Description Patrick Ohly 2017-07-05 06:45:32 UTC 
Sometimes it may be useful to run tests in a certain order, for example fast ones first to abort early when there are failures.

This used to work, but with the current runner tests seem to run in the order in which they are discovered, not in the order in which they are given on the command line.

Example in refkit:

$ oe-selftest --list-tests | grep compat

Comment 1 Patrick Ohly 2017-07-10 12:57:26 UTC 
Probably related and might be fixed at the same time, so let me just add it here: invoking "oe-selftest -r foobar" success instead of failing with an error about "foobar" not being found.

$ oe-selftest -r foobar

Hi Patrick,

We have a separate bug for this, see,

https://bugzilla.yoctoproject.org/show_bug.cgi?id=11645

Comment 3 Jair Gonzalez 2017-09-14 21:16:12 UTC 
The change is not trivial, as the current OEQA framework extends the upstream unittest library which uses recursion to discover the test cases, and sorts them on alphabetical order by default. It is possible to change the default unittest behavior and re-order the test cases afterwards on the way specified on the command line, but some other aspects need to be considered. For example, the framework and the oe-selftest tool allow to specify modules, classes or test cases, or any combination of them. Also, with the inclusion of dependency decorators, the order of test cases is re-arranged according to their dependencies. Finally, the framework also allows the possibility to specify a module manifest file to list the tests to execute, so it may be necessary to re-order the tests in a similar way as specified in the file if that option is used, to have a consistent behavior.
Considering we will be changing the default unittest behavior, it also may be convenient to have a new option in the tool to allow to specify the required order.
According to this, and this item's priority, I'll modify its target milestone to 2.5 M1.
Comment 4 Sangeeta Jain 2019-10-03 07:41:56 UTC 
With current testcases in oeqa/runtime, the order in which test cases are run doesn't really matter.
