In order to help my team write testable code, I came up with this simple list of best practices for making our C# code base more testable. (Some of the points refer to limitations of Rhino Mocks, a mocking framework for C#, but the rules may apply more generally as well.) Does anyone have any best practices that they follow? To maximize the testability of code, follow these rules: Write the test first, then the code. Reason: This ensures that you write testable code and that every line of code gets tests written for it. Design classes using dependency injection. Reason: You cannot mock or test

I am attempting to mock a call to an indexed property. I.e. I would like to moq the following: object result = myDictionaryCollection["SomeKeyValue"]; and also the setter value myDictionaryCollection["SomeKeyValue"] = myNewValue; I am doing this because I need to mock the functionality of a class my app uses. Does anyone know how to do this with MOQ? I've tried variations on the following: Dictionary<string, object> MyContainer = new Dictionary<string, object>(); mock.ExpectGet<object>( p => p[It.IsAny<string>()]).Returns(MyContainer[(string s)]); But that doesn't compile. Is what I am trying

I have written unit test for following action. [HttpPost] public ActionResult/*ViewResult*/ Create(MyViewModel vm) { if (ModelState.IsValid) { //Do something... return RedirectToAction("Index"); } return View(vm); } Test method can access Model properties, only when return type is ViewResult . In above code, I have used RedirectToAction so return type of this action can not be ViewResult . In such scenario how do you unit-test an action? So here is my little example: public ActionResult Index(int id) { if (1 != id) { return RedirectToAction("asd"); } return View(); } And the tests: [TestMethod

I've just begun learning about TDD , and I'm developing a program using a Tkinter GUI. The only problem is that once the .mainloop() method is called, the test suite hangs until the window is closed. Here is an example of my code: # server.py import Tkinter as tk class Server(tk.Tk): def __init__(self): tk.Tk.__init__(self) self.mainloop() # test.py import unittest import server class ServerTestCase(unittest.TestCase): def testClassSetup(self): server.Server() # and of course I can't call any server.whatever functions here if __name__ == '__main__': unittest.main() What is the appropriate way

When writing more than a trivial script in bash, I often wonder how to make the code testable. It is typically hard to write tests for bash code, due to the fact that it is low on functions that take a value and return a value, and high on functions that check and set some aspect in the environment, modify the file-system, invoke a program, etc. - functions that depend on the environment or have side effects. Thus the setup and test code become much more complicated than the code they test. For example, consider a simple function to test: function add_to_file() { local f=$1 cat >> $f sort -u
