What is the difference between assertEquals and assertSame?

assertEquals uses equals() method (that you should override in your class to really compare its instances) to compare objects, while assertSame uses == operator to compare them. So the difference is exactly the same as between == (compare by value) and equals (compare identity).

Does assertEquals use equal?

Yes, it calls equals and there is a separate method, assertSame , that uses == . Just to clear things up, assertEquals works with any object since all objects declare equals . Yes it does.

How do you use assertEquals in Python?

This function will take three parameters as input and return a boolean value depending upon the assert condition. If both input values are equal assertEqual() will return true else return false.

Does assertEquals check reference?

Checks the object reference using the == operator. If primitive values are passed and then the values are compared. If objects are passed, then the equals() method is invoked.

What is assertThat in JUnit?
