questions:
  - description: Are software tests important?
    choices:
      - Yes, they help others understand the code
      - Yes, they can help to ensure that the software works as expected and can run automatically to ensure project stability
      - No, test must be written and this takes a lot of time 
    hint:
    explanation: Running tests are crutial in all software phases. 
    correctChoice: 1
  - description: What is a unit test?
    choices:
      - It is a collection of tests to be run by the build server
      - It is a piece of code that executes a specific functionality in the code to be tested and asserts a certain behavior or state
      - It messures the performance of methods and classes
    hint: 
    explanation: 
    correctChoice: 1
  - description: What are integration tests?
    choices:
      - They test the behavior of a component or the integration between a set of components
      - They integrate unit tests into the build system
      - They test the behaviour of each component separately
    hint: 
    explanation: Integration tests check that the whole system works as intended, therefore they are reducing the need for intensive manual tests. 
    correctChoice: 0
  - description: Are performance tests relevant?
    choices:
      - They are only relevant if the software is designed to be run on a virtual server
      - They are relevant to messure the development time of software components
      - They are important to evaluate the impact of the code even if it is under high load
      - They are only important for software which communicates with a DB
    hint: 
    explanation: Performance tests are used to benchmark software components repeatedly. 
    correctChoice: 2
  - description: Do software tests need a certain naming convention to work properly?
    choices:
      - Yes, tests should always have the Test suffix at the end of the test classes names
      - Yes, the word 'should' should always be used in the the test classes names
      - Yes, test classes names should be like this, given[ExplainYourInput]When[WhatIsDone]Then[ExpectedResult]
      - No, you can choose your prefered naming convention
    hint: 
    explanation: With the JUnit5 testing framework this convention is less important, as you can use the @DisplayName annotation to add a description for the test method.
    correctChoice: 3
  - description: What is a mock object?
    choices:
      - It supports creating a dummy implementation for an interface or a class, which allows to define the output of certain method calls
      - It is the result of a performance, integration or unit test
    hint: 
    explanation: You can create mock objects manually (via code) or use a mock framework to simulate these classes.
    correctChoice: 0
  - description: What is JUnit?
    choices:
      - It is a popular proprietary test framework
      - It is a popular open source test framework 
      - It is a Java Version that works best with tests
    hint: 
    explanation: JUnit is hosted at Github
