Functions that lack test in QuTiP.

[AGaliciaMartinez]

These are some modules in QuTiP for which there are no tests written yet. I will try to write them since they are very useful to define what an operation should do. This facilitates the development of new data types.

• Eigen
• ptrace

I don't know all of them, but off the top of my head, the eigensolvers, ptrace and expect definitely have tests.

Hey Jake, thanks for pointing out that those test exist as at first I did not look beyond the tests in tests/core/data/! Indeed there is a test_expect.py (and similar for eigensolver and ptrace) in QuTiP but these seem to be testing Qobj level functionality. I was looking for tests similar to those in test_mathematics that I can inherit from and easily employ to test my own specialisations. I think that extending test_mathematics.py to provide tests for the above specialisations would be very useful. This allows QuTiP to define what the specialisations should do in a very concrete way and it helps future developers to develop new data layers.

From the discussion at yesterdays GSoC meeting, it seems that @hodgestar, @Ericgig and @quantshah agree although they suggested to extend test_mathematics in a different file for organization purposes as test_mathematics is already quite big.
