Hi @Bartlomiejsz
Please check the unit tests fail.

[Bartlomiejsz]

@ishakhsuvarov I'm not sure what is wrong here. Running phpunit -c dev\tests\static . locally ends without errors. Also I don't think my changes broke something here. Maybe you should try rerunning travis?

[ishakhsuvarov]

@Bartlomiejsz I've restarted the Travis job, however I am pretty sure issue is going to persist.
You referred to the dev/tests/static however the job for unit tests was failed, try running a whole scope of unit tests.
Sadly, due to error, currently Travis would not show exact tests which were failed, I am working on a fix for this issue.

@ishakhsuvarov I've tried to run a whole scope of tests, and it failed. But it returned me following error:
Fatal error: Class 'Magento\TestFramework\TestCase\WebapiAbstract' not found in ...\dev\tests\api-functional\testsuite\Magento\Analytics\Api\LinkProviderTest.php on line 20

But when I tried to run tests on develop branch, it also failed, returning exactly same error.

@Bartlomiejsz Looks like the unit which fails is
Magento\Email\Test\Unit\Model\Template\FilterTest::testApplyInlineCss
Please check

@okorshenko yes, I would, but unfortunately right now I have some problems with my computer. So any help here would be appreciated
