Hey guys, is there any built-in way to assert equality of doubles/floats in Kotlin tests?
I'm especially interested in the JVM platform, but if there are some multiplatform ways from kotlin-test I'd be happy to learn about them.

Other than .equals() ?

[Joffrey]

AFAIK, equals doesn't account for the imprecision of floating point values, does it? At least, assertEquals() fails for my current values because of rounding/truncation errors.

junits assertEquals()? https://stackoverflow.com/questions/33274030/why-is-assertequalsdouble-double-deprecated-in-junit/33274179#33274179 assertEquals(double, double, double)

[Joffrey]

Yes, I could directly use this one, indeed. I just hoped there was an equivalent in kotlin.test 😞

[spand]

The assertions on kotlin seems quite bare but there is nothing wrong with using your own.

[Joffrey]

I think I'll just go with the Junit one for now, since I'm using junit anyway under the hood

[Wesley Acheson]

I've been using AssertJ which is probably no help to you

[Joffrey]

Indeed. I mean, as long as I already have JUnit and its assertions, there is no point for me to add any other library for now. I'd rather keep my dependencies small.
