Test Driven Development with C++
Agile development is feedback driven development. Faster feedback loops are essential to ensure that the code that worked yesterday continue to work today, after the most recent changes. Come to this workshop to gain an in depth hands on experience to design and implement automated unit tests for C++ applications. Learn how to use mocks/stubs and when to actually use them. Also, learn how AI can help with some of these tests creations and where it falls short. After this workshop you will be able to apply and also guide your teams to make use of this highly essential sustainable agile practice.
This workshop is hands-on and includes several coding exercises. Attendees are encouraged to pair and work on the labs. The workshop involves live-coding and is highly interactive. The topics covered include:
