Questions and Answers

1.

What does your essential kit consist of?
- A.
  
  A Testing Framework
- B.
  
  An Assertion Library
- C.
  
  Stubs
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The essential kit consists of a testing framework, an assertion library, and stubs. This means that all of these components are necessary and included in the essential kit. A testing framework is used to organize and run tests, an assertion library is used to define test assertions and check expected results, and stubs are used to replace certain parts of the system being tested.

2.

What does a testing framework provide you?
- A.
  
  A database free to store your test results
- B.
  
  A clear and scalable bedrock for all of tests
- C.
  
  An error-screening tool
- D.
  
  A library of codes for you to use
Correct Answer
B. A clear and scalable bedrock for all of tests

Explanation
A testing framework provides a clear and scalable bedrock for all tests. This means that it offers a solid foundation on which tests can be built and executed. It provides a structure and set of guidelines for organizing and running tests, making it easier to manage and maintain them. Additionally, a testing framework typically includes various features and functionalities that aid in test automation and reporting, further enhancing the clarity and scalability of the testing process.

3.

Which framework is considered a gold standard?
- A.
  
  Mocha
- B.
  
  Intern
- C.
  
  Chai
- D.
  
  Vows
Correct Answer
A. Mocha

Explanation
Mocha is considered a gold standard framework because it is widely used and highly regarded in the JavaScript testing community. It provides a rich set of features, including support for asynchronous testing, easy setup and teardown of test cases, and a flexible and intuitive syntax. Mocha also has a large and active community, which means that there is extensive documentation, tutorials, and support available for users. Overall, Mocha has proven to be a reliable and powerful framework for writing and running tests, making it the preferred choice for many developers.

4.

Which one of these helps you to write tests?
- A.
  
  Assertion folder
- B.
  
  Assertion file
- C.
  
  Assertion library
- D.
  
  Assertion collection
Correct Answer
C. Assertion library

Explanation
An assertion library is a tool or framework that provides a set of functions or methods to write tests. It typically includes various assertion methods that allow developers to define expected outcomes and compare them with actual results during testing. This helps in ensuring that the code behaves as expected and catches any bugs or errors.

5.

Which syntax style doesn't exist?
- A.
  
  Affirmative
- B.
  
  TDD
- C.
  
  BDD
- D.
  
  Assert
Correct Answer
A. Affirmative

Explanation
The given question asks for a syntax style that does not exist. The options provided are TDD, BDD, assert, and affirmative. TDD and BDD are both well-known syntax styles used in software development, while assert is a keyword used for testing purposes. However, "affirmative" is not a recognized syntax style in programming, making it the correct answer.

Rate this question:
6.

Which library should you use?
- A.
  
  Latte
- B.
  
  Tea
- C.
  
  Ruby
- D.
  
  Chai
Correct Answer
D. Chai

Explanation
The correct answer is Chai because the question is asking which library should be used, and Chai is one of the options provided.

7.

Which function do you need to control in order stub and assert?
- A.
  
  Replay
- B.
  
  Require
- C.
  
  Restart
- D.
  
  Record
Correct Answer
B. Require

Explanation
To stub and assert, you need to control the "require" function. The require function is commonly used in programming to validate inputs or conditions before executing further code. By controlling the require function, you can stub (replace) certain behavior or assert (check) specific conditions within your code. This allows you to test and verify the expected behavior of your program.

8.

Which one of these is a powerful mocking tool?
- A.
  
  Rewire
- B.
  
  Review
- C.
  
  Restart
- D.
  
  Replay
Correct Answer
A. Rewire

Explanation
Rewire is a powerful mocking tool used in software development to simulate and control the behavior of dependencies during testing. It allows developers to replace real objects with mock objects, enabling them to isolate and test specific components of their code without relying on the actual implementation of those dependencies. By using Rewire, developers can easily create and manipulate mock objects, making it an effective tool for writing comprehensive and reliable unit tests.

Rate this question:
9.

What can't you do with Rewire?
- A.
  
  Come up with new commands
- B.
  
  Set private variables
- C.
  
  Inject new code
- D.
  
  Replace old functions
Correct Answer
A. Come up with new commands

Explanation
Rewire is a tool used for unit testing in JavaScript, which allows you to mock and modify the behavior of functions and variables within a module. However, it does not provide the capability to come up with new commands. It can only modify existing functions, set private variables, and inject new code into the module being tested.

What's the most important thing about your testing?
- A.
  
  Detailed results
- B.
  
  Details
- C.
  
  Length
- D.
  
  Clarity
Correct Answer
D. Clarity

Explanation
The most important thing about testing is clarity. This means that the testing process should be clear and easily understandable. Clear testing ensures that all stakeholders, including developers, testers, and clients, can comprehend and interpret the results accurately. It helps in identifying any issues or bugs effectively and allows for efficient communication and collaboration among team members. Clarity in testing also ensures that the testing objectives and requirements are well-defined and that the testing process is transparent and reliable.
