Testing automation and manual testing: what are the differences?
Today, more than ever, companies must be able to deliver optimal digital experiences from start to finish. In order to do so, all the digital products that we use in our day-to-day lives go through quality assurance processes before being launched. These processes can be carried out through manual testing or automated testing.
Although we live in a paradigm that seeks to maximize process automation, it is important to understand the advantages of each method as well as the differences between them. When is it advisable to automate? And when is manual testing the best ally for effective development?
Testing is a method that allows us to verify that the software code used in a project works the way it should. Test analysts implement processes that allow them to find defects (or bugs) in software, and report them so that development teams can correct them. For example, if we talk about the new app for a medical center, testing will consist of checking, among many other things, that users can reserve, cancel and change appointments without glitches.
If we had to define it in a few words, in any of its formats, testing allows us to ensure the quality of the digital experiences that a company offers, saving implementation time and money, and prioritizing end-user satisfaction. For this reason, QA & software testing services have become increasingly relevant for the healthcare, banking, fintech and e-commerce industries.
WHAT IS TESTING AUTOMATION?
Testing Automation – also known as automated testing- is a current approach and one that is on everyone’s mind, since it allows automatic and repetitive testing. “Automation is implemented in fixed and stable sections, which will not be modified in the short term and which also require a repeatable precision at the speed of a machine”, explains Fernando Barrionuevo, leader of the Automation Chapter at Arbusta.
Thanks to this possibility, companies can detect errors in their projects promptly – and save time and money correcting them. Likewise, by eliminating routine tasks, this method frees up time to carry out more in-depth activities related to the development and implementation of software. Automated testing is the recommended method when the solution is stable, the customer experience is given high priority and time-to-market is critical, or in cases where repeatable precision is vital, that is, the ability that machines have, and people struggle with, to repeat a process as many times as necessary without getting distracted.
THE ADVANTAGES OF MANUAL TESTING
It is often believed that automated testing will end up making manual testing disappear. But nothing could be further from the truth. “Automation is not a replacement for manual testing, but instead, a complementary process,” adds Barrionuevo.
Manual tests are carried out by a person who, based on test cases, behaves as a user would to detect and report faults. Manual tests are used mainly for functional, usability and / or exploratory tests.
Manual testing allows in-depth tests on new features to verify they work correctly, and it can also be the trigger for feedback to improve different aspects, such as usability and user experience. From this complementary perspective, the testing automation method is recommended when regression testing (exhaustive tests that are repeated periodically throughout the versions) is required to ensure that new implementations have not created bugs in other, stable sections, when the business model is already known.
ARBUSTA’S TESTING SERVICES
Ensure the quality of its clients’ digital assets, Arbusta implements hybrid strategies that combine automation with manual testing. Depending on the specific needs of each project, testing teams use both approaches in achieve greater effectiveness and a more efficient use of resources.
For example, in 2020 we began to work with the Rosario Stock Exchange on a testing automation project for one of its main business applications.
“We chose Arbusta as a supplier for an initial work cycle, in which we defined the importance of automating 3 flows. Whether in the quality of the deliverables or in the management of the project, Arbusta always demonstrated a true understanding of the issues, and exhibited a very talented human resource team. Arbusta accompanied us in this process with knowledge transfer and with support on specific consultations. The company also assisted us with setting up development environments within our platforms. The experience was very good, ”said Ruben López, Head of Operations at the Rosario Stock Exchange.
