Null Value testing
I have 3 input parameter in SOPA project. I want to test what happens when a null value is passed to one of the string.
Is there a way to pass a null string.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:lib="foo.com">
<soapenv:Header/>
<soapenv:Body>
<lib:foo>
<lib:fooA>?</lib:lib:fooA>
<lib:lib:fooB>?</lib:lib:fooB>
<!--Optional:-->
<lib:lib:fooC>If I leave it as empty it's going as string.Empty in the code. I want the value to be null.</lib:lib:fooC>
</lib:foo>
</soapenv:Body>
</soapenv:Envelope>
Tried below method - Did not work.
xsi:nil="true"
C#code behind:
[webmethod]
public bool foo(String a, String b, String c)
{
If( c == null)
I want this condition to be a success for the testing.
}
Thank you.
In this case you are actually asking a question about the C# side of your code, so I'm not sure you can get a definitive answer here. In XML, xsi:nil="true" does represent a NULL, but your C# library might be returning a different value. It may not be one of the potential results for your library at all, in which case you don't have a valid test case.
The things to test for from the client side is how your API will respond to each of ....
<lib:lib:fooC></lib:lib:fooC>
<lib:lib:fooC/>
<lib:lib:fooC xsi:nil="true"/>
Remember, your xml document must include the name space declaration:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"<!-- lib:lib:fooC/-->
(There may be no difference between the first two).
If all of these get the response you expect, and none of them trigger that branch in your C# code, then it probably is just dead code (code that will never be called) and probably should be removed.
