Its Never Late to Write Tests

Have you ever had a small issue on your most important part of the code and you’re just scared to change it because it may break some other part of it? Or it has too many edge cases to test manually.

Tests Make You Confident

In life, you have more confidence when you know someone has your back. Let me explain more with a familiar example: imagine a great tech lead of yours. They trust you, they back you in situations, and if you make a mistake, they tell you about your mistakes before anyone else sees them. So you do better with their support. That is what tests do: they have your back. They support you.

The Goal of Testing

The goal of testing is not that you find the bugs immediately — they may even slow you down — but the main goal of testing is that it makes the code easier to change in the future. You don’t have to worry about breaking other parts or missing an edge case.

It’s Never Late to Write Tests

Believe me when I say it: It is never late to write tests. Take small steps: write some unit tests for your most important functions, slowly complete them, and jump to some integration or end-to-end tests. It starts slow but it makes your life way faster in the future.

Leverage AI in Writing Tests

Tests themselves are not something complex. Don’t think that you didn’t write many tests in the past so it is a hard thing. It is mostly a simple procedure: describe the flow, explain what it does, run the code, and expect a result to be what you have in mind. It is that simple.

Although it is usually a simple task, writing a lot of tests may be time-consuming. That’s where AI can help you.

Don’t worry, it will not replace you :) It is here to help you. Put your guard down and take its helping hand. Set up an agent on your codebase and brighten the road for it. Prioritize your important codes and you can see how fast you can write tests with AI. But keep in mind, like every task you do with AI, do not blindly do them. Check the result, ask it if you don’t understand a test, check if all the edge cases are covered.

Conclusion

Many of us were in a situation that we worked in a fast-paced environment where we had no time to write tests or our team did not prioritize tests. But small good behaviors like testing help us a lot in the future. Try to establish this in your team’s culture, and remember IT’S NEVER TOO LATE TO WRITE TESTS.
