What is manual testing?
Manual testing is testing that is performed without the help of any tool (automation). In this testing, the tester writes test cases for the code, tests the software and gives a final report about the software. Manual testing is time-consuming testing because it is done by humans and there is the possibility of human error.
- Conduct manual testing to find bugs in developed software applications.
- Testers check all the basic functionality of the application.
- Testers execute test cases and generate test reports
- , without any help from automated tools.
- Testing is conducted by experienced testers and the testing process is completed.
When to do manual testing?
Manual testing should be performed under the following circumstances:
- Need flexibility:With manual testing, QA can test quickly and provide quick feedback.
- Short-term projects:It is not recommended to invest more money and effort in setting up short-term projects focusing on small functions, because such a setup will require huge energy and funds, for such Too high for a small project.
- When testing end-user usability:If the application provides a satisfying user journey, humans can use their sensitivities to understand the application's behavior. No machine can do this task as well as a human.
Benefits of manual testing
- Easy hiring:In manual testing, anyone can test, thus facilitating easy hiring.
- Quick feedback
- :Manual testing helps provide fast and accurate feedback.
- Multi-purpose:Manua test cases can be applied to many test cases.
- Flexible:Manual testing is flexible because it can easily adapt to user interface changes.
- Cheaper:Manual testing is cheaper because there is no need to automatetools and processes
- Spend on your budget.

Limitations of manual testing
- Not all defects detected:In manual cases, 100%test coverage cannot be guaranteed
- , so some defects may not be detected.
- High specialization:Although manual testing can be performed by anyone, some complex situations require a high degree of specialization.
- A lot of time:Manual testing requires a lot of time. It requires a lot of time to manually develop test cases in order to cover and test all functionality.
- Unable to record:The manual testing process cannot be recorded, so manual test cases cannot be reused.
- Not very reliable:Manual testing is not very reliable because it is conducted by humans and all test cases are designed by humans, so there is a possibility of human error.
What is automated testing?
Automated testing is a type of testing where we execute the tests with the help of tools (automation). It is faster than manual testing as it is done with some automated tools. There is no possibility of human error.
- It relies entirely on automatically runpre-scripted tests
- , to compare actual results with expected results.
- Automated testing helps testers determine whether an application performs as expected.
- It allows for repetitive tasks and regression testing
- 。
- Automation requires manual creation of initialtest script
- 。
When to perform automated testing?
- In this scenario, automated testing is the best choice. For example, in the case of regression testing, it must be performed regularly to ensure that newly added code does not break the existing functionality of the software.
- When human resources are scarce:Automated testing is feasible, and when there are only a limited number of dedicated testers, automated testing is cut off at Date
- The best choice for performing testing within.
Benefits of automated testing
- Find more bugs:Automated testing helps find more bugs and defects in software.
- Reduce regression testing time:Automated testing is suitable for regression testing because the tests can be repeated at regular intervals.
- Processes can be recorded:This is one of the benefits of using automated testing, as these tests can be recorded, allowing for test reuse.
- Fatigue-free:As an automated test, usesoftware tools
- Tests are performed so there is no fatigue or tiring factor in manual testing.
- Increase test coverage:Automated testing helps in increasing test coverage as using tools for testing helps ensure that even the smallest unit is not left untested.
Limitations of automated testing
- Difficulty in inspecting visual elements:In automated testing, it is difficult to gain insight into visual elements such as color, font size, font type, button size, etc. without human intervention.
- High cost:Automated testing is expensive to implement because testing requires tools, thus increasingproject budget
- the cost of.
- High test maintenance costs:In automated testing, test maintenance costs are high.
- Non-false proof:Automated testing also has some limitations, and errors in automated testing may lead to errors and omissions.
- Trained staff required:In order to conduct automated testing, trained staff with knowledge of programming languages and testing are required.
The difference between manual testing and automated testing
| parameter | Manual testing |
|---|
| automated test | ||
|---|---|---|
| definition | In manual testing, test cases are executed by testers. | In automated testing, test cases are executed by software tools. |
| processing time | Manual testing is very time consuming. | Automated testing is faster than manual testing. |
| Resource requirements | Manual testing |
| Take up human resources. | Automated testing requires automation tools and trained staff. | |
| exploratory testing | Exploratory testing can be done in manual testing. | exploratory testing |
| This is not possible in automated testing. | ||
| Framework requirements | Manual testing does not use frameworks. | Automated testing uses frameworks such as Data Drive and Keyword. |
| reliability | Manual testing is unreliable due to the possibility of manual errors. | Automated testing is more reliable due to the use of automation tools and scripts. |
| invest | In manual testing, investment in human resources is required. | In automated testing, tools andautomation engineers are required |
| Make an investment. | ||
| Test result availability | In manual testing, the test results are recorded in an Excel sheet and are therefore not readily available. | In automated testing, test results are readily available to all stakeholders in the automation tool’s dashboard. |
| human intervention | Manual testing allows human observation, so it is useful in developing user-friendly systems. | Automated testing is performed by automated tools and scripts and therefore does not involve guarantees of user-friendliness. |
| Performance Testing |
| Performance testing is not possible with manual testing. | Performance testing, such as load testing, stress testing, Peak testing |
| wait. | ||
| Batch testing | In manual testing, batch testing is not possible. | You canBatch processing |
| Multiple tests for fast execution. | ||
| Programming knowledge | Manual testing requires no programming knowledge. | In automated testing, programming knowledge is a must since using the tools requires well-trained staff. |
| document | In manual testing, there is no documentation. | In automated testing, documentation serves as a training resource for new developers. He/she can view unit test cases and quickly understandcode base |
| 。 | |
| When to use? | Manual testing can be used for exploratory testing,usability testing |
| and interim testing. | Automated testing is suitable for regression testing, load testing and performance testing. |
