Develop Comprehensive Testing Suite: First Steps

[WarrenZhu050413]

Related to #8 , #13 and #9, the package needs a set of tests that could be automatically checked by CRAN/github actions/developers to increase reliability and increase development speed.

In order to do so, need to identify the core set of tests.

Currently, thinking of first developing a sequence of rudimentary tests that tests that all the functions run without error and the shapes and types of the outputs are correct.

Not entirely sure what should follow. @cjerzak any thoughts?

[cjerzak]

Core test might just be two things - one rerandomization procedure (Gen Randoms then randomization test) for exact case and another for monte Carlo case. So 4 fxn calls?

We'll want these tests to run fast to enable quick sanity confirmation

For the paper evals We'll have a fuller suite of analyses

[cjerzak]

For evals on the 4 fxn calls, we want correctness, speed checked primarily, along with array output shapes. Among possibly other things

Currently in RunAll_TestSuite.R.

To Do:

Need to augment it using testthat. Further, split the tests up into separate unit tests.
