11 Exploring Testing Frameworks

Testing the code is an important part of software development. Although there is no support for testing in the C++ standard, there is a large variety of frameworks for unit testing C++ code. The purpose of this chapter is to get you started with several modern and widely used testing frameworks that enable you to write portable testing code. The frameworks that will be covered in this chapter are Boost.Test, Google Test, and Catch2.

This chapter includes the following recipes:

Getting started with Boost.Test
Writing and invoking tests with Boost.Test
Asserting with Boost.Test
Using test fixtures with Boost.Test
Controlling output with Boost.Test
Getting started with Google Test
Writing and invoking tests with ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
