An integral part of software product development is testing, which can be manual or automated. The quality of software can be improved through test automation and thus the user experience can be enhanced. In this article you will learn about automated testing and we will discuss the best tools for automated testing.

Software testing automation is handled by an IT tester (read more about what does a software tester do) who performs software testing using scripting sequences to ensure software security and functionality according to predetermined requirements. Based on the found information, IT tester then compares the data with the results of previous tests. The goal of automated testing is to find all possible bugs, flaws, problems and potential risks that could have a negative impact on the final product.

In addition to the automation tester, the QA tester for automated software testing is also involved in QA (Quality Assurance ). He is in charge of designing the test scripts, while he already works with test engineers and developers on testing using testing frameworks such as JUnit for Java and Pytest for Python.

There are five types of automated testing

Each test environment as well as test case are unique. Therefore, the automated testing tool needs to be adapted to them as well, depending on the product or application being tested:

  • Code analysis – consists of various testing tools and is used to obtain an analysis of a specific area in the context of the source code. With it we can, for example, find potential security vulnerabilities, check usability, and so on.
  • Unit tests – they focus on testing each software component during the development phase and provide immediate feedback on the written code.
  • Integration tests/end-to-end tests – used to test larger parts of the software as a whole to ensure that the individual components work together according to the specified requirements.
  • Acceptance testing – is a verifying of correct functioning of the product based on user requirements. Its purpose is to assess whether the software is ready for release and later use.
  • Smoke testing – used to check the stability of software after a new software release.

How does automated testing work?

As part of the software testing automation process, the tester performs several steps. Before testing begins, the tester chooses the test tool to be used, taking into account its suitability for the specific testing area. He then determines the scope of automation based on the main testing objectives, the complexity of the test, technical feasibility and the number of resources.

Automated testing has different phases of the process

The third step is the planning phase, which consists of preparing a test strategy with defining the goals, framework features and how to use the test tool. In addition, a plan for scripting and executing test cases for the development team needs to be created. The implementation phase already includes the actual testing of the product, followed by ongoing maintenance to keep the test scripts and tools up-to-date.

Benefits of test automation in software development

Unlike manual testing, it does not need to be performed manually, so it comes with several benefits. Automated testing can be carried out at any time and is extremely efficient. It reduces overall testing time and the software development lifecycle itself, reduces errors caused by inattention or inaccuracy and also helps automate monotonous tasks. This allows testers to perform multiple tests at once, more frequently, without more effort and with more accurate results. Other benefits of automation are listed below:

1. Faster feedback cycle
With test automation, organizations can reduce the time it takes to complete the feedback cycle for new software features. If testers can provide software input to the development team faster, then the development team can fix bugs in the code faster. By increasing the speed of the feedback cycle, companies can eliminate the risk of releasing defective software.

2. Parallel testing on multiple platforms
Cross-browser compatibility is an important feature to check during the software development process. As there are many browsers available on the market, manually testing the software on all browsers is a lengthy process. Using test automation tools, testers can create a wider variety of test cases to perform cross-browser testing. Therefore, the testing team can quickly and simultaneously complete the testing of the software application across different browsers, operating systems and devices.

3. Reusability of test scripts
Since test case development requires a lot of time and effort, reusability of test scripts is a major advantage of automated testing. To test new operating systems or devices, testers must always create different test scripts for each test across browsers. The reusability of automated test scripts allows testers to better optimize their testing time.

4. Maximum test coverage
Achieving 100% test coverage for complex applications is very challenging for testers. This is even harder for manual testing because it is difficult to handle many test cases at the same time. A suitable solution to this problem may be to automate the testing processes. Test automation tools can help testers by providing additional test coverage and assisting them in testing features such as user interfaces, databases, and servers. These tools will allow testers to improve the quality of applications without affecting their functionality.

5. 24×7 test execution
Compared to manual testing, a significant advantage of test automation is the flexibility to perform testing at any time of the day. Since manual testing requires human effort, it is not possible to perform 24X7 testing. Automated testing allows testers to schedule automated remote test execution at any time of the day. Using automated testing tools, test teams can generate detailed reports with overview on tests performed to analyze applications at any time of the day at their convenience.

6. Scalability
When organizations have to manually execute a large number of test cases, they need to expand their workforce accordingly. However, in the case of automated testing, the process is highly scalable. An efficient and scalable test automation strategy leverages AI/ML to dynamically select scope, detect bugs, improve test coverage, and offer better control and transparency over the testing process while reducing testing cycles, security concerns and risks.

7. Low business costs and better use of human resources
Although automating testing processes can be a big investment for businesses, it can reduce their overall operating costs through efficient use of resources. Thanks to test automation tools, businesses need very little human resources to carry out the testing process. As enterprises lack the manpower to perform high-level tasks such as planning and product management, enterprises can use their workforce to perform such tasks. These factors will help organisations achieve greater efficiency and profitability.

8. Better regression testing
Performing manual regression testing of applications is a tedious process. In this type of testing, testers must repeatedly test a set of similar test cases to ensure that the bug is removed. This has been a critical pain point for developers and testers for so long. Repeated testing can cause delays in software releases and reduce the effectiveness of testers. Automated regression testing is the perfect solution to this problem.
