Why is Software testing important?
Automatic software tests give you a lot of freedom and, above all, you can be sure that the product is safe and meets the highest quality standards. Automated testing is based on the use of scripts and tool support. It is worth combining them with manual actions because some errors are impossible to detect by the system. Automatic testing will allow us to optimize the execution time of recurring tasks. The script allows you to find errors faster. Its precision determines how many defects it finds. Automation can apply to different types of tests. It includes functional, non-functional as well as structural testing.
Automated software tests - how does it work?
The main goal of companies offering software is to meet the expectations and needs of customers. To ensure this, it is necessary to constantly update the system. However, this may make it difficult to maintain the appropriate quality of the product. Process automation is a solution that can help maintain the highest standards. Automated testing is based on the execution of processes using scripts and tools prepared for a specific project.
The more precise solutions are introduced, the better the results will be and more errors will be found. It is worth noting that it is impossible to predict everything. Therefore, it happens that some errors that are easy to detect by the tester may be skipped by the script.
To avoid this, automatic software testing is often combined with manual testing. However, if we have created an application that requires constant updating, adding new elements, they are necessary to maintain efficiency and meet customer expectations. What can automated testing involve?
What does automated testing involve?
Automated software testing may include testing at various levels. It should be noted that the area of automation depends primarily on the needs and requirements of the software, customer expectations, and budget.
One of the cheapest, but also useful, is the automation of unit tests. The script then scans, for example, components, modules contained in the program. In the case of very complex systems, integration testing may be necessary, which includes many modules and functions. However, they require more money and time.
Automated tests often apply to all software components. Remember that it is associated with serious costs. The last type of test is acceptance tests, which are designed not to search for errors, but to check the completeness and compliance of the system with the specification, business requirements and, user expectations.
Types of automated software tests performed
Another division of activities is performed by testers according to what they are really concerned about. On this basis, functional and non-functional tests are distinguished. The first of them consists of verifying the specific functionality of the system. At the same time, it should be emphasized that functional testing can be implemented on all the above-mentioned software levels. It accompanies testers on activities ranging from unit testing to integration and acceptance. On the other hand, the second of the above-mentioned types of tests, i.e. non-functional ones, verify the operation of the entire system, not its specific functionalities. These include performance or security testing.
Testing automation also applies to structural tests, i.e. tests related to the source code of the system. The last type of testing involves re-validating the software after making changes. This is essential for the system to function properly and to meet the highest quality standards.
The benefits of automated software testing
Automated testing of software enables, above all, faster execution of tests than in the case of manual operations. Thanks to scripts and tools, we can minimize the risk of mistakes made by people. Detected errors and test results may be in the system and we can view them at any time. Automatic software testing is a good solution for performance, stress and, functional tests. It will also help to reduce the time it takes to execute tests on repetitive tasks. Depending on the design, the tests performed and their complexity, it may be associated with higher or lower costs.
