 ## Running tests
 
-### On the command line
+This project has two types of tests
+
+1. unit tests. These are run with
+   [busted](https://github.com/lunarmodules/busted), a lua headless unit testing
+   framework.
+   - very fast to run
+   - can make assertions about lua level results
+   - more difficult to test high level features such as actual integration with
+     yazi
+2. integration tests. These are run with [cypress](https://www.cypress.io/), an
+   interactive JavaScript browser testing framework.
+   - very visual
+   - slower to run but still very nice
+   - can make assertions about the actual UI and integration with yazi
+   - (optionally) can be run to drive the development of new features - this is
+     explained in depth in the
+     [philosophy of cypress](https://www.cypress.io/how-it-works)
