DAP automated testing docs

The automated tests for the DAP code are implemented using cucumber-js and puppeteer.

By default the tests use the local version of the DAP javascript files. Loading the code into a test HTML page, performing various user actions, and testing the behavior of the code in response to the user actions.

Use the DAP_ENV environment variable to insert live versions of the code into the test HTML page instead of the local version as described below.
