To overcome the aforementioned challenges, RUBICON and the fintech company's teams came up with some solutions. Here are the solutions we implemented:

• Data consistency - The client made sure that the data in the testing environment was always constant, even with the exception of time-based data, which shifted daily. RUBICON engineered a custom-designed architecture product that was modeled specifically for the client's project. The data was loaded into the tests and then matched with the data collected from the application.

• Running tests in parallel - Serenity-Grid and Jenkins were used to distribute test runs, allowing the software team to run tests in parallel. This reduced the amount of time a developer had to wait for a test run to be completed.

• Optimizing code - The software development team prioritized optimizing the tasks and questions since they were the building blocks of tests. Serenity's report feature allowed the team to check the execution time for every task and action so they could identify the slow-performing ones and focus on them.

RUBICON's dedicated team composed of one tech lead and two quality assurance automation engineers worked on writing, running, and maintaining tests for the client's software. The framework the team used to write the end-to-end automation tests was Serenity.

Serenity produces an end report that presents the behavior of the web app, such as the user's series of steps on the web app, screenshot for each step, the outcome, and duration. Serenity uses abstraction to make the tests more humanly readable so that each person on the client's team can easily read and understand the tests.

Since the software was constantly changing during the project with new features, tweaks, and updates, RUBICON's team decided to use the Kanban methodology due to its flexibility. Using Kanban, RUBICON's team ran daily standups where the team members synced their current status with each other and exchanged ideas. In addition, weekly meetings and retrospectives were held where tickets were refined, and both the process and performance were evaluated.

By implementing these solutions and following an agile methodology, RUBICON's team was able to write and maintain efficient end-to-end automation tests for the client's software, ensuring a high level of quality and consistency in the final product.
