJSON ¶
DeleteJSON creates a HTTP DELETE with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". It is a shortcut for:
NewJSONRequest(http.MethodDelete, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func DeleteXML ¶
DeleteXML creates a HTTP DELETE with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". It is a shortcut for:
NewXMLRequest(http.MethodDelete, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func Get ¶
Get creates a new HTTP GET. It is a shortcut for:
NewRequest(http.MethodGet, target, nil, headers...)
See NewRequest for all possible formats accepted in headers.
func Head ¶
Head creates a new HTTP HEAD. It is a shortcut for:
NewRequest(http.MethodHead, target, nil, headers...)
See NewRequest for all possible formats accepted in headers.
func NewJSONRequest ¶
NewJSONRequest creates a new HTTP request with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". Other headers can be added via headers, as in:
req := NewJSONRequest("POST", "/data", body, "X-Foo", "Foo-value", "X-Zip", "Zip-value", )
See NewRequest for all possible formats accepted in headers.
func NewRequest ¶
NewRequest creates a new HTTP request as net/http/httptest.NewRequest does, with the ability to immediately add some headers using string pairs as in:
req := NewRequest("POST", "/pdf", body, "Content-type", "application/pdf", "X-Test", "value", )
or using http.Header as in:
req := NewRequest("POST", "/pdf", body, http.Header{"Content-type": []string{"application/pdf"}}, )
Several header sources are combined:
req := NewRequest("POST", "/pdf", body, "Content-type", "application/pdf", http.Header{"X-Test": []string{"value1"}}, "X-Test", "value2", )
Produce the following http.Header:
http.Header{ "Content-type": []string{"application/pdf"}, "X-Test": []string{"value1", "value2"}, }
A string slice or a map can be flatened as well. As NewRequest() expects ...interface{}, td.Flatten() can help here too:
strHeaders := map[string]string{ "X-Length": "666", "X-Foo": "bar", } req := NewRequest("POST", "/pdf", body, td.Flatten(strHeaders))
Or combined with forms seen above:
req := NewRequest("POST", "/pdf", "Content-type", "application/pdf", http.Header{"X-Test": []string{"value1"}}, td.Flatten(strHeaders), "X-Test", "value2", )
func NewXMLRequest ¶
NewXMLRequest creates a new HTTP request with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". Other headers can be added via headers, as in:
req := NewXMLRequest("POST", "/data", body, "X-Foo", "Foo-value", "X-Zip", "Zip-value", )
See NewRequest for all possible formats accepted in headers.
func Patch ¶
Patch creates a HTTP PATCH. It is a shortcut for:
NewRequest(http.MethodPatch, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func PatchJSON ¶
PatchJSON creates a HTTP PATCH with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". It is a shortcut for:
NewJSONRequest(http.MethodPatch, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func PatchXML ¶
PatchXML creates a HTTP PATCH with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". It is a shortcut for:
NewXMLRequest(http.MethodPatch, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func Post ¶
Post creates a HTTP POST. It is a shortcut for:
NewRequest(http.MethodPost, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func PostForm ¶
PostForm creates a HTTP POST with data's keys and values URL-encoded as the request body. "Content-Type" header is automatically set to "application/x-www-form-urlencoded". Other headers can be added via headers, as in:
req := PostForm("/data", url.Values{ "param1": []string{"val1", "val2"}, "param2": []string{"zip"}, }, "X-Foo", "Foo-value", "X-Zip", "Zip-value", )
See NewRequest for all possible formats accepted in headers.
func PostJSON ¶
PostJSON creates a HTTP POST with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". It is a shortcut for:

NewRequest(http.MethodPut, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
func PutJSON ¶
PutJSON creates a HTTP PUT with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". It is a shortcut for:
NewJSONRequest(http.MethodPut, target, body, headers...)
See NewRequest for all possible formats accepted in headers.
Types ¶
type Response ¶
type Response struct { Status interface{} // Status is the expected status (ignored if nil) Header interface{} // Header is the expected header (ignored if nil) Body interface{} // Body is the expected body (expected to be empty if nil) }
Response is used by Cmp*Response functions to make the HTTP response match easier. Each field, can be a TestDeep operator as well as the exact expected value.
type TestAPI ¶
type TestAPI struct {
// contains filtered or unexported fields
}
TestAPI allows to test one HTTP API. See NewTestAPI function to create a new instance and get some examples of use.
func NewTestAPI ¶
NewTestAPI creates a TestAPI that can be used to test routes of the API behind "handler".
tdhttp.NewTestAPI(t, mux). Get("/test"). CmpStatus(200). CmpBody("OK!")
