Windmill Gets a Facelift for 1.0Beta1

Working up to the Windmill 1.0 Beta 1 Release, I finally had the opportunity to put some time into making the IDE (that a lot of you live in when in test writing mode) a little bit nicer to look at.

The IDE has been growing organically since 0.1 and there was a lot of functionality hacked into it that wasn’t in the original game plan, so I did what I could to improve the beauty of the CSS/Layout as well as the whole mess of code behind it.


Launching
If you have used our latest release, or are running trunk you know that we have significantly improved the load times for the Windmill IDE. By compressing the JavaScript when the service is instantiated we can simply hand the IDE window one file that contains the vast majority of the required code.

The reason that this makes such a huge performance difference is because we are loading the source via the local windmill proxy and the data size size had very little impact, the overhead was in the browser two connection limit. When you have to pull down ~30 files two at a time it takes its toll and made the IDE feel very sluggish and more like a web page loading than an IDE.

In the process of figuring out exactly what was slowing down the launch time we added some more informative messages and output so you don’t sit there staring at a twirling circle graphic wondering if anything is happening. And to make the experience even more fun, I couldn’t help but implement a progress bar.

General Layout
I removed the toolbar at the bottom of the screen, which I felt it was an irritation for test editing (especially with the drag and droppable actions). It is now in a drop down menu at the top right of the screen, with the rest of the UI access to IDE functions.

Settings and Firebug Lite Improvements
The settings dialog has continued to improve by implementing more useful defaults, adding new options, removing deprecated options and simply making it just look better. Thanks jQuery UI!

Firebug Lite has been a very popular feature since we first announced it, which has led to a handful of bug fixes over the last month. The most major of these was that the initial Windmill implementation of Firebug Lite required you to have Internet access as it was using resources that were hosted elsewhere.

These have since been copied to our source tree and are made available by the Windmill server so you can happily introspect your Web Apps JavaScript while writing tests on your Intranet.


Output and Performance
Instead of writing all the raw windmill output to the output and performance tabs there is now an array called windmill.errorArr, where all terrible errors and warnings about technical details are pushed in the case you are interested to see all that data. However, it’s more likely that you aren’t and scrolling through all that output data becomes tedious.

This is why we have implemented output in blocks with the background color representing pass/failure with green/red (white for performance). These blocks are expandable, clicking them will reveal all output (or performance information) we know about the action that was executed. This should give you a faster general overview of your results and allow you to quickly see the details you care about.


Other Worthwhile Mentions
We moved our XPath implementation from Ajax-Slt to JS-XPath, which has proven to be more accurate when it comes to resolving XPath generated in Firefox (or using Firebug) against non XPath native browsers such as IE.

Many bugs and improvements have been made to the DOM Explorer, which should now feel a lot more like the Firebug DOM inspector, but should work in any browser.

We have also put a lot of effort into improving the communication between the JavaScript Controller and the Python Service so that when a test fails you get as much detailed information in the service as you do in the IDE.

Timing and MozMill
The timing has lined up nicely as we are working on both a 1.0 release for Windmill and MozMill. MozMill is geared towards automated testing of all applications on the Mozilla Platform and functions in the trusted space providing lots of very useful flexibility.

You can currently try out MozMill 1.0rc1 as a Firefox Add-on, and keep your eyes pealed as some exciting new MozMill feature work is around the corner.

Participate
We are always trying to make life easier for the test writer, so please log your bugs and feel free to come chat with us in #windmill on FreeNode.

Bringing Windmill to Life

Windmill Logo

Project Status

I have spent nearly every day since July 7th working to bring the Windmill Project up to a level where it can be used reliably in a production environment. Our mission starts with “Windmill is a web testing framework intended for complete automation of user interface testing”, of course this refers to the web including everything and anything inside the browser window. This turns out to be a very large task, one that only an Open Source labor of love could possibly attempt to accomplish.

Windmill has slowly evolved as a project with user contributions, a moderately active IRC channel, and enough users to keep me from forgetting what a useful and powerful tool it is. When I was offered the opportunity to work on the project I quickly saw how much needed to be done in order to get to where we needed to be. We still aren’t quite there, and like most Open Source projects we might not ever get to the envisioned perfection, however recently we hit a very important milestone. The project is now fully hosted and run by the committers, and in many ways “Grown Up”, thanks to a lot of good advise and hard work. The milestone we have reached, is that Windmill is ready for YOU to use. This week we pushed 0.8.2, which is a release that has addressed all of the major issues that we know about and have discovered with heavy usage over the past months. Our hopes are that you will go install Windmill 0.8.2 and things will just WORK. If not, I can’t wait to get your issues in trac and see what we can do to fix them.

