In addition to user-defined JavaScript commands introduced through user-extensions.js, the Selenium IDE allows the user to create JavaScript queries or functions directly in the Target field. For example, let's run a Google search by getting a random number between 1 and 100, as follows:
The following HTML source tags let you convert the steps into runnable test scripts:
<tr>
<td>store</td>
<td>javascript{'Random number ' + Math.floor(Math.random() * 100);} </td>
<td>search</td>
</tr>
<tr>
<td>echo</td>
<td>${search}</td>
<td></td>
</tr>
<tr>
<td>open</td>
<td>/</td>
<td></td>
</tr>
<tr>
<td>type</td>
<td>id=gbqfq</td>
<td>${search}</td>
</tr>The predefined Selenium IDE JavaScript command runScript is a very powerful command that lets the user execute simple JavaScript functions directly from the IDE, for example, javascript{alert("Hello!")}.
Let's see how we can disable an active textbox and enable an inactive textbox using the following code snippet:
document.getElementsByName('****')[0].setAttribute('disabled', '')
document.getElementsByName('****')[0].removeAttribute('disabled');
The scroll event is currently unavailable in the Selenium IDE. However, the user-extensions.js file includes a JavaScript method that lets you scroll the mouse through the web page.
Refer to the Google site https://sites.google.com/site/seleniumworks/selenium-ide-tricks to download user-extensions.js. This user extension file includes IDE commands like while, endWhile, gotoIf, gotoLabel, and push. Increase the value to 10 based upon the vertical length of the web page, as shown in the following screenshot:
The Selenium IDE command storeEval is used to store values in a variable while running scripts, whereas storedVars is a JavaScript associate array with string indexes containing variables. In the following example, storeEval reserves the list of rivers in an array, and
getEval is a command for initiating and incrementing the values. Some of the commands used in this section are purely user-defined, such as while, endWhile, and so on. Here, the endWhile command is used to break the loop once the value inside the array reaches the maximum limit. The following screenshot gives us a clear idea of what is being discussed here:
Let's see another example of advanced parameterization concepts using the Selenium IDE. Refer to the Google site https://sites.google.com/site/seleniumworks/selenium-ide-tricks to download the user-extensions.js file. The following screenshot captures the essence of this discussion:
In this example, the values are pushed into the array manually, and it does a Google search one by one.
