2 2 # A TestRequest is a composition of submission with user's testdata.
3 3 #
4 4 # Note about TestRequest#problem: Usually, A TestRequest has to be
5 5 # associated with a problem, so that execution environment can be
6 6 # determined. However, to be more flexible, we have to ensure that
7 7 # it works as well with problem=nil. In this case, we shall provide
8 8 # a "default" execution environment for it. This can be done
9 9 # seamlessly by using TestRequest#problem_name or
10 10 # TestRequest#name_of(problem) when retrieving the name of the
11 11 # problem: #name_of would return problem.name when problem!=nil and
12 12 # it would return "default" when problem=nil, #problem_name just
13 13 # call #name_of.
