Bug ID: 25092
Summary: Test suit is flaky if 2 tests have the same file name
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs

Classification: Unclassified
If we have 2 test case with the same file name then the test suit will become
flaky for those tests.
In some ordering of the events (most likely when the 2 test with the same name
run at the same time) one of the test will fail with the following error:
Traceback (most recent call last):

OSError: [Errno 2] No such file or directory
We should handle the case when 2 test have the same file name or explicitly
disallow it with some check at test case loading time.
