I found this statement is some old code and it took me a second to figure out...
IsTestActive = (TestStateID == 1 ? true : false);
Please correct me if I'm wrong but isn't this the same as this one?:
IsTestActive = (TestStateID == 1);
If it is, why would you ever want to use the first? Which one is more readable? (I think the latter, but I'd like to see what others think.)

Boolean values and operationsConstant true is 1 and constant false is 0. It is considered good practice, though, to write true and false in your program for boolean values rather than 1 and 0.
There are only two boolean values. They are True and False . Capitalization is important, since true and false are not boolean values (remember Python is case sensitive).
Boolean Variables and Data Type ( or lack thereof in C )Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true.
There are three distinct numeric types: integers, floating point numbers, and complex numbers. In addition, Booleans are a subtype of integers.
Yes, it is exactly the same.
Yes, the latter is more readable.

IsTestActive = (TestStateID == 1);
is definitely more readable.
You could make a case for defining a constant
ACTIVE = 1
then replacing the boolean variable IsTestActive with
(TestStateID == ACTIVE)
The way the code is now, the state of the boolean IsTestActive will be erroneous if the state of TestStateID changes without updating the boolean. Bypassing the boolean and testing the real source of the information you're after will remove the possibility of this error.
