It is well -described <a - href="http://www.mozilla.org/projects/security/components/same-origin.html">here</a>, -but for our purposes, it constrains the way that a -JavaScript in a browser may interoperate with other open frames and -windows. In short, the Selenium JavaScript app must come from (or -appear to) the same origin as the AUT.<br> -<h2>The Driver</h2> -The driver has a number of duties. These are typically.. <br> -<ul> - <li>Instantiating the web server with a dynamic app (servlets for -Java) </li> - <li>Launching a browser with a with a URL that makes sense for -connecting to that server </li> - <li>providing an API to such that commands can be routed though the -dynamic app to the browser</li> -</ul> -<h2>Local, Remote and URLs<br> -</h2> -An application may be testable in a remote location by humans, but for -scripted testing and the need for the driver to dynamically drive the -browser, it is optimal for the driver to be on the same machine as that -serving the AUT and the browser testing it. <br> -<br> -Thus, an application as deployed ...<br> -<br> -<img alt="http://localhost:8080/" src="images/stockmeister.png" - style="width: 361px; height: 68px;"><br> -<br> -... would appear like so for the purposes of testing ...<br> -<br> -<img alt="http://localhost:8080/" src="images/localhostAut.png" - style="width: 346px; height: 43px;"><br> -<br> -As with the standalone version of Selenium, there are a number of files -(HTML and JavaScript) that comprise the bulk of the testing framework -and sit in the browser as testing occurs. It makes most sense to put -these in a virtual directory on the same server ...<br> -<br> -<img alt="http://localhost:8080/selenium/" - src="images/localhostSelenium.png" - style="width: 326px; height: 57px;"><br> -<br> -The dynamic webapp needs to be similarly mounted ...<br> -<br> -<img alt="http://localhost:8080/selenium/driver?..." - src="images/localhostDriver.png" style="width: 318px; height: 52px;"><br> -<br> -As the dynamic is the link between what is happening in the browser and -the driving process, it we need to somehow have an instance reference -to it. This is easier in some languages and web servers than -others. Also full programatic start/stop control over the web -server is not always possible for some larger web servers -implementations.<br> -<h2>Reply/Request Architecture</h2> -Because a browser cannot open a socket and listen on it, we must -effectively initiate communication thru the driver on the browser side. -Ignoring the possibilities granted by keep-alive, we simply poll from -the browser to the server and pick up commands to process inside the -browser. Results of commands are also passed back to the dynamic -hander over the same mechanism. These are in fact done in the same HTTP -request. The results from the <span style="font-style: italic;">previous</span> -command go back as query string parameters, and the <span - style="font-style: italic;">next</span> command is communicated in a -text/plain document<br> -<br> -The previous/next business introduces some complexity on the driver -side of the design. Namely hidden behind the API, the driver must -manage queues for the outgoing commands and the (some time later) -incoming responses. Java, until 1.5, did not have a blocking -queue to make this easy. Most other languages did.<br> -<h2><span style="font-weight: bold;">Selenese</span></h2> -<table style="width: 100%;" border="1" cellpadding="2" cellspacing="2"> - <tbody> - <tr> - <td>Selenese is the contrived (and mostly hidden) wire language -that the -driver uses to speak to the browser-bot through the dynamic -handler. It uses HTTP for its transport, and is quite -simple. <br> - <br> -Responses come from the browser to the driver in a query -string like <br> - <br> - <span style="font-family: monospace;">commandResult=OK</span>, <br> - <br> -Commands go from the driver to the -browser-bot in a text/plain document:<br> - <br> - <span style="font-family: monospace;">| open | /foo/bar.html | |</span><br - style="font-family: monospace;"> - <br> -This two way communication is of course invisible to the observer.</td> - <td style="width: 30%; background-color: rgb(255, 153, 102);">The -BrowserBot, by understanding Selenese, allows a process other than the -browser itsself to direct events on the Application Under Test. <br> - <br> -The Selenese language is simple enough to be commandable by any -language that has an API that can handle HTTP requests. <br> - <br> -Thus, Selenese allows many different open, free or closed license -drivers to interoperate with the BrowserBot.</td> - </tr> - </tbody> -</table> -<h2>Choregraphy</h2> -The driver cleary has some fairly heavy things to do. It is -important for some robustness to be built into the design. For example -it may take a long time for the browser to be instantiated on a -particular platform. It is appropriate for wait timeouts to be -generous here. Similarly whilst issuing individual commands it is -important for the driver to wait a sufficient amount of time for a -command to execute (and its result to come back). For the most -part on a localhost setup, it will be because the AUT is slow, but it -could be because some break in the app means that there will be no -subsequent response. Some timeout regime should be able to -recover from, mark a test as failed (for reasons of timeout), and start -again with the next test.<br> -<br> -<br> -</body> -</html> |
