 [Another suite](https://app.ghostinspector.com/suites/5d9603f1af31210914da04ca) of Ghost Inspector tests runs once daily against the Staging site. Status: https://api.ghostinspector.com/v1/suites/5d9603f1af31210914da04ca/status-badge
 
+## Testing philosophy
+
+The tests have been created to traverse the most common user flows in AT-AT. There are a few tests (e.g. "New Portfolio - no optional fields")
+that check for regressions. Others (e.g. "Remove Portfolio Member") check less-common, "negative path" flows. Tests are added as necessary
+to ensure fairly thorough checking of AT-AT.
+
+The tests are constructed in a "stepwise" fashion; that is, no individual test depends upon another, and each test checks one step in complex
+user flows. As an example, there are six tests for creating a new Task Order, one corresponding to each screen in the process plus one
+for adding a second CLIN to a TO. These tests rely on Ghost Inspector's "Import steps from Test X" functionality to perform all the
+necessary setup for the current test. This also ensures that tests can be run in any sequence because Ghost Inspector launches up to four
+tests simultaneously.

 ## Running Ghost Inspector tests locally
 
 To run the Ghost Inspector tests against a local instance of AT-AT,
