I'd like to write a simple constraint for mandatory lunch breaks.
I use the ConstraintCollector "toList" in my groupBy like so:
public Constraint lunchBreak(ConstraintFactory constraintFactory) {
return constraintFactory.from(TimetableEntry.class)
.groupBy(TimetableEntry::getPlanningDay, TimetableEntry::getSchoolClass, toList())
.filter((day, schoolClass, entries) -> {
if (entries.size() == 7) {
List<TimetableEntry> freePeriods = entries.stream().filter(
timetableEntry -> timetableEntry.getSubject().getId() == 1L).collect(Collectors.toList()
);
if (freePeriods.size() > 0) {
return false;
}
return true;
}
// todo logic for 8 hours
// todo logic for 9 hours
// todo logic for 10 hours
return false;
})
.penalize("A 7-hour-day must have a lunch break somewhere",
ConstraintConstants.MANDATORY_LUNCH_BREAK_CONFLICT);
}
When I test the constraint (Note that entries is a Set)
this.constraintVerifier.verifyThat(TimetableConstraintProvider::lunchBreak)
.given(entries.toArray())
.penalizesBy(1);
I get a "java.lang.ClassCastException: class TimetableEntry cannot be cast to class java.util.List". I am confused as to why that is because the GroupBy works with a count() just fine but I need the grouped list.
When I instead test with
this.constraintVerifier.verifyThat(TimetableConstraintProvider::lunchBreak)
.given(entries)
.penalizesBy(1);
The groupBy + the filter is not firing.
As a comment states, the Test should look like this
constraintVerifier.verifyThat(TimetableConstraintProvider::lunchBreak)
.given(entries.toArray())
.penalizesBy(0);
However, the groupBy looks fine, and i cannot find what is causing the error. The following is somehow not causing an error, but i don't understand why. Note the first group by which is doing basically nothing, but removing it causes an error:
public Constraint lunchBreak(ConstraintFactory constraintFactory) {
return constraintFactory.from(TimetableEntry.class)
.groupBy(timetableEntry -> timetableEntry)
.groupBy(TimetableEntry::getPlanningDay, TimetableEntry::getSchoolClass, toList())
.filter((day, schoolClass, entries) -> {
// some logic
})
.penalize("A school class must have a lunch break after 6 hours",
ConstraintConstants.MANDATORY_LUNCH_BREAK_CONFLICT);
The stack trace of the error when the first group by is missing:
java.lang.RuntimeException: java.lang.ClassCastException: class ase.tito.entity.TimetableEntry cannot be cast to class java.util.List (ase.tito.entity.TimetableEntry is in unnamed module of loader 'app'; java.util.List is in module java.base of loader 'bootstrap')

I'm writing some tests to check that some textures are the same when loading. I am unsure what is wrong, as i'm getting an error I have never seen before. There might be some error in my assertEquals statement, but I myself can't see it.
I have not written many JUnit tests so far, so there might just be that i'm making it too simple and that I need to add more code.
org.opentest4j.AssertionFailedError: expected: com.badlogic.gdx.graphics.Texture#415b0b49<spider.png> but was: com.badlogic.gdx.graphics.Texture#6d5620ce<spider.png>
Expected :spider.png
Actual :spider.png

