Selenium: Get unique value?

Question

Just using selenium to fill out some forms for me. I need it to generate a unique value for my username field. How can I do that?

I've got

Command: type
Target: id_of_my_field
Value: username+unique_value ???

Answer 1

You can use javascript to do that:

Value: javascript{'username'+Math.floor(Math.random()*100000)}

This will append a 6 digit random number to your username.

See this SO question and answers for more details and other ways to do this...

Steps for a globally reusable solution is as follows

1) Download sideflow.js from Download here

2) Add following lines into it :

Selenium.prototype.doTypeRandomName = function(locator) {
    /**
     * Sets the value of an input field to a random email id,
     * as though you typed it in.
     *
     * @param locator an <a href="#locators">element locator</a>
     */

    // All locator-strategies are automatically handled by "findElement"
    var element = this.page().findElement(locator);

    /* The following block generates a random email string */
    var allowedChars = "abcdefghiklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890";
    var stringLength = 8;
    var randomstring = '';

    for (var i=0; i<stringLength; i++) {
        var rnum = Math.floor(Math.random() * allowedChars.length);
        randomstring += allowedChars.substring(rnum,rnum+1);
    }

    // Replace the element text with the new text
    this.browserbot.replaceText(element, randomstring);
};

3) Save the file

4) Go to Selenium ide -> options -> options ->Selenium Core extensions -> give reference of your file there.

5) Now your randomname function will appear in auto-intellisense and will be as "typerandomname" command category.

6) Sample usage could be (if base url is google.com)

<tr>
    <td>open</td>
    <td>/</td>
    <td></td>
</tr>
<tr>
    <td>typerandomname</td>
    <td>css=input[class='gbqfif']</td>
    <td></td>
</tr>

Hope this helps you

Answer 3

My solution which works well for me:

Save the following TEXT as a .js file and add to the Options->Options "Selenium Core Extensions" list...

Selenium.prototype.doTypeRandomName = function(locator) 
{
  /**
  * Sets the value of an input field to a random "name" 
  * as though you typed it in.
  */
  // All locator-strategies are automatically handled by "findElement"
  var element = this.page().findElement(locator);

  /* The following block generates a random name 8 characters in length */
  var allowedChars = "abcdefghiklmnopqrstuvwxyz";
  var stringLength = 8;
  var randomstring = '';

  for (var i=0; i<stringLength; i++) {
    var rnum = Math.floor(Math.random() * allowedChars.length);
    randomstring += allowedChars.substring(rnum,rnum+1);
  }

  // Replace the element text with the new text
  this.browserbot.replaceText(element, randomstring);
}

Once done, you can simply select the TypeRandomName command in Selenium for each text box where you want a random "name" to be generated.

Here is a way to generate unique numbers without using JavaScript in your code: (i used Java)

    DateFormat dateFormat = new SimpleDateFormat("ddHHmmss");            /* Here you create object of the class DateFormat, and SPECIFY THE FORMAT (ddHHmmss). (Don`enter code here`t forget to import class Date(ctrl+shift+o  if you are using Eclipse)) */  
    Date date = new Date();                                              /* Here you create object of the class Date. (Dont forget to import class Date. (Dont forget to import class Date(ctrl+shift+o  if you are using Eclipse)) */  
    String random_number = dateFormat.format(date);                      /* Assign your current Date(something like 19184123) (ddHHmmSS) to a local variable(it require a String) */  
    yourWebDriver().findElemnt(By.cssSelector("input#someId")).sendKeys("test"+random_number+"@tester.com");    /* send keys to your input injecting random number */ 

Such method will give truly unique number that will never repeat itself, because it use your current time...

You can add even further randomness if include mile seconds into DateFormat
