Creating a high level test

Tests can be constructed either by extending from a base class (recommended for cleaner and more readable tests), or by using the test builder object.

Extending from BDTestBase

public class MyTests : BDTestBase
{
    [Test]
    public void Test1() {
        Given(() => Action1())
        .When(() => Action2())
        .Then(() => Action3())
        .BDTest();
    }
}

Or by using the BDTestBuilder object

public class MyTests 
{
    [Test]
    public void Test1() {
        new BDTestBuilder().Given(() => Action1())
                            .When(() => Action2())
                            .Then(() => Action3())
                            .BDTest();
    }
}

Best Practice

BDTest enforces best practice:

• Tests MUST contain

  • Given + When + Then and executed with a BDTest(Async)
  • OR
  • When + Then and executed with a BDTest(Async)

  The former would be when a test needs setup to get to the required state. The latter if no state is required.

• Tests MUST start with a Given or a When

  • Off of a Given you can have And or When
    • Off of an And you can have And or When
  • Off of a When you can have a Then
    • (No And - We should be testing one action!)
  • Off of a Then you can have And or BDTest(Async)
    • Off of an And you can have And or BDTest(Async)
