"""
|
|
Whitelist is applied first. The blacklist is executed against the set of
|
|
tests returned by the whitelist.
|
|
If whitelist is empty, all available tests are fed to blacklist.
|
|
If blacklist is empty, all tests from whitelist are returned.
|
|
|
|
The syntax for white-list and black-list is as follows:
|
|
- lines starting with # or empty are ignored
|
|
- lines starting with "+" are whitelisted
|
|
- lines starting with "-" are blacklisted
|
|
- lines not matching any of the above conditions are blacklisted
|
|
|
|
The match for each line gets added a "^" in the beginning,
|
|
so the regular expression should account for that.
|
|
|
|
For example, the following scenario:
|
|
|
|
run all the smoke tests and scenario tests,
|
|
but exclude the api.volume tests.
|
|
|
|
is implemented as:
|
|
|
|
+.*smoke
|
|
+tempest\.scenario
|
|
-tempest\.api\.volume.*
