What You Need to Know About Test Automation

It isn't easy, but it's worth it. Implementing test automation within your organization might be the best decision you'll ever make.

Test automation implementation is tricky — but if it's done right, it can be highly rewarding for the organization. It makes sense for businesses to automate the functionality that is most used and most critical. Equally important automation factors to consider are the areas of specified service levels of agreement, followed by repetitive procedures and tasks prone to error.

Test Automation Tips

Test automation is only effective if it's done correctly. These tips will help you ensure that you get the job done right. 

The Broadly Used Test Automation Tools

Automated testing refers to either scripting or recording a test such that there is no necessity for manual intervention. BDD and automation wrappers are widely used test automation tools. BDD or readable acceptance testing fixtures let you write the scripts, while automation wrappers would enable easier automation.

A Deterministic System Output Is Productive

System tests are automated tests of larger, high-level functionality. System tests feed clean input (such as databases, user input, etc.) for end-to-end testing, validating the output against pre-defined results. It is vital that the system output is deterministic, and depends mainly on the input. Each time there are changes in the system, the system test cases also change.

It Is Akin to Software Development

A test automation effort is equivalent to the standard software development project. Right from defining what ought to be automated to designing the test automation and coding in the intricate details, the entire process requires attention-to-detail and constant maintenance of code.

SDETs Play an Important Role

The right set of skills is crucial for effective test automation. There is a requirement for software development engineers in test (SDET) that can lead test automation processes with their best efforts. Good testers are still necessary to identify and write test cases for what needs to be tested. A test automator, on the other hand, takes these test cases and writes code to automate the process of executing those tests.

The Initial Costs Are High

Test automation is an investment, and there is a high requirement for time and resources in the initial stages, in order for the organization to be able to reap benefits at later stages. This essentially implies that there usually is not a positive pay-off while automating the current release of the application. Rather, it is more beneficial to run automated tests every subsequent release. Therefore, it becomes very important to ensure that the scripts can be easily maintained.

When It Is Best to Automate

It is best to automate the testing process when there is a lot of regression work. When there is a necessity to ensure that new bug fixes and releases have not introduced new bugs, it is important to test the previous/existing functionality as well. In such a scenario, manual testing is not effective, in terms of company cost, resources, time, etc. it is hence best to opt for automation, under such circumstances.

It is recommended to manually test individual pieces of code to verify that it is working as per code requirements. Acceptance test cases and automated scenarios can be incorporated as per the unit testing process.

It is a good practice to automate testing when the GUI is nearly frozen in place, but there remain frequent functional changes. Testing the application where the code is changing frequently is best done via automation of the test code.

Advantages of Open-Source Test Automation Framework

You wouldn't make the effort to automate if it weren't beneficial. Check out the following benefits of open-source test automation.

Economic

An open-source test automation framework is more reasonably priced in comparison to standard testing tools. The licensing costs are significantly lower and demand minimal hardware requirements. In addition, the testing components are easy to re-use and their high degree of scalability ensures that they can easily manage performance and load testing. Organizations can also leverage the flexible pricing plans that enable testers to adjust their total cloud storage according to their specific testing needs.

Tailor-Made

Owing to the open-sourced nature of the software, it can be altered relatively smoothly, to suit a testing department’s specific requirements. This conveniently editable code allows for smoother functionality, which, in the case of closed proprietary software packages, becomes more problematic, and occasionally possibly even damaging.

More Collaborative

Online communities thrive in open-source automation frameworks, as it enables testers to overcome obstacles by consulting the vast fields of information available on the web. Teams that operate from different locations can also work together through the centralized server, without the need to make several downloads and uploads in the constant flow of information transfer.

Swifter Testing

Test cycles with open-source tools tend to be shorter, rather than with traditional tools. Setup and tool deployment are also pretty swift, and there is no need for a mind-numbing installation process. Updates happen in real-time without affecting productivity, and the overall time-to-market is reduced. This gives organizations a significant push ahead in the boundless app delivery race.

Virtualization

Virtualization empowers organizations to utilize their resources in the best manner and ensures that testing is ultimately more effective and comprehensible. Virtualization also allows the easy sharing of resources with an associated dip in costs, thereby hugely benefiting the organization.
