We need to maintain legacy applications that were not built to facilitate unit testing. Without Typemock we would be completely unable to effectively test these applications. Typemock boosts productivity because you do not have to explicitly code from the ground up with testing in mind, which can be difficult to handle. Typemock has been able to cover up the coupling and dependency sins that we all have leaked into our applications from time to time.

Case Studies



Intronis msp solutions doubles unittest coverage in new code. The team required the power of Typemock to mock Legacy Code, including static and private methods.

DIPS needed a solution for unit testing their existing code (legacy code), which was not designed with testability in mind. Typemock enabled their developers to write test against untestable code without significant modifications to the code. This helped DIPS to increase their number of tests by 190% from 1,100 to 3,200 tests!

Corillian embraced TypeMock.NET wholeheartedly as it is an easy-to-use tool for Unit testing. Within two months their number of tests increased by 500%, test coverage increased by 50%, and tests are 25% faster to write!

By using Isolator, TERMA have increased their code coverage from 0% on their old platform to an average of 70% on their new platform .

Black Marble discovered that unit testing SharePoint applications is only possible with Typemock Isolator, and as a result, increased the code coverage in related projects by 80%.
