Random checkout with 2 types of user using jmeter

Question

I am looking for random user type checkout for our ecommerce website with 2 types of users :

1. Guest User
2. Loggedin User [Already registered]

What my question is there will be diff. requests and POST parameters if I do checkout as guest and diff. parameters if I do checkout as loggedin user. So here how to handle it.

Random controller can be used but how can I tell jmeter that if random controller do checkout with guest then follow X number of requests in test plan otherwise follow Y number of requests for logged in user.

Answer 1

The easiest option would be using If Controller like:

• If Guest
  • HTTP Request relevant for the Guest User
• If Regiestered
  • HTTP Request relevant for Registered User

You can distinguish whether user is registered or not via i.e. Regular Expression Extractor

1. Add Regular Expression Extractor as a child of the previous request
2. Configure it to look for something which identifies logged in user and store the value into a JMeter Variable called foo

3. Use the following line in the If Controller condition area for the registered user

   "${foo}" != "null"
   

4. Use the following line in the If Controller condition area for the guest user

   "${foo}" == "null"
