go-assert

testing assert helper package.

Documentation ¶

Overview ¶

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/chyroc/go-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/chyroc/go-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 Source

var 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 ¶ added in v0.3.0

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 ¶ added in v0.3.0

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

Condition uses a Comparison to assert a complex condition.

func Conditionf ¶ added in v0.3.0

func Conditionf(t TestingT, comp Comparison, msg string, args ...interface{}) bool

Conditionf uses a Comparison to assert a complex condition.

func Contains ¶ added in v0.3.0

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 v0.3.0

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 v0.3.0

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 v0.3.0

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 v0.3.0

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])
