Bazel rules for vitest

Runs tests with the https://vitest.dev/ test runner under Bazel.

rules_vitest is forked from rules_jest by https://aspect.dev

From the release you wish to use: https://github.com/fremtind/rules_vitest/releases copy the WORKSPACE snippet into your WORKSPACE file.

Run all Vitest tests in the workspace: bazel test --test_lang_filters=vitest //...

See vitest_test API documentation and the example usages in the example folder.

Note that the example also relies on code in the /WORKSPACE file in the root of this repo.

⚠️ vite, vitest, react (optional), jsdom (optional) must be installed at root ⚠️ We have not figured out why yet, but it seems to be an issue with ESM imports under Bazel
