What is the difference between Black-Box and White-Box Testing?

 

  • Black-Box Testing: This approach focuses on testing the functionality of an application without knowing its internal structure or code. Testers provide input and analyze the output without understanding how the system processes it. For example, testing a login page by entering credentials and verifying the expected response.
  • White-Box Testing: Unlike black-box testing, white-box testing requires knowledge of the application's internal workings. Testers evaluate the internal logic, code structures, and data flows while performing functional testing. This method is commonly used for unit testing and verifying code efficiency.

    Explain API with an example.

     An Application Programming Interface (API) allows two systems to communicate and exchange data. For instance, when registering on Amazon, users may have the option to sign up using their Google or Facebook credentials. Amazon requests personal information from Facebook. Facebook retrieves and validates the user’s details (such as email and name) from its database. Facebook sends the verified data back to Amazon, allowing the registration process to proceed seamlessly. Popular API testing tools include Postman and SoapUI , which are used for validating API requests and responses.

    When do you automate a test case?

     Test cases are automated when they meet the following criteria: Repetitive execution is required across multiple releases or test cycles. High-risk areas of the application need frequent validation. Test cases with complex workflows that are time-consuming for manual execution. Performance, load, or regression testing needs automation for efficiency. Stable functionalities where application behaviour is not frequently changing.
