Difference between System, Integration, and E2E testing

Different levels of testing focus on various aspects of a software application.

  • 1. System Testing:




  1. Focuses on testing the complete software application to ensure it meets specified requirements and functions as expected.
  2. It aims to ensure that all components of the software work together as expected and meet the specified requirements.
  3. System testing checks the software's functionality, performance, security, and other non-functional aspects.


  • 2. Integration Testing:




  1. Focuses on testing interactions between different components or modules to verify their correct integration.
  2. The goal is to identify and resolve any issues that may arise when these individual parts are combined and interact with each other.
  3. Integration testing can uncover problems like interface mismatches, data communication issues, and functional conflicts between modules


  • 3. End-to-End (E2E) Testing:




  1. End-to-end testing involves testing the complete flow of a user's interaction with the software application from start to finish.
  2. The focus is on testing the software's functionality, data integrity, and communication across different systems or components as a user would experience it.

  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...
