please clarify if this problem is also present in runSymfonyConsoleCommand, because when reading it seems to be exclusive of runShellCommand.

I'm not sure if I tried. But the mail assertions are working by looking at the web debug toolbar, aren't they?

I didn't try runSymfonyConsoleCommand(). Is there a way to pipe input to the command?
Right now, I'm doing:

$I->runShellCommand('printf "foobar" | php bin/console app:my_command --env=test');

@ThomasLandauer yes, you can use the third parameter $consoleInputs for that. So the equivalent to the above would be

$I->runSymfonyConsoleCommand('app:my_command', ['--env' => 'test'], ['foobar']);

Hm, then the test executions hangs at this line - looks like the console is waiting for something. I didn't look into it further - are you sure that this works?

@ThomasLandauer I tested it before writing that comment just to be sure, so yes, it does work in general. Maybe we're talking about different things, so I created Codeception/symfony-module-tests#28 to demonstrate what I'm talking about.

The test is a cool idea!
My command doesn't ask questions (i.e. doesn't wait for input), it reads input from STDIN:

$fread = fread(STDIN, $length);

@ThomasLandauer oh, I see. I didn't have such a use case yet, so I don't know, but the console input parameter might indeed not work with STDIN then.

* Codeception will not notice it.
* As a more professional alternative, we recommend Mailpit, which also lets you test the content of the mail.
