Continuing my adventure of adding unit tests for some of the core
Tidierfunctionality–this PR adds some tests related to@mutate.As noted in #115 ,
@mutatedoesn't work progressively (eg. you can't reuse a created variable in the same call). Since this is expected behavior and just a difference between R and Julia, I went ahead and added a docstring example explaining that you can't do this and to use separate calls to@mutateinstead.There's an outstanding question (#116) about whether
@mutateshould allow dropping columns by passingnothing. If the answer is "no" there, then I'll just remove that test as well.The rest of the tests pass and verify some of the core
@mutatefunctionality and expected behavior. 🎉
