test_json tests are failing with Assertion error. Can the test execution be made simpler

[pgbidkar]

Hi @jeking3 , We are working on making changes for 67U3, but all test_json tests are failing with Assertion error. Please can you provide quick readme to understand steps to rerecording and how expect files work.

First time recording tests work, but when we try to rerun tests fail with assertion error

Debugging is in progress. for future use it is good to have steps to reproduce

Thanks
