testPersonEquality does not test object equality and can never fail.
Two concrete issues:
-
Trivially-true assertion:
Assert.assertEquals(p1.getEmail(), p2.getEmail())only compares two identicalStringliterals — it will always pass regardless of whetherPersonimplementsequals()/hashCode()correctly. This gives false confidence. -
Wrong
assertEqualsargument order: JUnit convention is(expected, actual). Both arguments here are computed values, so a failure message would be unhelpful.
To meaningfully test equality, assert on the Person objects directly (if equals() is implemented) or at minimum fix the argument order and rename the method to reflect what is actually being tested:
🐛 Proposed fix
- `@Test`
- public void testPersonEquality() {
-
- Person p1 = new Person();
- p1.setEmail("[email protected]");
-
- Person p2 = new Person();
- p2.setEmail("[email protected]");
-
- Assert.assertEquals(p1.getEmail(), p2.getEmail());

The test name testPersonEquality is misleading because it only compares email fields rather than testing object equality (using equals() method). Consider renaming to testPersonEmailEquality or testGetEmailReturnsCorrectValue to accurately reflect what is being tested.

Typo: "testLasrName%d" → "testLastName%d"
The misspelled last-name template will be stored in the persons map and could cause test assertions on lastName fields to fail unexpectedly.
🐛 Proposed fix
- newPerson.setLastName(String.format("testLasrName%d", count));
+ newPerson.setLastName(String.format("testLastName%d", count));📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

setInitPeople() is a disconnected side effect and should be called at bean initialization, not inside getPeople
The person list returned by getPeople contains "[email protected]" entries built inline; the setInitPeople() call on line 56 populates persons (the backing map) with entirely different "[email protected]" entries. These two data sets are never reconciled, so:
- The objects returned to callers are never stored in
persons, making them unreachable viagetByEmail/checkPersonByEmail. setInitPeople()runs on everygetPeopleinvocation — wasteful, even ifputIfAbsentkeeps it idempotent.
The idiomatic Spring pattern is to annotate setInitPeople() with @PostConstruct so the backing store is populated exactly once after dependency injection completes, rather than as a side effect of a request-scoped method.
♻️ Proposed fix — move initialization to `@PostConstruct`
+import javax.annotation.PostConstruct;
...
+ `@PostConstruct`
public void setInitPeople() {
for (int count = 1; count <= 10; count++) {
...
}
}
public Collection<Person> getPeople(int page, int pageSize) {
Collection<Person> person = new ArrayList<>(pageSize);
for (int index = 0; index < pageSize; ++index) {
person.add(new Person(
String.format("person+%[email protected]",
(pageSize * (page - 1) + index + 1))));
}
- setInitPeople();

Missing validation for page and pageSize can produce malformed email addresses
With page = 0 the expression pageSize * (page - 1) + index + 1 evaluates to a negative number, producing strings like "[email protected]". Callers of this integration-test endpoint can easily pass page = 0 by accident.

addPerson(String email) validates the input but never persists the new Person to the backing store
The single-argument addPerson creates and returns a Person without calling persons.putIfAbsent. This is inconsistent with the three-argument overload (lines 94–111) which does store the person. The REST endpoint at line 47–48 of PeopleRestService.java exposes this method via a @PUT /people operation, meaning any HTTP PUT request returns a person that is immediately invisible to getByEmail, checkPersonByEmail, and removePerson.
🐛 Proposed fix — persist the person (mirroring the 3-arg overload)
public Person addPerson(String email) {
if (email == null || email.isEmpty()) {
throw new IllegalArgumentException("Email cannot be null or empty");
}
- return new Person(email);
+ final Person person = new Person(email);
+ if (persons.putIfAbsent(email, person) != null) {
+ throw new PersonAlreadyExistsException(email);
+ }
+ return person;
