With continuous technological innovations, applications have become more complex and advanced. Customers now expect enterprises to continuously innovate and roll out application updates to meet their evolving demands. As the features in the application keep growing, the need for quality also increases relatively.
To accelerate software development, enterprises have included Agile and DevOps methodologies that have made the swift delivery of quality assurance and software testing even more challenging. In several applications, the addition of even a small feature makes it necessary to test all other features to make sure that the behavior and user experience of the application is foolproof. Manual testing efforts can not handle such an enormous amount of test cases on a regular basis. This is where test automation kicks in, making Agile and DevOps a reality.
Let us find out how test automation is increasing the efficiency and productivity of organizations.
#1 Saves Resources
Automation testing is less resource-intensive in the long run that helps in saving a lot of time and money. It is a common requirement to repeat software tests as soon as the source code is modified. For each and every release, the software is tested on all hardware configurations and software operating systems. The manual repetition of these tests would cost a lot of money and precious time. While an effective test strategy will optimize test coverage, test automation will bring in the required scalability and repeatability in test efforts.
Test automation can be deployed over and over again without any additional cost at a faster pace. Hence, reducing the time for repetitive testing from days to hours leading to cut down in project costs.
#2 Increased Test Coverage
Automated software testing helps in enhancing the scope and depth of tests. Test engineers can run lengthy tests without worrying about errors and the quality of results. However, in some cases, it makes sense to start with manual testing; especially in the early stage of the software development lifecycle (SDLC).
This approach helps test engineers to fine-tune the test strategy, set test requirements and plan the execution of the test. After some time, when the testing process gets fine-tuned and standardized, automated tests can be implemented.
Automated testing also assists test engineers to avoid human errors that could erupt from doing repetitive and redundant tasks. Automated tests ensure precise delivery while taking all the required information into consideration.
#3 Development and Testing Go Simultaneously
Software tests are repeated several times during the development cycle to achieve the best possible quality assurance. Whenever there is any modification in the source code, the software test is repeated.
Each release of the software should be tested thoroughly on all the supported variants of operating systems and several hardware configurations. Executing these tests repeatedly through manual testers would cost a fortune and a lot of time. Test automation has enabled QA to match the speed of Agile or DevOps projects while staying cost-efficient.
However, it is also crucial to identify the number of test cases that need to be tested to analyze the feasibility of test automation. For fewer test cases, automation testing may turn out to be more expensive than expected.
In several projects, it makes sense to kickstart with manual testing in the early phase of the software development lifecycle. This allows test engineers to fine-tune their strategy, set reasonable test requirements and plan the test execution during development. After the standardization of the testing process, automated tests are deployed to achieve the desired results.
#4 Test Automation Frameworks, Test Cases and Tools
To maximize test coverage and achieve the best results in the desired time, it is crucial to select a robust testing method that could be cross-platform as well. Automated testing methodology is leveraged for both reducing the costs of the project and validating requirements by generating automated test cases.
However, complete automation of big software entities incurs big costs that several organizations are not ready to pay. Test engineers should always keep in mind that frameworks including UI Automator, Robotium, Selenium, and Appium among others are just methods. Every framework comes with its unique set of utilities; some are more suitable for the web and hybrid application testing or some for native application testing. However, to get the most out of each methodology and framework, you need to have access to high-quality testing tools.
#5 Test Coverage, Reusability and Open Standards
Automated testing helps in enhancing software quality significantly by increasing the scope and depth of test cases. It enables test engineers to efficiently run lengthy and thorough tests that are normally not executed through manual testing. Automated tests ensure that test cases get complete access to the application and all the aspects are tested including data tables, memory content, internal program, and file content to identify the sanctity of software products.
Automated tests efficiently execute thousands of complex test cases during every test run. Manual resources freed from testing contribute more towards creating automated test cases. Test engineers can also easily extend the test coverage by increasing different variety of test cases.
However, to achieve optimum efficiency, it is crucial to choose the combination of the right device set. The selection of device also depends largely on the market that the business is trying to reach through its software. For instance, apart from picking up the most popular Android devices, it is also crucial to consider display resolution platform/OS version, hardware configuration and memory of the device among others.
If test engineers want to reuse test cases later then it is advisable to rely on open and transparent APIs for testing.
#6 Efficiency and Quality-at-Speed
Enterprises are facing the challenge of producing high-quality and reliable software in a highly competitive environment. Automated software testing ensures a cost-efficient solution while reducing time-to-market. Here is how it helps:
- Enhances test efficiency
- Increase test effectiveness and reduces time-to-market
Testing efficiency is calculated by taking the average number of tests that can run for an hour on testers’ time. Higher testing efficiency leads to lesser development time and costs, resulting in better bottom lines.
Test effectiveness is calculated by the rate at which a testing tool or technology is able to identify bugs. Increased effectiveness enables the organization to cut costs by releasing flawless products that ensure customer satisfaction and loyalty.
Efficient test automation is enabling enterprises to achieve better results while reducing time-to-market. Automated testing has reduced weeks or months of time that a manual testing effort would have taken. Apart from enhancing the efficiency of SDLC, automation testing is also helping in freeing up a lot of resources that can be utilized for a more focussed approach towards business development.
