background
There's a lot of awesome assertions libraries out there with a lot of awesome assertion functions. But the reality is that I have struggled to remember all the names of the assertion functions. Is it t.eq
or t.is
? Is it deepStrictEqual
or strictDeepEqual
? I needed a simpler, more memorable testing inteface, so I built Flug.
Flug exposes only one assertion function eq
, which does deep equality checking. This solves 99.9% of my use cases, so that's good enough.
limitations
- not designed for large libraries with hundreds of tests
