Testing Soap interface with Robotframework Library

For efficient testing sometime you need to created automaticaly request xml feeding soap interface. If you are familiar with robot framework, it’s great. Robotframework has already 2 external Library, which handle SOAP interfaces communication.( Süds Library or Zeep Library ) .

There are a lot of opinion in Internet about these two libraries, discussing pro and contra using one of these lib. for testing SOAP.

Important things to do, you have to find out which library can handle “your WSDL“ better!

For my task, Suds library does.

How to find it out?

Just run your SOAP Library keyword pointing out your target WSDL .

Used “Create Soap Client” keyword for testing the binding if you get all the entities and objects on your WSDL, If the answed “OK” than you can used your Library for SOAP,


Ports (1):
….
Methods (10):
addToIndex(xs:string guid, )
getProductMetadaten(xs:string guid, )
getProductMetadatenGuidList(xs:string query, )
getProductMetadatenList()

Types (62):
ns3:AbstractCurveType
ns3:AbstractGMLType
ns3:AbstractGeometricAggregateType
ns3:AbstractGeometricPrimitiveType

If not you have to find out other library for interfacing with SOAP.

As sample I got these error using Zeep for parsing my WSDL:

self.item_type = self.item_type.resolve()
AttributeError: ‘lxml.etree.QName’ object has no attribute ‘resolve’

These error are related to these following open issue on Zeep:

Sample of created XML request from RF with Suds Library:


XML Request Created with RF & SUD from input WSDL

this is how I wrote it in Robotframework Test Suite:

map WSDL local
Run Keyword and Continue On Failure setProductMetadaten

this is how I wrote it in Robotframework Test Case:

show object setProductMetadaten
setProductMetadaten

calling internal keyword:

${object}= Create WSDL Object n2:ProductMetadata
Set Wsdl Object Attribut ${object.commonMetadata} identifier ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata} title ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata.description} summary ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata.description} comments ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata.product} type ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata.product} subtype ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata} rflAuftragsnummer ${dummy_text}
Set Wsdl Object Attribut ${object.commonMetadata.change} version ${dummy_text}
${result}= call Soap method setProductMetadaten ${object}

RFlog result

RFlog result

Creating 100X Request with RF For loop keyword

map WSDL local
:FOR ${i} IN RANGE 100
setProductMetadaten

Hope these infos help you starting your SOAP request creation with Robotframework & SudsLibrary, just another way of SOAP testing than using SOAPUI.
