As a Ruby developer, you should write tested code with RSpec for several reasons:
- Decomplect as you code: Coding without writing tests involves keeping lots of context in your head: Your variables, your data points, your other variables & data points, the calling code, the other parts of the system. Writing code with test means you don’t have to keep the whole application context in your head. Instead, the process allows you to focus on just one thing at a time. The integration and system test suite acts as a guarantee that you are still making all the pieces fit together. This significantly reduces the stress associated with coding a complex system.
- Ensure code quality: Writing tests with RSpec helps you to ensure that your code works as intended and meets the specified requirements. It also helps to catch errors and bugs early in the development process, making it easier to fix them before they become bigger problems.
- Enhance code maintainability: Tests help to document how the code should behave, which makes it easier to maintain and refactor code over time. By writing tests with RSpec, you can make sure that your code remains consistent and predictable even as it evolves.
- Facilitate collaboration: Tests provide a common language between developers and can help facilitate collaboration between team members. Writing tests with RSpec makes it easier for other developers to understand your code and make contributions to it.
- Boost confidence: Having a comprehensive suite of tests can give you confidence in your code and help you to catch regressions before they reach production. This can ultimately lead to a better user experience and improved customer satisfaction.
Overall, writing tested code with RSpec is an essential part of the software development process that helps you to produce high-quality, maintainable, and reliable code.
