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.

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!"
);
});
});
