The method assertEquals(String, String) is undefined for the type TestJunit

Question

I am new to JUnit. I just started working on JUnit and i am getting following error.

The method assertEquals(String, String) is undefined for the type TestJunit

and my Javacode:

import org.junit.Test;
import static org.junit.Assert.assertArrayEquals;

public class TestJunit {

    String message = "Hello World";
    MessageUtil messageutil = new MessageUtil(message);

    public void testPrintMessage()
    {
        assertEquals(message,messageutil.printMessage());

    }
}

please help me resolve this issue.

Answer 1

You imported

import static org.junit.Assert.assertArrayEquals;

but not

import static org.junit.Assert.assertEquals;

You could also import every static member of Assert with

import static org.junit.Assert.*;

Without these, Java thinks you are calling the method assertEquals defined in the class the code is declared in. Such a method does not exist.

如果导入不起作用，请在运行代码之前尝试保存
