Have you ever wondered if all the rules you write are actually enforced? That’s where SimpleCov comes in.
What is SimpleCov?
SimpleCov is a tool for Ruby programmers. It’s like a detective looking at your code and identifying usable and unusable parts.
While Ruby offers a built-in Coverage library, SimpleCov streamlines the process. It provides an easy-to-use interface for filtering, grouping, formatting, and displaying coverage data. This lets you set up a comprehensive code coverage suite with minimal effort (just a couple of lines of code!). For more information, visit https://github.com/simplecov-ruby/simplecov
How does it work?
- You add SimpleCov to your project.
- You do your tests as usual.
- SimpleCov checks which parts of your code are used during testing.
- It creates a report that lists used (covered) and unused parts.
What is the status of the report?
Generally the report shows:
- A percentage of how much your code has been tested
- A list of files, with a label indicating how well each file is covered
- Green claims it has been fully tested
- Yellow indicates partial testing
- Red indicates no maintenance at all
Why should you care?
Using SimpleCov can help you:
- Find the parts of your code that you forgot to test
- Remove unused code
- Be more confident that your program is working properly
SimpleCov is a handy tool that helps programmers ensure their code is properly tested. With tools like SimpleCov, programmers can write better, more reliable software!
