Console::stdOut and testing about yii-console HOT 10 CLOSED

Well I've considered (not very thoroughly) some options:

1. Non-static helper

• Change Console to be a normal class that takes the streams as constructor argument
• Add Console::__callStatic to support static calls that default to a singleton instance.
  (I think this is similiar to Laravel Facades)

2. Static configuration of streams

• Add public static $stdout = \STDOUT; which is overridable.

3. Switch to echo (but this does not solve the issue for STDERR).

Do you have an idea on how to fix it?

Or more advanced, haven't tested this myself: https://stackoverflow.com/questions/8348927/is-there-a-way-test-stderr-output-in-phpunit

What's about $I->seeInShellOutput() from Codeception?

Examples: https://github.com/dmstr/phd5-app/blob/master/tests/codeception/cli/1-YiiCept.php

It doesn't work since it can't intercept fwrite commands.

Hmm, I am testing all the output written by $this->stdout() this way?!

Ah wait you're running new shell commands instead of running the test inside the same process.
Basically the approach you use is not about Yii at all, your tests could test any executable by executing it and checking the result.
That is not the same as testing one specific function; it would work though...

@SamMousa Ah yes, you are right. I never got familiar with mocking all the stuff :) But, I remember having issues with STDERR also.

@SamMousa Did you consider "mocking" fwrite in tests, like so https://www.schmengler-se.de/en/2011/03/php-mocking-built-in-functions-like-time-in-unit-tests/

from yii-console.

How about mock/DI replace Console class for tests?
