How to verify if values are updated or not by API using groovy in soap ui - groovy

Question

I am using soapui and groovy for api automation and assertion.
Have one API which updates user profile data. i.e update username,firstname,lastname etc.
What is best way to verify that if data is updated or not after run update api. In groovy is there any way by which I can store previous data from API response then run update api and again check response and finally compare previous response and latest one?
What I have tried it comparing values which I am going to sent via API and values which API returns. If both equal then assume that values update. But this seems not perfect way to check update function.

Answer 1

Define a test case level custom property, say DEPARTMENT_NAME and value as needed.
Add a Script Assertion for the same request test step with below script:
//Check if the response is received
assert context.response, 'Response is null or empty'
//Parse text to json
def json = new groovy.json.JsonSlurper().parseText(context.response)
log.info "Department name from response ${json.data.name}"
assert json.data.name == context.expand('${#TestCase#DEPARTMENT_NAME}'), 'Department name is not matched'
You may also edit the request, and add the value as ${#TestCase#DEPARTMENT_NAME} instead of current fixed value XAPIAS Department. So that you can just change the value of department name at test case level property, the same is sent in the request and the same is verified in the response.

Use JDBC teststep to run query directly into database:
Use Xpath assertion to Validate your Update API
Assertion 1
/Results/ResultSet[1]/Row[1]/FirstName
Expected result
Updated FirstName
Assertion 2
/Results/ResultSet[1]/Row[1]/LastName
Updated Last Name
In our project we do it in this way:
First we execute all the APIs.
Then we Validate all the new/updated data in database in DB Validation testcase.
Works well in highly integrated environment as well.
