Some helpers for running shadow-cljs tests.

Usage

First, add this to your shadow-cljs.edn:

[org.clojars.lucywang000/shadow-test-utils "0.0.2"]

For deps.edn:

org.clojars.lucywang000/shadow-test-utils {:mvn/version "0.0.2"}

Make sure this is placed before thheller/shadow-cljs.

Restart your shadow-cljs process, and you shall have the tests filtering working.

For the custom browser test reporter to work, modify the preloads of your :browser-test target:

:builds {
  ...

  :test {:target   :browser-test
         :devtools {:preloads [shadow-test-utils.pretty-diff]}}
}

Shadow-cljs Test filtering

This library add kaocha-like tests filtering to shadow-cljs:

• If there are tests that are annotated with ^:focus metadata, then only those tests would be executed. This is useful to only run the test that are relevant to the current piece of code being developed.
• If there are tests that are marked with ^:skip metadata, then these tests would be ignored. This is useful to e.g. not execute flaky tests without comment out the whole test code, which could result in unnecessary huge git diff.

(deftest ^:focus foo-test) is like it.only/test.only in mocha/jest, (deftest ^:skip foo-test ...) is like it.skip/test.skip in mocha/jest

:focus/:skip metadata can also be used at namespace level with similar effects, in which case whole namespace is considered as a whole to be executed or ignored.
