The holiday shopping season is approaching, bringing significant online sales and traffic spikes. With almost 50% of holiday shopping done online, mobile devices play a huge part in the mix. To ensure readiness, cross-browser and load testing are crucial to identify bugs, errors, and bottlenecks before Black Friday and Cyber Monday. Cross-browser testing is essential to expand coverage to as many browser/OS combinations as possible, while load testing simulates user behavior and traffic from multiple geo-locations to analyze performance and discover bottlenecks. By conducting these tests quickly and easily, retailers can avoid losing money and frustrated customers due to incompatibility issues or website crashes, and instead be prepared to handle the heavy holiday loads and traffic spikes.
