Questions and Answers

Black-box testing is done without any special internal knowledge of the product being tested. Which of the following is the best description of a functional test in black-box testing?

  • Testing the performance and scalability of the software under different conditions.
  • Testing the software's compliance with regulatory standards.
  • Testing specific functions of the code to ensure they perform as expected based on requirements.
  • Testing the software's user interface for usability issues. (correct)
  • Non-functional tests are an important part of black-box testing. Which of the following is an example of a non-functional test?

  • Testing if the login functionality works correctly.
  • Testing if the system can handle a high number of concurrent users. (correct)
  • Testing if a new feature has introduced any bugs in the existing software.
  • Testing if the correct error message is displayed when a user inputs invalid data.
  • Regression tests ensure that new code changes do not negatively affect the existing functionality of the software. Which of the following is the best example of a regression test?

  • Testing the speed of the software's response to user inputs.
  • Testing all the features of the software after a new update to make sure everything still works as before. (correct)
  • Testing the software's compatibility with different operating systems.
  • Testing the security of the software against unauthorized access.

    Study Notes

    Software Testing Goals

    • The goal of validation in software testing is to ensure the software does what the user wants.

    Test-Driven Development (TDD)

    • In TDD, the 'Red' phase involves writing tests that the code should pass.

    Testing Methods

    • Black-box testing is a method that involves designing tests without any knowledge of the internal structure of the code.
    • There are other testing methods, including White-box testing and Gray-box testing.

    Equivalence Class Partitioning

    • The purpose of equivalence class partitioning in testing is to divide inputs into subsets that are expected to be treated similarly by the code.
    • This helps to identify boundary values for testing.

    White-Box Testing Metrics

    • White-box testing metrics include:
      • Statement coverage
      • Decision coverage
      • Path coverage
    • Boundary value analysis is not a metric used in white-box testing.
