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.

Functions

func Condition

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

    Condition uses a Comparison to assert a complex condition.

    func Conditionf

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

      Conditionf uses a Comparison to assert a complex condition.

      func Contains

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

        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

        func Containsf(t TestingT, s interface{}, contains interface{}, msg string, args ...interface{})

          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

          func DirExists(t TestingT, path string, msgAndArgs ...interface{})

            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

            func DirExistsf(t TestingT, path string, msg string, args ...interface{})

              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

              func ElementsMatch(t TestingT, listA interface{}, listB interface{}, msgAndArgs ...interface{})

                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])