#BeforeEach
void setUp(){
map = new TmxMapLoader().load("assets/data/GameBoard.tmx");
p1 = new Player(new Sprite(new Texture("weirdguy2.0.png")), (TiledMapTileLayer) map.getLayers().get(0));
enemy = new Enemy(new Sprite(new Texture("spider.png")), (TiledMapTileLayer) map.getLayers().get(0));
mm = new MainMenu(game);
}
#Test
void testMainMenuTexture(){
assertEquals(new Texture("AgameStart.png"), mm.startButtonActive);
assertEquals(new Texture("AgameStartInactive.png"), mm.startButtonInactive);
assertEquals(new Texture("quit.png"), mm.quitButtonActive);
assertEquals(new Texture("quit.png"), mm.quitButtonInactive);
}
The assertEquals method checks whether two objects are equal using the Object.equals method. This method is often overwritten in a class to check whether two instances of the class are equal, but if it's not overwritten, this method will just check whether the objects are the same instance.
Since the libgdx class Texture doesn't overwrite the equals method your test asserts that both objects are the same instance, but not that they contain the same pixel data.
A solution would be to implement a new method areTexturesEqual(Texture t1, Texture t2) that checks whether the textures are equal:
#Test
public void test_texturesEqual() {
// replace assertEquals(new Texture("file_name.png"), yourObject); with the following line
assertTrue(areTexturesEqual(new Texture("file_name.png"), yourObject));
}
private boolean areTexturesEqual(Texture t1, Texture t2) {
//TODO check the pixel data, or whatever you need to check to consider two textures 'equal'
}
I'm trying to query an embedded Derby database located inside a JAR file I created. I believe the program is successfully able to locate the database, however it just fails to start. I know Derby supports accessing a database located inside a JAR because Apache provides documentation on this. I have followed their instructions, but still this error persists.
Every time I try to query said DB, I receive this error code:

Here is my code:

System.out.print(cachedRowSet.getFloat("salary") + " ");
System.out.println(cachedRowSet.getString("filingStatus"));

I'm figuring out how to work with Mockito and Junit and now testing some snippets. I don't understand why I have NPE in the following code after Mock annotation:
#RunWith(MockitoJUnitRunner.class)
public class MockitoTest{
#Test
public void whenNotUseMockAnnotation() {
List mockList = mock(ArrayList.class);
mockList.add("one");
verify(mockList).add("one");
assertEquals(0, mockList.size());
when(mockList.size()).thenReturn(100);
assertEquals(100, mockList.size());
}
#Mock
List <String> mockedList;
#Test
public void whenUseMockAnnotation() {
mockedList.add("one");
verify(mockedList).add("one");
assertEquals(0, mockedList.size());
when(mockedList.size()).thenReturn(100);
assertEquals(100, mockedList.size());
}
}
But the first part of the code works fine, although as far as I understand both parts are doing the same.
EDITED:
the stack trace:

Replace
#RunWith(MockitoJUnitRunner.class)
With
#ExtendWith(MockitoExtension.class)
It works like a charm.
#RunWith is for Junit4 whereas #ExtendWith is for Junit5.
I'm getting a NullPointerException while trying to set a variable using Reflection in a Test class.
Cities.java initializes filename from application.properties using #Value annotation
CitiesTest.java is supposed to initialize filename through Reflection, instead I get a NPE.
What am I doing wrong ?
Cities.java
#Component
public class Cities
{
private final List<City> cities;
#Value("${filename.Cities}")
private String filename;
public Cities(Gson gson)
{
this.gson = gson;
this.cities = generateCities();
}
private List<City> generateCities()
{
List<City> cities = new ArrayList<>();
try (
Reader reader = new InputStreamReader(Cities.class.getResourceAsStream("/" + filename))
)
{
Type listType = new TypeToken<ArrayList<City>>() {}.getType();
cities = gson.fromJson(reader, listType);
}
catch (IOException e)
{
logger.severe("Failed to read file. Error: " + e);
}
return cities;
}
}
CitiesTest.java
#TestPropertySource(properties = {"filename.Cities=cities.json"})
class CitiesTest
{
Cities cities;
#BeforeEach
public void setUp()
{
cities = new Cities(new Gson());
setField(cities, "filename", "cities.json");
}
#Test
void isCityTest2()
{
assertFalse(cities.isCity("USA"), "City not found in localDbase");
}
}

it looks like generateCities() is called before you try to override 'filename' using reflection (setField() method?), where filename attribute is null causing the NPE.
If you want to define filename during your unit testing you could include that in the constructor of Cities so you can set the desired value when you create the object in #BeforeEach.
Another option is to let Spring create Cities so in your unit testing filename is defined with the value in application.properties (which you can customise using profiles if needed).
