Ensures test accuracy:

Manual testing involves human intervention and this may have chances for some un-notified errors in the testing process. Manual test cycles might lead to errors, but with automated software testing tools, there is an assurance that the testing practice and validation of the application are performed with good accuracy as errors are identified at every phase.

Eases regression testing time:

Performing regression testing with manual methods takes a lot of time and human efforts which may also lead to a lot of unidentified bugs. The repetition of the same test cases over time and again might cause disinterest amongst the testers and may even reduce the overall testing efficiency. However, these can be resolved when automated regression testing is practised with QA automation testing tools and manual testers get time to be used for other quality works.

Facilitates with re-usable test scripts:

With automated software testing in use, it eases the tester’s efforts as the test scripts can be reused with some minor changes made in the test scripts. Also, these scripts can be used multiple times as they can be stored, and can be re-used for repeating the tests.

Helps to Validate Complex Scenarios effectively:

Automated testing as a service is effective to validate numerous complex scenarios as most of today’s applications are complex apps with smart and IoT connected devices. Automated testing with various types of test automation tools eases the testing process as the tools can be used to test irrespective of the time.

Automated Testing Cost-Wise Benefits

Saves Cost:

With automated app testing, enterprises can effectively save their budget as the test cases are run at a faster speed, defects are identified early and fixed before it is moved to production. Though the initial costs of automation are high, but when once the automated test framework is developed, it eases the testing tasks and remarkably saves the overall costs.

Increases ROI:

Every enterprise aims for achieving better returns from its investments. With the development of an effective test automation framework, returns are huge as testing is performed faster with the inbuilt features. Moreover, automation testing QA delivers faster and quality results, improves the time to market and finally ensures increased return on investment.

Saves Time:

As tests are run automatically 24×7, automated software testing helps to save time. Moreover, with automated testing tools, manual scripts are automated and the regression testing time will be drastically reduced. This eventually leads to saving the delivery time of the application and largely saves a lot of manual efforts and saves time.

How does Automated Testing work?

Any organization that wants to implement automation testing follows a testing framework approach. The most favoured testing frameworks are keyword-driven framework, data-driven framework, linear scripting framework and modular testing framework.

To test small applications, a linear scripting framework is used, because it uses test scripts that don’t require much planning and also do not support reusable scripts.

When it comes to a modular testing framework, a software tester develops test scripts to perform small, independent tests in order to reduce redundancy.

Data-driven frameworks enable software testers to develop test scripts that are able to work for multiple data sets. This framework offers wide quality coverage with fewer tests.

Keyword-driven frameworks are worked out using table formats to define keywords for each function and execution method. Those software testers who don’t have in-depth knowledge of programming can use keywords to develop test scripts.

The most popular test automation tools which are open-source are Selenium 4, Robotium and Cypress. Selenium can automate and run tests across various web browsers and also works well with popular programming languages such as C#, Java and Python. Robotium is best used for user acceptance, function and system tests for android devices. End-to-end testing, integration and unit tests work perfectly well with the Cypress tool.
