Test Runner

Jest like test runner for JavaScript code that runs in the browser. No installation needed.

Usage

Create a test file, import the TT test runner from test-runner.js.

Add tests with

TT.it('Test description', () => { ... });

Add specs with

TT.spec('Spec tests', (tt) => { ... }

Add tests to the specs function with

TT.spec('Spec tests', (tt) => {
  tt.it('Test description', () => { ... });
});

Check test results with

TT.expect(result).toBe("exact value");
TT.expect(result).greaterThan(0);
TT.expect(result).lowerThan(9999);
TT.expect(result).isString();

More comparisons can be added to the test-runner expect function if needed.

Skip specs and tests with

TT.skip.it( ...
TT.skip.spec( ...

Execute only these tests with

TT.only.it( ...
TT.only.spec( ...

Run the tests in the main html file, loading the helper file with

<script type="module" src="../test-runner-init.js"></script>

And finally open the console to see the tests running there.
