As cloud adoption becomes ubiquitous, QA testing is evolving towards cloud-based solutions, offering benefits such as reduced costs, scalability, and advanced testing capabilities. Traditional on-premises testing environments, while private and controlled, face challenges in scaling and maintaining infrastructure. Cloud testing leverages automation, enabling QA teams to dynamically provision test environments, deploy applications, and conduct functional and non-functional tests using CI/CD frameworks. Chaos Engineering emerges as a key tool for testing application resilience by introducing controlled failure scenarios to identify potential weaknesses. As QA teams adapt to these new methods, building engineering skills in declarative programming and infrastructure management becomes essential. While transitioning to cloud testing can be complex, the integration of test automation and resilience testing techniques promises significant efficiency gains and improved application reliability.
