test/test_activation.ps1

# This test installs emsdk and activates the latest toolchain using `--system` or `--permanent` flags,
# and checks if the environment variables and PATH are correctly updated. Set $env:SYSTEM_FLAG and $env:PERMANENT_FLAG to test each.
# If no flag is provided the process/shell values are tested. See the CI file for an example.
