c# - Providing a Generic to Mock -

i attempting generalize test code in solution mvc project. because we're writing same test each controller, thought use generics make 1 test needed.

unfortunately, i'm getting error: error 1 type 'trepo' must reference type in order use parameter 't' in generic type or method 'moq.mock<t>'

here's relevant code. can provide more if needed.

testbase.cs

public class testbase<tcontroller, tobject, trepo> tcontroller : irmccontroller<tobject> trepo : irmcrepository {     public mock<trepo> repo { get; set; } } 

companiestest.cs

public class companiestest : testbase<companiescontroller, company, icompanyrepository> 

thanks help.

in moq, mock<t> class has class constraint on generic type. here's how it's defined:

public class mock<t> : mock t : class 

so if intend use in class must define same class constraint in addition irmcrepository:

public class testbase<tcontroller, tobject, trepo>     tcontroller : irmccontroller<tobject>     trepo : class, irmcrepository  {     public mock<trepo> repo { get; set; } } 

now code's gonna compile. that's basic generic constraints in c#.
