  What is CI, CD & CT? These are key concepts in modern software development practices  (DevOps) that focus on automating and improving the process of building, testing, and deploying software. CI (Continuous Integration): Continuous Integration is a development practice where code changes are frequently integrated into a shared repository(e.g.: GitHub ). The primary goal is to catch integration issues early by automatically building and testing code as soon as it's integrated. CI helps prevent the accumulation of bugs, ensures code consistency, and promotes collaboration among developers. CD (Continuous Delivery): Continuous Delivery extends CI by automating the deployment process to various environments, making the codebase always deployable. The goal is to have automated deployment pipelines that enable efficient and consistent releases. CD emphasizes keeping the application in a deployable state, enabling frequent, reliable, and low-risk deployments. CT (Continuous Tes...

  What is a compatibility test and how are they performed? Compatibility testing is a type of software testing that evaluates how well a software application performs across different environments, configurations, devices, browsers, operating systems, and network conditions. Performing compatibility testing involves the following steps: 1. Identify Target Environments: Determine the range of platforms, devices, browsers, operating systems, and network conditions that the application should be compatible with. 2. Create a Test Matrix: Create a matrix that maps the combinations of environments, configurations, and devices to be tested. 3. Testing Tools and Infrastructure: Use testing tools and frameworks that can simulate various environments and configurations. Tools like virtual machines, emulators, and cloud-based testing services can be used to set up and test different combinations. 4. Functional Testing: Verify that the application's core functionalities work as expected across...
