k0stya / Test doubles - dummy object.cs
Last active December 14, 2015 02:19
Dummy is a placeholder required to pass the unit test. Unit in the context (SUT) doesn't exercise this placeholder. Dummy can be something as simple as passing ‘null’ or a void implementation with exceptions to ensure it’s never leveraged.
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Moq;
namespace TestDoubles.Examples.Dummy
{
[TestClass]
public class Player_Test
{
[TestMethod]
public void Should_be_able_to_roll_die_wtih_max_face_value()

k0stya / Test Doubles - Stub.cs
Last active December 14, 2015 02:29
Stub replaces a real object and feeds the desired indirect inputs into the system under test.
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Moq;
namespace TestDoubles.Examples.Stub
{
[TestClass]
public class Player_Test
{
[TestMethod]
public void Should_be_able_to_roll_die_wtih_max_face_value()

k0stya / Test Doubles - Mock.cs
Last active December 14, 2015 02:38
Mock object replaces an object the system under test (SUT) depends on and verifies it is being used correctly by the SUT
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Moq;
namespace TestDoubles.Examples.Mock
{
[TestClass]
public class Player_Test
{
[TestMethod]
public void Should_be_able_to_roll_die_wtih_max_face_value()

k0stya / Test doubles - Fake.cs
Last active December 14, 2015 03:09
Replace a component that the system under test (SUT) depends on with a much lighter-weight implementation.
using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
namespace TestDoubles.Examples.Fake
{
[TestClass]
public class Invoice_Test

k0stya / Test doubles - Test-Specific Object - testing protected members.cs
Last active December 14, 2015 03:09
If the system under test (SUT) was not designed specifically to be testable, we may find that the test cannot get access to state that it must initialize or verify at some point in the test.
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Moq;
namespace TestDoubles.Examples.TestSpecificSubclass.ProtectedMember
{
[TestClass]
public class Player_Test
{
[TestMethod]
public void Should_be_able_to_roll_die_wtih_max_face_value()

k0stya / FalseWarning.cs
Last active December 14, 2015 08:48
Reshaper highlights n.Value saying that there is a possibility of InvalidOperationException.
using System.Linq;
namespace Nullable
{
public class Nullable_Test
{
public void SumNullableNumbers()
{
int?[] numbers = new int?[10];
int sum = numbers.Where(n => n.HasValue).Sum(n => n.Value);
