Test cases

The following is the list of test cases for the proxy config overrides feature (linkerd/linkerd/#2471).

auto-inject create

• Specify the config annotations in the pod template. Expect pod's proxy config to be overridden.
• Specify the config annotations in the namespace. Expect effects on all workloads in the same namespace.

auto-inject update

1. Deploy a workload with no config annotations.

The following are test cases for linkerd/linkerd2#2987, which introduces global resources checks to linkerd check --pre and linkerd install.

Single control plane installation:

bin/linkerd version --client
Client version: git-b8ba3b26

# expect pre-check to succeed
bin/linkerd check --pre
bin/linkerd check --pre -l linkerd-dev
