OK, so I temporarily fix my script to prevent the error, but now I have a
more mysterious issue: looks like `loadTestsFromNames()` doesn't return?
I've modified `commands.py` like so:
import tests
loader = tests.Loader()
with open('/tmp/bar.txt','a') as fp:
fp.write('loader is {}\n'.format(loader))
try:
zzz = loader.loadTestsFromNames(['tests'])
with open('/tmp/bar.txt','a') as fp:
fp.write('DONE loading zzz= {}!\n'.format(zzz))
except Exception as exc:
with open('/tmp/bar.txt','a') as fp:
fp.write(str(exc))
runner = tests.Runner()
And here's attempt to run:
cauthu @ laptop:~/upstream-grpc/tools/run_tests$ cat /tmp/bar.txt
cat: /tmp/bar.txt: No such file or directory
cauthu @ laptop:~/upstream-grpc/tools/run_tests$
cauthu @ laptop:~/upstream-grpc/tools/run_tests$ ./run_tests.py -l python
--compiler python2.7 -r SanityTest
Unexpected error getting flaky tests: <type 'exceptions.ImportError'>
PASSED:
/home/cauthu/upstream-grpc/tools/run_tests/helper_scripts/build_python.sh
[time=1.8sec; retries=0:0]2017-09-21 13:36:47,390 detected port server
running version 20
2017-09-21 13:36:47,418 my port server is version 20
SUCCESS: All tests passed
cauthu @ laptop:~/upstream-grpc/tools/run_tests$
cauthu @ laptop:~/upstream-grpc/tools/run_tests$ cat /tmp/bar.txt
loader is <tests._loader.Loader object at 0x7f98821aca10>
cauthu @ laptop:~/upstream-grpc/tools/run_tests$
So it claims that all tests passed, there doesn't appear to be any
exception with `loadTestsFromNames`, and yet `DONE loading!` is not
appended to `/tmp/bar.txt`?
I'm super confused!? Any help appreciated. Thanks!
