Many operators don't have unit tests.

[zheng-da]

Our Python unit tests don't cover all operators. Recently, I found softmax activation was never tested and the test has been added in #10918. Currently, the backward computation of norm doesn't have GPU tests. I'm afraid more operators don't have unit tests.

Also #10868

We need to make a list tracking missing unit tests

[zheng-da]

can we create a list and somehow still keep track of them?
not sure doing something like below is a good way.

• norm backward

[anirudhacharya]

• check_numeric_gradient for FFT operator

[anirudhacharya]

initializer.py has very less test coverage

• Orthogonal Initializer
• Bilinear Initializer
• MSRAPrelu Initializer
• Mixed Initializer

[anirudhacharya]

Missing Gradient Checks - #13254

Missing Optimizer tests -

• Large batch BSGD
• Delay compensation asynchronous SGD
• SGLD
• AdaDelta
• Adamax
• Nadam

[hanzhaogang]

@zheng-da What skills and knowledge are required to write the test code? How do we test operators? Checked the test_subgraph_op.py whihc I think should be a test for the subgraph operator in the incubator-mxnet/tests/python/unittest/ package but still have no idea how to contribute.

Hi @anirudhacharya ,

It's been a while since the checked missing unit tests last year, and I checked Nadam has test, I would appreciate if you can point me where can I find the latest list of missing unit tests.

Many thanks,

[anirudhacharya]

@cchung100m I am afraid this is the only list of missing unit tests. I have updated the list based on my knowledge.
