Example showing different ways to assert a text

AssertExamplesTest.java

import static org.testng.Assert.assertEquals;
import static org.testng.Assert.assertTrue;

import org.apache.commons.lang3.StringUtils;
import org.testng.annotations.Test;

public class AssertionTest {

    public static final String ACTUAL = "text wrong here";
    public static final String EXPECTED = "text right here";

    // not recommended
    @Test
    public void usingAssertTrue() {
        assertTrue(ACTUAL.equals(EXPECTED));
    }
 
    // best one
    @Test
    public void usingAssertEqual() {
        assertEquals(ACTUAL, EXPECTED);
    }

    // not recommended
    @Test
    public void usingAssertTrueAndStringUtils() {
        assertTrue(StringUtils.equals(ACTUAL, EXPECTED));
    }
}

Results

usingAssertTrue

The problem here is: the error is not clear as the differences are true or false

java.lang.AssertionError: expected [true] but found [false]
Expected :true
Actual   :false

usingAssertEqual

The good point here is: the error is clear and shows the text differences

java.lang.AssertionError: expected [text right here] but found [text wrong here]
Expected :text right here
Actual   :text wrong here

usingAssertTrueAndStringUtils

The problem here is: the error is not clear as the differences are true or false

java.lang.AssertionError: expected [true] but found [false]
Expected :true
Actual   :false
