Hey and Welcome Emerson!
You can start with Release Validation testing. In Release Validation all
you need to do is to check the nightly/TC/RC against certain criteria. For
example, let's take the latest nightly, you can run test cases which are
mentioned [1] and submit your results in the test matrix.
Note that each of the test cases[2] will have "How to test" section which
will have the steps (to be executed sequentially) and if the results match
with the expected results you can mark it as pass by editing the wiki page
{{result|PASS|<fas_username>}} . Always make sure to check for "Associated
release criterion" which can be found on the top of test case page , if
your test case fails you can mark it fail by editing the wiki page
{{result|FAIL|<fas_username>}} and file a bug at RHBZ [3] under Fedora.
You can always find the ‘current’ validation pages using these addresses:
https://fedoraproject.org/wiki/Test_Results:Current_Installation_Test
https://fedoraproject.org/wiki/Test_Results:Current_Base_Test
https://fedoraproject.org/wiki/Test_Results:Current_Desktop_Test
https://fedoraproject.org/wiki/Test_Results:Current_Server_Test
https://fedoraproject.org/wiki/Test_Results:Current_Cloud_Test
You can also do update-testing, update testing is where a tester tests a
package and gives out a +1 Karma for PASS and -1 Karma for FAIL. You can go
to
bodhi.fedoraproject.org where you can sort the packages with Fedora
Releases and tags viz "pending" & "testing" . You can read much
about
update testing here [4]. You can also, use fedora-easy-karma for giving out
feedback.
