Testing Superpowers: Using CLion to Add Tests Easily – Webinar Recording

Anastasia Kazakova

The recording of our webinar, Testing Superpowers: Using CLion to Add Tests Easily, with Clare Macrae, is now available. Subscribe to our community newsletter to receive notifications about future webinars.

This webinar was produced in response to a question someone asked in Arne Mertz’s "Refactoring C++ Code" webinar: "What can we do if we don’t have tests on the project and can’t easily check the changes introduced by refactorings?" Our speaker, Clare Macrae, is an independent consultant who helps teams streamline their work with legacy and hard-to-test C++ and Qt code. She is also a core contributor to the Approval Tests for C++ library, which makes it really easy to cover legacy code with tests. In this one-hour webinar, she discusses how to add tests for untested code, what the Approval Test approach is, and how code coverage tools can guide your testing.
