I like the convenience of using the Jenkins plug-in for running our tests as (scheduled) Jenkins tasks. My team would like to be able to see the results of these test runs in Slack and that integration offers the nice summary as well as a link to the complete report.
But if I want the nice Slack integration I need to set up the test runner in Jenkins. While that is doable, it would be somewhat easier to use the plugin.
