Node.js Debugging support implemented as part of https://issues.jboss.org/browse/JBIDE-22225
Should be covered with red deer integration tests. Basically, test coverage of Node.js Debugger facilities already covered with red deer in JSDT project - https://git.eclipse.org/r/#/c/82836/
However, implementing smth. similar for OpenShift will be much trickier. Basically, there is an integration test org.jboss.tools.openshift.ui.bot.test.application.v3.adapter.PublishChangesTest which is used for server adapter publishing. For now this test is not sustainable due to https://issues.jboss.org/browse/JBIDE-23005 .
