What you expected to happen: make test should pass without any errors.

How to reproduce it (as minimally and precisely as possible):

• install go version >= 1.15
• run make test

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Network plugin and version (if this is a network-related bug):
• Others:

Thanks. Need to update the test certs under test/data (I think)
