The Exit matcher operates on a session:
|
|
|
|
Expect(session).Should(Exit(<optional status code>))
|
|
|
|
Exit passes if the session has already exited.
|
|
|
|
If no status code is provided, then Exit will succeed if the session has exited regardless of exit code.
|
|
Otherwise, Exit will only succeed if the process has exited with the provided status code.
|
|
|
|
Note that the process must have already exited. To wait for a process to exit, use Eventually:
|
|
|
|
Eventually(session, 3).Should(Exit(0))
