Overview

Oh the stack trace scanning! The density of comments in this file is evidence that the code doesn't exactly explain itself. Tread with care...

Package convey contains all of the public-facing entry points to this project. This means that it should never be required of the user to import any other packages from this project as they serve internal purposes.

Functions

func Convey

func Convey(items ...interface{})

Convey is the method intended for use when declaring the scopes of a specification. Each scope has a description and a func() which may contain other calls to Convey(), Reset() or Should-style assertions. Convey calls can be nested as far as you see fit.

IMPORTANT NOTE: The top-level Convey() within a Test method must conform to the following signature:

Convey(description string, t *testing.T, action func())

All other calls should like like this (no need to pass in *testing.T):

Convey(description string, action func())

Don't worry, the goconvey will panic if you get it wrong so you can fix it.

All Convey()-blocks also take an optional parameter of FailureMode which sets how goconvey should treat failures for So()-assertions in the block and nested blocks. See the constants in this file for the available options.

By default it will inherit from its parent block and the top-level blocks start with setting of FailureHalts.

This parameter is inserted before the block itself:

Convey(description string, t *testing.T, mode FailureMode, action func())
Convey(description string, mode FailureMode, action func())

See the examples package for, well, examples.

func FocusConvey

func FocusConvey(items ...interface{})

FocusConvey is has the inverse effect of SkipConvey. If the top-level Convey is changed to `FocusConvey`, only nested scopes that are defined with FocusConvey will be run. The rest will be ignored completely. This is handy when debugging a large suite that runs a misbehaving function repeatedly as you can disable all but one of that function without swaths of `SkipConvey` calls, just a targeted chain of calls to FocusConvey.

func Print

func Print(items ...interface{}) (written int, err error)

Print is analogous to fmt.Print (and it even calls fmt.Print). It ensures that output is aligned with the corresponding scopes in the web UI.

func Printf

func Printf(format string, items ...interface{}) (written int, err error)

Print is analogous to fmt.Printf (and it even calls fmt.Printf). It ensures that output is aligned with the corresponding scopes in the web UI.

func Println

func Println(items ...interface{}) (written int, err error)

Print is analogous to fmt.Println (and it even calls fmt.Println). It ensures that output is aligned with the corresponding scopes in the web UI.

func Reset

func Reset(action func())

Reset registers a cleanup function to be run after each Convey() in the same scope. See the examples package for a simple use case.

func SetDefaultFailureMode

func SetDefaultFailureMode(mode FailureMode)

SetDefaultFailureMode allows you to specify the default failure mode for all Convey blocks. It is meant to be used in an init function to allow the default mode to be changd across all tests for an entire packgae but it can be used anywhere.

func SkipConvey

func SkipConvey(items ...interface{})

SkipConvey is analagous to Convey except that the scope is not executed (which means that child scopes defined within this scope are not run either). The reporter will be notified that this step was skipped.

func SkipSo

func SkipSo(stuff ...interface{})

SkipSo is analagous to So except that the assertion that would have been passed to So is not executed and the reporter is notified that the assertion was skipped.

func So

func So(actual interface{}, assert assertion, expected ...interface{})

So is the means by which assertions are made against the system under test. The majority of exported names in the assertions package begin with the word 'Should' and describe how the first argument (actual) should compare with any of the final (expected) arguments. How many final arguments are accepted depends on the particular assertion that is passed in as the assert argument. See the examples package for use cases and the assertions package for documentation on specific assertion methods.

Types

type FailureMode

type FailureMode string

FailureMode is a type which determines how the So() blocks should fail if their assertion fails. See constants further down for acceptable values

const (

	// FailureContinues is a failure mode which prevents failing
	// So()-assertions from halting Convey-block execution, instead
	// allowing the test to continue past failing So()-assertions.
	FailureContinues FailureMode = "continue"

	// FailureHalts is the default setting for a top-level Convey()-block
	// and will cause all failing So()-assertions to halt further execution
	// in that test-arm and continue on to the next arm.
	FailureHalts FailureMode = "halt"

	// FailureInherits is the default setting for failure-mode, it will
	// default to the failure-mode of the parent block. You should never
	// need to specify this mode in your tests..
	FailureInherits FailureMode = "inherits"
)
