 ### Environment variables affecting the build
 The following environment variables affect how the tests are run in both the CI and a local machine.
 
+- `SKIP_SCENARIOS`: Set this environment variable to `false` if it's needed to include the scenarios annotated as `@skip` in the current test execution. Default value: `true`.
 - `BEATS_USE_CI_SNAPSHOTS`: Set this environment variable to `true` if it's needed to use the binary snapshots produced by Beats CI instead of the official releases. The snapshots will be downloaded from a bucket in Google Cloud Storage. Default: `false`. This variable is used by the Beats repository, when testing the artifacts generated by the packaging job.
 - `LOG_LEVEL`: Set this environment variable to `TRACE`, `DEBUG`, `INFO`, `WARN`, `ERROR` or `FATAL` to set the log level in the project. Default: `INFO`.
 - `DEVELOPER_MODE`: Set this environment variable to `true` to activate developer mode, which means not destroying the services provisioned by the test framework. Default: `false`.
