We’re excited to announce the release of Isolator++ v5.1, now with full support for 32-bit applications!
Why It Matters
With many development teams still maintaining and testing legacy 32-bit C++ applications, we wanted to ensure that you don’t miss out on the modern advantages of Isolator++ v5’s language-based API.
Now, with v5.1, you can:
✅ Write cleaner, faster unit tests
✅ Use our language-based mocking API—even in 32-bit builds
✅ Migrate from v4 more confidently with side-by-side support
✅ Keep using your existing test frameworks
And best of all—it’s still FREE for developers.
Use Case: Legacy Apps Meet Modern Mocking
Whether you’re testing an older embedded system, a legacy enterprise tool, or just haven’t yet switched to 64-bit, v5.1 brings the future to you.
You no longer need to rely on macro-heavy legacy syntax. Just update to v5.1 and enjoy writing expressive, discoverable tests with Isolator++’s intuitive API.
TEST(MyLegacyTest, HandlesOldCode) {
Isolator a;
auto fake = a.Fake.Instance<LegacyComponent>();
a.CallTo(fake->ComputeValue(5))
.WillReturn(42);
ASSERT_EQ(fake->ComputeValue(5), 42);
}
