 * `files` – A list of test files or directories with test files. This can be a string if you want to specify just one file or directory. Also, you can use
 masks for this property.
 
+* `ignoreFiles` - A list of paths or masks to ignore from reading while test finding. When you write `!**/some-dir/**` it means that the directory will be read, but all the entries will not be included in the results. So using `ignoreFiles` you can speed up test reading for your project.

 * `browsers` – A list of browser IDs to run the tests specified in `files`. All browsers by default.
 
 You can specify sets to run using the CLI option `--set`.
