Name
test-js - run the LibJS test suite
Synopsis
$ test-js [options...] [path]
Description
test-js runs the LibJS test suite located in /home/anon/Test/js-tests. These
tests are using a custom JavaScript testing framework inspired by
Jest (see test-common.js).
It also supports the test262 parser tests.
The test root directory is assumed to be /home/anon/Tests/js-tests, or $SERENITY_SOURCE_DIR/Userland/Libraries/LibJS/Tests
when using the Lagom build. Optionally you can pass a custom path to test-js to override these defaults.
You can disable output from dbgln() calls by setting the DISABLE_DBG_OUTPUT environment variable.
Options
-t,--show-time: Show duration of each test-g,--collect-often: Collect garbage after every allocation--test262-parser-tests: Run test262 parser tests
Examples
A very simple test looks like this:
describe("Examples from Gary Bernhardt's 'Wat' talk", () => {
test("Na na na na na na na na na na na na na na na na Batman!", () => {
expect(Array(16).join("wat" - 1) + " Batman!").toBe(
"NaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaNNaN Batman!"
);
});
});
