Class not found (custom autoloader)

[mrodikov]

Q	A
PHPUnit version	9.3.8
PHPCov version	8.1.0
PHP version	7.3.11, 7.4.7
Installation Method	Composer

(PHAR doesn't work for me with the above PHPUnit & PHPCov versions, coverage file produced by PHPUnit is loaded as "Incomplete" class in PHPCov)

Summary

When using a custom class loader and processUncoveredFiles="true", an error occurs in PHPCov due to inability to find the class.

Current behavior

Generating code coverage report in HTML format ...
[Uncaught Error in /path/to/phpcov-issue-demo/lib/MyPreciousLib/Seasonings/TikkaMassala.php on line 3]
Error: Class 'BaseSeasonings_Curry' not found in /path/to/phpcov-issue-demo/lib/MyPreciousLib/Seasonings/TikkaMassala.php:3

How to reproduce

1. Clone demo project https://github.com/mrodikov/phpcov-issue-demo

2. phpdbg -qrr /path/to/any/phpunit/bin/phpunit -c /path/to/phpcov-issue-demo/lib/MyPreciousLib/phpunit.xml --coverage-php /path/to/phpcov-issue-demo/var/coverage.cov

3. phpdbg -qrr /path/to/any/phpcov/bin/phpcov  merge --html /path/to/html/report/ /path/to/phpcov-issue-demo/var/

Expected behavior

HTML coverage report generated

Notes

The problem is that the custom autoloader is used, which can load Path_To_My_Real_Class classes from Path/To/My/Real/Class.php (obviously, the includePath option will not work here). PHPUnit uses a custom autoloader since I explicitly included it in bootstrap.php. PHPCov knows nothing about phpunit.xml or bootstrap.php, so it cannot find the class.

It's been more than a year and still no feedback on this one. I have exactly same issue, but for me it may not happen for some tests I get coverage report for. I've been trying to understand the difference between the OK and failing coverages but still no luck.

[lex0r]

I managed to identify a more specific context for the error, when using phpcov's merge command. It seems the error is not related with the fact a "custom" autoloader is used, since I use the default composer's one.

Basically, if a file with a class is completely uncovered and when CodeCoverage::processUncoveredFilesFromFilter() takes care of including these, it just does include_once on the file. If a class defined in the file uses a trait, the trait inclusion will fail leading to "Fatal error: Trait 'Foo\Bar' not found in ...".

This might be caused by the fact that phpcov relies on its own spl_autoload_register() handler which has no knowledge of the user code base. When a trait is included by a class with "use Bar;" obviously it can't be found among the classes known to phpcov's autoloader.

@sebastianbergmann FYI

Had a similar experience. In my case I took a shortcut: added phpcov as a composer --dev dependency and afterwards all namespaces were resolved correctly.

@llupa how did you add it through Composer?

[llupa]

@swarrenwecareconnectorg regular composer require --dev phpunit/phpcov and then call it via vendor/bin/phpcov merge [options and arguments]

Any update on this one? I have the same issue with the not found file.
