    Parasoft

    Parasoft

    Parasoft

    Parasoft C/C++test provides a built-in, end-to-end unit testing framework that automatically generates tests, mocks, stubs, and assertions to isolate the unit under test, and detects failures, unsatisfied expectations, and coverage gaps in real time during execution. Tests can be created via graphical editors, guided workflows, and the Test Case Explorer, and run on host, simulator, or target hardware to meet safety-critical requirements. Unlike tools that store test inputs in proprietary formats, C/C++test generates test cases as source code, with parameter values initialized the same way as in production, keeping tests reviewable and version-controllable. It also integrates with open-source frameworks like GoogleTest, Boost.Test, and CppUnit to add structural coverage (statement, branch, MC/DC), reporting, and CI/CD automation.
