# This script runs the presubmit tests; it is started by prow for each PR.
# For convenience, it can also be executed manually.
# Running the script without parameters, or with the --all-tests
# flag, causes all tests to be executed, in the right order.
# Use the flags --build-tests, --unit-tests and --integration-tests
# to run a specific set of tests.

# Markdown linting failures don't show up properly in Gubernator resulting
# in a net-negative contributor experience.
# Tracked by https://github.com/knative/test-infra/issues/428

# If you call this script after configuring the environment variables
# $KNATIVE_SERVING_VERSION / $KNATIVE_EVENTING_VERSION with a valid release,
# e.g. 0.6.0, Knative Serving / Eventing of this specified version will be installed
# in the Kubernetes cluster, and all the tests will run against Knative
# Serving / Eventing of this specific version.
