^{Note: these values reflect the state of the issue at the time it was migrated and might not reflect the current state.}

Edit by TJR: The two patch files, by two different people deleted empty tests. Some version was merged to Python maintenance versions 2.7 and 3.3 (then on Mercurial) in Dec 2013: #63882 (comment). At that time, 3.4.0, released in March 2014, was tip. PR 24152 added docstrings to minidom.py, removed the empty tests, and revised existing tests. The author closed it due to lack of time when requested to split it into multiple PRs.

Many of the tests in test_minidom on 2.7 are empty, that is they are defined as "def testSomeFunction(self): pass".

I've marked this issue as "easy" since I suspect a lot of the tests can be either backported from 3.x, or removed if they don't exist in 3.x.

[bitdancer]

Well, we generally don't backport tests unless we are fixing related bugs. I think this should be left alone.

[zware]

In that case, the empty tests should be removed, since they currently report success on doing nothing.

[ajiteshgupta]

I have attached a patch. I deleted all the empty tests.

[serhiy-storchaka]

Rather than removing these empty tests it will be better implement them. Otherwise we can accidentally break the code.

I see a lot of empty tests on 3.x.

[bitdancer]

On tip it would indeed be better to implement them. The deletion is only for the released branches.

[JulianGindi]

I agree that they should be implemented. I'll fill them in and submit a patch in a day or so.

Issue bpo-19683: Removed empty tests from test_minidom. Patch by Ajitesh Gupta.

[zware]

Thanks for the removal patch, Ajitesh!

Julian, are you still working on implementing the tests on default?

[JulianGindi]

I have not started yet, wasn't completely sure of the status of this. I'll get going filling in those tests to the best of my ability.

[zware]

Alright, sounds good.

[JulianGindi]

So, it seems that there are many seemingly redundant tests and many tests whose intentions are unclear. I think this might be better suited for someone who has more experience with the xml minidom module. I have uploaded the work I have done but it is not complete.
