Next, I perform exploratory testing to identify any obvious issues, followed by creating and executing test cases for functional, usability, and performance testing. I also ensure cross-browser and device compatibility, and finally, I document any defects and retest after fixes are applied.
Ques:- Can you explain the architecture of AEM and its core components (Sling, OSGi, JCR)
Right Answer:
AEM (Adobe Experience Manager) architecture is based on three core components:

1. **Sling**: A web framework that maps HTTP requests to content resources. It allows developers to create dynamic web applications by using a resource-oriented approach, enabling easy access to content stored in the JCR.

2. **OSGi**: A modular system and service platform that allows for the dynamic loading and unloading of components (bundles). In AEM, OSGi manages the lifecycle of these components, enabling modular development and deployment.

3. **JCR (Java Content Repository)**: A specification for a content repository that stores and manages content in a hierarchical structure. AEM uses JCR to store all content, including pages, assets, and configurations, allowing for efficient content retrieval and management.

Together, these components enable AEM to deliver a flexible, scalable, and efficient content management solution.
