I'm debugging why my given memory limit is not being applied in the adapter.

Would you be able to write a small integration test using ini_set() and @runInSeparateProcess, perhaps?

I will try to find some time the next days to write some tests.

There are no tests whatsoever for options object.
@leuchtdiode It would be great if you introduce them.

For this problem ini_set/ini_get is not needed. Test that:

• call to setMemoryLimit() with invalid value like 'M128' produces exception with message containing "Invalid memory limit".
• call to setMemoryLimit() actually sets it.

I just created a pull request, but there are some issues with my formatting. Do you have a code style XML somewhere for PHPStorm which I can use?

Furthermore I added these tests:

[ 'M256', 256 ] [ 'G1024', 1024 ]

as valid ones. In my opinion they should raise an InvalidArgumentException as well. What do you think? Which values do we want to allow? Only integers and "G", "M" and "k" as suffix, right? If so, I could adapt the regex and the tests.

Also I added to return "null" when "null" is given to normalize, because it broke the already existing test testOptionsFluentInterface from the common base test class.

There's a PHPCS configuration at the root of the repository:

Worth discussing on the PR directly :)
