Optimizing Angular Unit Tests for Faster Execution ⏳⏰
Introduction
Welcome readers! As our product evolves and new features are introduced, it’s crucial to write additional unit tests to ensure everything is working correctly. Unit testing involves testing small, isolated pieces of code in your application. However, this can lead to longer test execution times and delays, so it’s important to optimize them to minimize the time and resources. Follow me on this blog to learn techniques for optimizing unit tests in Angular applications.
Motivation: Who wants to wait ❕❓?
Optimizing your Angular unit tests can help us to:
- Improved development experience: Long-running tests can be frustrating for developers ⛔️
- Saving expenses: Pipeline time + the time the developer waits also is expensive 💸
- The CI build completes faster 📤
- Improved code quality: By running your tests more frequently and getting faster feedback, you can identify and fix issues with your code more quickly, which can ultimately lead to higher code quality. 📈
Steps to speed up Angular unit tests execution time 📗
Notice: “For the purpose of this demonstration, I have compiled a selection of unit tests from various open-source Angular projects to create a testing environment that closely resembles a real-world production environment.”
