According to Sebastian Bergmann: "That configuration setting has not had an effect in years. It was removed long ago".

To convert existing tests to use the base class use

 perl -p -i -e 's/PHPUnit_Framework_TestCase/SimpleSAML\\Test\\Utils\\ClearStateTestCase/g' `grep -rl PHPUnit_Framework_TestCase tests | grep -v ClearStateTestCase.php`

A PHPUnit listener unsets SSP environmental variables and attempts
to restore globals.

Try to make it build with the saml module included by using the phpunit version we are requiring instead of the one preinstalled.

* One test suite for all tests.
* One file per class that is tested.

These changes should make it easier to add new tests.

Updated the composer.lock to install satooshi/php-coveralls

Add .coveralls.yml to stop errors.

Added coverage_clover pointing to correct location.

json_path now... anything to get bin/vendor/coveralls to actually execute!

Only push coverage reports for a single version of PHP

Add whitelist + exclusion files to coverage.

Reduce code coverage % by processing all files :-)

Beware adding additional directories for tests without setting up config + mocking the rest of the environment.

Don't show uncovered files.

Attempt upload for all PHP versions. Is this stacktrace always generated?

Return to "true" for uncovered files.

There is a path problem somewhere!
