Test automation has turned unit testing into a standard practice in software development. Too often, unit testing doesn’t deliver the project quality and feedback speed developers expect. The right unit test suite gives great outcomes and is vital to delivering quality software; the wrong tests can break your code, drag on with bugs and upkeep costs, and take more time to fix than they save. Ensuring your testing suite maximizes its potential isn’t about writing more tests—it’s about implementing the best practices that give real value and minimise upkeep costs.
