More new conventions for how I organize my tests!!
Written February 16, 2009 at 08:00 MST Tagged bdd and c sharp
As the current project I am on is getting fairly large now, I just recently switched around the way I organize my tests. Here is a sample concern pulled from a main class in my application (smart client based):
public class ApplicationControllerSpecs
{
public abstract class concern : observations_for_a_sut_with_a_contract<IApplicationController, ApplicationController>
{
protected IApplicationShellView shell_presenter;
}
[Concern(typeof (ApplicationController))]
public class when_starting_up : concern
{
context c = () =>
{
application_shell = the_dependency<IApplicationShellPresenter>();
start_all_modules = the_dependency<IStartAllModules>();
event_aggregator = the_dependency<IEventAggregator>();
};
because b = () =>
sut.start();
it should_start_the_application_shell = () =>
application_shell.received(x => x.start());
it should_start_all_of_the_application_modules = () =>
start_all_modules.received(x => x.run());
it should_register_itself_as_a_listener_with_the_event_aggregator = () =>
event_aggregator.received(x => x.register_listener(sut));
static IApplicationShellPresenter application_shell;
static IStartAllModules start_all_modules;
static IEventAggregator event_aggregator;
}
}
Notice how at the top I am now creating a container class which is named {SUT}specs:
public class ApplicationControllerSpecs
All of the concerns for the ApplicationController will be housed inside this class. From an organizational perspective I can now have a superclass for all of my concerns for a particular SUT named concern:
public abstract class concern : observations_for_a_sut_with_a_contract<IApplicationController, ApplicationController>
{
protected IApplicationShellView shell_presenter;
}
Before, I would place my concerns directly at the root of the file (not nested inside a container class), this meant that when I went to derive a concern from a base concern, I would have to filter through a big ReSharper list of all of the base test classes in the solution that started with the word concern. Because I was following a convention of “concern_for_[sut]”, I would see more than I wanted. Now when I am inside of a container class and am writing a concern that I want to derive from its parent concern,typing con followed by CTRL-SPACE will only give me a very small set of options. I also don’t need to come up with a fancy name for the initial concern superclass. I can just call it concern. Each *Specs file in my current application follows this convention, and each one has an initial superclass named concern. You don’t need the superclass, I just find it a convenient place to put fields etc that can often crowd up the test, common results etc.
