add unit tests #19
Description
Add unit tests using R package tinytest
- to test if embeddings based on list approach and file based approach are the same for different settings of the algorithm
- to test if the embeddings are the same across platforms
- to test if the embeddings stay the same when the internals are changed
- to test if the resulting dimension of the embedding is correct
- to evaluate inconsistent input data
- to evaluate if the expected tokens are in the data
- to evaluate different hyperparameters of the model
avoid adding complex package dependencies in Suggests to avoid continuous integration + CRAN build & dependency issues.
