Section 2: Ensuring Correctness of Software at Scale

Overview

Teaching: 5 min
Exercises: 0 min
Questions
  • What should we do to ensure our code is correct?

Objectives
  • Explain the testing tools, techniques, and infrastructure that will be used in this section.

We’ve previously looked at building a suitable environment for collaboratively developing software. In this section we’ll look at testing approaches that help us ensure that the software we write is actually correct, and how we can diagnose and fix issues once faults are found. Using such approaches requires us to change our practice of development. This can take time, but potentially saves us considerable time in the medium to long term by allowing us to more comprehensively and rapidly find such faults, as well as giving us greater confidence in the correctness of our code. We will also make use of techniques and infrastructure that allow us to do this in a scalable and more performant way.

Tools for scaled software testing

In this section we will:

Key Points

  • Automated testing can help determine if our code is running correctly, as well as save us time in the future.

  • Parameterisation and Continuous Integration can help scale and further automate our testing process.
