Understanding Challenges

The bank embarked on a digital transformation to modernize its branches and meet evolving market demands. Faced with the complexities of a large-scale digital transformation, they needed a solution to maintain high-quality standards while integrating advanced features such as branch digitalization, biometric authorization, and robotic process automation.

Their approach required a powerful development platform combined with effective automated testing to meet strict deadlines without compromising quality.

At the outset, an alternative approach was proposed: building a completely new system with an offshore company. This would have required a team of over 100 professionals and more than a year of work—an impractical solution given the project's scope and tight deadlines.

Instead, the organization chose GeneXus for its ability to accelerate software development while managing the complexity of large-scale systems. GeneXus stood out among competitors for using Artificial Intelligence to automate tasks and enable developers to create complex systems efficiently.

Solutions and Activities

To address these challenges, the bank adopted GeneXus alongside GXtest, a cutting-edge testing automation solution developed by Abstracta for GeneXus. GXtest played a crucial role in streamlining testing and advancing the bank’s digital transformation by automating processes and simplifying complexities.

This enabled the team to continuously execute regression testing, significantly reducing the risk of introducing errors during updates and iterations. Despite the waterfall-like approach characteristic of core banking system development, GXtest’s adaptability supported faster cycles and incremental improvements.

GXtest provided powerful tools such as the GXtest Designer, which offered an intuitive interface for modeling test cases, and the GXtest Recorder, which captured user interactions seamlessly to generate automated test cases.

These capabilities empowered teams with diverse technical backgrounds to execute functional tests efficiently across complex systems, enabling high-quality results with minimal manual effort.
