TODO: consider implementing the following tests for a better code coverage
|
|
- correctness
|
|
- bad input argument (if applicable)
|
|
- data corruption around/of input and output
|
|
- correctly work with nested parallelism
|
|
- check that algorithm does not require anything more than is described in its requirements section
