Atlassian provides this tutorial for running wired tests with the plugin console, but how do you even get to the plugin console??!? I’m trying to develop a plugin with Jira Server 7.7.1. Is this article valid anymore???
You can, but you should not use the stuff from Atlassian documentation. It is probably best to watch this: https://www.atlassian.com/atlascamp/watch-sessions/advanced-atlassian-development/rule-your-tests-with-arquillian. They also have an example plugin here: https://bitbucket.org/Adaptavist/arquillian-examples/src/master/.
You can probably also reach out to the Adaptavist development team if you need more help, or go meet them at Summit
To expand a little, wired tests just don’t work when your use goes beyond simplistic, so just save yourself some time and go with the framework Remie suggested. The Arquillian test framework was a game-changer for us last year, from zero to comprehensive build-time integration testing over the course of a year. You won’t regret it!