Several routes can be tested with the same instance as in:
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/test"). CmpStatus(200). CmpBody("OK!") ta.Get("/ping"). CmpStatus(200). CmpBody("pong")
Note that "tb" can be a *testing.T as well as a *td.T.
func (*TestAPI) A ¶
A is a synonym for Anchor. It returns a typed value allowing to anchor the TestDeep operator "operator" in a go classic litteral like a struct, slice, array or map value.
ta := tdhttp.NewTestAPI(tt, mux) ta.Get("/person/42"). CmpStatus(http.StatusOK). CmpJSONBody(Person{ ID: ta.A(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 26, })
See (*td.T).Anchor documentation https://pkg.go.dev/github.com/maxatome/go-testdeep/td#T.Anchor for details.
func (*TestAPI) Anchor ¶
Anchor returns a typed value allowing to anchor the TestDeep operator "operator" in a go classic litteral like a struct, slice, array or map value.
ta := tdhttp.NewTestAPI(tt, mux) ta.Get("/person/42"). CmpStatus(http.StatusOK). CmpJSONBody(Person{ ID: ta.Anchor(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 26, })
See (*td.T).Anchor documentation for details https://pkg.go.dev/github.com/maxatome/go-testdeep/td#T.Anchor
See A method for a shorter synonym of Anchor.
func (*TestAPI) AutoDumpResponse ¶
AutoDumpResponse allows to dump the HTTP response when the first error is encountered after a request.
func (*TestAPI) CmpBody ¶
CmpBody tests the last request response body against expectedBody. expectedBody can be a []byte, a string or a TestDeep operator.
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/test"). CmpStatus(http.StatusOK). CmpBody("OK!\n") ta.Get("/test"). CmpStatus(http.StatusOK). CmpBody(td.Contains("OK"))
It fails if no request has been sent yet.
func (*TestAPI) CmpHeader ¶
CmpHeader tests the last request response header against expectedHeader. expectedHeader can be a http.Header or a TestDeep operator. Keep in mind that if it is a http.Header, it has to match exactly the response header. Often only the presence of a header key is needed:
ta := tdhttp.NewTestAPI(t, mux). PostJSON("/new", map[string]string{"name": "Bob"}). CmdStatus(201). CmpHeader(td.ContainsKey("X-Custom"))
or some specific key, value pairs:
ta.CmpHeader(td.SuperMapOf( http.Header{ "X-Account": []string{"Bob"}, }, td.MapEntries{ "X-Token": td.Re(`^[a-z0-9-]{32}\z`), }), )
Note that CmpHeader calls can be chained:
ta.CmpHeader(td.ContainsKey("X-Account")). CmpHeader(td.ContainsKey("X-Token"))
instead of doing all tests in one call as All operator allows it:
ta.CmpHeader(td.All( td.ContainsKey("X-Account"), td.ContainsKey("X-Token")), )
It fails if no request has been sent yet.
func (*TestAPI) CmpJSONBody ¶
CmpJSONBody tests that the last request response body can be encoding/json.Unmarshall'ed and that it matches expectedBody. expectedBody can be any type encoding/json can Unmarshal into, or a TestDeep operator.
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/person/42"). CmpStatus(http.StatusOK). CmpJSONBody(Person{ ID: 42, Name: "Bob", Age: 26, }) ta.PostJSON("/person", Person{Name: "Bob", Age: 23}). CmpStatus(http.StatusCreated). CmpJSONBody(td.SStruct( Person{ Name: "Bob", Age: 26, }, td.StructFields{ "ID": td.NotZero(), }))
The same with anchoring, and so without td.SStruct():
ta := tdhttp.NewTestAPI(tt, mux) ta.PostJSON("/person", Person{Name: "Bob", Age: 23}). CmpStatus(http.StatusCreated). CmpJSONBody(Person{ ID: ta.Anchor(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 26, })
The same using td.JSON():
ta.PostJSON("/person", Person{Name: "Bob", Age: 23}). CmpStatus(http.StatusCreated). CmpJSONBody(td.JSON(` { "id": NotZero(), "name": "Bob", "age": 26 }`))
It fails if no request has been sent yet.
func (*TestAPI) CmpMarshaledBody ¶
func (t *TestAPI) CmpMarshaledBody(unmarshal func([]byte, interface{}) error, expectedBody interface{}) *TestAPI
CmpMarshaledBody tests that the last request response body can be unmarshalled using unmarhsal function and then, that it matches expectedBody. expectedBody can be any type unmarshal function can handle, or a TestDeep operator.
See CmpJSONBody and CmpXMLBody sources for examples of use.
It fails if no request has been sent yet.
func (*TestAPI) CmpStatus ¶
CmpStatus tests the last request response status against expectedStatus. expectedStatus can be an int to match a fixed HTTP status code, or a TestDeep operator.
