Imports only run in Python 3 sandboxes, so the tests here only run in Python 3.
|
|
The test files in this directory have been renamed to look like 'import_xls_test.py' instead
|
|
of 'test_import_xls.py' so that they're not discovered automatically by default.
|
|
`load_tests` below then discovers that pattern directly, but only in Python 3.
|
|
This allows the tests to be skipped without having to specify a pattern when discovering tests.
|
|
The downside is that if you *do* want to specify a pattern, that probably won't work.
|
|
|
|
The reason for this method is that there's a bug in Python 2's unittest module
|
|
regarding packages and directories that we must handle.
|
|
This means that in Python 2, I wasn't able to prevent files like 'test_import_xls.py'
|
|
from being discovered automatically regardless of what I did in `load_tests`.
|
|
|
|
Compare https://docs.python.org/3.9/library/unittest.html#load-tests-protocol
|
|
vs https://docs.python.org/2/library/unittest.html#load-tests-protocol
|
|
|
|
from "If discovery is started" on both pages. Note in particular:
|
|
|
|
> Changed in version 3.5: Discovery no longer checks package names for matching pattern
|
|
due to the impossibility of package names matching the default pattern.
|
|
|
|
The reason for skipping entire files from being discovered instead of skipping TestCase classes
|
|
is that just importing the test file will fail with an error, both because we manually raise
|
|
an exception and because dependencies are missing.
