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/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

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.
