How To Mock Method Of A Class Under Test With MOQ

Sep 15, 2011

I have a service class that i want to unit test. The service calls a repository class method in order to save some data. But before I call the save method, I have a validate method that belongs to the service class under test which validates the properies of the class to be persisted as a parameter to the repository save method.I know that to verify that the repository save method is called, i have to mock the repository class and set up the save method, but how do i verify that the validate method belonging to the service class under test is called when unit testing the method under test since they belong to the same class?

Partial Mock Of A Class With Private Constructor

Sep 9, 2011

I am trying to write some unit tests on a class that looks like this, using Moq [code] the parameterized constructor is private or internal one of the two methods relies on the result of the other.I want to check that when GetThisOrThat is called with a value, it actually calls GetThis. But I also want to mock GetThis so that it returns a specific well-known value.To me this is an example of Partial Mocking, where we create a Mock based on a class, passing the parameters for the constructor. The problem here is that there is no public constructor, and therefore, Moq can not call it..I tried using the Accessors generated by Visual Studio for MSTest, and use those accessors for the mocking, and this is what I came up with [code]

C# - Test For A Renamed Partial Method?

Jun 30, 2011

I'm using Linq to SQL, which generates partial classes and partial methods. You then extend that generated code by implementing your your customizations manually in another partial class. One of the hooks L2S gives you is the ability to implement partial methods that get called when a property changes. For example, if you have a property named "MyProp", then you can implement a partial method like so:

Use The Webrequest Webresponse Method To Test For The Existence Of A File?

Apr 2, 2010

I'd like to use the webrequest webresponse method to test for the existence of a file.If the first file is there, then I want to test for the existance of the same filename with -1.htm appended to it. If that filename exists, then test for filname-2.htm This continues until the filename being tested comes back 404 error. At which point, the program does NOT blow up, but the do until loop stops and the code continues. I have to search for a link on each one of the pages found once I have determined how many pages there are.How do I test for a file and not have it blow up? It has to loop and it goes through at least once. this is code I wrote. Right now the page just keeps going and going. IE's little logo on the page tab keep going around in a circle like it's in an endless loop.

Dim fr As System.Net.HttpWebRequest
Dim A As Integer = 1
Dim Count As Integer = 0

Create A New Class That Inherits From The Base Form Class And Define A New() Method With Parameters?

Oct 1, 2008

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

Call Method Base Class In Program Passing Sub Class Objects?

Apr 22, 2012

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

.net - Suppress A Property Or Method From A Base-class In A Derived Class?

Supose a base class

Public Class airplane

Private var_num_engines As Integer

Obviously, I don't wish that the class Glider has the method "start_engines" neither the property "num_engines". Otherwise, other child classes may have. How can I supress these property and method in child class, not just ignoring (if I can)?

Hiding A Method From A VB Class In A Derived C# Class?

Apr 20, 2011

I'm writing a set of unit tests for a large, complex class called ImageEditor from a piece of legacy code, where image processing and GUI functionality isn't strictly divided. One of the methods in the class, BaseImageChanged, seems to be concerned entirely with how images get displayed and should be disabled in my unit tests to avoid unnecessary complexity. The test project is in C#, and the original code is in VB; my idea was to create a Decorator for the class in C# and then hide the method behind an empty one that does nothing. However, when I try running the unit test, the VB code keeps referencing the old BaseImageChanged method as though the replacement didn't exist. Here's what I'm doing:

(VB class)
Public Class ImageEditor

Use Reflection To Unit-test An Internal Class Within An Assembly When The InternalsVisibleToAttribute Is Not An Option?

Aug 26, 2010

I have a solution with two projects within:

Company.Project.vbproj
Company.Project.Tests.vbproj

Within the Company.Project.vbproj assembly, I have a class FriendClass.vb which scope is Friend (internal in C#).Now I wish to test this FriendClass.vb from within the Company.Project.Tests.vbproj assembly. I know about the InternalsVisibleToAttribute, but that is not an option in Visual Basic .NET 2.0, as it is only available with C#, in .NET 2.0 (see here).I would like to create myself a proxy class using this internal FriendClass from within my testing assembly, so that I could instantiate it and do the testings accordingly.

Assign A Value To A Class From A Method Within The Class

Feb 13, 2012

I know this is possible, and it is probably something simple that I am missing... I have a fairly complex class to handle deserialization of an XML file. I wish to place a [class].loadfile method within the class. It looks something like this: Serialization decoration left out for simplicity...

[Code]...

The Deserialization is working just fine (that's my own code), but assigning the object value to Me is not correct. What I want is for an instantiation of this class to have a LoadFile method (similar to the XML class LoadFile method) - but I cannot figure out how to set the value of the class from within the class.

Creating A Mock Configuration Setup?

Nov 29, 2011

The program I am building requires a lot of initial user input. I was wanting to stream line this by creating a 'config' file so to speak that after the user enters all the initial data they can click a button that will save their entries into a secure file. When they leave for the day and come back they can click the load button and it auto fills in all the relevant data that will be stored in the file.

Still digging through the MSDN for help, but no luck on options yet.

I was thinking save the information to a text file somehow, but passwords will be stored and I would like to make it secure if possible.
