[m1kola]

To do:

• Handle this from Part 2: Reduce number of variable sources. Bundle variables. #498.
• Handle this from 🌱 Part 4: Reduce number of variable sources. Required packages #500
• Handle this from 🌱 Part 5: Reduce number of variable sources. Final cleanup #501
• Update assertions like this with go-cmp in variablesources/installed_package_test.go.

Description

Experiment to make testing a bit easier.

This is not the best example, but I'm trying to find a nicier way to do these comparisons.

E.g. in #498 we do this:

gocmpopts:= []cmp.Option{
cmpopts.IgnoreUnexported(sync.RWMutex{}),
cmp.AllowUnexported(
sync.RWMutex{},
olmvariables.BundleVariable{},
input.SimpleVariable{},
constraint.DependencyConstraint{},
catalogmetadata.Bundle{},
),
cmpopts.IgnoreFields(
// Do not compare a func field
catalogmetadata.PackageRequired{}, "SemverRange",
),
}
require.Empty(t, cmp.Diff(bundles, expectedVariables, gocmpopts...))

Haven't had enough time to review all of it - but you likely do not want to compare internals of sync.RWMutex - perhaps even of the others. For each, ask if it's possible or valid for the third-party package to change the implementation detail of unexported fields and if that would be a bona-fide concern for the caller here.
