-## Created with Minicli
+## Tests
+To keep dependencies to a minimum, the `minicli/application` template repository doesn't require any specific testing framework, but we highly recommend using [PestPHP](https://pestphp.com), which is the testing framework used by [minicli/minicli](https://github.com/minicli/minicli).
+
+### Bootstrapping Tests with PestPHP
+
+To get started with PestPHP to test your Minicli application, first include the required dependencies with:
+
+```bash
+composer require pestphp/pest --dev --with-all-dependencies
+```
+
+Then, run the following command to create a tests folder and a couple example tests:
+
+```bash
+./vendor/bin/pest --init
+```
+
+Then you can use the following command to run the test suite:
+
+```bash
+./vendor/bin/pest
+```
