Sample Solution for WS of Unit Testing 2

To be able to raise discussion about possible solutions, I created this merge request

• fixed bug in the constructor

  thanks to the additional boundary tests, we found another bug in the constructor

• add a test for Person constructor with invalid boundary values for its name.

• clean up redundant empty string test

  and rename test method to null test

• add boundary value test for zip code

  using parameterized tests is very handy for this

• rename test method to a more meaningful name

• add person test with invalid zip boundary values

  using parameterized test for bulk data

• removed redundant test

• add person test with valid birthdate boundary values

  for custom types we can use MethodSource concept to generat the required bulk test data

• add person test with invalid bithdate boundary values

  using MethodSource to create birthdate objects. Note: null is also an invalid type, buit cannot be passed as an argument with the Argument Stream. So we use the @NullSource annotation to pass also null as an invalid data for the test.

• remove redundant invalid birthdate test

  this test is now covered with the parameterized test.
