 The ``ci.json`` file is used to specify how the test suite and sketches will handled by the CI system. It can contain the following fields:
 
-* ``targets``: A dictionary that specifies the supported targets. The key is the target name and the value is a boolean that specifies if the
-  target is supported. By default, all targets are assumed to be supported. This field is also valid for examples.
+* ``requires``: A list of configurations in ``sdkconfig`` that are required to run the test suite. The test suite will only run on the targets
+  that have the required configurations. By default, no configurations are required.
+* ``targets``: A dictionary that specifies the targets for which the tests will be run. The key is the target name and the value is a boolean
+  that specifies if the test should be run for that target. By default, all targets are enabled as long as they have the required configurations
+  specified in the ``requires`` field. This field is also valid for examples.
 * ``platforms``: A dictionary that specifies the supported platforms. The key is the platform name and the value is a boolean that specifies if
   the platform is supported. By default, all platforms are assumed to be supported.
 * ``extra_tags``: A list of extra tags that the runner will require when running the test suite in hardware. By default, no extra tags are required.
