The behat tests have been disabled while moving GW from SF4 => 6. The test setup was updated to be able to run the behat tests in smoketest mode on the DevConf test container. But this has not yet been fully integrated into the CI/CD test run. Most of the tests seem to work, but some chores remain to be addressed.

Some things that I noticed right away:

• The SAML message rendering seems to be broken (xml parsing results in namespace issues) Warning: DOMDocument::loadXML(): Entity \'mdash\' not defined in Entity
• The SMS test double does not seem to function (or is not loaded?)
