assert

assert

assert implements functions for making assertions in tests.

Installation

The recommended way to install assert is with dep.

dep ensure -add github.com/dapr-project/assert@v1.0.0

Where v1.0.0 is the version you want to pin to. Alternatively you can go get the package into your $GOPATH.

go get -u github.com/dapr-project/assert

Once installed you can import into your project.

import "github.com/dapr-project/assert"

Usage

Use the assert.OK() function inside to assert expected results.

func TestMax(t *testing.T) {
  max := math.Max(1.0, 3.0)
  assert.OK(t, max == 3.0, "max isn't 3.0")
}

Use the assert.Includes() function to assert an element is included in a list.

func TestSplit(t *testing.T) {
  words := strings.Split("hello world", " ")
  assert.Includes(t, words, "hello", "words excludes 'hello'")
}

Use the assert.Excludes() function to assert an element is excluded from a list.

func TestSplit(t *testing.T) {
  words := strings.Split("hello world", " ")
  assert.Excludes(t, words, "foobar", "words includes 'foobar'")
}

Use the assert.Unique() function to assert an element is only included once in a list.

func TestSplit(t *testing.T) {
  letters := strings.Split("hello", "")
  assert.Unique(t, letters, "h", "letters includes 'h' multiple times")
}
