Top 3 UFT API WSDL issues
Here are the three most common issues you may encounter when importing WSDLs in UFT API
- You can’t even import the WSDL in UFT
- You can import the WSDL, but get funky issues when trying to drag its methods on the canvas area
- Everything works fine until your run it and get “Structural Validation fails” errors
UFT unable to import your WSDL
Sometimes there may be a real issue with the WSDL you are trying to work with. The first thing I always do, before working with a WSDL, is try opening it up in a browser. If you can’t even do that, then it is a WSDL issue not a UFT issue. Also Yaron Navesh gave a great tip in this post comments section: “What I’ve seen many times is that people save locally or send in email a WSDL file without noticing that the WSDL references other WSDL/Schema files (“import” or “include” tags). It is always recommended to consume the WSDL from a live system (in any environment) but otherwise it is important to copy all dependent files and edit the WSDL (and files) to resolve references.“
If it opens in a browser, but not in UFT, the next step to try is to enable the Fuzzy feature in UFT. To use the Fuzzy option:
- Navigate to your HP\Unified Functional Testing\addins\ServiceTest\WSImportTechnology directory:
- Open up the WSImportTechnology.addin file (You may want to make a backup of this file before modifying it)
- You need to add the following importGeneralProperties = “[useFuzzy,true]” to these nodes:
<TechnologyImporter id=”HP.ST.WEBSERVISES” …
<TechnologyImporter id=”HP.ST.WEBSERVISESFROMURL” …
<TechnologyImporter id=”HP.ST.WEBSERVISESUPDATE” …
- Save the modified WSImportTechnology.addin file
- Restart UFT and try to import the problematic WSDL back into your UFT API test
The Fuzzy feature option will try to resolve any issues when UFT tries to compile the WSDL. Fuzzy knows how to fix common errors listed in its defined list. If the WSDL still cannot be imported you can open a ticket with HP, as they might be able to add the error to the Fuzzy list.
Issues when trying to drag your WSDL’s methods on the canvas area
This one is usually caused by older buggy versions of UFT or Service Test so make sure you are always using the latest patches. You will be surprised at how much grief you can save yourself by keeping up on the regular UFT patch releases. Be sure to check out my blog often for the latest HP patch releases.
Structural Validation fails
This message can be annoying and usually this simple fix gets rid of any “Structural Validation fails” errors when you try running your API script.
Under the WSDL operations that you are using on the canvas area go to each one’s Properties and uncheck the Validate structure checkbox option:
Running your test without this option will often times resolve the runtime validation errors.
