Recently I had to maintain a soap-based webservice. Really ugly stuff, you know. The problem is that I wanted to test my endpoint, but as the development environment is inside a docker that is inside a vagrant (is it correct to say this? 😩) I'm unable to use online tools like plum voice soap tester (or maybe it is some restriction in my network, not sure).

Looking for a desktop application I just found some specific to REST webservices. I didn't look much tought, I decided to try some way to test soap with a rest tool. And this is how I did it with Postman:

1. Set the request URL to use POST

For this tutorial we're going to use this wsdl: http://www.dneonline.com/calculator.asmx

1. Then, set the body to raw and the content-type to XML (text/xml)

2. Set the envelope according to the specifications

   <?xml version="1.0" encoding="utf-8"?>
   <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
    <Add xmlns="http://tempuri.org/">
      <intA>4</intA>
      <intB>2</intB>
    </Add>
   </soap:Body>
   </soap:Envelope>
   

3. Hit send! You should get the response below

   <?xml version="1.0" encoding="utf-8"?>
   <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <AddResponse xmlns="http://tempuri.org/">
            <AddResult>6</AddResult>
        </AddResponse>
    </soap:Body>
   </soap:Envelope>
