Quick and dirty power assertions today!

[bvalyou]

I was jonesing for some better output in my test code and decided to see what I could do with a quick utility

// TestUtils.pkl
function assertEquals(actual, expected): Boolean = actual == expected || throw("assertion failed - expected \(expected) but was \(actual)")

// ApplicationTest.pkl
...
facts {
  ["Application backend should configure a base (unfinished) application"] {
    TestUtils.assertEquals(backend.k8sResources.length, 6)
  }
}

$ pkl test
...
module ApplicationTest
  facts
    ✘ Application backend should configure a base (unfinished) application
       –– Pkl Error ––
       assertion failed - expected 6 but was 5

       1 | function assertEquals(actual, expected): Boolean = actual == expected || throw("assertion failed - expected \(expected) but was \(actual)")
                                                                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
       at TestUtils#assertEquals
       
       24 | TestUtils.assertEquals(backend.k8sResources.length, 6)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...

I'm very pleased with this quality of life improvement - it doesn't clutter the output when the test passes either:

module ApplicationTest
  facts
    ✔ Application backend should configure a base (unfinished) application

Interested to see what others have done in this area!
