Regression tests

This directory contains test that install each of the 3 Gloo flavours (gateway, ingress, and knative) and run regression tests against them.

Build test assets

The tests require that a Gloo Helm chart archive be present in the _test folder. This chart will be used to install Gloo to the GKE kube2e-tests cluster (by running glooctl install <deployment-type> -f -test/<chart-archive-name>).

To build the chart, execute the docker and build-test-assets make targets:

make GCLOUD_PROJECT_ID=solo-public BUILD_ID=my-local-build docker build-test-assets

The above command will also build all our docker images and deploy them to Google Container Registry (GCR), where the image references in the chart expect them to be.

Run test

To run the regression tests, your kubeconfig file must point to a running Kubernetes cluster. You can then start the tests by running the following command from this directory:

ginkgo -r

Although running tests in parallel should work, the fact that Gloo creates some cluster-scoped resources is a potential source of problems.

Test environment variables

The below table contains the environment variables that can be used to configure the test execution.

Name	Required	Description
RUN_KUBE2E_TESTS	Y	Must be set to 1, otherwise tests will be skipped
DEBUG	N	Set to 1 for debug log output
WAIT_ON_FAIL	N	Set to 1 to prevent Ginkgo from cleaning up the Gloo installation in case of failure. Useful to exec into inspect resources created by the test. A command to resume the test run (and thus clean up resources) will be logged to the output.

To run locally with kind:

kind create cluster
VERSION=kind ./ci/kind.sh
GO111MODULE=off go get -u github.com/onsi/ginkgo/ginkgo
make glooctl-darwin-amd64 # if you are on a mac
make glooctl-linux-amd64 # if you are on linux
# To run tests that require a cluster lock
ginkgo -r -failFast -trace -progress -race -compilers=4 -failOnPending -noColor ./test/kube2e/...
