Manual testing: Ensuring quality software
Manual testing is a crucial part of the software development lifecycle. It involves systematically checking software for bugs, usability issues, and deviations from requirements without the use of automated tools. A skilled manual tester meticulously explores the software, mimicking real-user scenarios to identify potential problems before they reach the end-user. This hands-on approach allows for nuanced evaluation of the user experience, catching subtle issues that automated tests might miss.
What to look for in a freelance manual tester
When hiring a freelance manual tester, look for a combination of technical skills, analytical thinking, and excellent communication. Essential qualities include:
- Strong understanding of software testing methodologies (e.g., agile, waterfall)
- Experience with various testing types (e.g., functional, usability, performance)
- Proficiency in creating detailed test cases and documenting results
- Excellent communication and reporting skills
- Ability to work independently and as part of a team
Main expertise areas
Different manual testers specialise in different areas. When briefing a freelancer, consider these key areas of expertise:
- Web application testing: Evaluating websites and web applications across different browsers and devices.
- Mobile application testing: Testing apps on various mobile platforms (iOS, Android) and devices.
- Usability testing: Assessing the user-friendliness and overall user experience of the software.
- Performance testing: Evaluating the software's responsiveness and stability under different load conditions (though this can also be automated).
- Accessibility testing: Ensuring the software is usable by people with disabilities.
Relevant interview questions
Here are some questions to ask potential freelance manual testers:
- Describe your experience with different testing methodologies.

Real-world examples
Consider these examples of how manual testing is applied:
- E-commerce platform: A tester manually checks the checkout process, ensuring all payment gateways function correctly and that order confirmations are sent successfully. They also verify the responsiveness of the site on different devices.
- Mobile game: A tester plays through various levels of a mobile game, looking for glitches, performance issues, and inconsistencies in gameplay. They also test the game's compatibility with different operating systems and screen sizes.
- SaaS application: A tester explores all features of a software-as-a-service application, verifying data integrity, user permissions, and integration with other systems. They also perform usability testing to ensure the application is intuitive and easy to navigate.
