+## Q: How do I get a test result back from CI?
+
+You have a failing test and you want to analyse the output. Here is how you can do it:
+
+* First step is to check information available on the CDash report (link should be available at the end of the job logs).
+* If this is not enough to investigate, you can download the test output:
+    * Find the file name of the test output (let say `myOutput.tif`)
+    * Edit the file `.gitlab-ci.yml` and locate the job where your test fails
+    * In the job description, add this section
+```
+  artifacts:
+    when: always
+    expire_in: 24 hrs
+    paths:
+      - build/Testing/Temporary/myOutput.tif
+```
+
+Then commit this change, and when the job completes (still failing), you can browse the artifacts and download the file you need.
