Our WebService has one of the parameters defined as data type - double.When calling WebService in TestComplete and passing in the values (e.g 0.01,0.002,0.0003) everything seems to work Ok.However, when value is passed into the parameter with 5 decimal points (e.g 0.00003)the TestComplete must be formatting it with mantisa as the exception is thrown by the WebService:The value '3E-5' cannot be parsed as the type 'decimal'.</faultstring><detail><ExceptionDetail xmlns="http://schemas.datacontract.org/2004/07....Is anyone aware of the configuration setting within TestComplete so that sending double(float) value in the scientific notation can be turned off?

Finally got the workaround from SmartBear:Hi,The problem with the web service method call in this case occurs because of difference between scripting and SOAP data types - there's no scripting analogue for the SOAP:Decimal type, and strings are used for data conversion.As a workaround, you can try using the following function to pass values in the target method. Parameters of these function are:Name: string - the parameter name as it is declared in the service.Namespace: string - the namespace where the method is defined.Value: the parameter value (e.g. 0.00003).Here's the function's code (JScript):function CreateParameterNode(Name, Namespace, Value){ var Document = Sys.OleObject("Msxml2.DOMDocument"); var Element = Document.createNode(1, "Name", "Namespace"); Element.appendChild(Document.createTextNode(0.00003)); return Element;}

Hi Djordje, I never met such a problem, but personally I would have try to double-check that web service under development reports correct problem and capture the request sent by TestComplete using Fiddler, WireShark or any other http-capturing tool. Wouldn't you mind to try to capture the problematic request (and the good one, to have something to compare with) and either post it here (along with the WSDL file of the tested web service) or open support ticket (http://support.smartbear.com/message/?prod=TestComplete) and provide Support with the same details?

Hi Alex,I spoke to the developers and asked them to execute the very same test case as a unit test in Visual Studio and WebService call was successful generating positive response. (I watched over their shoulder as they've executed a test).I have even hardcoded parameter values in a WebServices.ServiceName.Method(.....,0.00003,....) call and would still get an exception as above from the WebService.

This is all good, but nevertheless, personally I, would capture request sent to the wire by TestComplete. (As a tester you can never trust developers, especially in their environment... (to grin or not to grin is up to you ;) )

Hi Alex,unfortunately, the developer is right this time. I have recorded traffic using Fiddler and indeed the XML TestComplete is sending across to WebService is using scientifica notation format with mantissa such as:....><ns1:executionFee>3E-5</ns1:executionFee><......This must be down to the TestComplete converting floats with 5 decimals or more into the scientific notation format.

Hi Alex,

I have opened Support request but still didn't get resolution to the problem.

BTW, I am developing in JScript, as that's what the project is setup with.

Calling aqString.Format() in all 3 cases displays the value as expected: 0.00003. It's strange that in DelphiScript the 3rd case is not valid

However, when TC sends that value via param to the WebService seeing that it's a double data type it converts it using scientific notation number, which WebService doesn't like.

The data is read from the CSV file using DDT Value call and replaced with params to WS.

As previously stated, even when I hard code 0.00003 into a parameter to WS, it still gets rejected by the WS, as the TC sends it as 3E-5 number and not a decimal.

Hi Djordje,

I believe you'll get a response from Support on the created case soon and will appreciate if you let us know the final result here. I love web services testing functionality in TestComplete, like to test web services and had several interesting successful projects with them and this is the reason of why I am interested in this problem.

The only thought I have now, is do you know if there is some standard that specifies how doubles can be converted to strings? The idea is that if scientific notation is allowed for the string representation of double, then I would say that, generally speaking, TestComplete behaves correctly (though maybe in an unexpected manner) and the problem is with the web service been not able to convert double presented in one of the possible string forms into native binary representation.

Hi Djordje,

Thank you a lot for the update!

Not sure I completely understood Support's explanation... but this is out of scope.

Also, it is my understanding, that with the workaround suggested it is not possible to write test code as WebServices.ServiceName.Method(.....,0.00003,....) but you must create the OnWebServiceRequest handler and modify the request there (or create request manually), right?

Do you know if they are going to fix this problem in (the next) TestComplete update?
