Documentation

Overview

Package require implements the same assertions as the `assert` package but stops test execution when a test fails.

Example Usage

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

import (
  "testing"
  "github.com/stretchr/testify/require"
)

func TestSomething(t *testing.T) {

  var a string = "Hello"
  var b string = "Hello"

  require.Equal(t, a, b, "The two words should be the same.")

}

Assertions

The `require` package have same global functions as in the `assert` package, but instead of returning a boolean result they call `t.FailNow()`.

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.
