At Typemock, we’re committed to making unit testing even the toughest C++ code easier and more accessible. Following our major strides toward a cleaner, real API in Isolator++ v5, we’re excited to announce the release of Typemock Isolator++ v5.2.0!
If you’re testing legacy C++ code, faking hidden types, or dealing with native libraries, this update is built for you.
What’s New in C/C++ Unit Testing with Isolator++ v5.2.0
✅ New API Update: Better Type Faking
- We’ve introduced
A::Type<type>, which now supports faking argument types of classes without public constructors. - Breaking Change: The older
A::Any(type)has been discontinued in favor of the new, more consistent API.
Why this matters: Real-world C++ often hides types behind non-public constructors for security and design reasons. Now, you can fake and test them without painful workarounds.
✅ Support for Faking DllImport Methods
- Isolator++ v5.2 now supports faking methods imported from DLLs. (learn more about DllImport).
Why this matters: Need to test code that calls into native libraries? Now you can mock those interactions safely, without executing real native code or setting up complex environments.
✅ Upgraded API Documentation
- We’ve expanded and polished our API reference documentation to make discovering and using Typemock features easier than ever.
Why this matters: Whether you’re a Typemock veteran or just starting out, clearer docs mean faster onboarding, better tests, and less friction.
Why These Changes Matter
Modern C++ codebases often involve tightly controlled types, platform-dependent libraries, and legacy systems not designed with testability in mind. With Isolator++ v5.2, we’re removing even more barriers:
- Mock hidden types without rewriting your production code.
- Test DLL-imported methods without hitting the native platform.
- Work faster and smarter with better docs and a more intuitive API.
These improvements keep you focused where it matters most—writing meaningful tests, not fighting the framework.
