I started writing about Page Objects earlier this month, and as soon as you start talking about Page Objects, you need to have an opinion about where to put your assertions. Do you ask the page if it is in the state it expects to be or do you ask the page for values and assert that they are what you expect them to be in the test?
If you look at FluentLenium and Simplelenium on GitHub, you’ll notice that their corresponding
READMEs describe the usage of the Page Object pattern. Now, if you take a closer look, you’ll also notice that they have an opinion: they’ve included the assertions in the definition of such Page Objects.
Now, my first experience with Page Objects was actually under these conditions. The Page Objects were the main driver…

If you’ve written acceptance tests for web applications in the past (also called feature tests), you might be familiar with tools like Capybara, Simplelenium and FluentLenium. These are great abstractions over the browser (thanks, Selenium!) that provide very nice APIs for testing web applications.
If you’ve done this for a while, you might also have heard of Page Objects. The idea behind them is that your tests should be about the behavior of your application and not about the underlying HTML, since the HTML is an implementation detail and probably not the interesting part of your tests.
Our base acceptance test
Let’s assume that we are working on an application where you can browse and review restaurants and we have an acceptance test…

If you’ve worked with relational databases and any ORMs like Java’s Hibernate, .NET’s NHibernate or Rails’
ActiveRecordin the past, you might be familiar with SELECT N+1 issues. It is a common performance problem in database-dependent applications and, because of this, these ORMs provide a built-in solution to this problem.
eager_loadcome to the rescue. Therefore, it is not unusual to find these keywords scattered in different places where your application accesses the database. Hopefully this isn’t a lot of places though - you are using Query Objects, right?
An example application
Let’s imagine for a second that we have an application where you can browse restaurants, which in turn have many reviews…

If you have worked with Ruby on Rails before then you might be familiar with ActiveRecord
scopes. Using them, you can achieve what many would consider very readable code. Let’s say that we have an application where we display an inbox where users receive messages.
class Message < ActiveRecord::Base end
Now, let’s imagine that after reading a
Message, it is marked as read, and let’s represent that with a
readcolumn in the database. Additionally, our users can either archive the
Messageor move it to the trash. We’ll represent this concept with a
locationcolumn in the
Querying the database the Rails way
Let’s say that our users want to have a way to view unread messages in their inbox. Using
ActiveRecord, you could achieve…

I am proud to announce that version 0.1.2 of the jQuery Rambling Slider has been released!
It really has been out for a couple of days now, but I’ve had a couple of busy weeks. Nevertheless, I managed to do the major refactoring that I mentioned when version 0.1.1 was released. So, what have I added to this new release? Here’s the list:
- Added the ability to call the

- Refactored the build process, as the commands remain the same (
- Added the missing yuicompressor (oops…)
- Reformatted the for loops to be more CoffeeScript-ish.
- Added the…
