Case Study: Leading Wireless Service Provider achieves 80% reduction in regression testing time with Hexaware

Mobile App Automation Testing for a Leading Wireless Service Provider

Leading Wireless Service Provider, a US nationwide wireless leader with 40 million customers and over $71 billion in annual revenue, faced a growing mobile portfolio of 32 consumer and enterprise apps with more than 1,000 manual test cases across multiple (including prototype) devices. The constant feature growth and frequent new builds made manual testing slow and hard to maintain; the customer engaged Hexaware for Digital Assurance and Mobile App Automation Testing to reduce testing time, scale coverage, and improve quality without extending release cycles.

Hexaware evaluated tools and implemented a hybrid mobile automation framework (SeeTest and Eclipse Integrated Mobile Testing Solution), built reusable regression suites, developed batch execution/MATS tooling, and automated scripts for prototype devices. Hexaware delivered testing for 32 apps and 1,000 test cases across five devices, automated 65% of regression suites, cut regression cycle time by 80%, reduced script development effort by 30%, and achieved 99.5% defect detection efficiency—resulting in faster releases, higher quality, and improved brand visibility.
