Mockito verify message not accurate if type is fields are of Object

[LoganDev99]

Hi,

mockito: 5.10.0
jdk: Java 11
os: Windows 10

The mockito verify error message isn't accurate when the type of fields are Object and the object to match in mockito.verify() have a type mismatch. In my example I pass in a int 1 and a string 1. But the error message is wrong and only shows int 1 for both wanted and actual.

Run mvn clean test The test will failure. Which is correct. But the error message isn't correct.

Output:

Argument(s) are different! Wanted:
myService.myMethod(MyClass(myValue=1));
-> at com.example.mockitoissue.MyService.myMethod(MockitoissueApplicationTests.java:27)
Actual invocations have different arguments:
myService.myMethod(MyClass(myValue=1));
-> at com.example.mockitoissue.MockitoissueApplicationTests.contextLoads(MockitoissueApplicationTests.java:18)
Wanted should show a string value the number 1 for myValue=1. Instead both are shown as the same.

Clicking in accurately shows the difference being a new line.

Also snippet for searchability.

class MockitoissueApplicationTests {

	@Test
	void test() {
		MyService myService = mock(MyService.class);

		MyClass myClass1 = new MyClass(1);
		MyClass myClass2 = new MyClass("1");

		myService.myMethod(myClass1);
		verify(myService).myMethod(myClass2);
	}

}

class MyService {

	public void myMethod(MyClass myClass) {
		System.out.println(myClass);
	}
}

@Value
class MyClass {
	Object myValue;
}
