Summary
Understanding testing techniques is key to ensuring software works as intended and remains user-friendly, secure, and reliable. These methods range from testing small code units to validating user experiences or system performance under pressure.
- Start with basics: Learn about functional testing types such as unit, integration, system, and acceptance testing to ensure different parts of your software work individually and together.
- Cover non-functional needs: Focus on areas like performance, security, and usability testing to ensure the software meets speed, safety, and user-friendliness expectations.
- Explore advanced approaches: Use specialized methods like regression testing, smoke testing, and exploratory testing to address changes, system readiness, and unexpected issues efficiently.

Non-tech PMs often struggle with testing concepts. But understanding TDD and BDD has saved me countless hours of rework and team conflicts. ↳ Test-Driven Development (TDD) is: - Writing the test first, then building just enough to pass it. - Like saying "I want to verify payment amount doesn't exceed account balance" when developing payment app. ↳ Behavior-Driven Development (BDD) is: - Creating real-life stories about how people will use your product. - Like saying "When a user with $100 balance attempts to send $150, they should see an insufficient funds message" 𝗪𝗵𝗲𝗻 𝘁𝗼 𝘂𝘀𝗲 𝘄𝗵𝗶𝗰𝗵 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵? ✅ TDD works best when: → You need precise technical validation → Working with unit and functional testing → Developers or QA write the tests using programming languages Example TDD unit test in JavaScript: ('𝘴𝘩𝘰𝘶𝘭𝘥 𝘳𝘦𝘫𝘦𝘤𝘵 𝘱𝘢𝘺𝘮𝘦𝘯𝘵 𝘪𝘧 𝘢𝘮𝘰𝘶𝘯𝘵 𝘦𝘹𝘤𝘦𝘦𝘥𝘴 𝘣𝘢𝘭𝘢𝘯𝘤𝘦', () => { 𝘤𝘰𝘯𝘴𝘵 𝘢𝘤𝘤𝘰𝘶𝘯𝘵 = 𝘯𝘦𝘸 𝘈𝘤𝘤𝘰𝘶𝘯𝘵(100); 𝘦𝘹𝘱𝘦𝘤𝘵(() => 𝘢𝘤𝘤𝘰𝘶𝘯𝘵.𝘮𝘢𝘬𝘦𝘗𝘢𝘺𝘮𝘦𝘯𝘵(150)).𝘵𝘰𝘛𝘩𝘳𝘰𝘸('𝘐𝘯𝘴𝘶𝘧𝘧𝘪𝘤𝘪𝘦𝘯𝘵 𝘧𝘶𝘯𝘥𝘴'); }); ✅ BDD shines when: → You need stakeholder alignment → Testing user journeys or workflows → Non-technical team members need to understand tests The best part? BDD tests can be written by analysts, PMs, or POs as part of requirements: 𝘚𝘤𝘦𝘯𝘢𝘳𝘪𝘰: 𝘜𝘴𝘦𝘳 𝘢𝘵𝘵𝘦𝘮𝘱𝘵𝘴 𝘱𝘢𝘺𝘮𝘦𝘯𝘵 𝘸𝘪𝘵𝘩 𝘪𝘯𝘴𝘶𝘧𝘧𝘪𝘤𝘪𝘦𝘯𝘵 𝘧𝘶𝘯𝘥𝘴 𝘎𝘪𝘷𝘦𝘯 𝘵𝘩𝘦 𝘶𝘴𝘦𝘳 𝘩𝘢𝘴 𝘢 𝘣𝘢𝘭𝘢𝘯𝘤𝘦 𝘰𝘧 $100 𝘞𝘩𝘦𝘯 𝘵𝘩𝘦𝘺 𝘢𝘵𝘵𝘦𝘮𝘱𝘵 𝘵𝘰 𝘴𝘦𝘯𝘥 $150 𝘛𝘩𝘦𝘯 𝘵𝘩𝘦𝘺 𝘴𝘩𝘰𝘶𝘭𝘥 𝘴𝘦𝘦 𝘢𝘯 "𝘐𝘯𝘴𝘶𝘧𝘧𝘪𝘤𝘪𝘦𝘯𝘵 𝘧𝘶𝘯𝘥𝘴" 𝘦𝘳𝘳𝘰𝘳 As a PM, involving your team in BDD can dramatically improve requirements clarity and reduce rework! ⁉️ Which testing approach do you currently use in your projects?

1. Functional Testing: The Foundation a. Unit Testing: - Isolating individual code units to ensure they work as expected. - Analogous to testing each brick before building a wall. b. Integration Testing: - Verifying how different modules work together. - Similar to testing how the bricks fit into the wall. c. System Testing: - Putting it all together, ensuring the entire system functions as designed. - Comparable to testing the whole building for stability and functionality. d. Acceptance Testing: - The final hurdle where users or stakeholders confirm the software meets their needs. - Think of it as the grand opening ceremony for your building. 2. Non-Functional Testing: Beyond the Basics a. Performance Testing: - Assessing speed, responsiveness, and scalability under different loads. - Imagine testing how many people your building can safely accommodate. b. Security Testing: - Identifying and mitigating vulnerabilities to protect against cyberattacks. - Similar to installing security systems and testing their effectiveness. c. Usability Testing: - Evaluating how easy and intuitive the software is to use. - Comparable to testing how user-friendly your building is for navigation and accessibility. 3. Other Testing Avenues: The Specialized Crew a. Regression Testing: - Ensuring new changes haven't broken existing functionality. - Imagine checking your building for cracks after renovations. b. Smoke Testing: - A quick sanity check to ensure basic functionality before further testing. - Think of turning on the lights and checking for basic systems functionality before a deeper inspection. c. Exploratory Testing: - Unstructured, creative testing to uncover unexpected issues. - Similar to a detective searching for hidden clues in your building.
