Software testing is an essential step in the software development lifecycle (SDLC) that aims to check that the development team constructed the software correctly (according to the specification) and that the created software fits the customer needs. Software quality assurance is a vast field that encompasses numerous techniques, strategies, and technologies. So, while the overall goal of QA is to be unified, it is necessary to segment this process into more particular domains such as human vs. automation testing.
They both have advantages and disadvantages and can improve any software development project if used properly. But what exactly is the distinction between human and automated testing? In this post, we will look at how manual and automation testing function, what their benefits and drawbacks are, and when it is better to use either.
When using manual software testing
One of the two basic types of testing is manual software testing, in which test cases are conducted without the use of automation tools or scripts. Manual testers ensure that software functionality and design are proper by creating test plans, generating test cases, manually implementing them, and reporting on test case execution. As a result, they detect obvious and hidden software flaws, which are differences between meant and actual results. And, while there are some situations where manual testing is more appropriate, many people would argue that automation is far more advantageous and generally applicable. They believe that the day will come when automation will replace manual testing.
The Benefits of Manual Testing
Every organisation that performs automated testing also performs some manual testing. These are the most strong arguments why this is the case now and why it is unlikely to change in the near future.
The speed and adaptability
Teams in the modern day must be adaptable. An IT team that works in an agile environment has higher success rates in software development, as well as improved quality and speed to market, as well as increased motivation and productivity. At the same time, one must be able to respond quickly to even minor changes in requirements.
Human response
Automated testing is not without problems. It is well knowledge that application code can have defects, but test automation code can also be flawed. As a result, if a QA automation engineer develops tests that contain defects, the team will receive false positives.
Visible feedback
Manual testing verifies that the visual presentation layer correctly translates commands received from the application layer. As a result, manual testing is suitable for UI acceptance testing. They are a better fit when testing visual components of a page, such as how it looks after some action is taken and whether or not these visual changes are unclear.
The disadvantages of manual software testing
Errors are more likely to occur
Manual testing is less accurate than automated testing. The human touch that allows it to successfully complete UI acceptance testing at the same time makes it less trustworthy at times and more prone to error. As a result, some flaws may go undiscovered, negatively impacting end-user experience. This is especially true for tests that are repeated. They take more time and are therefore more difficult to carry out manually. If such tests are discovered on the project, it is time to automate. Otherwise, the team may find itself in a risky situation.
The process’s time-consuming nature
Although the implementation of automated tests takes a significant amount of time and human resources and demands a significant initial investment, manual testing can be resource-intensive throughout the project’s lifespan. The reason for this is that expenses will be entirely dependent on the human resources used in testing, and the length of time required for testing may be larger than expected. However, while manual testing takes more time than automation testing and is more expensive in the long run, it is less expensive in terms of early expenses.
Testing limits
A number of technical constraints might wreak disaster on the manual testing approach. As a result, while manual testing involves human observation, which is useful in delivering user-friendliness and an improved user experience, it is not appropriate for a variety of vital testing kinds. This is especially true for non-functional categories, such as load, performance, and stress testing – jobs that are too difficult to conduct manually. On the other hand, there are some test cases that are too complex or impossible to automate.
Manual testing is ideal for
Exploratory testing
Exploring new product features from various angles is only possible with the manual testing approach. It enables inspecting a greater variety of pathways, discovering flaws that scripts would otherwise overlook.
Usability testing
A team must set up an effective testing plan with clear-cut usability goals, tasks, measurements, and the roles engaged in a usability test to ensure app usability and identify risk factors that limit it.
Random Testing
A manual tester is the only one who can undertake Random Testing. Its advantage is that it may be performed at any stage in the QA process and does not require any paperwork or planning.
Projects with a short timeline
It is not a good idea to begin automated tests when the project is only temporary. Manual testing will be enough to meet the project’s fundamental requirements. This may squander resources and render the automation ineffective.
Advantages of Automation Testing
For large-scale undertakings, it is cost-effective.
In the long run, automated testing is less expensive than manual testing. And, while it normally necessitates a larger initial expenditure, the ROI will be far more satisfying for all stakeholders in the long run.
improved software testing coverage
Because automated testing is handled by tools and scripts, it produces more accurate and trustworthy results, allows for much better resource allocation, and provides larger testing coverage.
Automation works best for
Regression testing
It is a good idea to automate regression testing to ensure that old app functionality continues to perform properly after being carried forward to new app versions.
Performance testing
Automation tools must be used to help app testing targeted at measuring the system’s behaviour and performance under demand. For example, the required simulation of any number of concurrent users must be automated because there are no acceptable manual alternatives.
Functional test cases that can be repeated
The ability to save manual testers from completing the same tests repeatedly is at the heart of automation’s cost-effectiveness. This contributes to the optimisation of the software quality assurance process and eliminates the monotony of repetitive testing.
What manual testing is incapable of achieving
The level of detail of current software systems is growing at an exponential rate. As a result, there are an increasing number of cases in which there is no manual testing technique that could help assure the quality of a certain feature of a system.
Faster results and simpler reporting
Because automated testing is performed by software tools, it is substantially faster than manual testing. The tools can also record test sessions and utilise them in different circumstances.
Summary
In conclusion, the debate between Manual Testing and Automation Testing is minor, with each approach offering distinct advantages. While manual testing ensures a meticulous, human touch in certain scenarios, automation excels in repetitive and large-scale testing requirements, enhancing efficiency.
