Functions

func DiscardStdout

func DiscardStdout() error

DiscardStdout Discard os.Stdout output Usage:

DiscardStdout()
fmt.Println("Hello, playground")
RestoreStdout()

func MockEnvValue

func MockEnvValue(key, val string, fn func(nv string))

MockEnvValue will store old env value, set new val. will restore old value on end.

func MockEnvValues

func MockEnvValues(kvMap map[string]string, fn func())

MockEnvValues will store old env value, set new val. will restore old value on end.

func MockOsEnv

func MockOsEnv(mp map[string]string, fn func())

MockOsEnv by env map data. clear all old ENV data, use given data map, will recover old ENV after fn run.

func MockOsEnvByText

func MockOsEnvByText(envText string, fn func())

MockOsEnvByText by env text string. clear all old ENV data, use given data map, will recover old ENV after fn run.

func MockRequest

func MockRequest(h http.Handler, method, path string, data *MD) *httptest.ResponseRecorder

MockRequest mock an HTTP Request

Usage:

handler := router.New()
res := MockRequest(handler, "GET", "/path", nil)

// with data 1
body := strings.NewReader("string ...")
res := MockRequest(handler, "POST", "/path", &MD{
	Body: body,
	Headers: M{"x-head": "val"}
})

// with data 2
res := MockRequest(handler, "POST", "/path", &MD{
	BodyString: "data string",
	Headers: M{"x-head": "val"}
})

func NewHttpRequest

func NewHttpRequest(method, path string, data *MD) *http.Request

NewHttpRequest for http testing Usage:

req := NewHttpRequest(handler, "GET", "/path", nil)

// with data 1
body := strings.NewReader("string ...")
req := NewHttpRequest(handler, "POST", "/path", &MD{
	Body: body,
	Headers: M{"x-head": "val"}
})

// with data 2
req := NewHttpRequest(handler, "POST", "/path", &MD{
	BodyString: "data string",
	Headers: M{"x-head": "val"}
})

func RestoreStderr

func RestoreStderr() (s string)

RestoreStderr restore os.Stderr

func RestoreStdout

func RestoreStdout() (s string)

RestoreStdout restore os.Stdout

func RewriteStderr

func RewriteStderr()

RewriteStderr rewrite os.Stderr Usage:

RewriteStderr()
fmt.Fprintln(os.Stderr, "Hello, playground")
msg := RestoreStderr()

func RewriteStdout

func RewriteStdout()

RewriteStdout rewrite os.Stdout Usage:

RewriteStdout()
fmt.Println("Hello, playground")
msg := RestoreStdout()

Types

type M

type M map[string]string

M short name for map

type MD

type MD struct {
	// Headers headers
	Headers M
	// Body body. eg: strings.NewReader("name=inhere")
	Body io.Reader
	// BodyString quick add body.
	BodyString string
	// BeforeSend callback
	BeforeSend func(req *http.Request)
}

MD simple request data
