From what I read on "Issue 53" of mockito (https://code.google.com/p/mockito/issues/detail?id=53) , my code was experiencing a problem due to the validation framework involved in Mockito. Precisely the following code was causing the exception per se.
private ConstantNode getConstantNode(NumericalValue value){
ConstantNode node = Mockito.mock(ConstantNode.class);
Mockito.when(node.evaluate()).thenReturn(value);
Mockito.when(node.toString()).thenReturn(value.toString());
return node;
}
If you remember from my code, the parameter value is ALSO A MOCK, so that when value.toString()
is called on the thenReturn()
, I believe (and someone please correct me if I am wrong) that the validation framework is triggered and makes sure that every "when" has had its thenReturn()
called/validated/etc. So that if this happenes, the Mockito.when(node.toString()).thenReturn(value.toString()
will not be validated because it hasn´t returned from the valute.toString()
, which started the whole "validate everything" chain.
How I fixed it:
private ConstantNode getConstantNode(NumericalValue value){
ConstantNode node = Mockito.mock(ConstantNode.class);
Mockito.when(node.evaluate()).thenReturn(value);
String numberToString = value.toString();
Mockito.when(node.toString()).thenReturn(numberToString);
return node;
}
This way, it can be validated. I find this a complete code smell because I will literally have to leave a comment that explains why I am using a seemingly useless intermediate variable in the code.
Thanks for the help.

In today’s fast-paced world, the primary goal of every business is to release their application or websites to the end users as early as possible. As a result, businesses constantly search for ways to test, measure, and improve their products.

However, one of the possible challenges many business teams face is the release cycle time, which usually gets extended for several reasons.
So you are at the beginning of 2020 and probably have committed a new year resolution as a tester to take a leap from Manual Testing To Automation . However, to automate your test scripts you need to get your hands dirty on a programming language and that is where you are stuck! Or you are already proficient in automation testing through a single programming language and are thinking about venturing into new programming languages for automation testing, along with their respective frameworks. You are bound to be confused about picking your next milestone. After all, there are numerous programming languages to choose from.
There are times when developers get stuck with a problem that has to do with version changes. Trying to run the code or test without upgrading the package can result in unexpected errors.
