Jest runs the same tests multiple times, for example :
PASS document plugins/document/scripts/document/store/actions.test.js (11.374 s)
PASS tracker plugins/tracker/scripts/angular-artifact-modal/src/model/field-values-service.test.js (18.202 s)
PASS tracker plugins/tracker/scripts/angular-artifact-modal/src/model/field-values-service.test.js (12.655 s)
PASS tracker plugins/tracker/scripts/angular-artifact-modal/src/model/field-values-service.test.js (9.435 s)
PASS tracker plugins/tracker/scripts/angular-artifact-modal/src/model/field-values-service.test.js (11 s)
This behaviour appeared when we started symlinking plugins. In this case, each "depending" plugin runs Tracker tests again, resulting in 1 expected run and 3 supernumerary runs because AgileDashboard, TestManagement and CrossTracker search plugins all depend on Tracker plugin.
We should fix our configuration to avoid those unintentional runs.
