OpenShift Installer Smoke Tests

This directory contains all smoke tests for OpenShift Installer. The smoke tests are a set of Golang test files that perform minimal validation of a running OpenShift cluster.

Getting Started

The smoke tests assume a running OpenShift cluster, so before running any tests:

  1. create a OpenShift cluster; and
  2. download the cluster's kubeconfig to a known location.

Running

The smoke tests only require one parameter: the file path of the cluster kubeconfig. Export the following variable to parameterize the smoke tests:

export SMOKE_KUBECONFIG=/path/to/kubeconfig

Compile the smoke test binary from the root directory of the project:

bazel build smoke_tests

The tests can then be run by invoking the go_default_test binary in the bazel-bin/tests/smoke/linux_amd64_pure_stripped directory.

Note: the go_default_test binary accepts several flags available to the go test command; to list them, invoke the go_default_test binary with the -help flag.

Cluster Suite

The cluster test suite runs a series of tests designed to verify the overall health of the cluster and ensure that all expected components are present. The cluster test suite requires additional parameters:

  • the number of nodes in the cluster;
  • the paths of manifests deployed on the cluster; and
  • whether or not to test for experimental manifests.

Export the following environment variables to parameterize the cluster tests:

export SMOKE_NODE_COUNT=3
export SMOKE_MANIFEST_PATHS=/path/to/kubernetes/manifests
export SMOKE_MANIFEST_EXPERIMENTAL=true

To run the cluster test suite, invoke the smoke test binary with the -cluster flag. To run the cluster suite verbosely, add the -test.v flag:

bazel-bin/tests/smoke/linux_amd64_pure_stripped/go_default_test -cluster -test.v
