How to reference an environment variable in phpunit.xml file?

In my phpunit.xml file, I've got a chunk for logging code coverage reports, something like this:

<logging>
    <log type="coverage-html" target="./logs/coverage" ...
</logging>

I don't like using a hard-coded string for the target path however. I would like each user to be able to specify their target via an environment variable so they can have the logs go wherever they like, without having to change a source-controlled file. I'm looking to do something like this:

<logging>
    <log type="coverage-html" target="$LOG_PATH" ...
</logging>

I don't see any support for this sort of substitution in the PHPUnit docs. Does anyone have an idea for how to accomplish this?

Actually you should not have phpunit.xml in your repository. PHPUnit looks for two XML files on execution, that is phpunit.xml and phpunit.xml.dist. It will always prioritize phpunit.xml if it's found, otherwise it will fallback to phpunit.xml.dist. From the documentation:

If phpunit.xml or phpunit.xml.dist (in that order) exist in the current working directory and --configuration is not used, the configuration will be automatically read from that file.

With that said you should have phpunit.xml.dist in your repository as a template/boilerplate setup for running the tests. Then each individual developer can create their own phpunit.xml from that if they wish to add their specific settings.

Also the file phpunit.xml should be ignored in your repository.

According to Herr Bergman:

protected $backupGlobals = FALSE;

In your test class will disable the (default) behaviour of backing up and restoring global variables. However, do note that putting this in the setUp method will have no effect. Hope that helps.
