How can I verify that one of two methods was called using Mockito?

Question

Suppose I have a class with two methods where I don\'t care which is called...

public class Foo {
    public String getProperty(String key) {
        return

You could use atLeast(0) in combination with ArgumentCaptor:

ArgumentCaptor propertyKeyCaptor = ArgumentCaptor.forClass(String.class);
Mockito.verify(foo, atLeast(0)).getProperty(propertyKeyCaptor.capture(), anyString());

ArgumentCaptor propertyKeyCaptor2 = ArgumentCaptor.forClass(String.class);
Mockito.verify(foo, atLeast(0)).getProperty(propertyKeyCaptor2.capture());

List propertyKeyValues = propertyKeyCaptor.getAllValues();
List propertyKeyValues2 = propertyKeyCaptor2.getAllValues();

assertTrue(!propertyKeyValues.isEmpty() || !propertyKeyValues2.isEmpty()); //JUnit assert -- modify for whatever testing framework you're using