Priorities

The main things we care about when it comes to our web testing tools:

  • Low barrier to entry, low learning curve, and ease of use
  • Thorough documentation, community and project support
  • Support for the big 3 platforms; Windows, MacOSX and Linux
  • Support for the big 4 browsers; Firefox, IE, Safari and Opera
  • Easy integration with continuous integration tools
  • Reliability; developers aren’t going to pay attention if the failures aren’t real
  • A really nice looking logo, and a web site that is easy on the eyes..

There are always more features to implement, but Windmill hasn’t needed new features for a very long time. What Windmill needed was some serious QA, some code cleanup and a whole mess of bug fixes. If you look through the Trac Timeline you will see the massive amounts of all of the above that have happened and I am proud as hell when I launch the application today and see all that it can do.

What can Windmill do?

Windmill offers the ability to build, write, record and run tests as well as aid in debugging and development. In addition, the framework provides the ability to create and maintain hierarchies of smart and thorough tests that will ensure the quality of your web applications over time. Not only can we save you hours creating and maintaing tests, but we can also help you see your web application as a growing feature rich product, instead of a QA nightmare.

Many tools out there provide ways to write tests, some even provide recorders and DOM explorers, but none that I have ever seen provide this rich functionality cross platform and cross browser, which is really what is required in order to build a thorough test repository that represents all your possible users.

The current set of major features can be found at the Windmill Features Page as well as more details about what is currently available. One of the more exciting new features is the full integration with Firebug Lite. Web developers rely on the existence of Firebug in order to quickly build and debug web applications, and Firebug Lite is the next best thing. It’s hard to even describe how useful it has been to instantly access the JavaScript Console and DOM inspector in IE to debug a failing test. As the Open Source community grows, and tools are improved and brought to light, I think it’s very important to do everything we can to utilize these tools and use them to enhance the Windmill Framework.

Keeping it Open

The Open Source aspect of Windmill has turned out to be it’s greatest asset. The project is almost entirely written in JavaScript and Python, which instantly gives us many advantages over the competition. The JavaScript community is constantly evolving and is most certainly the futures technology platform. Python has a very strong community as well and has given us immense amounts of functionality and flexibility right out of the box.

One of the most exciting things to me personally about this particular project is the immense potential user base out there, and the large impact the Windmill Tools can have on the daily work flow of it’s users. Windmill was obviously inspired with the hopes of minimizing the need for manual testing of rich web applications, and has grown to be much more than that.

The future of the work to be done on Windmill will primarily be driven by the needs of it’s users, the changes and development of the industry and the success of it reaching the goal, to make web automation better.

Moving Forward

Concluding this major push of work, testing, documentation and moving of infrastructure; we now need to see how the community feels. There are lots of choices out there for web automation and we have made many differentiating choices along the way. It is now time to get the word out and take in some real feedback.

Thanks you all for input, contributions, patience and valuable feedback. Those of you who spent many hours on Freenode in #windmill with us debugging and hunting down those spastic blockers are troopers and we really appreciate it.

Mozilla Summit

I am currently up here in Whistler BC for the Mozilla Summit. There is about 400 people here staying at the Westin Resort & Spa up here in scenic Canada. 

The schedule for the con can be found here; http://wiki.mozilla.org/Summit2008/Sessions/Schedule

I do have to say that Mozilla is doing a great job at taking care of all their contributors and employees this week, and I feel like a lot of progress is being made on many levels. It’s very useful to see details as to how people are going about this, but it’s even more useful to see things on a bit higher level. It can be easy to get lost in the forest of Open Source, especially the way that Mozilla builds on things organically. 

The sessions are ranging from “The History of the Browser” to Mobile, QA, UE/UI, Thunderbird, planning etc. As Moz has people all over the world I am getting to hear some very interesting accents and interpretations of things. At the dinner last night I was sitting across from people from Germany, Macedonia and Israel. Amazing how the Moz projects can cross the globe and still keep communication open with each of it’s appendages. The keynote from Mitchell Baker and John Lilly gave me a very solid impression of what they feel the company values, where it should be going and most importantly their extreme satisfaction with where it currently is.

Tomorrow I will be doing a session with Mikeal Rogers and Clint Talbert to demo and explain the GristMill XUL testing framework. My piece of this project is called Mozmill, which started out as a straight across port of the Windmill source with the addition of XUL support and has turned into a much more advanced tool that will fill some needs that have existed for a very long time.

I found it interesting to find out that the VP of Engineering Mike Schroepfer announced his departure last week during Oscon. Their have been mixed reactions about this, but many speculations were proven correct today when he announced he was going to facebook, http://blog.mozilla.com/schrep/. The idea of an IPO is can be extremely appealing, apparently they made him an offer he couldn’t refuse.

