Which testing method manual or automated should you adopt and when

Despite being a diverse field, software testing may be largely divided into two types: manual testing and automated testing.

Both manual testing and automated testing have advantages and drawbacks. Knowing the distinction and when to employ each is important for getting the greatest results.

As the name implies, manual testing involves carrying out test cases manually without the aid of any tools or scripts. In contrast, test cases in automated testing are carried out with the aid of tools, scripts, and software.

Every successful software project includes testing. The project needs, budget, timeframe, level of skill, and suitability are just a few of the variables that affect which style of testing—manual or automated—is used.

We hope that this comparison of automated vs. manual testing will aid you in making an informed choice. The current tendency is toward automation, and this trend extends to software and internet testing as well.

But when is using automated testing superior to manual testing? Is manual still preferable in some circumstances? Let’s look at it in this article.

2. Automation Testing

To automate test execution in automated software testing, testers create code or test scripts. The development of test scripts and software validation are done by testers using the necessary automation tools. Reducing the amount of time, it takes to finish running tests is the aim.

For the only purpose of comparing the actual results with the anticipated results, automated testing fully depends on the pre-scripted test that runs automatically. This aids in the tester’s assessment of whether or not an application operates as anticipated.

Without the involvement of a manual tester, you can carry out repetitive tasks and regression tests using automated testing. Despite the fact that all procedures are automated, the first testing scripts for automation still require some manual work.

3. Manual Testing

Manual testing is software testing in which tests are performed manually by a QA Analyst. It is used to find bugs in software that is still in development.

When performing manual testing, the tester verifies all of the programme or application’s critical components. Without using any automated software testing tools, the software testers carry out the test cases and produce the test reports in this procedure.

It aids in detecting defects in software systems and is a traditional method for all testing kinds. The process of software testing is often carried out by an experienced tester.

4. Advantages and Disadvantages of Manual Testing

4.1 Advantages of manual testing

Obtain immediate and precise visual feedback.
Cost-effective as you don’t have to spend money on automation tools and processes.
The manual component always benefits from human judgement and intuition.
An automation test would need to be coded, which may take time while testing a simple change. While you could perform a manual test immediately.

4.2 Disadvantages of manual testing

Since it is carried out by a human, it is a less dependable testing procedure. As a result, faults and blunders are always possible.
It is not possible to reuse the manual test because the manual testing method cannot be recorded.
A longer period of time may be needed for the software testing phase because several activities in this testing approach are challenging to complete manually.

5. Advantages and Disadvantages of Automation Testing

5.1 Advantages of Automation Testing

Comparatively speaking, automated testing aids in finding more bugs than human testers.
You may have a quick and effective approach since the majority of the testing process is automated.
A process of automation can be recorded. This enables you to repeat and carry out the same testing procedures.
In contrast to manual testing, which involves humans, automated testing is carried out using software tools, so it is human- and fatigue-free.
Since it delivers quick & precise testing results, it can readily enhance productivity.
Numerous applications are supported by automated testing.
Automation testing tools can boost testing coverage; always remember to examine even the smallest unit.

5.2 Disadvantages of Automation Testing

Without a human element, it might be challenging to get understanding of your user interface’s visual elements, such as colours, fonts, sizes, contrast, and button sizes.
The cost of the testing project may rise due to the potential expense of the automation testing technologies.
Testing automation software is not yet error-free. Each automation technology has constraints that limit the breadth of automation.
Another significant challenge with automated testing is script debugging. It costs money to maintain tests.

6. When to Use Automation Testing?

Overall, automated testing is a good way to save time. In some circumstances, automated testing should be mandatory and manual testing should be entirely disregarded.

Let’s look at a few of these instances:

6.1 For Tasks That Take a Long Time

Handling time-consuming jobs is one of the best uses for automated testing. You must confirm the application continues to function properly when your development team makes updates or modifications.

You can utilise automated regression tests to save time and avoid repeatedly verifying every aspect of the application’s functionality.

6.2 For Repeated Activities

For repetitive processes that are regularly repeated within the programme, automated testing is ideal.

The adaptability of automated tests might be a wonderful time-saving solution if you discover that the same features are frequently introduced, or the same processes are carried out repeatedly.

6.3 For Functional Testing

Another excellent moment to use automated testing is during functional testing. The real performance of an application’s functional requirements can be rapidly and simply determined.

Accuracy, interoperability, compliance, security, and suitability are typically factors that are considered.

6.4 For Performance and Load Testing

Use automated testing if you need to check the application’s load or performance. There is truly no manual substitute for appropriately testing load and performance.

Automated tests are capable of simulating hundreds or even thousands of concurrent users.

6.5 Innovative GUI Testing

Automating these can save a lot of time when performing sophisticated Graphical User Interface (GUI) testing. Automated GUI testing identifies and monitors behavior variations among various web browsers, operating systems, gadgets, etc.

Additionally, regression issues can be successfully found faster by automated GUI testing.

7. When to use Manual Testing

7.1 If flexibility is required

Testing done manually gives testers more operational flexibility, even though it isn’t necessarily as accurate as testing done automatically. This frequently implies using the same code and scripts repeatedly because automated testing is intrinsically useful for repetitive scenarios.

7.2 During the active phase of short-term projects

When working on short-term initiatives, planning and investment are often unnecessary. The initial cost of automating a project like this can be excessive given the potential return on investment and value of the result. Manual testing would be more cost-effective and profitable in this case overall.

7.3 Whenever usability is evaluated.

The usability of an application can makes a big difference in whether it succeeds or fails. To ensure there are no problems, this goes much beyond simply performing automated tests. Computers cannot offer the same kind of feedback that a human user would when utilizing an app since they execute preprogrammed activities rather than thinking independently. Automated tests, for instance, can quickly identify coding flaws, but they cannot predict how users will interact with a particular feature or how well users will be able to use the application.

A key aspect in determining whether other users embrace the app is whether consumers discover that a tool in the software does not function as they need it to. This kind of information would be produced via manual testing.

8. Conclusion

Software and website testing do not have a one-size-fits-all solution that works universally. While automated testing can often save significant amounts of time and resources compared to manual testing, there are situations where manual testing is the preferred approach. It’s important to find a balance between the two and determine which technique is most appropriate for a given scenario to save time, money, and prevent future issues.

Both automated and manual testing have their advantages and disadvantages, and it’s essential to acknowledge that not everything can be automated, no matter how efficient or thorough automated testing may be. Manual testing remains an integral part of software development when certain processes cannot be automated.
