Variables

var AnError error = errors.New("assert.AnError general error for testing.")

AnError is an erorr instance useful for testing. If the code does not care about error specifics, and only needs to return the error for example, this error should be used to make the test code more readable.


Functions

func CallerInfo

func CallerInfo() string

CallerInfo returns a string containing the file and line number of the assert call that failed.

func Condition

func Condition(t TestingT, comp Comparison, msgAndArgs ...interface{}) bool

Uses a Comparison to assert a complex condition.

func Contains

func Contains(t TestingT, s, contains string, msgAndArgs ...interface{}) bool

Contains asserts that the specified string contains the specified substring.

assert.Contains(t, "Hello World", "World", "But 'Hello World' does contain 'World'")

Returns whether the assertion was successful (true) or not (false).

func Empty

func Empty(t TestingT, object interface{}, msgAndArgs ...interface{}) bool

Empty asserts that the specified object is empty. I.e. nil, "", false, 0 or a slice with len == 0.

assert.Empty(t, obj)

Returns whether the assertion was successful (true) or not (false).

func Equal

func Equal(t TestingT, expected, actual interface{}, msgAndArgs ...interface{}) bool

Equal asserts that two objects are equal.

assert.Equal(t, 123, 123, "123 and 123 should be equal")

Returns whether the assertion was successful (true) or not (false).

func Error

func Error(t TestingT, theError error, msgAndArgs ...interface{}) bool

Error asserts that a function returned an error (i.e. not `nil`).

  actualObj, err := SomeFunction()
  if assert.Error(t, err, "An error was expected") {
	   assert.Equal(t, err, expectedError)
  }

Returns whether the assertion was successful (true) or not (false).

func Exactly

func Exactly(t TestingT, expected, actual interface{}, msgAndArgs ...interface{}) bool

Exactly asserts that two objects are equal is value and type.

assert.Exactly(t, int32(123), int64(123), "123 and 123 should NOT be equal")

Returns whether the assertion was successful (true) or not (false).

func Fail

func Fail(t TestingT, failureMessage string, msgAndArgs ...interface{}) bool

Fail reports a failure through

func False

func False(t TestingT, value bool, msgAndArgs ...interface{}) bool

False asserts that the specified value is true.

assert.False(t, myBool, "myBool should be false")

Returns whether the assertion was successful (true) or not (false).

func Implements

func Implements(t TestingT, interfaceObject interface{}, object interface{}, msgAndArgs ...interface{}) bool

Implements asserts that an object is implemented by the specified interface.

assert.Implements(t, (*MyInterface)(nil), new(MyObject), "MyObject")

func IsType

func IsType(t TestingT, expectedType interface{}, object interface{}, msgAndArgs ...interface{}) bool

IsType asserts that the specified objects are of the same type.

func Nil

func Nil(t TestingT, object interface{}, msgAndArgs ...interface{}) bool

Nil asserts that the specified object is nil.

assert.Nil(t, err, "err should be nothing")

Returns whether the assertion was successful (true) or not (false).

func NoError

func NoError(t TestingT, theError error, msgAndArgs ...interface{}) bool

NoError asserts that a function returned no error (i.e. `nil`).

  actualObj, err := SomeFunction()
  if assert.NoError(t, err) {
	   assert.Equal(t, actualObj, expectedObj)
  }

Returns whether the assertion was successful (true) or not (false).

func NotContains

func NotContains(t TestingT, s, contains string, msgAndArgs ...interface{}) bool

NotContains asserts that the specified string does NOT contain the specified substring.

assert.NotContains(t, "Hello World", "Earth", "But 'Hello World' does NOT contain 'Earth'")

Returns whether the assertion was successful (true) or not (false).

func NotEmpty

func NotEmpty(t TestingT, object interface{}, msgAndArgs ...interface{}) bool

Empty asserts that the specified object is NOT empty. I.e. not nil, "", false, 0 or a slice with len == 0.

if assert.NotEmpty(t, obj) {

assert.Equal(t, "two", obj[1])

}

Returns whether the assertion was successful (true) or not (false).

func NotEqual

func NotEqual(t TestingT, expected, actual interface{}, msgAndArgs ...interface{}) bool

NotEqual asserts that the specified values are NOT equal.

assert.NotEqual(t, obj1, obj2, "two objects shouldn't be equal")

Returns whether the assertion was successful (true) or not (false).

func NotNil

func NotNil(t TestingT, object interface{}, msgAndArgs ...interface{}) bool

Returns whether the assertion was successful (true) or not (false).

func NotPanics

func NotPanics(t TestingT, f PanicTestFunc, msgAndArgs ...interface{}) bool

NotPanics asserts that the code inside the specified PanicTestFunc does NOT panic.

type TestingT

type TestingT interface {
	Errorf(format string, args ...interface{})
