module StubFeatureFlags
  # Stub Feature flags with `flag_name: true/false`
  #
  # @param [Hash] features where key is feature name and value is boolean whether enabled or not.
  #               Alternatively, you can specify Hash to enable the flag on a specific thing.
  #
  # Examples
  # - `stub_feature_flags(ci_live_trace: false)` ... Disable `ci_live_trace`
  #   feature flag globally.
  # - `stub_feature_flags(ci_live_trace: project)` ...
  # - `stub_feature_flags(ci_live_trace: [project1, project2])` ...
  #   Enable `ci_live_trace` feature flag only on the specified projects.
