Software testing is an essential component of any project’s success.
Companies boost user experience and improve the performance of their apps by testing them.
Manual and automated testing are the two basic ways of testing.
Both have been panned and praised over the internet, so picking the right one for your project can be difficult.
In this piece, we’ll go over the differences between them, their benefits and drawbacks, and how developers can use them to their advantage.

Manual testing of mobile applications
The most basic sort of testing is manual testing, which relies solely on human supervision.
Manual app testing has been losing ground to automated app testing in recent years, with the latter proving to be faster and more efficient. However, it may be premature to declare manual testing extinct, as it offers its own set of benefits.
This method assumes that someone on the team will execute all tests from start to finish without the use of automation tools, extensions, or scripts.
While manual testing is inconvenient and time-consuming, it is unavoidable.
Before tests can be automated, any program must be manually tested.
The good news is that, whereas automated tests frequently necessitate the hiring of an automation engineer, manual tests can be done by everyone in the team who has a good understanding of the requirements of the app.
As a result, here are some reasons why manual mobile testing is still important and effective in the mobile app development industry:
1. Precision and accuracy
Manual mobile testing provides the user with complete control over each and every test, allowing them to figure out exactly what is going on when an issue appears.
Manual testing methods for mobile applications allow testers to test functionality in real-time without having to worry about the extra time and layers that scripts contribute.
It offers a lot of flexibility for effectively measuring the user experience in a timely manner.
2. Besides functional problems, also user experience problems can be detected
The only way to get a true user experience is to have a user participate in the testing.
Manual mobile testing allows testers to act like real users, relying on their instincts and prior experience with mobile app usage to approach an app’s functionality in a realistic manner. Many converts to manual mobile application testing have expressed how startling it is each time when they observe a user interacting with an app in a way that developers could never have predicted.
As a result, manual testers can easily tell whether an app was tested manually or via test automation only; the awkward bugs you hear about that cause app crashes are all too often the result of automated oversight that can never fully prepare for what a human will do when the app is in their hands.
3. When you need it the most, a deeper grasp of bugs will come in handy
Manual testing for mobile applications is perfect for giving testers a mental picture of where and when a defect is happening, so they don’t have to dig through data and try to wrap their heads around the point of mistake in an automated testing cycle.
This allows testers to communicate more effectively with development teams about how to troubleshoot the app.
1. Human mistake is a possibility
One of the main reasons testers turn to automation is to eliminate human mistakes that occur while testing manually.
Automated scripts, of course, are also authored by humans and, as a result, are also not immune to failure. Once the script is fixed, however, it is going to do exactly the same thing, again and again.
Manual mobile application testing, on the other hand, necessitates a constantly high degree of concentration throughout each session, leaving even more possibilities for error.
2. Human resources are in short supply
To do some manual load testing for example, you would need quite a few testers to use the system simultaneously. Unfortunately, there aren’t many companies capable of providing a team big enough to test the load of a high-traffic mobile app. Automation is handier this way, as one specialist can account for dozens of simultaneous tests.
3. Test automation might be cheaper than manual testing
This aspect is fully budget-dependent and will differ from team to team. But generally speaking, test automation has become more affordable.
For many years there have been free (and open source) tools out there promising test automation for almost zero costs.
Now a days we know that it’s not true. Also open source costs a lot of money, for setup and maintenance.
The good news is: The nocode / lowcode trend has also hit the test automation market. There are tools such as Repeato which offer a free plan and get you going in a very short amount of time.
4. Testers’ productivity is low
Finally, manual testing isn’t the most efficient use of manpower.
QA specialists are obliged to manually examine even the most basic workflows instead of making plans, checking reports, and so on — a process that can occupy days of one’s productive time. Repeated execution of the same tasks can drain your testers, physically and emotionally and will cause them to more easily make mistakes.
When Should You Use Manual App Testing?
Is a term used to describe the process of testing something new. For this scenario, mobile apps require human testing, there is just no other way.
Knowledge, analysis, experience, intuition, and imagination are all necessary for exploratory testing.
Testing for usability
Without manual testing, it’s impossible to tell if a mobile app is user-friendly.
In determining how efficient and handy a product is, human observation is the most significant component.
This is an ad hoc style of testing that relies only on the tester’s knowledge and intuition.
Your product is only as good as its performance from the perspective of your users, which is why QA is so important for mobile app success.
While thorough mobile app testing is repeatable, it’s good to have some variety in the tests you run.
Manual testing is required for researching use cases that aren’t immediately evident. Automated mobile app testing is suitable for executing many, time-consuming tests.
Whatever type of mobile app testing you pick, planning ahead of time for what has to be tested is essential before development begins.
Who Requires Manual App Testing?
It might be difficult for project managers to distinguish between manual and automated testing.
Choosing the right testing approach will be impacted by different factors: the project’s size and scope, the deadline, the team’s size and skill level, and so on.
To assist in the decision-making process, below is a list of scenarios in which QA experts prefer manual testing:
- Small-scale initiatives. The suite of tools and script upkeep are costly for small businesses, and setting up the environment takes time. When an app just has a few functionalities, it makes sense to manually test them.
- Very dynamic apps. Manual mobile testing is the ideal solution if your app has a dynamically changing user interface or long workflows, as automating tests of very complex use cases takes a lot of time.
- Types of tests that cannot be automated such as UX testing
The Importance of Mobile App Testing Automation
Automated testing is a method of finding problems and evaluating a product’s performance using a tool.
The tool needs to first be instructed on which actions should be executed and which results are expected. This is the hard part. But as soon as that’s done, the test scripts can be run an endless number of times without any further time investment by the QA person.
Automated app testing is especially necessary as soon as an app grows so complex that manual app testing costs would surpass the costs of automating the work.
Performing tests on a continuous basis
Automated testing is ideal for short release cycles, each requiring a complete software test before the release.
Costs for running tests will decrease over time
While the initial time investment is high, overall costs will decrease over time, because automation is cheap compared to manual testing as soon as it’s set up.
Test scripts can be reused for multiple projects to save time and ensure faster market delivery.
Because a QA specialist can be certain that the same set of actions will be done throughout each execution, automation improves test reliability.
Opportunities for parallel testing
A QA specialist can conduct dozens of tests on a variety of systems at the same time using automated testing. Manually, nobody would be able to do that much multitasking.
Maintenance can be time-consuming
Keeping automated tests updated can be difficult, depending on how much the application under test changes over time.
Manual testers can be efficiently instructed to test an additional use case just once or just for a short amount of time. This would be much more expensive to do with automated testing.
When testing small features, it’s slow and inefficient
If a developer wishes to evaluate the performance of a small-scale feature, writing an automated script is a waste of time.
When Should You Use Automated App Testing?
Because of the frequent code changes, automated testing is ideal for regression testing. A manual tester’s life might be made much more difficult by frequent code changes.
Execution that is repeated
Automated testing is ideal for repetitive and time-consuming operations.
Automation is useful when testing the speed and performance of a mobile app, maybe even against thousands of concurrent users.
Automated testing can save money and resources in large projects.
Manual vs. Automated Testing Checklist
We’ve created a checklist to assist you in deciding which form of QA testing to use:
- Is your project still in the early stages of development?
- Have you ever conducted software testing?
- Do you need to cut down on the time you spend doing regression testing after making changes?
- Do you have any recurring tasks?
- Do you want to shorten the time it takes to perform functional tests such as correctness, interoperability, compliance, security, and stability?
- Do you require performance testing at maximum load and capacity?
- Do you conduct ad-hoc testing without a documented test case?
- Is this a long-term project?
- Do you need to test the project’s aesthetic aspects or user experience in general?
