Jmeter has a function similar to the loadrunner checkpoint, which is the response assertion in the assertion.
1. Response assertion (match the returned text result accordingly)
Right-click on the request-->Add-->Assertion-->Response Assertion-->Add "pattern to be tested" as ${searchtxt}.
2. Assertion duration (judging how many milliseconds the response time cannot exceed)
Right-click on the request --> Add --> Assertion --> Assertion Duration.
3.Size Assertion (return data size judgment)
Right-click on the request --> Add --> Assertion --> Size Assertion.
4. Assertion Result (View Assertion Result)
Right-click Request-->Add-->Listener-->Assertion Result.
