Cannot invoke isEqualTo(boolean) on the primitive type boolean

Question

This code needs to be tested but I'm not able to resolve the error. Boolean isValid is the method which needs to be tested.

 public boolean isValid(String email) 
    { 
        String emailRegex = "^[a-zA-Z0-9_+&*-]+(?:\\."+ 
                            "[a-zA-Z0-9_+&*-]+)*@" + 
                            "(?:[a-zA-Z0-9-]+\\.)+[a-z" + 
                            "A-Z]{2,7}$"; 
                              
        Pattern pat = Pattern.compile(emailRegex); 
        if (email == null) 
            return false; 
        return pat.matcher(email).matches(); 
    } 

Getting error in writing test case: Cannot invoke isEqualTo(boolean) on the primitive type boolean
@Test
    public void isValidTest() {
        Validation v = new Validation();
        String email = "bhavya@gmail.com";
        assertEquals(v.isValid(email).isEqualTo(true)); //this line gives the error.
    }

There are no methods for primitive types. Just use `assertTrue(v.isValid(email))`. — fuggerjaki61, Feb 04 '21 at 12:07

assertEquals(v.isValid(email).isEqualTo(true);

This line is wrong in so many ways.

The parentheses don't even line up.
The isEqualTo thing does not start with assertEquals - it starts with assertThat. You're mixing two completely different ways to write tests.
Because of the missing parens, you are now attempting to invoke .isEqualTo on a primitive boolean. It's not an object, primitiveExpression.anything doesn't work in java.

You presumably want either:

assertThat(v.isValid(email)).isEqualTo(true);

or more likely:

assertTrue(v.isValid(email));

assertThat code is also not working. AssertTrue worked. Thank you :) – Bhavya Feb 04 '21 at 12:21

`assertThat(v.isValid(email)).isTrue();` – Jesper Feb 04 '21 at 12:26

//you can try is it with assertTrue and pass the value type return by isValid()

@Test
public void isValidTest() {
   Validation v = new Validation();
   String email = "bhavya@gmail.com";
   Boolean value = v.isValid(email);
   assertTrue(value); 
}
