Increase code coverage across different modules (easy ones)

🐞 Problem The goal is 100% code coverage. It’s not a very realistic goal because sometimes we lack the knowledge to do so. But I am listing some of the parts, where coverage can be increased easily.

🎯 Goal

Try to target these files. The lines untested would be marked red here.

• coordinates/core.py (#394)
• ijit.py (#397)
• symbolic/vector.py
• symbolic/tensor.py
• plotting/hypersurface/core.py
• plotting/rays/shadow.py
• rays/shadow.py

💡 Possible solutions

• What is coverage
• tests are present in src\einsteinpy\tests\test_<module name>\test_<file name>

Hey i’m still taking a bit too much time on it , im currently creating tests for coordinates/core if anyone wants to work on the other files please go ahead.

Open a PR with whatever you have, we’ll refine it over there.

Also @shreyasbapat and @ritzvik i fail to find a test module for coordinates/core file should i make one or insert my tests in an existing test module for coordinates. Thanks again.

Put them in test_coordinates/tests_coord_transform.py.

Working on this , will create PR soon.
