• I had searched in the DSIP and found no similar DSIP.

Motivation

After #16423, we can easily add integration case for master.
Some cases are already added at #16423, but the workflow might have many structure, and some task might influence the workflow runtime graph, so we need to add more cases.

• Switch task case [Improvement][Master] Adding integration testcases for switch task case in Master #16725
• Sub workflow task case
• Condition task case
• More failover case
• More workflow operation case
• Master event bus benchmark
