Appendix B. Testing an SPA
This appendix covers
- Setting up test modes
- Selecting a test framework
- Setting up nodeunit
- Creating a test suite
- Adjusting SPA modules for test settings
This appendix builds on code we’ve completed in chapter 8. Before starting, you should have the project files from chapter 8, as we’ll be adding to them. We recommend you copy the entire directory structure you created in chapter 8 into a new “appendix_B” directory and update them there.
We’re fans of test-driven development and have worked gonzo projects where the generation of tests was automated. A permutation tool was used to automatically generate thousands of regression tests by simply describing the APIs and their expected behavior. If a developer modified code, it had to pass the regression tests before it could be checked in to the repository. And when a new API was introduced, the developer added the description to the configuration, and hundreds or thousands of new tests were generated automatically. This practice resulted in exceptional quality, as code coverage was great, and we rarely had a regression of any sort.
