Description
There are currently 8 places in the source code which check whether the global PHP_CODESNIFFER_IN_TESTS constant is defined and if so, change some behaviour.
Code behaving differently in test vs production situations makes the code risky to begin with.
It also makes it exponentially harder to write tests for some parts of the codebase and wastes a lot of dev time when devs are scratching their heads about tests not working, while all the while, the test is perfectly fine, but somewhere in the path to the code under test, the behaviour of PHPCS was changed via one of those PHP_CODESNIFFER_IN_TESTS checks.....
It should be investigated for each of the uses of PHP_CODESNIFFER_IN_TESTS in src, whether it can be removed and/or if there is a different solution possible to the problem the condition was trying to solve.
Ideally, the PHP_CODESNIFFER_IN_TESTS constant should be removed at the end of this exercise (but that's not strictly the goal of this ticket).
At the time of writing the following code refers to the constant
