8 Justifications for Manual Testing's Persistence

We've all encountered one or more bugs in the many programs we use on a daily basis, and we've previously written an article about the value of software testing.

There are many different methods for testing software, but they may typically be split into manual and automated testing. We've written a lot of articles about automated testing, leading one to believe that everything can be automated and that automation has no restrictions. Although there are more and more tools and frameworks for test automation, not all tasks should or can be automated. Sometimes it is more advantageous and less expensive to stay with manual testing. This post will go over eight reasons why manual testing is still essential and why it might be useful.

1. Time

Even if automated tests themselves run more quickly and with less intervention from the tester, setting up the automation infrastructure might take some time. In some circumstances, manual testing might be more expedient than automated testing. Early in the project, when it is less likely to take a lot of time, setting up the automated environment and automated tests is simpler. The automation environment and test setup, on the other hand, will take up more time and resources if the project is really complicated and has a lot of interrelated components. In some circumstances, the project's complexity may make it difficult or prohibitively expensive to develop an automated environment and automated testing for it.

2. Human contact.

Additionally, computerized exams lack human sensitivities. After all, testing and value checks are performed by the computer. An app's visual appeal and the proper operation of its functionality are equally important to end users. Most of the time, automated tests would verify that a text label's value was shown on the screen, for example, but not its exact location. In these circumstances, manual testing is practical since it is simple to confirm the element's visual appearance. If the user interface is complicated, testing it manually is far quicker and less expensive than automating everything.

3. You require expertise

The output of such testing may be deceptive, making these activities ineffective if automated tests are created improperly and without adhering to standard practices. You should appoint qualified professionals to the role of test automation design and execution, according to our own experience of working on several test automation projects. When creating test environments, writing tests, and maintaining the code, these engineers will adhere to best practices. Daily maintenance and inspection are required for automated testing.

4. Safety

You should carefully consider each permission required for the test execution in complicated projects. The systems and environments to which testers have access may be limited in some projects by test automation engineers, who may not have complete access to the system. It is crucial to consider whether utilizing automated testing at all is worthwhile in such circumstances. On systems where you don't have the proper access level, you can't automate testing.

5. Interventional testing

Interventional testing is a sort of testing in which testers examine the system as they go along without beforehand creating test cases. It might assist the tester in locating significant problems fast, assisting in the development of a product that is genuinely required. Exploratory testing is not compatible with automated testing, despite the fact that automated tests are made up of test scenarios created by a test engineer. The machine will only check the items that are written to be checked and confirmed – nothing more and nothing less – and these situations are not customizable.

6. Not all processes can be automated

Both recommending and being able to automate everything are not viable options. It is not realistic to automate the process if you have a mobile product and need to confirm that it functions on various devices, screen sizes, operating systems, and manufacturers. Many older phones also don't allow automation. There may be instances where a particular platform or device lacks automation tools.

7. Constancy

Additionally, let's say that an application is still being built and is not yet in a particularly stable state. In such instances, there would be little use in investing time and money in developing an automated environment and automated tests as they would need to be continuously updated in response to changes in the application's version. To preserve intended results, test cases and scenarios must be reviewed regardless, but when an application is unstable, the results of automated tests are more likely to be inaccurate. Automated testing will also be objective and stable if the application is stable.

8. Requirements analysis validation

Not to mention, it is hard to validate user requirements without manually running the tests. In this situation, it is necessary to examine and confirm functionality in accordance with the provided documentation. This can only be carried out by a test engineer who first runs a manual test to confirm the operation of newly added features or modifications. Immediate creation of the automated test may result in problems. Test scenarios are developed after manual testing of the functionality that has been described. Defects need to be corrected before functioning can be objectively tested. Automated testing can only be made after that.

In conclusion, both human and automated testing techniques have advantages and disadvantages. And it is up to a test engineer to decide which approach and at which stage will best meet the demands of the project.
