Test-Driven Drupal re-launched as an eBook

The "Test-Driven Drupal" project has been re-launched as a "perpetually published" eBook, based on my previous Automated Testing in Drupal email course (ATDC).

It is still free and can be viewed at https://www.oliverdavies.uk/books/test-driven-drupal and downloaded as a PDF or EPUB.

As I work on it, it will evolve from the email course content into a more detailed version, including new topics such as testing existing Drupal websites with Drupal Test Traits that I couldn't fit into the email course version.
