Question

Is there a way for js code to force Selenium testing to fail? For (a probably bad) example, if I had the following:

return document.getElementById('foo').innerHTML == 'hello'

is there a way I could make the ‘runScript’ command fail depending on if the js code returned true or false? (I know that example could be used by other Selenium commands, but I wanted a more general solution.)

Do I need to learn how to extend Selenium to add another command?

I’m also relatively new to Selenium so is this something that using Selenium-rc will solve?

Answer 1

assertExpression will give you what you’re asking for.

For instance, the following line would cause your test to fail if the JavaScript expression you mention did not evaluate to true.

<tr>
<td>assertExpression</td>
<td>javascript{this.browserbot.getCurrentWindow().document.getElementById('foo').innerHTML == 'hello'}</td>
<td>true</td>
</tr>
