Testwell CTC++ 10.2

Testwell CTC++ is a professional code coverage analyzer for C and C++ that helps teams quantify and improve test effectiveness, including on deeply embedded targets. It instruments your source code and reports precise structural coverage, supporting function, statement, branch/decision, condition, and MC/DC levels. Designed to be compiler- and target-agnostic, it works across desktop builds, cross-compilers, microcontrollers, and RTOS environments with minimal runtime and memory overhead, making it suitable for resource-constrained systems.

Key capabilities:

• Measures coverage up to MC/DC for safety-critical verification
• Works with virtually any compiler, build system, and target/host setup
• Merges results from multiple test runs and test levels (unit, integration, system)
• Generates detailed text, HTML, and machine-readable reports for audits and CI
• Supports compliance efforts for standards such as ISO 26262, DO-178C, IEC 61508, and IEC 62304, with qualification materials available
• Optional add-ons extend coverage measurement to Java and C#
• Integrations and command-line tooling fit into automated CI/CD pipelines

Typical uses include ensuring sufficient test depth in automotive, aerospace, industrial, and medical software, where demonstrable structural coverage is required.
