Report for Assignment 1

Project chosen

Name: pygame

URL: https://github.com/pygame/pygame

We used lizard in the terminal to count the number of lines of code (NLOC). NLOC: 113408. From these NLOC, ~48992 were in Python as 43% of this project consists of Python.

Programming language: Python

Coverage measurement

Existing tool

We used the tool Coverage.py. Steps we took to do the test:

1. Enter the repository path in terminal.
2. Inside the repository directory, we went to path "/test" by using cd test.
3. Execute the coverage tool on the inbuild unit tester with the command: coverage run ..
4. After execution, the command coverage report is ran to get the coverage test results which will be shown below.

Coverage improvement

Individual tests

Test surfarray_tags.py

Screenshot before enhanced coverage improvement

Screenshot of enhanced coverage improvement

The tests show some overhead tests. In our case, we will skip the package tests and will only look at the surfarray_tags.py. The coverage was previously 58%. The enhanced test has a coverage of 83%. The coverage is improved because I added two advanced tests to test whether or not the imported libraries worked. These newly added tests did not branch out much. There is only a small branch in the second test for the exception handling. This improved the branch coverage significantly.
