Website development cannot exist without testing. QA engineers are the reliable guards of website quality and adherence to requirements. So one of the things you can expect from working with a web development company is that they also have a strong QA team. Among numerous testing types, we primarily distinguish between manual and automated testing. Which of them is better and why? See the answers in our blog post.
Manual testing vs automated testing: who wins?
Manual testing is the one performed manually by humans, while automated testing means the use of testing tools, scripts, and software. At first glance you may assume that manual testing was the first to appear, and then manual tasks just got automated.
However, according to the famous QA James Bach, test automation was around from the first day of computing. Programmers tested their products themselves using software, and the testing process was not very much different from debugging. And as projects were getting larger and more complicated, the concept of a dedicated testers appeared.
Both manual and automation testing have their own advantages, so let’s take a brief look at them.
Some advantages of automated testing
- Higher accuracy and reliability without the risk of human error.
- 24/7 operation without human supervision
- The chance to repeatedly reuse the once written tests
- Extremely high testing speed
- Large coverage of test cases (including browsers, devices, screen resolutions, operating systems etc.)
- Best options for performance, load and stress testing, which checks how your site will perform in with extreme loads (for example, thousands of users at the same moment)
- Best options for regression testing in case of frequent code changes to see if they have not broken anything
- Ideal for repeated or complex tasks, or ones involving multiple platforms or configurations
Some advantages of manual testing
- Unmatched opportunities in usability testing (because only humans can access user-friendliness from a human point of view)
- Lower testing costs per hour of QA engineer work
- The chance to start testing right away without time for writing automated tests
- Best fit for exploratory testing, often described as simultaneous test design and test execution, which lets QAs show maximum creativity
- Best fit for Ad-hoc testing (also referred to as random testing or monkey testing) that has no plan and can result in unexpected insights
- Best price/quality ratio for one-time or simple testing tasks
Combining manual and automated testing
As we see, some benefits of one type of testing mirrors the drawbacks of the other. But is this really a competition? On the contrary, manual and automated testing can be combined according to the project needs and budget. That’s where the puzzle fits.
A good QA team can identify which tasks will benefit from automation and where human eyes and hands remain the best “tool”. Then choices will be based on the testing area (usability, performance, regression testing, and so on), the complexity, repeatedness, and importance of the testing task, your business priorities, and your budget. With this approach, your project will be covered from all possible angles.
And that’s exactly what you will find at Drudesk. Our QA engineers have solid experience with manual and automated testing, the profound understanding of the Agile methodology, the ability to set priorities, and so on. Our manual and automation QA engineers love new frameworks and technologies, and cooperate with each other perfectly.
