If you follow my work you probably know that I value fast feedback cycles. Most of the open-source I maintain was developed to enable faster feedback cycles. This is why lein-test-refresh and lein-autoexpect were originally created.
Leiningen supports test selectors and lein-test-refresh does as well. This lets you start-up a testing session and only run tests or namespaces with certain metadata on them. This is a super useful feature as it lets you narrow your testing scope to one (or a handful) of tests while working on solving a specific problem.
lein-test-refresh now has built-in functionality that allows you to focus your test scope without restarting the Leiningen test process. If lein-test-refresh sees a
ns form marked with
:test-refresh/focus true in its metadata, then it will only run tests marked with
Below is an example of what this looks like.
This functionality has only been available for a short period of time and I’ve already found it useful. I think you will too. Enjoy.
