Documentation

Overview

Package test contains simple test helpers that should not have any dependencies on horizon's packages. think constants, custom matchers, generic helpers etc.

Functions

func Context

func Context() context.Context

Context provides a context suitable for testing in tests that do not create a full App instance (in which case your tests should be using the app's context). This context has a logger bound to it suitable for testing.

func Database

func Database(t *testing.T) *sqlx.DB

Database returns a connection to the horizon test database

DEPRECATED: use `Horizon()` from test/db package

func DatabaseURL

func DatabaseURL() string

DatabaseURL returns the database connection the url any test use when connecting to the history/horizon database

DEPRECATED: use `HorizonURL()` from test/db package

func OverrideLogger

func OverrideLogger(l *log.Entry)

OverrideLogger sets the default logger used by horizon to `l`. This is used by the testing system so that we can collect output from logs during test runs. Panics if the logger is already overridden.

func RequestHelperRaw

func RequestHelperRaw(r *http.Request)

func RequestHelperStreaming

func RequestHelperStreaming(r *http.Request)

func ResetHorizonDB

func ResetHorizonDB(t *testing.T, db *sqlx.DB)

ResetHorizonDB sets up a new horizon database with empty tables

func RestoreLogger

func RestoreLogger()

RestoreLogger restores the default horizon logger after it is overridden using a call to `OverrideLogger`. Panics if the default logger is not presently overridden.

func StellarCoreDatabase

func StellarCoreDatabase(t *testing.T) *sqlx.DB

StellarCoreDatabase returns a connection to the stellar core test database

DEPRECATED: use `StellarCore()` from test/db package

func StellarCoreDatabaseURL

func StellarCoreDatabaseURL() string

StellarCoreDatabaseURL returns the database connection the url any test use when connecting to the stellar-core database

DEPRECATED: use `StellarCoreURL()` from test/db package

Types

type Assertions

type Assertions struct {
	*assert.Assertions
}

Assertions provides an assertions helper. Custom assertions for this package can be defined as methods on this struct. foo

func (*Assertions) PageOf

func (a *Assertions) PageOf(length int, body *bytes.Buffer) bool

func (*Assertions) Problem

func (a *Assertions) Problem(body *bytes.Buffer, expected problem.P) bool

Problem asserts that `body` is a serialized problem equal to `expected`, using Type and Status to compare for equality.

func (*Assertions) ProblemType

func (a *Assertions) ProblemType(body *bytes.Buffer, typ string) bool

ProblemType asserts that the provided `body` is a JSON serialized problem whose type is `typ`

type RequestHelper

type RequestHelper interface {
	Get(string, ...func(*http.Request)) *httptest.ResponseRecorder
	Post(string, url.Values, ...func(*http.Request)) *httptest.ResponseRecorder
}

func NewRequestHelper

func NewRequestHelper(router *chi.Mux) RequestHelper

type StaticMockServer

type StaticMockServer struct {
	*httptest.Server
	LastRequest *http.Request
}

StaticMockServer is a test helper that records it's last request

func NewStaticMockServer

func NewStaticMockServer(response string) *StaticMockServer

NewStaticMockServer creates a new mock server that always responds with `response`

type T

type T struct {
	T          *testing.T
	Assert     *assert.Assertions
	Require    *require.Assertions
	Ctx        context.Context
	HorizonDB  *sqlx.DB
	CoreDB     *sqlx.DB
	Logger     *log.Entry
	LogMetrics *logmetrics.Metrics
	LogBuffer  *bytes.Buffer
}

T provides a common set of functionality for each test in horizon

func Start

func Start(t *testing.T) *T

Start initializes a new test helper object and conceptually "starts" a new test

func (*T) CoreSession

func (t *T) CoreSession() *db.Session

CoreSession returns a db.Session instance pointing at the stellar core test database

func (*T) Finish

func (t *T) Finish()

Finish finishes the test, logging any accumulated horizon logs to the logs output

func (*T) HorizonSession

func (t *T) HorizonSession() *db.Session

HorizonSession returns a db.Session instance pointing at the horizon test database

func (*T) LoadLedgerStatus

func (t *T) LoadLedgerStatus() ledger.Status

LoadLedgerStatus loads ledger state from the core db(or panicing on failure).

func (*T) Scenario

func (t *T) Scenario(name string) ledger.Status

Scenario loads the named sql scenario into the database

func (*T) ScenarioWithoutHorizon

func (t *T) ScenarioWithoutHorizon(name string) ledger.Status

ScenarioWithoutHorizon loads the named sql scenario into the database

func (*T) UnmarshalExtras

func (t *T) UnmarshalExtras(r io.Reader) map[string]string

UnmarshalExtras extracts and returns extras content

func (*T) UnmarshalNext

func (t *T) UnmarshalNext(r io.Reader) string

UnmarshalNext extracts and returns the next link

func (*T) UnmarshalPage

func (t *T) UnmarshalPage(r io.Reader, dest interface{}) hal.Links

UnmarshalPage populates dest with the records contained in the json-encoded page in r
