Improve test coverage

[ablaom]

This is currently at 9%. I would say that until coverage is above 70%, adding tests should take priority over adding functionality.

Unit Tests

• dtw_distance - equal length of time series

• select_sort

• InvFeatureGen

Integration tests

• TSF

• KNN

Remaining

• dtw_distance - handling unequal length of time series.

There are some extra functions in utils.jl which are not in use as of now.

• TSdataset - Used to covert the ts files to csv files.

@ablaom for Integration tests I have added check Accuracy > value or should we use predict with random number to get reoccurring output?

Do we need tests for data loading functions?

• load_dataset

• load_ts_file

• ts_dataset

• load_from_tsfile_to_NDArray

• load_NDdataset

Looking good. 60% is great boost 🎉

The best tests might be a very simple example where you can work the answer out by hand and check for approximate equality (isapprox or ≈). But this can often be difficult. That's why it's good to break down your algorithm into lots of smaller functions that you can do this for. So, I think Accuracy > value is okay, where value could be some baseline model prediction (eg, constant, feature-independent, prediction).

You can use the codecov tool to find where coverage is low, then decide which of those areas should be prioritized. Follow the links from the codecov .

Couldn't hurt. Start with those with the most complex logic.

• select_sort

• InvFeatureGen

Where are these? I could not find them.
