Digital transformation (DT) has completely reshaped the way businesses operate today. Just have a look at some breathtaking, motivational success stories. Sonnen Group
So, it’s not surprising that 64% of McKinsey’s
However, DT journeys are challenging due to the intricacy of modern technologies and may even take years, especially if the business is large. How can companies ease and speed up this initiative? Among other things, they can rely on automated testing as it accelerates time to benefits and raises confidence in the quality of applied software solutions.
Therefore, in this article, I’ll focus on the test automation role within DT, benefits, and tips for successful adoption.
DT can be defined as a set of strategic actions aimed at rearranging a company’s key processes and upgrading the leveraged tech stack (the introduction of AI/ML, IoT, cloud, big data, robotics, digital twins, blockchain, etc.) to take business to the next level. This significant modification can contribute to multiple benefits, including but not limited to:
The introduction of cutting-edge DT technologies, such as AI/ML, AR/VR, robotics, big data, RPA, or cloud, is fraught with challenges due to their high intricacy, newness, and probable lack of data about the tiniest nuances of their operation. How can companies make sure that solutions based on these technologies work correctly and without disruptions? How to confirm that end users won’t face any problems, especially those affecting data security?
I’d say introduce software testing. When done from the earliest development stages of the project driven by Agile methodologies, quality assurance helps detect defects of diverse severity and fix them in a cost-effective manner before they turn into a real problem after software launch, contributing to end-user churn.
However, often, software development projects deal with large functionality upgrades or the introduction of new features, which entails a considerable amount of work. In this case, relying on manual testing alone isn’t a good idea, that’s why project teams make use of test automation, which can bring in the following perks:
To improve software testing capabilities, consistently meet goals on time, and support a DT project, companies can follow a few useful tips that will simplify the introduction of automated testing:
Preparation is essential to success within any sphere. To direct efforts intelligently, first, it’s necessary to have a clear vision of what verifications should be automated. I’d suggest that teams initially focus on functionality that plays a key role for the organization (e.g., payment or delivery modules, product catalogs, making orders). Also, remember that the candidates for automation are the tests that are run often, are stable (for instance, logging into an application or accessing a database will rarely be modified over time), and deal with large data amounts. In addition, I think it’s a good idea to automate manual tests that require a lot of input from QA engineers and thus mitigate human error.
Choosing the tool that will make your automation possible is the next step. The choice should depend on a variety of important factors. Among them, first, I’d define a budget as it determines whether you have a commercial, no-cost, or customized test automation framework.
I’d also suggest considering your QA team’s ability to master the chosen solution, otherwise, there’s a need to establish a tailored training course for them. Therefore, to avoid mistakes when choosing the right tool, it’s necessary to research available options and compare them to make a well-thought-out decision.
Before writing and executing tests, it’s important that QA automation engineers get the right amount of relevant test data that is used in the QA process. It can be created in several ways. QA specialists can either build synthetic data or copy the information from the production environment. To ensure the information fully suits your testing purposes, it’s vital to check that the data in general is similar to real-world conditions and also comprises exceptional cases (e.g., using a gift card).
A detailed description of further testing activities is a crucial step that cannot be omitted. Why? A comprehensive test plan ensures that all project specialists are always informed about the current situation and progress, making sure everything proceeds as planned. In addition, it provides project newcomers with an opportunity to quickly delve into the project’s testing process and bring value to the QA team earlier.
What to include in the plan? I’d focus on the overview of testing goals, strategy, scope, resources, deadlines, environment, deliverables, liabilities, and probable concerns. The more relevant data is outlined, the better for all involved.
After the preparation process is over, it’s time to write automated tests and run them to verify software quality, detect issues, and accelerate the overall QA process. I’d suggest creating small tests that verify only one aspect at a time to avoid unexpected failures and ensure easier maintenance. Make sure you run tests simultaneously to get the desired results faster. In addition, do not forget to establish the practice of generating detailed software testing reports that display the major findings — objectives, scope, IT product’s quality status, statistics on passes/failed tests, description of detected defects (severity, density, etc.), and more.
As the IT product evolves over time, the addition of new functionality is inevitable. This means that some automated scripts may become irrelevant. Therefore, timely updates are important to make sure that test coverage grows in parallel with the features. Also, it’s important to monitor test automation progress in real time, which is possible to do with relevant metrics.
I’d recommend considering those describing coverage, the volume of passed/failed tests and identified issues, the number of defects in the production environment, the stability of tests, and some others.
Test automation is a true assistant for ensuring high software quality and accelerating testing velocity within a DT project. To ensure its successful implementation and high efficiency, QA teams can think of the scope, testing tools, data, plan, scripts, maintenance, and KPIs. In addition, they should remember that test automation shouldn’t completely replace manual testing but become a valuable supplement, contributing to reaching better testing outcomes.
