Most devs stop writing tests when it feels like enough. But feeling isn't a strategy. Tests come with a cost!. 👇 Learn to test with math, not vibes: #softwaretesting #unittesting #dev

Do you really need unit tests? . Well, maybe yes, maybe not. If it's okay for you that developers spend 70% of their day debugging their code, then it's fine to go without unit tests. ---.Join 5,200+ engineers: . #tdd #unittesting

It's NOT enough to say we have unit testing. It's NOT enough to say we've got 100% coverage. If you haven't run mutation testing, you don't know if your tests are protecting you at all. ---.Join 5,200+ engineers: . #tdd #unittesting

Quick tip after migrating to Angular 16 with standalone components: If you're providing services directly in a component, you'll need to update your testing approach. Just spent a few hours debugging failing unit tests because of this change💡. #Angular #UnitTesting #WebDev

Developers care about the code. Business cares about outcomes. If you ever want to have influence on management decision making, communicate the business impact, not the code. ---.Join 5,200+ engineers: . #tdd #unittesting

Code coverage is dangerous because it gives the illusion that the tests are protecting us, when in fact, they might not be. ---.Join 5,200+ engineers: . #tdd #unittesting

The tested code may rely on external services or be time-dependent, which can result in varying outputs. A mock object can control the behavior of a real object in a testing environment by simulating responses from external services. #UnitTesting #Mocking #Python

Unit testing is the foundation of building reliable applications! 🧪 Today, diving into concepts like mocking, mockingResolvedValue, and spying to write tests for a simple Express app. 🚀. @kirat_tw @100xDevs . #UnitTesting #100Devs #ExpressJS #TestingTools

During the years, I have taught several courses on ⚙️ automated testing (#UnitTesting), some of them focused on #RustLang. I have published the first part in my blog:.All of them are hands-on learning 🧑‍🎓 . I hope you like them. RT & Comments appreciated.

If pyinstaller and unit tests went on a date, who pays for dinner? 🍝🤣. Source: #CodeTesting #TechTips #UnitTesting #Debugging #unittest #unittests

🎉 Just ran my test suite, and everything's green! ✅ All tests passed, ensuring our auth service is solid. 🚀 #TypeScript #NodeJS #UnitTesting #DevLife. #EmergencyTrailer

🚫 Do NOT test internal implementation details. ✅ DO focus on the expected behavior of the code. If you tightly couple your tests to implementation details, any small change to the code will break the tests. Join 4,000+ engineers: #tdd #unittesting

TDD does NOT slow you down. TDD is about being minimalistic - you write just enough code to make the failing test pass. This avoids adding premature features or overengineering. Join 4,100+ engineers: #tdd #unittesting #softwaredevelopment #optivem

Higher-level tests help protect us against user-facing regression bugs, whereas lower-level tests help us further optimize maintenance costs. ---.Join 5,200+ engineers: . #tdd #unittesting

If my test variable had legs, how would it walk to the next test in pytest?" 🤔👣. Source: #CodeQuality #DevTips #Unittesting #OpenSource #variable #test

When testing, we want to fail fast. If tests take too long, we might delay running them, leading to more complex bugs later on. Without fast feedback, we’re building software blind. Join 4,300+ engineers: #tdd #unittesting #softwareengineering
