Abstracting SomeOtherDependency so we can test the ReallyHardToTest constructor
// This is an example class illustrating some common patterns
// that negatively impact testability
//
// In this round, we are introducing an abstraction
// for SomeOtherDependency
public class ReallyHardToTest{
SomeModel model;
IPathWrapper pathWrapper;
public ReallyHardToTest(ISomeOtherDependency otherDependency, IPathWrapper pathWrapper){
this.pathWrapper = pathWrapper;
model = new SomeModel();
otherDependency.DoSomething();
}
public void SetFilename(string fileName){
model.Filename = pathWrapper.GetFileName(fileName);
}
}
public class SomeModel{
public string Filename{get;set;}
}
public interface ISomeOtherDependency{
void DoSomething();
}
public class SomeOtherDependency : ISomeOtherDependency {
public void DoSomething(){
// Just here for illustration
};
