determinize-prow-jobs invalidates TEST_SKIP

[mjudeikis]

We trying to skip some invalid/broken/not-relevant tests for openshift-azure. But we have failure in determinize-prow-jobs:
https://openshift-gce-devel.appspot.com/build/origin-ci-test/pr-logs/pull/openshift_release/1520/pull-ci-openshift-release-master-ordered-prow-config/544

But if we commit with "determinized" content we get invalid regexp:

.*((The HAProxy router should set Forwarded headers appropriately)|(oc            new-app should succeed with a --name of 58 characters)|(process valueFrom            in build strategy environment variables should successfully resolve valueFrom            in docker build environment variables)|(prune builds based on settings            in the buildconfig should prune failed builds based on the failedBuildsHistoryLimit            setting)|(Prometheus when installed to the cluster should start and expose            a secured proxy and unsecured metrics)|(Prometheus when installed to the            cluster should start and expose a secured proxy and verify build metrics)|(templateservicebroker)|(deploymentconfigs            with multiple image change triggers [Conformance] should run a successful            deployment with multiple triggers)|(templateinstance readiness test should            report failed soon after an annotated objects has failed)|(s2i build with            a root user image should create a root build and pass with a privileged            SCC)).*

Which has a lot of whitespaces and skips are ignored.

...(deploymentconfigs with multiple image change triggers [Conformance] should run a successful deployment with multiple triggers)...

Those brackets probably need to be escaped. In my openshift/release#1341 script, see:

 processed = re.escape(''.join(chars).strip()) processed = processed.replace(r'\ ', ' ').replace(r'\-', '-').replace(r'\/', '/').replace(r'\=', '=') # Work around https://bugs.python.org/issue29995, fixed in Python 3.7

Dunno if that's what's giving you the error message. You could try dropping |(...) blocks until MustCompile accepts it.

@wking you right for the exit of the brackets. But this should invalidate only one test skipping:

But this, this might not be an issue.
