Improve testing coverage

[vgvassilev]

Check codecov and suggest tests that increase the untested parts of the project.

I was interested in improving the test coverage. But I am not able to see the develop branch coverage in Codecov. Maybe it is due to the missing BASE report issue. Currently I am only seeing coverage reports for branches from @AdityaPandeyCN in Codecov and not for develop.

Should I look at the coverage from the latest merged branch to understand the current coverage state.

Since your comment was posted on March 5th.
Check the link below again, the develop branch code coverage just got updated on March 9th, 2026.

I am able to see it just fine.

I looked through Codecov, and aside from legacy TTree files, src/rntuple/RAMNTupleRecord.cxx lacks most test coverage.
I just submitted a PR for RAMNTupleIndex::IndexGetRowsInRange(), waiting for workflow approval.

Edit: Thanks!
