Context:

1. Customer is asking for technical checks and test cases for ServiceNow platform, before moving to production.

2. This is more proactive test cases and code level checks before moving to Performance Load Test where customer is using Selenium for regression test and WPT for load running checks.

3. There are few specific modules that previously has performance challenges, like:

- Manager Landing Page

- Case load

- Shipment ID Search

- Case search

Questions: are there any test cases or checks that customer's technical team can do such that they are able to catch the performance issues on code level first before moving to performance load test?
