Assessment

Read the question or description and select the best answer to fit that question. If you are not sure, take your best guess.

Question Title

* 1. Your SID

Question Title

* 2. Considering unit testing in Java, what would be the best definition of the unit?

A class

A method

An attribute

A package

Question Title

* 3. Consider the following methods, how many logic paths can you spot?

Question Title

* 4. Select one statement that is NOT true.

Every unit test class contains at least one test method annotated with @Test.

A unit test class is located in the same package in the src/ folder as the class under test.

A unit test class is located in the same package in the test/ folder as the class under test.

Every unit test class should focus only on one class under test.

Question Title

* 5. Considering the F.I.R.S.T acronym describing a good unit test, what does the letter I stand for?

Important - because unit testing is important

Interesting - make the unit tests interesting for the developers coming after you

Inquisitive - every unit test should explore all the possibilities within a method under test

Independent - every unit test should be independent of other tests, a unit test does not rely on an outcome of any other previous tests

Question Title

* 6. What would you typically find in the given part of the unit test?

Execution of the method under test

Comparison of the expected and the actual result

Set up of the test class, the test data or any other objects that are needed for the execution of method under test

Any set up that is required to run before every single unit test

Question Title

* 7. Consider the following method. What would be the best set of test data to test the highlighted logic path?

totalScores = 356, noOfTests = 0, extra = 30

totalScores = 356, noOfTests = 5, extra = 10

totalScores = 356, noOfTests = 7, extra = 10

totalScores = 256, noOfTests = 5, extra = 10

Question Title

* 8. Carefully read the following unit test

What can be said about test method?

There should be more assertions in the then part

The code will not compile

The test will pass since two positive numbers added together give a positive number

The test will not run as the @Test annotation is missing

Question Title

* 9. Select a statement that is correct

We should create as many test methods as necessary to cover all logic paths.

We should create getters and setters when necessary to help us test the values in a class

Private methods cannot be tested.

We should run unit tests every morning before we have a Scrum meeting.

Question Title

* 10. Select one statement that is NOT true about the test coverage

Test coverage should be at least 70%

Always aim for 100% coverage on methods that contain business logic

Test coverage should aways be 100%

Test coverage is a percentage representation of the application code covered by unit tests.

Question Title

* 11. When is the best time to write unit tests?

Simultaneously while you're writing new code or changing existing code base

Before you write any new code or change existing code base

After you've written any new code or changed existing code base

All of the above
