# Running Tests ```eval_rst .. toctree:: from-web from-local-system custom-runner ``` The simplest way to run the tests is via the public website. More detail on that approach is available in [Running tests from the Web](from-web). Contributors who are interested in modifying and creating tests should refer to [Running Tests from the Local System](from-local-system). Advanced use cases may call for a customized method of executing the tests. Guidelines for writing a custom "runner" are available at [Writing Your Own Runner](custom-runner).
