Testing Soap/Rest Web Services with JMeter

  1. 1. Testing SOAP/REST Web Services Using JMeter July 2014
  2. 2. Representational Site Transfer (REST) • The most popular RESTs include: 1. GET 2. POST 3. PUT 4. DELETE • The response return status codes indicate success or failure, along with any applicable headers. JSON represents the affected fields (or nothing) in the message-body. * 02
  3. 3. How to Write a JMeter Script with GET (1) GET is the easiest and most common request method. To write a JMeter script with GET: 1.Add an HTTP Request to your Thread Group. 2.Fill in the Server Name or IP, path, and select the GET method. – For example, we use validate.jsontest.com as Server Name and ‘/’ as path 3.If your API request contains query parameters, you may specify them in [a] path (for example, ‘/?json=[1:1]’) or in [a] Parameters area: 1. Name: json 2. Value: [1:1] * 03
  4. 4. How to Write a JMeter Script with GET (2) 04
  5. 5. 4. Add the View Results Tree, and run the script. – Here you’ll find the sampler result, request, and response data of your request. * How to Write a JMeter Script with GET (3) 05
  6. 6. • With POST requests, you can fill both the body and the headers. You can also specify query parameters in path. • The HTTP headers, which contain metadata, are tightly defined by the HTTP spec. They can only contain plain text and must be formatted in a certain manner. * How to Write a JMeter Script with POST (1) 06
  7. 7. • To specify headers, you’ll need the HTTP Header Manager with the most common headers. These include Content-Type and Accept: – Content-Type : This entity-header field indicates the media type of the entity-body sent to the recipient. – Accept: This can be used to specify certain media types which are acceptable for the response. You can use a user agent to simulate different behaviors of various browsers. • Post Body can be useful for the following requests: GWT RPC HTTP, JSON REST HTTP, XML REST HTTP and SOAP HTTP. * How to Write a JMeter Script with POST (2) 07
  8. 8. For instance, when using the server name: www.webservicex.net Path: /periodictable.asmx Body: <?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> <GetAtoms xmlns="http://www.webserviceX.NET" /> </soap:Body> </soap:Envelope> And header: Content-Type: text/xml * How to Write a JMeter Script with POST (3) 08
  9. 9. * • You can configure other requests similar to GET and POST, using required methods, path, parameters, or body and headers. • Please note that the webservice (SOAP) request is depreciated and the SOAP/XML-RPC request is active. Please use the HTTP_Request instead. How to Write a JMeter Script with POST (4) 09
