Hello,

I am writing a assembly for Test Studio

I have tried to specify the base class that my class inherits as being BaseTest and BaseWebAiiTest

I have a Manager instance that is initialized to Manager.Current.

I can reference the myManager.ActiveBrowser... just fine.

But when I try to create a wait using:

HtmlInputCheckBox _checkbox = myManager.ActiveBrowser.Find.ByExpression<HtmlInputCheckBox>(DomString);

HtmlWait waitObj = _checkbox.Wait;

           
_checkbox.Wait.ForVisible(5000);

I get the following error when the coded step executes:

System.NullReferenceException: Object reference not set to an instance of an object.

The line that causes this exception is

HtmlWait waitObj = _checkbox.Wait;

I cannot find what object that needs to be referenced to instantiate this wait object.

Thanks

Hello Joe,

My #1 suspicion is that "myManager.ActiveBrowser.Find.ByExpression<HtmlInputCheckBox>(DomString);" did not actually find anything. When .Find does not find the target element what you get back is a NULL. The (rather obviously) "_checkbox.Wait;" will throw a null reference exception. You can verify the Find succeeded by testing for null like this:

Assert.IsNotNull(_checkbox);

The assert will fail and cause the test to abort of _checkbox is null i.e. the Find failed.

As a side note, given this code:
HtmlInputCheckBox _checkbox = myManager.ActiveBrowser.Find.ByExpression<HtmlInputCheckBox>(DomString);
HtmlWait waitObj = _checkbox.Wait;
_checkbox.Wait.ForVisible(5000);

The HtmlWait waitObj = _checkbox.Wait; code is unnecessary as you're not using waitObj later.
