phpunit deprecation notices only displayed when defining source directory

[wickedOne]

Q	A
PHPUnit version	9.5.25
PHP version	7.4.24
Installation Method	Composer

Summary

when running phpunit without defining a source directory at the end of your command it does not display phpunit's (deprecation) warnings

Current behavior

this does not display phpunit's (deprecation) warnings

vendor/bin/phpunit --testsuite=Foo

while this does (e.g. Warning: Test case class not matching filename is deprecated)

vendor/bin/phpunit --testsuite=Foo tests/

How to reproduce

minimal, self-contained test case to reproduce can be found over here

Expected behavior

i'm not quite sure what is to be expected (i.e. is this expected behaviour or a bug). personally i'd expect the (deprecation) warnings to be shown regardless or perhaps have a flag to have them displayed

Can you reproduce the issue with PHPUnit 9.5.25?

Nevermind, your composer.lock file says 9.5.25 (not 9.5.20 like your ticket).

[wickedOne]

sorry for that, updated the ticket for completeness

[sebastianbergmann]

I can confirm that this problem still exists in PHPUnit 9.5.28.

Not sure its as easy as this but I also came across this issue and guessing they have the same origin one possible solution is to add the warnings from the suite to the result from the TestSuiteMapper map() function i.e.

// TextUI\TestSuiteMapper:89
...
if (!$testSuiteEmpty) {
    $result->addTest($testSuite);
    foreach ($testSuite->warnings() as $warning) {
        $result->addWarning($warning);
    }
}
...

I am sorry for not getting to this before the end of bugfix support for PHPUnit 9.
