junit Testing

[Zirhi]

So I am writing a test file for a program.

The instruction requires me to use:
import static org.junit.Assert.*;
import org.junit.Test;

However, when I get an error: The import org.junit cannot be resolvedJava(268435846)

Please what is this issue and how do I go about resolving it.

@Zirhi Could you share your sample project here?

[Zirhi]

Hi, do you want only the test file? I am not allowed to share the project on public sites as it is a school assignment

[yaohaizh]

@Zirhi Do you have add the junit as the project dependency?

[Zirhi]

The assignment doesn't specify, but if it helps I think I can do that.

#501

[Zirhi]

So I tried the procedure from the provide gif in #501

I created a lib folder and used the command user$ cp ../lib/*.jar lib/

Returned
cp: ../lib/*.jar: No such file or directory

[Zirhi]

or is that not what solves my problem

[Zirhi]

Issue has been resolved

[fbricon]

So what solved it?

[Zirhi]

I downloaded these two files from junit.org/junit4/

https://github.com/junit-team/junit4/wiki/Download-and-Install

Seems to get rid of the resolving error

[Zirhi]

So I do not get the red line error on my import statements anymore, but on compiling the program I still get this error:

TestOne.java:1: error: package org.junit does not exist
import static org.junit.Assert.*;

compiling as in calling javac from a terminal? If that's the case, you need to add the jars to the classpath.

 javac –classpath C:\path\to\junit.jar;C:\path\to\hamcrest-core.jar TestOne.Java

and, to run the class:

 java –classpath C:\path\to\junit.jar;C:\path\to\hamcrest-core.jar TestOne

if you're on Mac or Linux, the path separator is :.

If you google about how to set the Java classpath, you'll find alternative ways of doing it like in https://howtodoinjava.com/java/basics/java-classpath/

Now in vscode-java, all that is not necessary, as compilation happens under the hood, and if you installed the Java Debugger extension and/or the Java Test runner, you'll be able to run your code directly from within VS Code, by clicking on "code lenses".
