| # 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 | ||||
|
jittat
|
r40 | # seamlessly by using TestRequest#problem_name or | ||
| # TestRequest#name_of(problem) when retrieving the name of the | ||||
| # problem: #name_of would return problem.name when problem!=nil and | ||||
| # it would return "default" when problem=nil, #problem_name just | ||||
| # call #name_of. | ||||
