I think you misunderstood me, make test does not, or rather will not succeed because it does not take into account cross-package. It will still do what it needs to in related to what it needs to check.
As you can see in your error log, it fails exactly on one of the items listed as said to fail API4.
The current coverage is at 47.45% and you can see that on the listed link on my previous answer.
If you need to further test something specific, you have that step that allows you to test something specific.
However make test does not stop you from using make run or make package and in the later if your code is wrong it will not compile and point out why.
