check

Helpers to complement Go testing package.

Write tests with ease and fun!

This package is like testify/assert on steroids. :)

Features

• Compelling output from failed tests:
  • Very easy-to-read dumps for expected and actual values.
  • Same text diff you loved in testify/assert.
  • Also visual diff in GoConvey web UI, if you use it (recommended).
• Statistics with amount of passed/failed checks.
• Colored output in terminal.
• 100% compatible with testing package - check package just provide convenient wrappers for *testing.T methods and doesn't introduce new concepts like BDD, custom test suite or unusual execution flow.
• All checks you may ever need! :)
• Very easy to add your own check functions.
• Concise, handy and consistent API, without dot-import!

Quickstart

Just wrap each (including subtests) *testing.T using check.T() and write tests as usually with testing package. Call new methods provided by this package to have more clean/concise test code and cool dump/diff.

import "github.com/powerman/check"

func TestSomething(tt *testing.T) {
	t := check.T(tt)
	t.Equal(2, 2)
	t.Log("You can use new t just like usual *testing.T")
	t.Run("Subtests/Parallel example", func(tt *testing.T) {
		t := check.T(tt)
		t.Parallel()
		t.NotEqual(2, 3, "should not be 3!")
		obj, err := NewObj()
		if t.Nil(err) {
			t.Match(obj.field, `^\d+$`)
		}
	})
}

To get optional statistics about executed checkers add:

func TestMain(m *testing.M) { check.TestMain(m) }

When use goconvey tool, to get nice diff in web UI add:

import _ "github.com/smartystreets/goconvey/convey"
