# Testing with feature flags
To run a specific test with a feature flag enabled you can use the `QA::Runtime::Feature` class to enabled and disable feature flags ([via the API](../../../api/features.md)).
Note that administrator authorization is required to change feature flags. `QA::Runtime::Feature` will automatically authenticate as an administrator as long as you provide an appropriate access token via `GITLAB_QA_ADMIN_ACCESS_TOKEN` (recommended), or provide `GITLAB_ADMIN_USERNAME` and `GITLAB_ADMIN_PASSWORD`.
```ruby
context "with feature flag enabled" do
before do
Runtime::Feature.enable('feature_flag_name')
end
it "feature flag test" do
# Execute a test with a feature flag enabled
end
after do
Runtime::Feature.disable('feature_flag_name')
end
end
```
## Running a scenario with a feature flag enabled
It's also possible to run an entire scenario with a feature flag enabled, without having to edit existing tests or write new ones.
Please see the [QA readme](https://gitlab.com/gitlab-org/gitlab/tree/master/qa#running-tests-with-a-feature-flag-enabled) for details.
