Testify - Thou shalt write tests

Go code (golang) set of packages that provide many tools for testifying that your code will behave as you intend.

• Easy assertions
• Mocking
• HTTP response trapping

Assert package

The assert package provides some helpful methods that allow you to write better test code in Go.

See it in action:

func TestSomething(t *testing.T) {

  assert.Equal(t, 123, 123, "they should be equal")

  assert.Nil(t, object)

  if assert.NotNil(t, object) {

    assert.Equal(t, "Something", object.Value)

  }

}

• Every assert func takes the testing.T object as the first argument. This is how it writes the errors out through the normal go test capabilities.
• Every assert func returns a bool indicating whether the assertion was successful or not, this is useful for if you want to go on making further assertions under certain conditions.
