Automated software testing
💥 Developing automated tests 🧪 for your code can be 🕰 time consuming but its worth it knowing that future features or code refactoring will not break your work and give unnecessary ❌️ errors/headaches for the users. Spent 30 mins developing a new software feature and 2 hours writing a test for it. It was worth it to discover and fix a 🐞 bug. As bonus, I learnt some techniques to make them run 70% faster 🚀.
