Flex 3.0 Installing and Configuring Flex Automated Testing

February 12th, 2009

To use Flex Automated Testing, you must install Flex Builder 3. You cannot use Flex Automated Testing with only the Flex 3 SDK.

Flex Automated Testing SWC files are installed by default with Flex Builder 3. They are located in the /frameworks/libs directory with the other SWC files. You can begin using Flex Automated Testing and build your own custom agents without any further installation.

To use run-time automated testing (recommended):

Open a command prompt.
Navigate to the flex_builder_root/sdks/3.0.0/templates/automation-runtimeloading-files directory.
Execute the build.bat file. This compiles the runtimeloading.mxml file into a SWF file.
Copy the runtimeloading. swf and RunTimeLoading.html file to your web server. Copy the Flex application that you want to test to this server as well (the application need not be compiled with automation libraries).
Request the RunTimeLoading.html file and pass your Flex application as the automationswfurl query string parameter; for example:
http://localhost/RunTimeLoading.html?automationswfurl=MyApp.swf
To compile your applications with static automation support:

Start Flex Builder.
Create a new Flex Project.
Select your new Flex project in the Navigator.
Select Project > Properties > Flex Compiler.
In the “Additional compiler arguments” field, enter the following:
-include-libraries “flex_builder_dir\sdks\3.0.0\frameworks\libs\automation.swc”
“flex_builder_dir\sdks\3.0.0\frameworks\libs\automation_agent.swc” “flex_builder_dir\sdks\3.0.0\frameworks\libs\qtp.swc”
“flex_builder_dir\sdks\3.0.0\frameworks\libs\automation_dmv.swc”
The -include-libraries compiler option is relative to the Flex Builder installation directory; the default on Windows is “C:\Program Files\Adobe\Flex Builder 3\”.

6. Click the OK button to save your changes and OK to close the project Properties dialog box.
7. Compile your Flex application.
Examples and documentation for using custom agents can be found at Custom Agents.

To use Flex Automated Testing with the Flex 3 Plug-in for Mercury QuickTest Pro, you must perform additional steps. The rest of this section describes how to install and use the Flex 3 Plug-in for Mercury QuickTest Pro.

[edit]Requirements for Using the QTP Plug-in
To test applications with Flex Automated Testing and the QTP agent, you must install the following:

Mercury QuickTest Professional 9.1 or later (no support for Smart Identification)
Mercury QuickTest Professional 9.2 and patch 1701 if you want Smart Identification support
Adobe Flex 3 Plug-in for Mercury QuickTest Pro
Microsoft Internet Explorer, version 6 or later
Flash Player ActiveX control, version 9.0.28.0 or higher
[edit]Installing the Plug-in
This section describes the steps necessary for a QC testing professional to configure QTP to work with Flex applications. You must install QTP and the plug-in.

To install QTP:

Install Flash Player 9 ActiveX control (9.0.28.0 or higher) for Microsoft Internet Explorer. This is currently the only supported browser/player.
Install QTP 9.1 or later if you do not require support for Smart Identification. If you want to use Smart Identification, install QTP 9.2 and patch 1701. You must get QTP 9.1 from Mercury.
If you are using Mercury QTP on Microsoft Windows Vista you need to turn off the User Account Control (UAC) feature. Instructions to turn off UAC are available here
Restart your computer.
To install the Flex 3 Plug-in for Mercury QuickTest Pro:

Run the flex_builder_root/Installers/QTP_Plugin_Installer.exe.
Start QTP.
Close QTP.
In addition to the plug-in’s DLLs and XML files, the plug-in installer includes the following in the installation directory:

/demo — Contains a Flash movie that describes the basics of using the plug-in. Be sure to enable audio on your computer.
/Uninstall Adobe Flex 3 Plug-in for Mercury QuickTest Pro — Contains the uninstaller.
[edit]Using the Plug-in
Start QTP again after installing the plug-in. The Add-in Manager lists the Flex plug-in.
Select the Flex plug-in in the Add-in Manager.
Select New > Test and click the Record button.
NOTE: Flex application testing with QTP currently supports only Microsoft Internet Explorer with the ActiveX Flash Player.

For more information on these tasks and using QTP to test Flex applications, see Testing with QTP.

For information on the operations and properties of Flex objects in QTP, see QTP Object Type Information.

[edit]Samples for Automated Testing
Sample custom agents are available at Custom Automation Agents.

An application ready for testing with QTP can be found at Flexstore AT. This sample can be used to test if the QTP plugin installation was successful.

An example for automating custom components can be found at Automating Custom Component.

[edit]Using automation with the Adobe Flex Component Kit for Flash CS3
You can create Flex controls, containers, skins, and other assets in Flash CS3 Professional, and then import those assets into your Flex application. When you want to automate an application that uses such assets, you must include the automation_flashflexkit.swc library.

If you are using run-time loading, re-compile the runtimeloading.swf file by using the build.bat file in flex_builder_root\sdks\3.0.0\templates\automation-runtimeloading-files\. The batch file includes the necessary libraries.

