What’s a good bit of JS or JQuery for horizontally scrolling news ticker

I am looking for a little bit of JQuery or JS that allows me to produce a horizontally scrolling “news ticker” list.

The produced HTML needs to be standards compliant as well.

I have tried liScroll but this has a habit of breaking (some content ends up on a second line at the start of the scroll), especially with longer lists.

I have also tried this News Ticker but when a DOCTYPE is included the scrolling will jolt rather than cycle smoothly at the end of each cycle.

Any suggestions are appreciated.

Edit

So thanks to Matt Hinze’s suggestion I realised I could do what I wanted to do with JQuery animate (I require continuous scrolling not discrete scrolling like the example). However, I quickly ran into similar problems to those I was having with liScroll and after all that realised a CSS issue (as always) was responsible.

Solution: liScroll – change the default ‘var stripWidth = 0’ to something like 100, to give a little space and avoid new line wrapping.

Answer

Smooth Div Scroll can also be used as a news ticker/stock ticker. It can pause on mouse over or mouse down and it can loop endlessly if you want it to.

Here’s the example with a running ticker.

Checking the results of a Factory in a unit test

I have developed some classes with similar behavior, they all implement the same interface. I implemented a factory that creates the appropriate object and returns the interface. I am writing a unit test for the factory. All you get back is an interface to the object. What is the best way to test that the factory has worked correctly?

I would like to know the answer in Java, but if there is a solution that crosses languages I would like to know it.

Number 2. in the answer, would be done like the other answer? If so I will mark the other answer accepted as well and reword my question to adress both a factory where an interface is returned and you have no clue what type of concrete class implemented the interface, and the case where you do know what concrete class was used.

Answer

Since I don’t know how your factory method looks like, all I can advise right now is to

  1. Check to see the object is the correct concrete implementation you were looking for:

    IMyInterface fromFactory = factory.create(...);  
    Assert.assertTrue(fromFactory instanceof MyInterfaceImpl1);
    
  2. You can check if the factory setup the concrete instances with valid instance variables.
