Wallaby’s new Smart Start feature allows you to quickly start Wallaby and only the test file(s) that you are currently working on will be executed. As soon as you open another test file, Wallaby will automatically run those tests and Wallaby will continue to execute those tests when they are affected by your code changes. Smart Start can be configured to always run a set of test files on start, and you can customize the automatic test execution behavior to run on edit (instead of open), or to never run automatically.
Using Smart Start is usually many times faster than running all tests within your project. For larger projects and times when you are working on a specific component within your project, this new feature enables a highly productive workflow.
