Can you show your pom.xml/build.gradle?

specifically I'm interested in your JUnit dependencies including their versions

though this seems like it could be an IntelliJ issue - can you try running these tests from the command-line?

[rich dove]

how do I do that?

[rich dove]

that does not exist

https://hastebin.com/share/qakoxicuxa.xml

[cedar nymph]

run mvn test

[cedar nymph]

Why do you have both JUnit 4 and JUnit 5 in your pom.xml?

[rich dove]

i am unsure, i think intellij auto installed because i highlighted over the error and pressed install junit and then the errors went away

[rich dove]

should I delete JUnit 5?

[cedar nymph]

In the imports of your test classes, do you have org.junit.Test or org.junit.jupiter.api.Test?

[cedar nymph]

yeah you don't have Maven installed

I think if your press ctrl in IntelliJ twice, it should show a box with Run anything

[cedar nymph]

first find out which of them you are using

[cedar nymph]

in that box, you should be able to type mvn test

[rich dove]

yep, that did something

[rich dove]

yeah

package com.example.proj3;

import static org.junit.Assert.*;
import static org.junit.jupiter.api.Assertions.assertFalse;
import static org.junit.jupiter.api.Assertions.assertTrue;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;```

[cedar nymph]

ok so you are mixing JUnit 4 and JUnit 5 in your test

which one do you want to use?

You need to decide for one

[rich dove]

well i did not write this JUnit file, it was given as code to use to test my project

i guess 4, since it's more stable

if i wanted to keep 4, what would I do?

[cedar nymph]

then you need to remove all the org.junit.jupiter stuff

[rich dove]

if I do that, will i be able to use:

    @BeforeEach
    public void setUp() throws Exception {
    }```

[cedar nymph]

both from the test and the pom.xml

[cedar nymph]

that's what @Before does

[rich dove]

then this

[cedar nymph]

replace the @BeforeEach by @Before

[rich dove]

ah, it works now

thank you!
