My tests are being ignored in IntelliJ.

Hey, I'm trying ouy Java with spring boot. I have a simple guess the word game, with the word being a cocktail that is retreived with an API. User inputs their guess, and dpeending whether or not they are correct they can try again or quit. I wanted to write some tests and ran into a problem that my tests have the ignored status for whatever reason. The below code for example should test for the getcocktail method being called once for example. Tried googling but little info on the issue.

import com.google.gson.JsonObject;
import com.ridango.game.ApiService;
import com.ridango.game.GameService;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.util.Scanner;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.mockito.Mockito.*;

public class GameServiceTest {

    @InjectMocks
    private GameService gameService;

    @Mock
    private ApiService apiService;

    @Mock
    private Scanner scanner;

    @BeforeEach
    public void setUp() {
        MockitoAnnotations.openMocks(this); // Initialize mocks
    }

    @Test
    public void testStartGameCorrectGuess() {
        JsonObject mockCocktail = new JsonObject();
        mockCocktail.addProperty("strDrink", "Margarita");
        when(apiService.GetCockTail()).thenReturn(mockCocktail);
        String simulatedInput = "Margarita\nno\n";
        InputStream inputStream = new ByteArrayInputStream(simulatedInput.getBytes());
        System.setIn(inputStream);
        gameService.StartGame();

        verify(apiService, times(1)).GetCockTail();
    }
}

        verify(apiService, times(1)).GetCockTail();
    }
}

Where does the "You guessed right" text etc come from? Can you run "all tests" in some way instead of running the specific test method? Can you try using a debugger?

JavaBot•3mo ago

It looks like you are having issues with debugging or issues that can be solved using a debugger. Check out this article on dev.java to see how debugging works and how to use a debugger. This Stack Overflow question and its answers also explain debugging in general. These links describe how to use the debugger in some IDEs: • Debugging in IntelliJ • Debugging in Eclipse

LuxenbauOP•3mo ago

This comes up when I run the test. This is actually the sysouts inside of the game, but they are triggered when I run the test... Im new to UnitTesting ... And I tried running the entire file, or all tests, its the same thing. Tests are ignored

dan1st•3mo ago

Do you have both JUnit 4 and 5 on the classpath?

LuxenbauOP•3mo ago

You mean in gradle? I have for tests:

    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }

    testImplementation 'org.mockito:mockito-core:5.13.0'

    testImplementation 'net.bytebuddy:byte-buddy:1.15.1'

    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }

    testImplementation 'org.mockito:mockito-core:5.13.0'

    testImplementation 'net.bytebuddy:byte-buddy:1.15.1'

JavaBot•3mo ago

Please format your code to make it more readable. For java, it should look like this:

```java
public void foo() {
 
}
```

```java
public void foo() {
 
}
```

dan1st•3mo ago

weird

LuxenbauOP•3mo ago

yes I have no clue why =/

dan1st•3mo ago

In your screenshots, there are a few icons above the test results see the tick icon?

LuxenbauOP•3mo ago

You mean the show only passed tests icon?

dan1st•3mo ago

sure it's passed only? What happens when enabling it?

LuxenbauOP•3mo ago

The tick mark is the show passed. The crossed o is the show ignored

dan1st•3mo ago

yes I know

LuxenbauOP•3mo ago

nothing. if i disable the show ignored, the Test Results disappear from the left pane

dan1st•3mo ago

ok Can you try making the test fail in some way? by temporarily changing some code if you do that, does it still show as disabled?

LuxenbauOP•3mo ago

I tried changing verify to some ridiculous number but it still gets ignored

john•3mo ago

a simple test like: @Test

    public void testIntegerEquality() {
        int expected = 5;
        int actual = 2 + 3; // This could be a result from your service method

        assertEquals(expected, actual, "The actual value should match the expected value.");
    }

    public void testIntegerEquality() {
        int expected = 5;
        int actual = 2 + 3; // This could be a result from your service method

        assertEquals(expected, actual, "The actual value should match the expected value.");
    }

however works

LuxenbauOP•3mo ago

so its something with the test

dan1st•3mo ago

so other tests work as expected? Can you try making the problematic test fail?

LuxenbauOP•3mo ago

if i write tests that do not touch the GameService class. I think its something with it

dan1st•3mo ago

Did you use @Ignore or @Disabled in the past? Can you step through the test with a debugger? Does anything in it throw any exception?

the warnings should not be affecting the test at all. maybe i mocked it somehow wrong but it just gets ignored for whatever reason

dan1st•3mo ago

LuxenbauOP•3mo ago

those are results of the debugger? you mean the one at top right of IntelliJ?

dan1st•3mo ago

No. That's just stdout and stderr

JavaBot•3mo ago

dan1st•3mo ago

I am talking about actually stepping through the code

LuxenbauOP•3mo ago

hold on need to figure out how this works

LuxenbauOP•3mo ago

so this is when i break at inputstream

dan1st•3mo ago

can you step over the lines in your test one after the other? Is there anything throwing an exception?

LuxenbauOP•3mo ago

hmm, when i set breakpoint at the verify line, test is already ignored

dan1st•3mo ago

maybe something in your code exits in some way Are you using System.exit() anywhere?

LuxenbauOP•3mo ago

hmm, the exitgame method uses it yes wait, does it exit the application and test?

dan1st•3mo ago

that kills all tests

LuxenbauOP•3mo ago

no way let me check this

dan1st•3mo ago

there are maybe some ways around it but it's annoying

LuxenbauOP•3mo ago

wow, i just temp disabled it and now it passes i did not know the sysexit also affects the test...

dan1st•3mo ago

tests are also just java programs

LuxenbauOP•3mo ago

and it terminate the jvm right

dan1st•3mo ago

kinda yes

LuxenbauOP•3mo ago

ooohhhh, so now i need to figure out how to write tests, since my default public method calls it thanks for the help man

dan1st•3mo ago

The best way is not using System.exit() in your code

LuxenbauOP•3mo ago

hmm well need to close the program somehow without throwing exceptions then. i mean its a standalone program so sysexit seems to make sense

dan1st•3mo ago

if you can't do that, you might be able to mock System.exit well in your application you probably have some sort of loop checking for input etc you could also make sure that stops

LuxenbauOP•3mo ago

yea i do have a while loop

dan1st•3mo ago

you could also make sure that loop stops looping when you want to exit

LuxenbauOP•3mo ago

yeah, i think so.

Scanner scanner = new Scanner(System.in);
        boolean keepPlaying = true;
        while (keepPlaying) {
            String cocktailName;
            revealedKeys.clear();

Scanner scanner = new Scanner(System.in);
        boolean keepPlaying = true;
        while (keepPlaying) {
            String cocktailName;
            revealedKeys.clear();

i insta call exit game whenever user exits or says no. i can just cancel the loop instead. wont exit the app but i can get the tests working can instead just change the keepplaying value most importantly i now know the issue 😄 thanks a lot man idk if i can give u rep or karma here or something @dan1st | Daniel
