Our client is a leading financial institution in Southeast Europe providing retail, corporate, and investment banking services.
Operating in a very regulated and security demanding environment, they were looking at improving their quality assurance processes for online and mobile banking platforms.
Our client had a dedicated manual QA team but didn’t have the internal expertise to design, develop, and maintain a reliable test automation framework.
Since most of their customers now use digital channels, the client wanted to release updates faster, improve testing, and be more confident in their product quality - all while staying secure and compliant.
Lack of experience with automation frameworks or scripting. The client needed an automation solution they could use, maintain, and improve themselves.
Strict security rules for handling sensitive personal and financial data. Any new solution has to meet these standards and requirements.
QA team could easily use the new automation framework. It needed to be easy to understand, well-documented, and come with good training.
We managed to automate the full smoke testing suite which guarantees the quick validation after each build. Аlso we have covered the most important user flows of the business.
Check how things worked on different browses and devices in minutes instead of hours.
Tests run automatically after each build, dashboards show reports right away, product and engineering teams can see how quality is trending.
Learned Java for automation, wrote automated tests on their current systems, changed and made the framework better, practiced fixing bugs and keeping things running.
To run tests at the same time on many devices, we used BrowserStack for wide coverage across different browsers and devices.
For the online platform, we automated things with Selenium WebDriver for steady and dependable web UI tests.
For mobile testing, we added the Appium library to our setup. This let us automate both iOS and Android apps within the same system.
To make test data faster and help with system tasks, we added API-based processes. This really sped up test prep and made things more reliable.
All automated tests were added to the bank’s Jenkins CI/CD pipeline. This means tests run automatically after each build, so we always know the product quality.
During the three-month training, the QA team built automated tests on their own and tweaked tests we had already made. This hands-on training gave them real experience and confidence with the new system.
The client now uses one system for automated testing on different browsers, platforms, and devices, which fits today's QA needs.
The team learned how to manage, grow, and improve the system. This gives them control and lowers the need for outside help.
Key processes now run automatically after each build, making release validation faster and more reliable.
3 times faster release cycle - automation and CI/CD cut down testing time, so the bank can release updates quicker.
Since automation handles the repeated tasks, the QA team can focus on unusual cases, exploratory testing, and ways to improve quality.
Long term ROI as the team owns a system that can grow and be maintained, keeping external costs down at the same time.
