processSpec :: CreateProcess -> TestDefM outers (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle) result -> TestDefM outers () result

Run a given process while a test is running and give access to a process handle as an inner resource.

See processSetupFunc.

outerProcessSpec :: CreateProcess -> TestDefM ((Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle) ': outers) inner result -> TestDefM outers inner result

Run a given process while a group of tests is running and give access to a process handle as an outer resource.

See processSetupFunc.

FOOTGUN

The process will be shared accross multiple tests. This may well be a good idea because starting the process can be prohibitively expensive to do around every test. However, sharing the process means that tests could be sharing state. When using this function, it is important to implement some form of cleaning the state before every test. It is also important to use sequential if some such state is maintained (and cleaned) so that the state is not cleaned while another test is running.

processSetupFunc :: CreateProcess -> SetupFunc (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

Set up a process beforehand and stop it afterwards.

The process will be terminated using cleanupProcess.
