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. | ||
