# Quality Assurance & Software Testing ๐Ÿงช > Making sure apps actually *work* before anyone else uses them โ€” the people who catch > bugs, break things on purpose, and protect users from frustration. [โ† Back to all career paths](README.md) --- ## What is it? Before an app reaches millions of phones, someone has to check: *Does the login work? What happens if I enter the wrong password? Does it break on a small screen?* That's **Quality Assurance (QA)**. QA testers are the **guardians of quality**. They try to break the app *on purpose* โ€” in a helpful way โ€” so that bugs are found and fixed **before** users ever see them. There are two main styles: - **Manual testing** โ€” a human carefully clicks through the app looking for problems. - **Automated testing** โ€” writing code that tests the app automatically, over and over. > ๐Ÿงช Think of a QA tester like a taste-tester in a kitchen: they check everything is right > *before* the meal reaches the customer. --- ## What would I actually do? - Try every button and screen to make sure it works as expected - Deliberately do "wrong" things (blank forms, huge numbers, bad passwords) to see what breaks - Write clear **bug reports** so developers can understand and fix the problem - Test the app on different phones, browsers, and screen sizes - Later: write **automated tests** so checks run by themselves --- ## Is this me? โœ… You might love QA & testing if you: - Have a sharp eye for detail and notice when something is "off" - Are curious and love asking *"but what if I do this...?"* - Are patient, organised, and thorough - Like being the person who makes things better for everyone > ๐Ÿ’ก QA is one of the **friendliest ways into tech** โ€” you can start with no coding at all, > then add automation skills over time. --- ## Skills to build (in order) 1. **Attention to detail** โ€” the core superpower of every great tester 2. **Testing basics** โ€” test cases, bug reports, "expected vs actual" results 3. **Clear writing** โ€” a good bug report is easy to read and repeat 4. **A little programming** โ€” **Python** or **JavaScript** for automation later 5. **Automation tools** โ€” like **Selenium** (web) or **Playwright** โ€” when you're ready 6. **Basic Git & GitHub** โ€” to work alongside developers > ๐Ÿข You can become a solid **manual tester** before writing a single line of code. --- ## Free resources - **[Test Automation University](https://testautomationu.applitools.com/)** โ€” free, high-quality QA courses - **[Ministry of Testing (Dojo)](https://www.ministryoftesting.com/dojo)** โ€” friendly testing community & lessons - **[Software Testing on freeCodeCamp](https://www.youtube.com/@freecodecamp)** โ€” free full tutorials - **[Guru99 Testing tutorials](https://www.guru99.com/software-testing.html)** โ€” clear beginner guides - **[Playwright docs](https://playwright.dev/)** โ€” modern, beginner-friendly test automation - **[The Definitive Bug Report guide](https://www.softwaretestinghelp.com/how-to-write-good-bug-report/)** --- ## Starter projects ๐Ÿš€ You can start testing **today** โ€” no special setup needed. 1. **Bug hunt** โ€” pick any app you use and find 5 things that could be clearer or that break. Write each up as a bug report. 2. **Write a test plan** โ€” list every step to test a login screen (right password, wrong password, blank fields). 3. **Break a classmate's project** โ€” test a friend's CodePen or Scratch project and report what breaks. 4. **Cross-device check** โ€” open a website on a phone and a laptop; note what looks different or wrong. 5. **First automated test** โ€” follow a Playwright "hello world" tutorial to make a test run by itself. --- ## Your first steps (do these this week) - [ ] Pick an app and write your **first bug report** (steps, what you expected, what happened) - [ ] Write a test plan for a login page โ€” list at least 5 things to check - [ ] Test a classmate's project and share your findings kindly - [ ] Watch one "What is software testing?" beginner video - [ ] Learn the phrase **"expected result vs actual result"** โ€” it's the heart of testing - [ ] Explore one free lesson on Test Automation University --- ## Roles this can grow into QA Tester โ€ข QA Analyst โ€ข Test Automation Engineer โ€ข Software Development Engineer in Test (SDET) โ€ข QA Lead โ€ข Quality Engineer > ๐Ÿ’ก Every app you love was tested by someone like this. QA is a **welcoming entry point** into > tech โ€” and automation testers are in high demand and well paid.
