The record

Purpose: Dextool Mutate is a C/C++ mutation testing tool that evaluates whether tests detect artificially injected faults.
Reports: It can produce console, compiler warning, JSON and HTML reports.
Test analysis: It identifies useless, redundant and near test cases to help improve a test suite.
Incremental runs: It saves run state in SQLite, allowing interrupted test phases to resume and previous results to be reused as code changes.
Pull request workflows: Change-based testing can focus analysis and tests on changed lines, with HTML or JSON reports for the diff.
CI integration: The documentation describes Jenkins usage and says the approach should work with any CI server setup.
Embedded systems: Users can write a custom analyzer to interpret test output, including results from embedded test setups.
Project integration: The tool integrates without requiring modifications to a project's build system.
Platform and dependencies: The project documents Ubuntu installation and lists LLVM/Clang, CMake, SQLite and a D compiler among its build and run dependencies.
License: The repository's LICENSE file identifies the source code license as Mozilla Public License, version 2.0.
Support and maintenance: The product page directs users to a Discord community, and says the project is maintained by Joakim Brännström.
Incremental testing: It saves run state in a SQLite database and can resume interrupted work and reuse results across runs.
Pull request workflow: It supports change based testing that runs mutants on changed lines and can produce HTML or JSON reports for a diff.
Embedded testing: For embedded systems, users can write a custom analyzer for test output, including signals for unstable tests.
