Collaborative mutation testing
Find the mutants tests couldn't kill.
A collaborative platform for discovering, reproducing and investigating surviving software mutants.
A surviving mutant is not automatically a weakness in the test suite: it may be equivalent, invalid or environment-dependent. MutantHub exists to investigate each one carefully.
01
Explore real code
Browse registered open-source repositories at an exact commit in a read-only, IDE-like viewer.
02
Submit surviving mutants
Pick a line, describe the mutation as a git diff and record how you built and tested it.
03
Reproduce results
Other contributors re-run the mutant in their environment and report what they observed.
04
Kill mutants with better tests
Discuss equivalence, find the missing test and record when a mutant is finally killed.