If you are compiling automation support into your application, add the automation_flashflexkit.swc to your include-libraries compiler option. This is in addition to the other automation SWC files. The SWC files are located in the flex_builder_root\sdks\3.0.0\frameworks\libs directory.

Flex overview

February 12th, 2009

Flex is a free, open source framework for building highly interactive, expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. It provides a modern, standards-based language and programming model that supports common design patterns. MXML, a declarative XML-based language, is used to describe UI layout and behaviors, and ActionScript3, a powerful object-oriented programming language, is used to create client logic. Flex also includes a rich component library with more than 100 proven, extensible UI components for creating rich Internet applications (RIAs), as well as an interactive Flex application debugger.

RIAs created with Flex can run in the browser using Adobe Flash Player software or on the desktop on Adobe AIR, the cross-operating system runtime. This enables Flex applications to run consistently across all major browsers and on the desktop. And using AIR, Flex applications can now access local data and system resources on the desktop. Both Flash Player and Adobe AIR are available as a free download on Adobe.com.

You can accelerate application development with Adobe Flex Builder 3 software, a highly productive, Eclipse based development environment, and Adobe Live Cycle Data Services software, a set of advanced data services that can be used in Flex development. Both of these products are available for purchase.

CSS Floats

November 18th, 2008

What Floats?

You can’t float every element on a Web page. To get technical, you can only float block-level elements. These are the elements that take up a block of space on the page, like images (), paragraphs (

), divisions (

), and lists (

    ). Other elements that affect text, but don’t create a box on the page are called inline elements and can’t be floated. These are elements like span (), line breaks (
    ), strong emphasis (), or italics ().

    Where Do They Float?

    You can float elements to the right or the left. Any element that follows the floated element will flow around the floated element on the other side.

    For example, if I float an image to the left, any text or other elements following it will flow around it to the right. See the example. And if I float an image to the right, any text or other elements following it will flow around it to the left. See the example. An image that is placed in a block of text without any float style applied to it will display as the browser is set to display images. This is usually with the first line of following text displayed at the bottom of the image. See the example.
    How Far Will They Float?

    An element that has been floated will move as far to the left or right of the container element as it can. This results in several different situations depending upon how your code is written. For these examples, I will be floating a small

    to the left:

    * If the floated element does not have a pre-defined width, it will take up as much horizontal space as required and available, regardless of the float. Note: some browsers attempt to place elements beside floated elements when the width isn’t defined - usually giving the non-floated element only a small amount of space. So you should always define a width on floated elements.
    * If the container element is the HTML , the floated div will sit on the left margin of the page.
    * If the container element is itself contained by something else, the floated div will sit on the left margin of the container.
    * You can nest floated elements, and that can result in the float ending up in a surprising place. For example, this float is a left floated div inside a right floated div.
    * Floated elements will sit next to each other if there is room in the container. For example, this container has 3 100px wide divs floated in a 400px wide container.

    You can even use floats to create a photo gallery layout. You put each thumbnail (it works best when they are all the same size) in a DIV with the caption and the float the divs in the container. No matter how wide the browser window is, the thumbnails will line up uniformly.
    Turning Off the Float

    Once you know how to get an element to float, it’s important to know how to turn off the float. You turn off the float with the CSS clear property. You can clear left floats, right floats or both:

    clear: left;
    clear: right;
    clear: both;

    Any element that you set the clear property for will appear below an element that is floated that direction. For example, in this example the first two paragraphs of text are not cleared, but the third is.

    Play with the clear value of different elements in your documents to get different layout effects. One of the most interesting floated layouts is a series of images down the right or left column next to paragraphs of text. Even if the text is not long enough to scroll past the image, you can use the clear on all the images to make sure that they appear in the column rather than next to the previous image.

    Images floated to the left and to the right.

    The HTML (repeat this paragraph):

    Mali with car Duis aute irure dolor sed do eiusmod tempor incididunt in reprehenderit in voluptate. Cupidatat non proident, ut labore et dolore magna aliqua.

    The CSS (to float the images to the left):

    img.float { float:left;clear:left; margin:5px;}

    And to the right:

    img.float { float:right;clear:right; margin:5px;}

    Using Floats for Layout

    Once you understand how the float property works, you can start using it to lay out your Web pages. These are the steps I take to create a floated Web page:

    * Design the layout (on paper or in a graphics tool or in my head).
    * Determine where the site divisions are going to be.
    * Determine the widths of the various containers and the elements within them.
    * Float everything. Even the outermost container element is floated to the left so that I know where it will be in relation to the browser view port.

    Starting to Position with CSS

    November 18th, 2008

    Once you have a series of

    tags in your HTML you can start positioning them on your page. There are many ways to do CSS positioning, but I find using float to be the easiest to manage and get my pages showing up how I want them to.

