PHPUnit Test not working

by Koray Redoon - Tuesday, November 27, 2018, 6:05 PM

Hello Community

I tried some PHPUnit Tests with Moodle but it isnt working.

When i try to execute my testcase -> "vendor\bin\phpunit mod_myplugin_sample_testcase", i become everytime the answer:

"Moodle 3.5.3+ (Build: 20181123)
Php: 7.1.10, mariadb: 10.1.28, OS: Windows NT 10.0 i586
Moodle PHPUnit environment was initialised for different version, please use:
php admin\tool\phpunit\cli\init.php"

I did this several times... The Tables are dropping and there i see my Plugin as successfully.

I'm seeing this same thing on 3.6.2+ and 3.6.4. Just a plain install of Moodle produces this error:

Moodle 3.6.2+ (Build: 20190307)
Php: 7.2.15, mysqli: 5.7.26, OS: Linux 3.10.0-957.12.2.el7.x86_64 x86_64
Moodle PHPUnit environment was initialised for different version, please use:
php admin/tool/phpunit/cli/init.php

I submitted a tracker issue but they closed as not a bug. Anyone else have this experience? PHPUnit runs on this same server with a 3.4 installation.

This happens if you have multiple php versions installed: compare the output of php -v (client) with the output of the Moodle page admin/phpinfo.php.

Thanks for the suggestion Renaat, but I only have one version of PHP installed, and it displays correctly via php -v and on the Moodle page.

When I look at what generates this error, it appears to be if the database and moodledata were not created with the same version of Moodle you are trying to run the unit tests from. However, I get the error on a totally fresh install of 3.6, where the database and data are most definitely created by that version of Moodle. The same server runs the unit tests in a 3.4 installation just fine.

When I run the init.php script, nothing is put into the /moodledata/phpunit directory, which is where the library looks to do the comparison to run the unit tests. I'm wondering if there isn't an issue with the init script in 3.6 (and sounds like 3.5 for Koray above). I submitted a tracker issue, but was told it is not a bug

Compare your different Moodle configuration files and make sure they do not overlap: different wwwroot - dataroot - dbname - tempdir - cachedir - localcachedir - phpunit_prefix - phpunit_dataroot.

All the Moodle instances were using different configs. I discovered the problem by running php admin/tool/phpunit/cli/util.php --install and was able to see the initialization process was being killed because php was out of memory. After allocating more memory to my VM, I am finally able to run the phpunit tests on the 3.6 installation now!

Thank you for your feedback - the help is most appreciated!
