    Hi all,

    the following piece of code returns different result on IE9 and FireFox14 browsers when attribute does not exist for specified element:
    HtmlControl control = Get(xpath, browser, errorMessage).As<HtmlControl>();
    string returnValue = control.GetValue<string>(attribute.ToString().ToLower());
    return returnValue;

    on IE9  returnValue is equal to '' (empty string)
    and on FireFox it is equal to 'null' (this is not NULL reference, this is a string 'null')

    This function has the following remark:
    Remarks:
    The property is retrieved by executing Javascript on the client side using the specified property name as the Javascript function.
    so I suppose it "forwards" the result from browser that executes Javascript.

    However, I expect methods to be browser-independent -> return the same result irrespectively of browser that is used.

    Can you please comment whether:
    1. I'm doing something wrong
    2. this should be treated as a defect that will be fixed some day
    3. this should be treated as a defect that will be never fixed
    4. this is a feature (please explain why)
  2.

    Hi Andrei,

    I am sorry to hear you are running into this problem. Unfortunately, the returned value is not "browser-independent". Test Studio simply takes the result from the JavaScript function and this result can be different in different browsers. We also have a section that gives some examples of Browser Inconsistencies. This article describes a similar problem with an HTML Button.

    If you are experiencing any difficulties with this behavior, please provide a sample site, a code block, and a deeper explanation of what you're trying to test and we'll try to find a workable solution for you.

    All the best,
