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