No function for comparing arrays and ignoring order

Gotcha. We would probably just gather and sort the results before doing a should.Resemble assertion. For now, we don't see a need to add this kind of assertion to the package, but thanks for checking in first.

Did you know that you can implement your own custom assertions? Suppose you implemented a function with a very specific signature:

package yourpackage

func ShouldEqualUnordered(actual interface{}, expected ...interface{}) string {
    // your implementation here...
}

Then you can use your custom assertion in a So call:

So(collectionA, yourpackage.ShouldEqualUnordered, collectionB)

I'm happy to build this myself, but hoping to get approval from a team member before I get started. Lmk!

It has always seemed to me that ordering is a fundamental characteristic of slices and arrays, so an assertion on slices or arrays should require that elements be in a consistent order. Will you please provide examples or code snippets that illustrate your use case more fully?

any code that involves concurrency may append results to an array in different orders each time