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/test"). CmpStatus(http.StatusOK) ta.PostJSON("/new", map[string]string{"name": "Bob"}). CmpStatus(td.Between(200, 202))
It fails if no request has been sent yet.
func (*TestAPI) CmpXMLBody ¶
CmpXMLBody tests that the last request response body can be encoding/xml.Unmarshall'ed and that it matches expectedBody. expectedBody can be any type encoding/xml can Unmarshal into, or a TestDeep operator.
ta := tdhttp.NewTestAPI(t, mux) ta.Get("/person/42"). CmpStatus(http.StatusOK). CmpXMLBody(Person{ ID: 42, Name: "Bob", Age: 26, }) ta.Get("/person/43"). CmpStatus(http.StatusOK). CmpXMLBody(td.SStruct( Person{ Name: "Bob", Age: 26, }, td.StructFields{ "ID": td.NotZero(), }))
The same with anchoring:
ta := tdhttp.NewTestAPI(tt, mux) ta.Get("/person/42"). CmpStatus(http.StatusOK). CmpXMLBody(Person{ ID: ta.Anchor(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 26, })
It fails if no request has been sent yet.
func (*TestAPI) Delete ¶
Delete sends a HTTP DELETE to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) DeleteJSON ¶
DeleteJSON sends a HTTP DELETE with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) DeleteXML ¶
DeleteXML sends a HTTP DELETE with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Failed ¶
Failed returns true if any Cmp* or NoBody method failed since last request sending.
func (*TestAPI) Get ¶
Get sends a HTTP GET to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Head ¶
Head sends a HTTP HEAD to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Name ¶
Name allows to name the series of tests that follow. This name is used as a prefix for all following tests, in case of failure to qualify each test. If len(args) > 1 and the first item of "args" is a string and contains a '%' rune then fmt.Fprintf is used to compose the name, else "args" are passed to fmt.Fprint.
func (*TestAPI) NewJSONRequest ¶
func (t *TestAPI) NewJSONRequest(method, target string, body interface{}, headers ...interface{}) *TestAPI

It fails if no request has been sent yet.
func (*TestAPI) Or ¶
Or executes function "fn" if t.Failed() is true at the moment it is called.
"fn" can have several types:
- func(body string) or func(t *td.T, body string) → "fn" is called with response body as a string. If no response has been received yet, body is ""; - func(body []byte) or func(t *td.T, body []byte) → "fn" is called with response body as a []byte. If no response has been received yet, body is nil; - func(t *td.T, resp *httptest.ResponseRecorder) → "fn" is called with the internal object containing the response. See net/http/httptest for details. If no response has been received yet, resp is nil.
If "fn" type is not one of these types, it panics.
func (*TestAPI) OrDumpResponse ¶
OrDumpResponse dumps the response if at least one previous test failed.
ta := tdhttp.NewTestAPI(t, handler) ta.Get("/foo"). CmpStatus(200). OrDumpResponse(). // if status check failed, dumps the response CmpBody("bar") // if it fails, the response is not dumped ta.Get("/foo"). CmpStatus(200). CmpBody("bar"). OrDumpResponse() // dumps the response if status and/or body checks fail
See AutoDumpResponse method to automatize this dump.
func (*TestAPI) Patch ¶
Patch sends a HTTP PATCH to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PatchJSON ¶
PatchJSON sends a HTTP PATCH with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PatchXML ¶
PatchXML sends a HTTP PATCH with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Post ¶
Post sends a HTTP POST to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PostForm ¶
PostForm sends a HTTP POST with data's keys and values URL-encoded as the request body to the tested API.. "Content-Type" header is automatically set to "application/x-www-form-urlencoded". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PostJSON ¶
PostJSON sends a HTTP POST with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PostXML ¶
PostXML sends a HTTP POST with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Put ¶
Put sends a HTTP PUT to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PutJSON ¶
PutJSON sends a HTTP PUT with body marshaled to JSON. "Content-Type" header is automatically set to "application/json". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) PutXML ¶
PutXML sends a HTTP PUT with body marshaled to XML. "Content-Type" header is automatically set to "application/xml". Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
See NewRequest for all possible formats accepted in headers.
func (*TestAPI) Request ¶
Request sends a new HTTP request to the tested API. Any Cmp* or NoBody methods can now be called.
Note that Failed() status is reset just after this call.
func (*TestAPI) SentAt ¶
SentAt returns the time just before the last request is handled. It can be used to check the time a route sets and returns, as in:
ta.PostJSON("/person/42", Person{Name: "Bob", Age: 23}). CmpStatus(http.StatusCreated). CmpJSONBody(Person{ ID: ta.A(td.NotZero(), uint64(0)).(uint64), Name: "Bob", Age: 23, CreatedAt: ta.A(td.Between(ta.SentAt(), time.Now())).(time.Time), })
checks that CreatedAt is included between the time when the request has been sent, and the time when the comparison occurs.
func (*TestAPI) With ¶
With creates a new *TestAPI instance copied from "t", but resetting the testing.TB instance the tests are based on to "tb". The returned instance is independent from "t", sharing only the same handler.
It is typically used when the *TestAPI instance is "reused" in sub-tests, as in:
func TestMyAPI(t *testing.T) { ta := tdhttp.NewTestAPI(t, MyAPIHandler()) ta.Get("/test").CmpStatus(200) t.Run("errors", func (t *testing.T) { ta := ta.With(t) ta.Get("/test?bad=1").CmpStatus(400) ta.Get("/test?bad=buzz").CmpStatus(400) } ta.Get("/next").CmpStatus(200) }
Note that "tb" can be a *testing.T as well as a *td.T.
See Run method for another way to handle subtests.
