[raysunjello]

3 New Test Case Files Created:

dissociate-transit-gateway–policy-table.rst
get-transit-gateway-policy-table-associations.rst
get-transit-gateway-policy-table-entries.rst

More Example Scenarios Added to Existing Files:

Create-transit-gateway-route.rst: added blackhole route creation, –blackhole flag, with no destination/attachment ID.

Create-verified-access-endpoint.rst: added case of creating VA endpoint with load balancer options rather than network interface.

Create-traffic-mirror-session.rst: added case of creating session without –packet-length flag, allowing capture of complete packets when ran.

Create-verified-access-instance.rst: added case of creating instance with FIPS enabled. Added missing output to original test case.

Create-transit-gateway-connect-peer.rst: added case of creating a custom connect peer using –bgp-options rather than the default ASN.

Hi, thanks for contributing new testcases. I have added more instructions for running the test cases. Please try running it yourself and see if it works after adding your new testcases. Following the steps, new bash scripts should be generated, and you can verify if your test cases were successfully parsed and added to the new test scripts. Let me know if you have any questions. Thanks!
