QA:Repodata validity test case

Description

A simple check that the repodata (yum metadata) for a given repository is valid.

How to test

1. open repodata/repomd.xml
2. confirm that there is a <data> element with type="primary" or type="primary_db"
3. confirm that there is a <data> element with type="filelists" or type="filelists_db"
4. confirm that there is a <data> element with type="other" or type="other_db"
5. confirm that there is a <data> element with type="group" or type="group_gz"
6. For each element listed above, check that the file listed in the <location> element is:
   • present,
   • non-empty, and
   • matches the checksum listed in the <checksum> element

Expected Results

1. repomd.xml exists
2. repomd.xml contains entries for primary, filelists, group, and other metadata
3. the files referenced in those entries are present, non-empty, and match the listed checksums
