@Test创建新记录

Question

I recently started to using Junit. So im newbie.

When i use @Test anotation above method and run that with method with Junit. It creates a new record. Is this normal or am i making a mistake?

    @Before
public void setUp() {
    restTemp = new RestTemplate();
}

@Test
public void testCreateOwner() {
    Owner owner = new Owner();
    owner.setFirstName("new");
    owner.setLastName("record");
    URI location = restTemp.postForLocation("http://localhost:8080/rest/owner", owner);

    Owner owner2 = restTemp.getForObject(location, Owner.class);
    MatcherAssert.assertThat(owner2.getFirstName(), Matchers.equalTo(owner.getFirstName()));
    MatcherAssert.assertThat(owner2.getLastName(), Matchers.equalTo(owner.getLastName()));
}

My create owner method is

@RequestMapping(value = "/owner", method = RequestMethod.POST)
public ResponseEntity<URI> createOwner(@RequestBody Owner owner) {
    try {
        petClinicService.createOwner(owner);
        Long id = owner.getId();
        URI location = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}").buildAndExpand(id).toUri();
        return ResponseEntity.created(location).build();
    } catch (Exception e) {
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }
}

and my createOwner method impl is

public void create(Owner owner) {
    owner.setId(new Date().getTime());
    ownersMap.put(owner.getId(), owner);

}

Thank you for your help.

You are testing the persistence and it is working normal. However I would suggest deleting the entries that you created in your test, either in the test method or creating a separate method (in which you delete) and annotate it with @After .

For example using this:

 @Before
 @After
 public void deleteTestUsers(){
    // call delete endpoint
 }

Using such a snippet you make sure that

• Before running the test you got a "known" state - meaning that the entry does not exist.
• After running the test you clear up the created entry - hence leaving it in a "known" state.

Kind of like the public toilet. - Clean before & clean after. ;-)
