Systems and methods for reducing storage required for code coverage results

A system comprising:

• one or more processors;
• one or more non-transitory computer-readable storage media storing sequences of instructions which, when executed by the one or more processors, cause the one or more processors to:
• receive new code coverage analysis data for a new code coverage analysis performed on an updated version of a particular source code base and a test suite, wherein the particular source code base is maintained in a source code repository of a version control system;
• parsing a previous code coverage commit stored at a code coverage result repository of the version control system to identify a first code coverage file that includes code coverage data for a first source code file, and a second code coverage file that includes code coverage data for a second source code file, wherein the first and second source code files are associated with a previous version of the particular source code base;
• comparing the new code coverage analysis data to the previous code coverage commit to determine that the first code coverage file is unmodified and that the second code coverage file has changed;
• and
• generating a new code coverage commit for the updated version of the particular source code base, comprising:
• a link to the first code coverage file stored in the previous code coverage commit;
• and
• a modified version of the second code coverage file comprising changes to the second code coverage file that resulted from changes made to the updated version of the particular source code base.
