03 Testing

This module explores automated testing alternatives for your data models.

Notes: Uses NUnit, assumes you have a test runner available. There is an extension available for VS, also resharper supports NUnit out of the box.

Exercise Task 1 - Setup NUnit

1. Open the Todo project in Visual Studio from the Ex01 folder
2. Add a class library to the solution called Todo.Test
3. In the new library, add a nuget reference to NUnit
4. Add a reference to the Todo.Core project
5. Rename the Class1 to TodoTests and add TestFixture attribute.

Exercise Task 2 - Create a simple test

1. Create a test by adding the following method:

   [Test]
   public void Todo_Constructor_args_are_picked_up()
   {
       const int expectedId = 42;
       const string expectedTodo = "Give the dog a dose of meth";
   
       var todo = new Core.Todo(expectedId, expectedTodo);
       Assert.AreEqual(expectedId, todo.Id);
       Assert.AreEqual(expectedTodo, todo.Title);
   }

2. Execute the test

Exercise Task 3 - Write more tests

You're on your own now, create tests for the following:

1. That TodoModel.SetCategory(int,category) creates a category when missing

2. That SetCompletedCommand has the desired effect

3. Create a general smoke test which creates an engine, executes some commands and queries. Tip: You can create an engine for isolated test and in-memory storage using the following syntax:

   var config = new EngineConfiguration().ForIsolatedTest();
   var engine = Engine.LoadOrCreate<TodoModel>(config);
