…a34eb9cf8d9329 :: assert.contains() !== node::assert.deepEqual() so we have to be more precise and **exactly** specify the returned results, **including** the precise order in which those are added to the returned arrays. Tests have been augmented to first check returned number of elements before checking the exact values via assert.deepEqual() to simplify debugging/diagnostics when a test fails. Following this work, many many tests are stricter than before.
