The import org.junit cannot be resolved (VSCode)

[cybersinger]

I can't use JUnit test framework with VSCode, get message "The import org.junit cannot be resolved". I tried:

1. Installed all recommended Java extension and then some more.
2. Downloaded junit-platform-console-standalone-1.7.0-M1 jar file and pointed settings.json to it.
3. Created new Java project through Project Manager for Java extension.
4. Consulted documentation on junit.org, unfortunately, I couldn't make much of it, as instructions use terms that I am not familiar with.

Environment

• Operating System: Windows 10 Pro (10.0.19042)
• JDK version: AdoptOpenJDK 11.0.9.1-hotspot
• Visual Studio Code version: 1.52.1
• Java extension version: 0.12.1
• Java Debugger extension version: 0.1.5

Steps To Reproduce

1. created simplest possible program with @test line.

package prvenac;

import static org.junit.Assert.assertTrue;
import org.junit.Test;
public class AppTest 
{
    @Test
    public void shouldAnswerWithTrue()
    {
        assertTrue( true );
    }
}

(I am new to GitHub and I probably didn't document this issue properly. I uploaded the files manually.)

Current Result

The import org.junit cannot be resolved.

Expected Result

My understanding is that the extensions I installed should enable very simple use of junit, i.e. my code above should work?

Additional Informations

The JUnit dependency defined in pom.xml is JUnit 4, and the junit-platform-console-standalone-1.7.0-M1.jar is for JUnit 5. If you want to play with JUnit 4, I think there is no need to download other jars given your pom configuration

Thanks for comment jdneo! I don't mind which release it would be, so I downloaded junit-4.11 to a folder included in Windows "Environmental Variables". Meanwhile I reset "settings.json" file, and don't know whether I should specify the path to junit .jar there, and if yes how to do it? Restarted VSCode, but it still doesn't work. Can you please bear with me, solution is probably very simple, but I spent hours searching for it.

Ok, so I suppose you are not using the Maven as the project build tool. But just want to try some test features in a very simple folder. Here is what you can do. (taking the Junit 5 as an example)

1. Create a new Java Project using Project Manager for Java extension
   

2. Copy the jar file junit-platform-console-standalone-1.7.0-M1.jar into the lib folder
   

Then you can start to write your test cases.

Note: Basically, there is no need to do some other configurations because the Java Language Server will by default consume the jars in the lib folder as the project dependency for the project without any build tools.

The issue, I believe, is that you need to make sure the file is under the test folder.

Yes, its work for me. Thank you. Pascal
