Cannot find symbol assertEquals

Question

I\'m trying to write my first unit tests for a calculator, but NetBeans says it can\'t find the symbol assertEquals and annotation @Test.
Should i

Answer 1

I was having the same problem cannot resolve symbol Assert i have tried these solutions by adding the different import from the different answers.

1. import org.junit.Assert;
2. import static org.junit.Assert.*;
3. import static org.junit.Assert.assertEquals;
4. import static org.junit.jupiter.api.Assertions.*;
5. import org.junit.Assert;

but the solution that did the magic was just place the junit-4.12.jar in the app\lib ditectory and just build the project, and import like this

import org.junit.Assert;

you can download the junit-4.12.jar from here
