2 + # A TestRequest is a composition of submission with user's testdata.
3 + #
4 + # Note about TestRequest#problem: Usually, A TestRequest has to be
5 + # associated with a problem, so that execution environment can be
6 + # determined. However, to be more flexible, we have to ensure that
7 + # it works as well with problem=nil. In this case, we shall provide
8 + # a "default" execution environment for it. This can be done
9 + # seamlessly by using TestRequest#name_of when retrieving the name
10 + # of the problem: name_of would return problem.name when
11 + # problem!=nil and it would return "default" when problem=nil.
