Overview

Package integration contains helpers for integration testing.

The integration test package should normally be used from within a file that does not build unless integration tests are being run: 

//go:build integration

It should also normally be used from within a test containing the term "Integration". The build constraint ensures that we don't run integration tests when we only want to run unit tests and the test name ensures that we don't run unit tests when we only want to run integration tests. For example, a simple test of sending a ping might be called TestIntegrationSendPing.

Tests can be setup by importing the various packages under this package such as "prosody" and "ejabberd". To setup a test against a server the "Test" function should be used and configured with the general options provided in this package and the server specific options provided in the server's package. This creates a SubtestRunner which can be called multiple times to spin up servers with the provided configuration and run one or more subtests against them. For example, running two tests against prosody and one against ejabberd might look like the following: 

func TestIntegrationSendPing(t *testing.T) {
	prosodyRun := prosody.Test(context.TODO(), t,
		integration.Log(),
		prosody.ListenC2S(),
	)
	prosodyRun(integrationSendPing)
	prosodyRun(integrationRecvPing)

	ejabberdRun := ejabberd.Test(context.TODO(), t,
		integration.Log(),
		ejabberd.ListenC2S(),
	)
	ejabberdRun(integrationSendPing)
}

For more information see the SubtestRunner type and the various Option functions.

The SubtestRunner passes each call a Cmd. This is a reprsentation of the command that is beingn run (ie. the server or client we're testing against) and provides you with the information you'll need to connect and communicate with the command. For example, in the ping example above the subtest being run might use Cmd's DialClient shortcut to quickly create a connection to the prosody server spun up for the test. 

func integrationSendPing(ctx context.Context, t *testing.T, cmd *integration.Cmd) {
	j, pass := cmd.User()
	session, err := cmd.DialClient(ctx, j, t,
		xmpp.StartTLS(&tls.Config{
			InsecureSkipVerify: true,
		}),
		xmpp.SASL("", pass, sasl.Plain),
		xmpp.BindResource(),
	)

For more information see the Cmd type.

Types

type Cmd 

type Cmd struct {
	*exec.Cmd

	// Config is meant to be used by internal packages like prosody and ejabberd
	// to store their internal representation of the config before writing it out.
	Config interface{}
	// contains filtered or unexported fields
}

Cmd is an external command being prepared or run.

A Cmd cannot be reused after calling its Run, Output or CombinedOutput methods.

func New 

func New(ctx context.Context, name string, opts ...Option) (*Cmd, error)

New creates a new, unstarted, command.

The provided context is used to kill the process (by calling os.Process.Kill) if the context becomes done before the command completes on its own.

func (*Cmd) C2SAddr added in v0.18.0 

func (cmd *Cmd) C2SAddr() (net.Addr, string)

C2SAddr returns the client-to-server address and network.

func (*Cmd) C2SListen

func (*Cmd) Close 

func (cmd *Cmd) Close() error

Close kills the command if it is still running and cleans up any temporary resources that were created.

func (*Cmd) ComponentAddr added in v0.18.0 

func (cmd *Cmd) ComponentAddr() (net.Addr, string)

func (*Cmd) ConfigDir 

func (cmd *Cmd) ConfigDir() string

ConfigDir returns the temporary directory used to store config files.

func (*Cmd) Conn added in v0.18.0 

func (cmd *Cmd) Conn(ctx context.Context, s2s bool) (net.Conn, error)

Conn dials a connection and returns it without negotiating a session.

func (*Cmd) DialClient added in v0.18.0 

func (cmd *Cmd) DialClient(ctx context.Context, j jid.JID, t *testing.T, features ...xmpp.StreamFeature) (*xmpp.Session, error)

DialClient attempts to connect to the server with a client-to-server (c2s) connection by dialing the address reserved by C2SListen and then negotiating a stream with the location set to the domainpart of j and the origin set to j.

func (*Cmd) DialServer added in v0.18.0 

func (cmd *Cmd) DialServer(ctx context.Context, location, origin jid.JID, t *testing.T, features ...xmpp.StreamFeature) (*xmpp.Session, error)

DialServer attempts to connect to the server with a server-to-server (s2s) connection by dialing the address reserved by S2SListen and then negotiating a stream.

func (*Cmd) Done added in v0.18.0 

func (cmd *Cmd) Done() <-chan error

Done returns a channel that's closed when the commands process terminates.

func (*Cmd) HTTPConn added in v0.18.0 

func (cmd *Cmd) HTTPConn(ctx context.Context, secure bool) (net.Conn, error)

func Log() Option

Log configures the command to copy stdout to the current testing.T. This should not be used for CLI or TUI clients.

func LogFile added in v0.18.0 

func LogFile(f string, tee io.Writer) Option

LogFile reads the provided file into the log in the same way that the Log option reads a commands standard output. It can optionally copy the command to the provided io.Writer (if non-nil) as well similar to the tee(1) command. Normally this should be used by the various server and client packages to read a FIFO which has been configured to be the log by the actual client process so that it functions similar to the tail(1) command.

LogXML configures the command to log sent and received XML to the current testing.T.

func Shutdown 

func Shutdown(f func(*Cmd) error) Option

Shutdown is run before the configuration is removed and is meant to gracefully shutdown the application in case it does not handle the kill signal correctly. If multiple shutdown options are used the functions will be run in the order in which they are passed until an error is encountered.

func TempFile 

func TempFile(cfgFileName string, f func(*Cmd, io.Writer) error) Option

TempFile creates a file in the commands temporary working directory. After all configuration is complete it then calls f to populate the config files.

type SubtestRunner func(func(context.Context, *testing.T, *Cmd)) bool

SubtestRunner is the signature of a function that can be used to start subtests.

func Test 

func Test(ctx context.Context, name string, t *testing.T, opts ...Option) SubtestRunner
