Summary
Key results
Regression testing time reduced from 3 weeks to 2 days
Test pass rate increased from 65% to over 90%
Pressure for speed and scale in travel software development
The client was developing a global sales platform for the travel industry, enabling fast search and booking of flights, hotels, and transportation services. The system was mission-critical, serving thousands of users worldwide.
As the platform grew, maintaining application quality became increasingly difficult – the traditional manual testing model could not keep up with the pace of product development. Manual regression scenarios took several months to complete, causing release delays and a risk of critical defects. The lack of QA automation made scaling operations difficult and reduced client confidence.
To shorten time-to-market and enable stable deployment of new product versions, the company entrusted the project to Sii Poland – a provider experienced in Testing & QA and software quality assurance at a global scale.
Scalable QA architecture based on regression test automation
To accelerate deployment cycles and improve product stability, Sii Poland’s experts designed and implemented a new QA model that fully automated regression testing. The cooperation lasted over four years and included multiple optimization phases, during which Sii’s team – at its peak consisting of ten specialists – developed and solidified the target automation model.
The scope of work included:
- Automation of test scenarios – more than 800 automation scripts replaced 1 300 manual regression tests, eliminating repetitive tasks and shortening testing cycles
- Analysis and optimization of test cases – a comprehensive review reduced redundancy, shortened execution time, and lowered maintenance costs
- Development of a test result analysis tool – the solution automatically evaluates QA outcomes and supports release-readiness decisions
- Creation of supporting components – additional web services improved environment stability and reduced process startup time
The new testing model made the QA process consistent, predictable, and easy to scale across an international environment. With each iteration, the team achieved shorter implementation times for system updates, giving the organization full control over both quality and product development pace.
Automation that drives growth and user experience
By introducing the new QA model, the client shortened the release cycle from three months to two weeks, while test success rates increased from 65% to over 90%.
Automation of QA processes significantly reduced manual workload and improved product stability, allowing engineering teams to focus on developing new features. The integrated testing environment now enables fast and secure deployment of new application versions across global operations.
With a more stable testing process, end users benefit from a more reliable booking system – free of delays, errors, and service interruptions. QA automation has become not only a tool for technical optimization but also a foundation for a superior user experience enjoyed by hundreds of thousands of platform users.
