ava v1.4.1 Release Notes

Release Date: 2019-03-24 // about 5 years ago

  • Focusing power-assert

    AVA comes with power-assert built-in, giving you more descriptive assertion messages. However it's been confusing to understand which assertions come with power-assert. To address this we've added the new t.assert() assertion. It's now the only assertion that is power-assert enabled. The assertion passes if called with a truthy value. Consider this example:

    test('enhanced assertions', t =\> { const a = /foo/; const b = 'bar'; const c = 'baz'; t.assert(a.test(b) || b === c); });

    AVA will output: 6: const c = 'baz'; ✅ 7: t.assert(a.test(b) || b === c); 8: }); Value is not truthy: false ✅ a.test(b) || b === c => false b === c => false c => 'baz' b => 'bar' ✅ a.test(b) => false b => 'bar' a => /foo/

    ⚡️ Our ESLint plugin has been updated to support this new assertion. Many thanks to @eemed for implementing this! 9406470
