1.
What does JUnit test accelerate?
Correct Answer
A. Speed
Explanation
JUnit tests accelerate the speed of the testing process. By automating the testing process, JUnit allows for quick and efficient execution of tests, which helps in identifying errors and bugs in the code. It saves time by providing immediate feedback on the correctness of the code, reducing the time required for manual review and debugging.
2.
What's JUnit part of?
Correct Answer
D. XUnit
Explanation
JUnit is a testing framework for Java applications. It is a part of the xUnit family of testing frameworks, which includes various frameworks for different programming languages. JUnit specifically focuses on unit testing, which involves testing individual units of code to ensure their correctness. It provides a set of annotations, assertions, and test runners that help in writing and executing tests effectively. Therefore, JUnit is a part of the xUnit family and is commonly used for testing Java applications.
3.
What's JUnit used for?
Correct Answer
D. Writing and running tests
Explanation
JUnit is a popular Java testing framework used for writing and running tests. It provides a set of annotations, assertions, and test runners that allow developers to easily create and execute unit tests for their code. With JUnit, developers can write test cases to verify the correctness of their code and ensure that it behaves as expected. The framework also helps in identifying errors and failures during the test execution, making it a valuable tool for test-driven development and ensuring code quality.
4.
What does JUnit allow you while writing tests?
Correct Answer
C. Faster writing
Explanation
JUnit allows developers to write tests more quickly. It provides a framework that simplifies the process of writing and executing tests, allowing developers to focus on the actual test logic rather than the setup and teardown code. It provides various annotations and APIs that make it easier to write tests, such as the @Test annotation to mark a method as a test case, and assertion methods to check the expected results. This helps in increasing productivity and efficiency while writing tests.
5.
What color is the test progress bar if the test is running smoothly?
Correct Answer
C. Green
Explanation
The test progress bar is green if the test is running smoothly. This suggests that green is the color used to indicate successful progress or completion in this context.
6.
Which color shows the test failure?
Correct Answer
A. Red
Explanation
Red is commonly associated with danger, warning, and failure. In the context of testing, red is often used to indicate a failed test. When a test fails, it means that the expected result did not match the actual result, indicating a problem or error in the system being tested. Therefore, red is the color that shows the test failure.
7.
What's Unit Test Case?
Correct Answer
C. It's a part of code
Explanation
A unit test case is a part of code that is used to verify the functionality of a specific unit of code, such as a method or function. It is written to test a small, isolated piece of code to ensure that it is working correctly. Unit test cases are typically written by developers to ensure that their code meets the expected requirements and to catch any potential bugs or errors.
8.
What does Unit Test Case ensure?
Correct Answer
D. It ensures that another part of code works as expected
Explanation
A unit test case is designed to test a specific unit or component of code in isolation to ensure that it functions as expected. It verifies that the individual unit of code is working correctly and producing the desired output. Therefore, the correct answer suggests that a unit test case ensures that another part of the code, which is being tested, works as expected.
9.
What can JUnit tests be organized in?
Correct Answer
C. Suites
Explanation
JUnit tests can be organized in suites. A test suite is a collection of individual test cases or other test suites. It allows for grouping related tests together, making it easier to manage and execute them as a single unit. By organizing tests into suites, developers can efficiently run specific groups of tests, such as those related to a particular module or functionality, and easily identify any failures or issues.
10.
What do you have t have installed before you start running JUnit?
Correct Answer
D. JDK
Explanation
Before running JUnit, you need to have JDK (Java Development Kit) installed. JDK includes the necessary tools and libraries to develop and run Java applications, including JUnit. JUnit is a testing framework for Java, and it requires the Java compiler and runtime environment provided by the JDK to execute test cases and generate test reports. Therefore, JDK is a prerequisite for running JUnit.
