How do I run a specific test case within a file?

You can run a specific test by passing the file path followed by the test index, for example: 'lj t test/foo.js 5' runs only the fifth test case in that file.

How does mocking time work in LiteJS?

The 'mock.time()' method freezes the system clock at a specific point, and 'mock.tick(ms)' allows you to manually advance time to trigger setTimeouts or intervals deterministically.

Can I use LiteJS for browser-based UI testing?

Yes, it includes a dedicated 'ui-test.js' extension and the 'lj ui-test' command to run tests in headless Chrome with assertions for navigation, DOM state, and CSS usage.

What makes the LiteJS testing framework unique?

LiteJS is a zero-dependency, ES5-compatible framework that runs natively in both Node.js and browsers, providing advanced features like time-mocking and snapshots without the overhead of larger frameworks.

Does LiteJS support TAP output?

Yes, LiteJS can produce Test Anything Protocol (TAP) compliant output by using the '--tap' flag, making it easy to integrate with various CI/CD reporters.
