Cross-browser testing is essential for ensuring a flawless user experience and delivering a digital confidence that turns customers into loyal users. It allows teams to identify and fix issues prior to release, reducing the risk of losing customers and revenue forever. Cross-browser testing can be challenging and expensive, but cloud-based platforms can help streamline the process, reduce costs, and increase efficiency. A balanced test strategy includes both manual and automated testing, with a mix of techniques such as performance, basic functionality, user interface, accessibility, and responsiveness tests. Teams should perform cross-browser testing at each stage of the software development lifecycle, using a strategic approach to selecting browsers and tools that meet their unique needs and requirements.
