+[#configure-a-job-running-codeception-tests]
+=== Configure a job running Codeception tests
+
+Codeception doesn't support providing paths to multiple files in a single `codecept run` command execution directly. We can circumvent this by creating a dynamic group. Add the following to your `codeception.yml` file:
+
+[,yml]
+----
+groups:
+    circleci: tests/_output/circleci
+----
+
+In your `.circleci/config.yml` file, we can use `circleci tests glob` to get the Cest files from the path we need. `circleci tests run` will then sift through the Cest files and put the necessary ones into `tests/_output/circleci` file. Before running the tests with the `circleci` group, we ensure the `tests/_output/circleci` file exists. The `--xml` option is required for the rerun tests feature to work. The `--html` option is optional, but useful for easy debugging through artifacts.
