25.11. Parameterized Tests

Try these first

1. 1.

   What annotation do you use for a parameterized test?

   Hint

   Think about which annotation indicates a test runs multiple times.

2. 2.

   Name a source annotation that can provide parameters for a test.

   Hint

   Consider what type of source can provide single arrays of values.

3. 3.

   What does @ParameterizedTest do in JUnit?

   • Runs a test only once
   • Runs a test multiple times with different parameters
   • Runs multiple tests simultaneously

   Hint

   Remember how parameterization allows multiple values.

4. 4.

   True or False: Parameterized tests are only useful for numerical data.

   • True
   • False

   Hint

   Consider the applications of parameterized tests beyond just integers.

5. 5.

   Create a parameterized test using @CsvSource to check for valid email formats.

   Hint

   Consider how you would define valid and invalid email scenarios.

6. 6.

   Design a parameterized test for a method that checks for palindromes with a variety of inputs.

   Hint

   Think about what constitutes a palindrome, and how string manipulation can validate it.