This morning we were alerted that tons, literally tons of rock had fallen on the highway 99 which turns out is the most convenient of two possible road trips to get back to Vancouver. We are leaving Friday morning, and the new word is that we will all be loaded onto shuttles to embark on the 7 hour trip back to the airport. This will make for an extremely long day and I am not looking forward to it, but the trip was well worth it and I look forward to getting home and picking up where I left off at Slide.

OSCON 2008 Recap

This year was my second year at OSCON in Portland, and it’s pretty amazing for me to look back at last July and know that I was working at OSAF. A lot can happen in a year, but what didn’t surprise me was the amount of people that I interacted with at the con that I had met during my OSAF experience.

A few things come to mind when I think about the conference as a whole. First off, who gave OSCON a Ruby adrenaline shot? The Ruby track was pretty extensive, and I would say more prominent even than the Python track this year. I felt like many of the talks were very introductory with very few actual visual demo’s of things “working”. I know that OSCON brings a very diverse crowd.. but please, please come up with some way to show us if things are advanced, or not. I really get absolutely nothing out of introductory level JavaScript sessions, but a title like “Digging into the guts of JavaScript” could pretty much mean anything under the sun.

Some of the most interesting talks I attended last year had to do with open mapping and location services, I know you want us to also attend the “Where” conference, but these things are part of Open Source and should be represented at OSCON!

I really enjoyed the talk about CouchDB, I hadn’t heard about it and really enjoyed how it opened my mind up to some new concepts about how your application should interact with a database. I would advise everyone to check it out at http://incubator.apache.org/couchdb/.

Another was the “Django Tricks” talk, this was great because he just ran through a bunch of really cool examples — one of which was introspecting a sqlite db to build models from the schema. Pretty cool stuff! Additionally, I think Ted Leung nailed his talk about “Open Source Community Antipatterns”. A lot of the ideas and concepts weren’t new to me, but it always helps to get a more detailed overview from someone who has seen these patterns repeated over the last 10 years.

The best quote I heard was that the “Second OSCON starts at 6pm each night.” I completely agree with this, the social aspect of the conference is invaluable, but be careful about all those free booze — they sneak up on you if you aren’t careful.

I do feel as if I should have done a Windmill talk this year, I didn’t see anything from Selenium or Watir and if we had been a little farther a long with the next iteration on Windmill it would have been a great venue to get some serious exposure. I may attend some other conferences this year, or wait till OSCON next year for Windmill to make it’s big splash.

Leaving Rearden Commerce, What’s Next?


What happened?

As some of you may have heard, today I resigned from my position at Rearden Commerce. Leaving a company is never a fun thing, because you know how you feel when you hear that someone else is leaving.. and you can see it in people’s eyes. I have reminded myself multiple times today that I am still going to be 30 mins away, most of my communication with those people has been via email and IM and there is no reason for me not to stay in touch.

Why did I resign?

That’s a very good question. Let me preface this by saying that I really don’t have anything about Rearden that I can point at and say ‘this thing’ is why I left. Rearden is a great company, they were professional through out my entire experience there. They employ many very talented and driven engineers, and they have a great product. My gut feeling after spending some time there, is that they will do very well. The management team is very skilled and they know their market and niche extremely well. Every day I went to work I heard about a new major deal or a small company Rearden had acquired to contribute to their march toward owning the ‘Personal Assistant’ space.

When I first arrived there I struggled with two things, and ultimately wound up being my demise as an employee. I have an extreme passion for Open Source, being part of that community, and giving my time to contribute. So you are probably thinking, ‘Why didn’t I just do that on the side?’ — well the answer is that I did do it on the side and the results were slow and my sleep schedule paid the price. Rearden has a very business/enterprise specific niche at the moment, and building and deploying new features to those customers is a priority (as it should be), but I couldn’t stop my Open Source envy. 

Secondly, a overwhelming majority of their user base is using IE6. As a web developer — the last thing I do when building anything in client side JavaScript is to test it in IE6. I basically hold my nose, load the page and pray that things ‘mostly work’. Now I’m not going to claim that I can ever get away from doing this, but building really cutting edge features based on new technology becomes significantly less probable when you are catering to this crowd. I know that Rearden has some really cool future plans, and is publicly talking about bringing the application to the consumer market — but I’m impatient and I just simply didn’t want to wait.


What’s Next?

I am going to jump right into a gig with Slide Inc. as a Web Developer. However, before I get to any Web Development tasks I am going to be addressing a pretty serious need they have in their QA department. Slide currently has many applications that are used directly on their site, slide.com and on social networks (primarily facebook.com and myspace.com) and right now they have essentially no functional automation.

