Enhancing the readability of tests
Release date: Jan 11, 2021
Enhancements to readability of long arrange sections
It can often be challenging to follow the creation of large and complex objects in the arrange section of tests. The arrange section has been enhanced to make the setup more representative of a human written test.
@Test
public void testShowOwner2() throws Exception {
// Arrange
Owner owner = new Owner();
owner.setLastName("Doe");
owner.setPetsInternal(new HashSet<Pet>());
owner.setFirstName("Jane");
PetType petType = new PetType();
petType.setName("Dog");
Pet pet = new Pet();
pet.setOwner(owner);
pet.setVisitsInternal(new ArrayList<Visit>());
pet.setName("Bella");
pet.setType(petType);
HashSet<Pet> petSet = new HashSet<Pet>();
petSet.add(pet);
Owner owner1 = new Owner();
owner1.setLastName("Doe");
owner1.setPetsInternal(petSet);
owner1.setFirstName("Jane")
...
}
