Unit Testing with the Googletest C++ Testing Framework

2 days

Googletest is a framework for writing C++ tests on a variety of platforms (Linux, Mac OS X, Windows, Cygwin, Windows CE, and Symbian). It is based on the xUnit architecture and supports automatic test discovery, a rich set of assertions, user-defined assertions, death tests, fatal and non-fatal failures, value- and type-parameterized tests, various options for running the tests, and XML test report generation.

This course has two major objectives: 1) describe and apply good unit test practice, including test design and test performance, and 2) learn how to apply the Googletest framework with hands-on exercises.

Unit testing is a high leverage point to find defects early in a project when they are cheaper and easier to fix. Getting all your developers on the same page with this course is a big step toward higher software quality.
