The Test Result Trend widget displays a trend chart of the test results over successive builds for a selected Jenkins job. It shows the number of passed and failed tests evolving over time, making it easy to verify that your test suite is growing alongside your codebase.

Installation note
This widget is available on both Project dashboards and Personal dashboards.
It requires the Hudson/Jenkins plugin to be installed and activated by the platform administrator, and at least one Jenkins job to be registered in the project's Continuous Integration service.
Configuration
When adding the widget, you must specify the following parameter:
Monitored job: select the Jenkins job whose test trend you want to display. The drop-down lists all Jenkins jobs registered in the project's Continuous Integration service. If the list is empty, register at least one job first.
Content
Once a job is selected, the widget displays a trend chart generated directly by Jenkins. The chart plots the number of passed and failed tests across builds over time, making it possible to spot regressions or confirm that test coverage is growing with each commit.
Warning
If the job has never produced test results, the widget displays No test found for this job. Make sure your Jenkins job is configured to execute tests and publish the results (e.g. using the Publish JUnit test result report post-build action). The trend chart only becomes meaningful after several builds have run.
Tip
The trend chart is rendered by Jenkins and fetched in real time. The number of tests displayed typically grows as the number of builds and commits increases. To see the snapshot results of a single build, use the Test Results widget instead.
Edit the monitored job
You can change the monitored job at any time.
Click the gear icon in the widget header, then select Edit.
In the Edit widget dialog, use the Monitored job drop-down to select a different job.
