+### The `detect-tests` CI job
+
+Most CI/CD pipelines for `gitlab-org/gitlab` will run a [`detect-tests` CI job](https://gitlab.com/gitlab-org/gitlab/-/blob/0c6058def8f182b4a2410db5d08a9550b951b2d8/.gitlab/ci/setup.gitlab-ci.yml#L101-146) in the `prepare` stage to detect which backend/frontend tests should be run based on the files that changed in the given MR.
+
+The `detect-tests` job will create many files that will contain the backend/frontend tests that should be run. Those files will be read in subsequent jobs in the pipeline, and only those tests will be executed.

### RSpec predictive jobs
#### Determining predictive RSpec test files in a merge request
-To identify the RSpec tests that are likely to fail in a merge request, we use the [`test_file_finder` gem](https://gitlab.com/gitlab-org/ci-cd/test_file_finder), with two strategies:
+To identify the RSpec tests that are likely to fail in a merge request, we use *static mappings* and *dynamic mappings*.

The test mappings contain a map of each source files to a list of test files which is dependent of the source file.
-In the `detect-tests` job, we use this mapping to identify the predictive tests needed for the current merge request.
+##### Dynamic mappings
+
+First, we use the [`test_file_finder` gem](https://gitlab.com/gitlab-org/ci-cd/test_file_finder), with a dynamic mapping strategy from test coverage tracing (generated via the [`Crystalball` gem](https://github.com/toptal/crystalball))

+## Merge Trains
+
+### Why do we need to have a “stable” master branch to enable merge trains?
+
+If the master branch is unstable (i.e. CI/CD pipelines for the master branch are failing frequently), all of the merge requests pipelines that were added AFTER a faulty merge request pipeline would have to be **cancelled** and **added back to the train**, which would create a lot of delays if the merge train is long.
+
+### How stable does the master branch have to be for us to enable merge trains?
+
+We don't have a specific number, but we need to have better numbers for flaky tests failures and infrastructure failures (see the [Master Broken Incidents RCA Dashboard](https://app.periscopedata.com/app/gitlab/1082465/Master-Broken-Incidents-Root-Cause-Analysis)).
+
+### Could we gradually move to merge trains in our CI/CD configuration?
