README FOR IDLE TESTS IN IDLELIB.IDLE_TEST
|
||
|
|
|
||
|
|
The idle directory, idlelib, has over 60 xyz.py files. The idle_test
|
||
|
|
subdirectory should contain a test_xyy.py for each one. (For test modules,
|
||
|
|
make 'xyz' lower case.) Each should start with the following cut-paste
|
||
|
|
template, with the blanks after after '.'. 'as', and '_' filled in.
|
||
|
|
---
|
||
|
|
import unittest
|
||
|
|
import idlelib. as
|
||
|
|
|
||
|
|
class Test_(unittest.TestCase):
|
||
|
|
|
||
|
|
def test_(self):
|
||
|
|
|
||
|
|
if __name__ == '__main__':
|
||
|
|
unittest.main(verbosity=2, exit=2)
|
||
|
|
---
|
||
|
|
Idle tests are run with unittest; do not use regrtest's test_main.
|
||
|
|
|
||
|
|
Once test_xyy is written, the following should go at the end of xyy.py,
|
||
|
|
with xyz (lowercased) added after 'test_'.
|
||
|
|
---
|
||
|
|
if __name__ == "__main__":
|
||
|
|
import unittest
|
||
|
|
unittest.main('idlelib.idle_test.test_', verbosity=2, exit=False)
|
||
|
|
---
|
||
|
|
|
||
|
|
In Idle, pressing F5 in an editor window with either xyz.py or test_xyz.py
|
||
|
|
loaded will then run the test with the version of Python running Idle and
|
||
|
|
tracebacks will appear in the Shell window. The options are appropriate for
|
||
|
|
developers running (as opposed to importing) either type of file during
|
||
|
|
development: verbosity=2 lists all test_y methods; exit=False avoids a
|
||
|
|
spurious sys.exit traceback when running in Idle. The following command
|
||
|
|
lines also run test_xyz.py
|
||
|
|
|
||
|
|
python -m idlelib.xyz # With the capitalization of the xyz module
|
||
|
|
python -m unittest -v idlelib.idle_test.test_xyz
|
||
|
|
|
||
|
|
To run all idle tests either interactively ('>>>', with unittest imported)
|
||
|
|
or from a command line, use one of the following.
|
||
|
|
|
||
|
|
>>> unittest.main('idlelib.idle_test', verbosity=2, exit=False)
|
||
|
|
python -m unittest -v idlelib.idle_test
|
||
|
|
python -m test.test_idle
|
||
|
|
python -m test test_idle
|
||
|
|
|
||
|
|
The idle tests are 'discovered' in idlelib.idle_test.__init__.load_tests,
|
||
|
|
which is also imported into test.test_idle. Normally, neither file should be
|
||
|
|
changed when working on individual test modules. The last command runs runs
|
||
|
|
unittest indirectly through regrtest. The same happens when the entire test
|
||
|
|
suite is run with 'python -m test'. So it must work for buildbots to stay green.
|
||
|
|
|
||
|
|
To run an individual Testcase or test method, extend the
|
||
|
|
dotted name given to unittest on the command line.
|
||
|
|
|
||
|
|
python -m unittest -v idlelib.idle_test.text_xyz.Test_case.test_meth
|
||
|
|
|
||
|
|
To disable test/test_idle.py, there are at least two choices.
|
||
|
|
a. Comment out 'load_tests' line, no no tests are discovered (simple and safe);
|
||
|
|
Running no tests passes, so there is no indication that nothing was run.
|
||
|
|
b.Before that line, make module an unexpected skip for regrtest with
|
||
|
|
import unittest; raise unittest.SkipTest('skip for buildbots')
|
||
|
|
When run directly with unittest, this causes a normal exit and traceback.
