Functions

func WriteYarnRCForTest

func WriteYarnRCForTest(root string) error

WriteYarnRCForTest writes a .yarnrc file which sets global configuration for every yarn inovcation. We use this to work around some test issues we see in Travis.

Types

type Environment

type Environment struct {
	*testing.T

	// RootPath is a new temp directory where the environment starts.
	RootPath string
	// Current working directory.
	CWD string
}

Environment is an extension of the testing.T type that provides support for a test environment on the local disk. The Environment has a root directory (e.g. a newly created temp folder) and a current working directory (to virtually change directories).

func NewEnvironment

func NewEnvironment(t *testing.T) *Environment

NewEnvironment returns a new Environment object, located in a temp directory.

func (*Environment) DeleteEnvironment

func (e *Environment) DeleteEnvironment()

DeleteEnvironment deletes the environment's RootPath, and everything underneath it.

func (*Environment) DeleteIfNotFailed

func (e *Environment) DeleteIfNotFailed()

DeleteIfNotFailed deletes the environment's RootPath if the test hasn't failed. Otherwise keeps the files around for aiding debugging.

func (*Environment) GetCommandResults

func (e *Environment) GetCommandResults(t *testing.T, command string, args ...string) (string, string, error)

GetCommandResults runs the given command and args in the Environments CWD, returning STDOUT, STDERR, and the result of os/exec.Command{}.Run.

func (*Environment) ImportDirectory

func (e *Environment) ImportDirectory(path string)

ImportDirectory copies a folder into the test environment.

func (*Environment) LocalURL

func (e *Environment) LocalURL() string

LocalURL returns a URL that uses the "fire and forget", storing its data inside the test folder (so multiple tests) may reuse stack names.

func (*Environment) PathExists

func (e *Environment) PathExists(p string) bool

PathExists returns whether or not a file or directory exists relative to Environment's working directory.

func (*Environment) RunCommand

func (e *Environment) RunCommand(cmd string, args ...string) (string, string)

RunCommand runs the command expecting a zero exit code, returning stdout and stderr.

func (*Environment) RunCommandExpectError

func (e *Environment) RunCommandExpectError(cmd string, args ...string) (string, string)

RunCommandExpectError runs the command expecting a non-zero exit code, returning stdout and stderr.

func (*Environment) WriteTestFile

func (e *Environment) WriteTestFile(filename string, contents string)

WriteTestFile writes a new test file relative to the Environment's CWD with the given contents. Aborts the underlying test on any errors.
