Running tests

Usually you'll run:

• npm run test -- [test suite] --filter="..."

where test suite is any of:

• brave_components_unittests (C++ unit tests in brave/components)
• brave_unit_tests (C++ unit tests anywhere else in brave/)
• brave_browser_tests
• chromium_unit_tests (Chromium C++ unit tests in src/)
• browser_tests (Chromium browser tests in src/)

and --filter is the full name of the test (FixtureName.TestName) but you can use wildcards and combine filters with : e.g. --filter="*Foo*:*Bar*"

See chromium's docs/testing_in_chromium.md.

Javascript / Typescript unit tests

Isolated *.test.ts(x) tests are run via:

• npm run test-unit -- [path blob filter]
