In this competitive world, organizations face pressure to deliver high-quality products speedily. It is nearly impossible to meet these standards with manual testing alone, that is why automated testing is used.  Automation testing provides numerous benefits that assist firms in improving product quality in the market while saving money and resources. This blog describes the automation testing benefits and how it contributes to product excellence.

🎯Advantages of automation testing

➡️Increased Efficiency and Scalability:

Automation testing offers various services such as performance testing, load testing, regression testing, CI/CD integration which minimize the time of testing and boost the productivity of the application to fulfill user demand.

➡️Consistency:

The test scenarios which are automated as per the expected outcome run by automation testing on daily basis or after every change in the code provide the consistent result by eliminating human error and providing reliable result.

➡️Reusability:

 Once the test scenarios script is written down, it can be used to check the scenario until anything expected outcome changes for that scenario which saves the time of writing and executing script by reusing the same script for the different versions of the application.

➡️Faster Feedback/Early Bug Detection:

After code is pushed into the repository, the automation scripts group runs for the application to ensure that the new changes do not cause any defects for the existing functionalities. If there is any, developers can revert back or fix it immediately which shows the faster feedback and early bug detection in the development process than traditional testing can offer.

➡️Cost Saving:

Although initial setup of the automation testing is costly, it grants a large amount of cost saving in later on period. The defects found in postrelease, late feature release in market take away a larger amount of money with organization reputation than the automation initial setup cost.

➡️Improved Accuracy:

 The same flow executing every time showing no human error and improved the quality of the product.

➡️Better Coverage:

100% test coverage is difficult to achieve for any tester in a project particularly with manual testing. Manage test cases simultaneously, compared with previous release, tracking the bug and build cycle in manual process is complicated. Automation testing tools are presented as solutions for this problem with improving the product quality and assisting in testing such as UX testing, Database testing.

➡️Continuous Testing:

Automation testing supports continuous integration after every change in the repository and continuous delivery when all the scenarios passed into integration by facilitating continuous testing.

➡️Resource Optimization:

The resource count is reduced when repetitive tasks and CI/CD work done by automation and team members can focus on the more important tasks of the project.

➡️Parallel Testing:

Automation testing can run test scripts in multiple devices and multiple browsers at the same time which significantly reduces the time of the execution of test scenarios.

➡️Data Driven Testing:

In many functionalities, testers have to test the same workflow with the different data inputs which is time consuming specifically for the lengthy workflows. In automation scripts, users can pass the different data inputs into a single script using data driven testing by reducing time on writing the same test scenario multiple times.

➡️Automation Script Executing Anytime, Anywhere:

The CI/CD provides the facility to run the scripts anytime on the day/night without human presence and on any machine. 

➡️Reports:

The result of the executed automation scripts in the form report where graph, data table, reason of failing case everything is mentioned with video or screenshot save the time to analyze how many cases fail, what is the reason and also stakeholder, product manager can watch what’s the update of the application.

➡️Documentation:

 Automation test cases written in the form of expected workflow of the application with the logs, proper naming conversation and comments. That’s why many people say that automation serves as a live documentation of the requirements of an application.

Example of an ecommerce application

Implementing automation scripts for an e-commerce website/application with CI/CD integration delivers extensive benefits. Automated tests are written as live documentation of the project requirement and utilize data-driven testing for diverse inputs in a single test case with the additional feature of running tests simultaneously on various devices and browsers. After each new build, you can schedule test execution for smoke and regression cases to ensure consistent workflow results, reports for analysis, and rapid feedback for any bugs that arise. This advantage reduces costs and resources while improving the application’s or website’s efficiency and scalability.

Conclusion

In summary, test automation benefits which we discussed above helps the development process to effectively release products faster with high assurance. The QA team can focus on the other critical tasks that need human judgment, developer team is able to fix the defects early and also focus on the new features with assurance merging that it will not affect to already released cycle and last but not the least, project managers, stakeholders and clients can easily manage the project via setting priorities and doing root cause analysis for any delay or issue.