At OSAF I saw what a major difference automated testing can make, and the reason I am so excited about this is because I was a QA Engineer at one point manually testing a pretty complex web application (Cosmo) and I have seen how much a difference test automation can make in the release cycle, the development cycle, QA test cycles and simply the daily lives of your poor QA teams.


How am I going to accomplish this task you might ask? Thats the best part — I have fixed about 10 bugs in Windmill in the last week, and will be putting whatever effort is required into getting Windmill to a state where we can functionally automate all of Slides application testing. This looks to be a serious win for Slide, and a serious win for Windmill. 

At some point in the future, when I feel that this project is to the point where it can be maintained and built on by the Slide QA teams I will move on to Web Development tasks. At that point a smaller amount of time will still be allocated to maintaining Windmill, adding new features that Slide and the community need and working towards the next evolution of Windmill. That is quite a ways off in the future, so I will address all that when the time comes.

The rest of my ‘free’ development time, will be consumed by a project that I am involved in with the Mozilla Corporation. This project lives in the QA realm as well, and could probably be classified as a distant cousin to Windmill. More details about that will be announced the week of OSCON, so keep your eyes pealed.

Change can be extremely tough, but it is also very exciting. I want to thank all of my former peers at Rearden for a good experience, and I wish them all the absolute best.

IE Web Development Tips

As a web developer you are probably aware of that sinking feeling in the pit of your stomach that you suffer when posed with the idea of testing your freshly written JavaScript that works perfectly in FireFox.

For years now, we have had to ‘suck it up’, and pour a glass of scotch to get through an afternoon of testing in IE. As I am now a Web Developer at Rearden Commerce who currently caters to an audience of enterprise users instead of your standard bay area geek population — I have to make sure everything I commit works nicely in IE.

Last week after a few hours of IE testing, and dirtying my code I worked so hard to perfect and refine with alerts everywhere I decided that there HAD to be a better way to do this. I went ahead and spent many hours searching the web, installing everything I could find that promised to make IE development easier and happily I can say — it was a success.

First and foremost however, there are a few tips I can give you right off the top that will make your life easier. Before you take the plunge into line by line alerting, go through your code and do the following;

* Remove unnecessary commas in your data structures:

( FF ignores this one, but IE will give you an error that isn’t helpful )
ex.

var superNinjaObject = {
me: 'adam',
home: 'oakland',
};

* Don’t try to access characters in a string as if it was an array:

( Works in FF, but IE will simply give you undefined and not tell you a thing )
ex.

var myString = 'Welcome to the Jungle';
$('mynode').innerHTML += myString[14]; //Broken in IE
$('mynode').innerHTML += myString.charAt(14); //Compatible alternative

Now we can get to what you are really interested in, the new tools:

1. Internet Explorer Development Toolbar

Get It: Microsoft Downloads

This is Microsoft’s best stab at a firebug equivalent. This gives you all the flexibility you need to inspect the DOM tree, look at CSS, Scripts, Images, Network etc. To put it simply, it makes IE development something you can swallow. I can’t image going back to IE development without this. Unfortunately it is missing two things, the first is the absolutely necessary JavaScript shell. This can be solved by using the IE JS Bookmarklet that you can find at blog.monstuff.com. Add this to your favorites and then whenever you need a JS shell, pop this up and hack away ( I agree it would be nicer if it was built in ). The second is the ability to set breakpoints and step through your code debugging and introspecting objects and variables. I do have a solution for this, see new tool number

2. Visual Web Developer 2008 Express Edition

Get It: Microsoft Express

This is the solution to your break pointing, stepping, introspecting needs. The way you use it is a bit awkward, but it does complete the development experience. To use this you need to create an empty web project and then start debugging. This will launch IE and bring you to a blank server page off the local MS web server instance. At this point you can go ahead and plug in the URL of the app you are wanting to test. Additionally if you have set any ‘debugger;’ statements in your source it will pick that up and automatically ask you if you want to start debugging there, or continue on. When you stop the debugging session in VWD it will kill your browser, so beware if you have to navigate to some deep point in your app you are probably going to get frustrated if you write buggy code. :) At it’s 1.4 Gb space requirement it’s hardly a comparison with firebug — but it’s certainly a step up from alerts all day long.

3. Microsoft Script Editor

Get It: Jonathanboutelle.com

If you don’t already have it installed, a good midpoint between nothing and Visual Studio Express is the Microsoft Script Editor which comes with office 2003, heres a video on how to use it, Video. Thanks for the feedback blogosphere.

I hope this made your life at least a small amount easier, happy IE developing.
