devel stuff: notes for test update (bladen)

Test types:

basic
- just tests the simplest use case works for ALL possible input objects
data
- similar to basic, but uses different input datasets
parameter
- tests the functionality of a specific parameter (or set of parameters)
edge.case
- tests for warnings or odd scenarios
error
- tests that a specific error is raised in the appropriate scenario

auroc
- mint.block.(s)plsda needs test cases once auroc() is implemented for these object types
background_predict
cim
circosPlot
diablo
network
pca
perf.diablo
perf.mint.splsda
plotIndiv
plotLoadings
- due to the nature of PR #180, these test cases have barely been worked on. Once that PR is merged, come back and complete the upgrade of this document

internals-.get-pch
- doesn't use any mixOmics datasets
- explore different parameters and error states
internals
- tests .get.ind.colors,.are.colors, .get.colors, .get.character.vector, .check_test.keepX and .check_ncomp
- see if there are more internals to test, explore different datasets with these tests
plotVar
- needs tons of work, only one test
predict
- 4 datasets, mint.splsda, block.splsda, pls, plsda
- add any remaining methods (eg splsda) and test for more parameters
tune.block.splsda
- only one test (one dataset), no parameter tests
tune.mint.splsda
- two tests, one dataset. test more parameters (not just signif.threshold)
tune.spls
- one test, one dataset, with/without parallel
- needs work
tune.splsda
- one test, one dataset
