🧑‍🔬 Manual Testing
Definition: Manual testing involves human testers executing test cases without the assistance of automation tools. Testers interact with the software as end-users to identify defects and ensure functionality aligns with requirements.​
Key Characteristics:
- Human-Centric: Relies on the tester’s intuition and experience to uncover issues, especially in user interfaces and user experience.​
- Flexible: Allows for on-the-fly test case modifications and exploratory testing.​
- No Programming Required: Testers do not need to write code, making it accessible for non-technical personnel.​
Ideal Use Cases:
- Exploratory Testing​Katalon AI
- Usability Testing​Reddit+2GeeksforGeeks+2Katalon AI+2
- Ad-hoc Testing​Katalon AI
- Short-term projects with rapidly changing requirements​
Limitations:
- Time-consuming and less efficient for repetitive tasks.​
- Prone to human error.​
- Limited test coverage compared to automation.​
🤖 Automation Testing
Definition: Automation testing utilizes scripts and tools to execute test cases, comparing actual outcomes with expected results. It’s designed to handle repetitive tasks efficiently and consistently.​
Key Characteristics:
- Tool-Driven: Employs frameworks like Selenium, JUnit, or TestNG to automate test execution.​Perfecto
- High Efficiency: Executes large volumes of tests quickly, ideal for regression and performance testing.​TestRail
- Requires Programming Knowledge: Testers need to write and maintain test scripts.​
Ideal Use Cases:
- Regression Testing​
- Load and Performance Testing​Reddit+8BrowserStack+8TestRail+8
- Projects with stable requirements and long-term maintenance​GeeksforGeeks+1BrowserStack+1
Limitations:
- High initial setup cost and time investment.​
- Less effective for testing user experience aspects.​
- Requires technical expertise to develop and maintain test scripts.​Testsigma
