What is Manual Testing?
This is undoubtedly the classical way of testing. In manual testing, all tests are performed by a human specialist. He or she executes the test cases, checks all the essential features to find bugs, and creates the report without using any testing software. That is why only an experienced QA engineer should conduct the software testing process.
Advantages of Manual Testing:
- A tester could do his or her job manually on the fly, especially while testing a small feature;
- Sometimes nothing beats classic human intuition and judgment;
- No need to spend money for specialized automation tools. This makes manual testing more cost-effective;
- With manual testing, you can get accurate and fast visual feedback.
Disadvantages of Manual Testing:
- Certain tasks are simply impossible/difficult to be completed by humans;
- Manual testing is a more time-consuming approach as it takes up human resources
- It is difficult to record the manual testing process, which makes it difficult to accurately recreate or reuse it
- Manual testing is always prone to errors due to the presence of human element. This puts the reliability of this method into question.
Automated Testing Vs. Manual Testing: When to Use?
Automated testing works best in the following scenarios:
- Performance testing. For example, it can be used to test the website’s performance during moderate, heavy and peak demand;
- Repeated execution. It is best to automate this kind of testing;
- Load testing. This approach is the only way to execute this kind of testing effectively;
- Regression testing. Automation allows to run the regressions on a timely basis and taking into account changes in code.
Manual testing is the best solution in the following scenarios:
- Ad-hoc testing. Although there is no optimal method for this scenario. Thus, this choice is up to the tester.
- Usability testing. In this case, you need to evaluate how convenient, efficient, and user-friendly your product is for users. So this method is undoubtedly preferable;
- Exploratory testing. In order to execute the testing process, human intuition and creativity are required.
