In Detail

Testing your application often and early is a key consideration in modern web development. PHP developers using the high-performance PHP framework Yii have access to Codeception, a testing suite that provides comprehensive support for unit, functional, and acceptance tests. With Codeception, you will quickly learn how to create fast, stable applications using a test-driven development methodology. Learning Yii Testing embraces a testing-first strategy to guide you in the implementation of all possible types of tests, covering the core features of Yii 2. Starting with the nuts and bolts of testing, you'll walk through Yii 2's new functionality and improvements and learn how to begin testing with it. You'll explore the world of Codeception and gain insights into key topics such as testing in isolation and component integration tests.

You'll also learn to analyze testing information and improve the quality of your code. At the end of the book, you will be able to use automation tools to reduce your testing workload.
