 OK (608 tests, 861 assertions)


 Issue(s):
 - The file "index.xml" could not be found: Could not find any "index.xml" file in "/srv/phel-lang/data/infection/infection"

I got the following error:

The file "index.xml" could not be found: Could not find any "index.xml" file in 
"/srv/phel-lang/data/infection/infection"

I have been trying to find this issue but the only one seems related is this one: #30
But it's too old and I think it's not exactly the same issue.

You can take a look at the project if you want, there you are everything.

Do you have any clue about this? 😄

Looking at the warning you get from phpunit:

Warning:       XDEBUG_MODE=coverage or xdebug.mode=coverage has to be set

I think this may be xdebug 3.0 , and it hasn't been configured properly for generating coverage.

Do you get a coverage report when running the following command: vendor/bin/phpunit --coverage-text ?

[JesusValera]

I missed adding the flag XDEBUG_MODE=coverage when running vendor/bin/infection.

Thank you a lot @BackEndTea ! 🎉

EDIT: To make it clear. Just run in the terminal

XDEBUG_MODE=coverage ./vendor/bin/infection

Should be fixed in #1510

Released as 0.22.1

Is there a reason we can't inject XDEBUG_MODE before running PHPUnit?

If there's none, this is not resolved.