    1. Set a width on your body
    You don’t have to do this, but most pages are easier to read if you don’t assume that everyone will have their browser set to the same settings as your browser. I like to design for 1024×768 resolution, with a typical width of around 800px. However, I also have done fluid widths using percentages. It’s all up to you.

    2. Float everything
    Once you have your maximum width, then you can float everything on the page, and have it line up. For example, if you want your navigation

    to be at the top of the page, you would make it have a width of 100% and float left.

    But if you wanted it to be on the right side, you’d make it a width of less than 100% and float right.

    Then, anything that comes after it would be floated left, and as long as those elements had a smaller width than 600px (800 - 200), they would slide right in to the left of the navigation.

    3. Use floats to create margins
    One of the great things about floats is that you can use them to create margins without using CSS. For example, if my navigation is on the right and 200px wide and my body content is floated left and 580px wide, there will be a 20px margin between the two elements, without any margin tags at all.

    4. Get multiple columns by nesting

    elements
    If you want three columns, you create two divs that float left and right, and then in the wider div, you create a second set of two columns that float left and right inside it. HTML

    CSS (note that the inner divs have a width of 50% because they are half of the outer container, which is the “leftside” div:

    5. Test in multiple browsers
    While this technique works most of the time, some browsers react strangely to floats. You may have to play with the widths to get your elements to show up correctly.

    Grid Designs Don’t Have to Equal Boring

    November 18th, 2008

    The problem is, most beginning designers feel that designing on a grid is boring. And it definitely can be. This is especially true if you use the grid as a mandate to fill in every square of the grid with something. The point of a grid is not as a way to fill up space, but to help you organize the space you have.

    The trick to using grids in your layout is two-fold:

    * Create the grid, with as many sub-divisions as you need, and then stick with it. Don’t add random lines after you’ve created your grid. The benefit to a grid is the uniformity of it.
    * Place your elements on the grid lines, and make sure they fit the width and height of your grid lines. The most effective designs use the grid in balanced but not 100% symmetrical layouts.

    Once you understand how to set up your pages using a grid system, then you can start moving away from the rigid grids to create more elegant websites that work even if you can’t see the grid at first glance.

    Many Designs Use Grids

    November 18th, 2008

    Interior designers design rooms with grids. City planners design metropolitan areas on grids. And print designers design print layouts on grids. If you use a grid to design your Web page layout, you’ll create designs that look right and feel comfortable to most people.

    How can you fight spam on your blog?

    November 15th, 2008

    MT 3.3 offers a built-in spam protection plugin called SpamLookup. In addition to this plugin, there are several other options you can implement to help stem the tide of spam. Note that the spammers are constantly improving their methods to game the system, requiring constant vigilance on the part of the MT community to keep coming up with new ways to block them.

    * SpamLookup
    SpamLookup is a Movable Type plugin, developed by Brad Choate, that uses several techniques to identify spam, and then uses user-supplied choices to either moderate or block it. SpamLookup is an integrated part of MT 3.3, so if you have installed the latest version of MT, there is nothing more you need to install. SpamLookup utilizes several blacklist services to check incoming comments and trackbacks against known spammers. It allows you to either “junk” or moderate comments and trackbacks based on different settings for links and keywords. You can even “white list” domains or IP addresses. To adjust the settings on SpamLookup, simply open up your Plugins menu from the System Overview of your Movable Type editing window. Scroll to the bottom and select “Show Settings” from any of the SpamLookup modules. See Neil Turner’s suggestions on Making the Most of SpamLookup and David Philip’s SpamLookup’s Keyword Filter Explained for more information on how to best use this plugin.

    * Akismet
    Akismet is a distributed spam filtering service developed by the Wordpress community. According to the Akismet FAQ, the way it works is “When a new comment, trackback, or pingback comes to your blog it is submitted to the Akismet web service which runs hundreds of tests on the comment and returns a thumbs up or thumbs down.” MT developer Tim Appnel has created an MT plugin for Akismet (MT-Akismet) which can be downloaded from the Akismet website. Many have found Akismet to be more effective at catching spam than SpamLookup.

    * Comment Challenge
    Jay Allen’s Comment Challenge plugin requires a commenter to type a keyword into a separate field from the comment field in order for the comment cgi script to run. This plugin effectively halts automatic computer generated spam comments.

    * Use a “Captcha”
    A captcha is a security code that a commenter must enter in order for her comment to load. The benefit is that it screens out automated comment spam bots. The downside is that it keeps visually disabled people from easily contributing a comment. Arvind has released an SCode plugin to work with MT 3.2 - MT-SCode 1.0.

    * Require approval before a comment posts
    One way to ensure that your readers never have to see a spam message is that you personally approve comments before they are posted. MT3 has the comment moderation features built-in. (See Settings > Feedback > check “Immediate publish comments from No one”.)

    Close old comments.
    One way to cut down on blog spam is to reduce the opportunities by closing the ability to comment on blog posts older than X number of days. Mark Carey’s BlogJanitor plugin lets you do just that, and all automatically.
