-     * Here we're checking that enabling inference in IDE doesn't affect compilation via JPS

-     * the following two tests are connected:
-     * - testKotlinProjectWithEnabledNewInferenceInIDE checks that project is compiled when new inference is enabled only in IDE
-     *   - this is done via project component
-     * - testKotlinProjectWithErrorsBecauseOfNewInference checks that project isn't compiled when new inference is enabled in the compiler
-     *
-     * So, if the former will fail => option affects JPS compilation, it's bad. Also, if the latter test fails => test is useless as it's
-     * compiled with new and old inference.
