Salesforce is a leading cloud-based CRM system utilized by over 150,000 businesses to manage customer relationships, enhance business processes, and achieve customer satisfaction and revenue goals. The platform offers two main interfaces: the older Salesforce Classic and the newer Lightning platform, both of which allow for extensive customization to meet specific business needs. Testing is crucial in Salesforce to ensure that customizations do not disrupt existing functionalities, with a focus on both manual and automated testing approaches. Key testing challenges include varying browser and operating system compatibility, particularly between the Classic and Lightning platforms, and the need for robust testing environments, which can be facilitated through cloud-based solutions like LambdaTest. The testing process involves ensuring UI consistency, business logic integrity, and integration with other systems while leveraging tools like Selenium and Lightning Testing Service for automation. As Salesforce evolves, maintaining rigorous testing practices remains essential to prevent business disruptions and ensure the seamless release of custom features.
