Overview ¶

Example Usage
Assertions

Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.

Example Usage ¶

The following is a complete example using assert in a standard test function:

import [ "testing" "github.com/stretchr/testify/assert" ] func TestSomething[t *testing.T] { var a string = "Hello" var b string = "Hello" assert.Equal[t, a, b, "The two words should be the same."] }

if you assert many times, use the format below:

import [ "testing" "github.com/stretchr/testify/assert" ] func TestSomething[t *testing.T] { assert := assert.New[t] var a string = "Hello" var b string = "Hello" assert.Equal[a, b, "The two words should be the same."] }

Assertions ¶

Assertions allow you to easily write test code, and are global funcs in the `assert` package. All assertion functions take, as the first argument, the `*testing.T` object provided by the testing framework. This allows the assertion funcs to write the failings and other details to the correct place.

Every assertion function also takes an optional string message as the final argument, allowing custom error messages to be appended to the message the assertion method outputs.

Variables ¶

View Sourcevar AnError = errors.New["assert.AnError general error for testing"]

AnError is an error 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 an array of strings containing the file and line number of each stack frame leading from the current test to the assert call that failed.

func Condition ¶

func Condition[t TestingT, comp Comparison, msgAndArgs ...interface{}] bool

Condition uses a Comparison to assert a complex condition.

func Conditionf ¶ added in v1.2.0

func Conditionf[t TestingT, comp Comparison, msg string, args ...interface{}] bool

Conditionf uses a Comparison to assert a complex condition.

func Contains ¶

func Contains[t TestingT, s, contains interface{}, msgAndArgs ...interface{}] bool

Contains asserts that the specified string, list[array, slice...] or map contains the specified substring or element.

assert.Contains[t, "Hello World", "World"] assert.Contains[t, ["Hello", "World"], "World"] assert.Contains[t, {"Hello": "World"}, "Hello"]

func Containsf ¶ added in v1.2.0

func Containsf[t TestingT, s interface{}, contains interface{}, msg string, args ...interface{}] bool

Containsf asserts that the specified string, list[array, slice...] or map contains the specified substring or element.

assert.Containsf[t, "Hello World", "World", "error message %s", "formatted"] assert.Containsf[t, ["Hello", "World"], "World", "error message %s", "formatted"] assert.Containsf[t, {"Hello": "World"}, "Hello", "error message %s", "formatted"]

func DirExists ¶ added in v1.2.0

func DirExists[t TestingT, path string, msgAndArgs ...interface{}] bool

DirExists checks whether a directory exists in the given path. It also fails if the path is a file rather a directory or there is an error checking whether it exists.

func DirExistsf ¶ added in v1.2.0

func DirExistsf[t TestingT, path string, msg string, args ...interface{}] bool

DirExistsf checks whether a directory exists in the given path. It also fails if the path is a file rather a directory or there is an error checking whether it exists.

func ElementsMatch ¶ added in v1.2.0

func ElementsMatch[t TestingT, listA, listB interface{}, msgAndArgs ...interface{}] [ok bool]

ElementsMatch asserts that the specified listA[array, slice...] is equal to specified listB[array, slice...] ignoring the order of the elements. If there are duplicate elements, the number of appearances of each of them in both lists should match.

assert.ElementsMatch[t, [1, 3, 2, 3], [1, 3, 3, 2]]

func ElementsMatchf ¶ added in v1.2.0

ErrorAssertionFunc is a common function prototype when validating an error value. Can be useful for table driven tests.

Example ¶

t := &testing.T{} // provided by test dumbParseNum := func[input string, v interface{}] error { return json.Unmarshal[[]byte[input], v] } tests := []struct { name string arg string assertion ErrorAssertionFunc }{ {"1.2 is number", "1.2", NoError}, {"1.2.3 not number", "1.2.3", Error}, {"true is not number", "true", Error}, {"3 is number", "3", NoError}, } for _, tt := range tests { t.Run[tt.name, func[t *testing.T] { var x float64 tt.assertion[t, dumbParseNum[tt.arg, &x]] }] } Output:

type PanicTestFunc ¶

type PanicTestFunc func[]

PanicTestFunc defines a func that should be passed to the assert.Panics and assert.NotPanics methods, and represents a simple func that takes no arguments, and returns nothing.

type TestingT ¶

type TestingT interface { Errorf[format string, args ...interface{}] }

TestingT is an interface wrapper around *testing.T

type ValueAssertionFunc ¶ added in v1.2.2

type ValueAssertionFunc func[TestingT, interface{}, ...interface{}] bool

ValueAssertionFunc is a common function prototype when validating a single value. Can be useful for table driven tests.

Example ¶

t := &testing.T{} // provided by test dumbParse := func[input string] interface{} { var x interface{} json.Unmarshal[[]byte[input], &x] return x } tests := []struct { name string arg string assertion ValueAssertionFunc }{ {"true is not nil", "true", NotNil}, {"empty string is nil", "", Nil}, {"zero is not nil", "0", NotNil}, {"zero is zero", "0", Zero}, {"false is zero", "false", Zero}, } for _, tt := range tests { t.Run[tt.name, func[t *testing.T] { tt.assertion[t, dumbParse[tt.arg]] }] } Output:
