Which type of software testing ensures that integrated

Solution

Integration Testing evaluates the interaction between integrated software modules. This phase comes after Unit Testing and ensures that modules communicate correctly with each other, such as verifying API responses or database interactions. Integration Testing can be performed in various approaches, such as top-down, bottom-up, or a hybrid approach.

1. Importance: Integration Testing is crucial for systems with multiple interdependent components, like e-commerce platforms.
2. Example: Testing how a login module interacts with the user database.
3. Tools Used: Tools like JUnit or Postman for API integration are widely used.

• Unit Testing: Tests individual modules, not interactions.
• Regression Testing: Checks existing functionality after changes.
• Load Testing: Measures system performance under load, unrelated to integration.
• UAT: Ensures the application meets user requirements, not module interactions.
