A computer implemented method comprises receiving code coverage analysis data in respect of a code coverage analysis performed in respect of a particular 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; identifying a code coverage result repository of the version control system, wherein the code coverage result repository is associated with the particular version of the particular source code base; generating a new storage version based on the code coverage analysis data; obtaining a delta between the new storage version and a previous storage version of the code coverage analysis data; and committing the delta to the code coverage result repository of the version control system as a new version to de-duplicate code coverage analysis data.
