Does assertEquals(Object o1, Object o2) uses the equals method

Question

In other words, does assertEquals works with a class that overrides equals

Answer 1

From the source code of the assertEquals method that you can find on the Junit GitHub Repo:

/**  * Asserts that two objects are equal. If they are not  * an AssertionFailedError is thrown with the given message.  */ static public void assertEquals(String message, Object expected, Object actual) {     if (expected == null && actual == null) {         return;     }     if (expected != null && expected.equals(actual)) {         return;     }     failNotEquals(message, expected, actual); } 

You can see that Junit is using the .equals() method.

Edit:

The code snippet is coming from a deprecated version of Junit.

You can read about the source of the 'new' Junit here. The idea is pretty much the same, the .equals() method is also used.

does assertEquals works with a class that overrides equals?

Yes, assertEquals() invokes the overridden equals() if the class has one.
