* ENH: Add traceback-skip to `assert_array_compare`
* TST: Add tests for arraycoercion
These tests have many xfails (some technically maybe not correct),
which describe in detail what will change when merging the
array-coercion changes; since all of those xfails are going
to be removed.
* TST: Add test for empty sequences
* TST: Add tests for bad self-mutating sequence inputs to np.array
These should never happen and rightly should lead to undefined
behaviour (and preferably errors), but they excercise some more
tricky code branches and should probably not crash.
* Simplify the "all scalars" logic (hardcode) and fix complex cases
* MAINT: Some cleanup, and xfail pypy
PyPy seems to have issues with int(numpy_complex), maybe because
it gives a warning during conversion (python does not define it).
So simply mark it as xfail, it should work in my branch.
Also some smaller cleanups.
* TST: Add some further test, re-add missing rational
* MAINT: Make rationals optional, because they fail some tests currently
The failures will go away, since this must again be related to
implemetning int() and float().
* Update numpy/conftest.py
* MAINT: Fix strings and use pytest.param to clean things up
* TST: Add tests for 0-D array-like input to np.array() corner-cases
* TST: Improve parameterization IDs to get better printing at -vv
