Test Docker Image

The Docker image used by the tests is runatlantis/testing-env. It's built by the Dockerfie in this directory.

The image is automatically built by Docker Hub on merges to master.

To update the image, create a pull request that updates the Dockerfile and get it merged to master.

Wait until the build at https://hub.docker.com/repository/docker/runatlantis/testing-env/builds finishes and then scroll to the bottom to find output like:

01216b26cd75183360909a50217a39d55a9265e7: digest: sha256:9c26943a576bf8aaa7a3790f3f8677c68747114e027cfbc361717f49b958e2d1 size: 4741
Build finished

The sha 01216b26cd75183360909a50217a39d55a9265e7 is the tag of the latest image.

In .circleci/config.yml, update the image to reference the new tag:

jobs:
  test:
    docker:
-    - image: runatlantis/testing-env:<old tag>
+    - image: runatlantis/testing-env:<new tag>

And open up a PR.

Functions

func Assert

func Assert(tb testing.TB, condition bool, msg string, v ...interface{})

Assert fails the test if the condition is false. Taken from https://github.com/benbjohnson/testing.

func Contains

func Contains(tb testing.TB, exp interface{}, slice []string)

Contains fails the test if the slice doesn't contain the expected element

func DirStructure

func DirStructure(t *testing.T, structure map[string]interface{}) (string, func())

DirStructure creates a directory structure in a temporary directory. structure describes the dir structure. If the value is another map, then the key is the name of a directory. If the value is nil, then the key is the name of a file. If val is a string then key is a file name and val is the file's content. It returns the path to the temp directory containing the defined structure and a cleanup function to delete the directory. Example usage:

	versionConfig := `
 terraform {
	  required_version = "= 0.12.8"
 }
 `
	tmpDir, cleanup := DirStructure(t, map[string]interface{}{
		"pulldir": map[string]interface{}{
			"project1": map[string]interface{}{
				"main.tf": nil,
			},
			"project2": map[string]interface{}{,
				"main.tf": versionConfig,
			},
		},
	})
 defer cleanup()

func Equals

func Equals(tb testing.TB, exp, act interface{})

Equals fails the test if exp is not equal to act. Taken from https://github.com/benbjohnson/testing.

func ErrContains

func ErrContains(tb testing.TB, substr string, act error)

ErrContains fails the test if act is nil or act.Error() does not contain substr.

func ErrEquals

func ErrEquals(tb testing.TB, exp string, act error)

ErrEquals fails the test if act is nil or act.Error() != exp

func Ok

func Ok(tb testing.TB, err error)

Ok fails the test if an err is not nil. Taken from https://github.com/benbjohnson/testing.

func ResponseContains

func ResponseContains(t *testing.T, r *httptest.ResponseRecorder, status int, bodySubstr string)

func TempDir

func TempDir(t *testing.T) (string, func())

TempDir creates a temporary directory and returns its path along with a cleanup function to be called via defer, ex:

dir, cleanup := TempDir()
defer cleanup()
