Unit testing company Typemock has released the latest version of its C++ testing solution, Isolator++.
Isolator++ 5.4 features a completely redesigned API built around modern C++ constructs and lambdas, rather than on macros. According to the company, this allows for cleaner, more expressive test code, as well as improving IDE integration and code completion.
This redesign also enables LLMs to more reliably generate unit tests that follow Typemock conventions, which can then be iterated on to improve edge cases and coverage.
Users will also now be able to control and verify constructor calls, including base class constructors, allowing them to test complex object creation paths and inheritance hierarchies.
Additionally, this release adds During Filters, which restricts mocks to specific runtime contexts like particular models, call paths, and scopes. The company says this will cut down on unintended side effects and improve test accuracy.
“C++ development has evolved, with Linux now central to cross platform projects” said Eli Lopian, CEO of Typemock. “Isolator++ 5.4 brings Linux developers the same powerful testing tools long available on Windows, with a modern API that enables precise mocking and verification without changing production code. This release marks a major step forward for C++ testing.”
