Tests

Unit tests

Unit tests live side by side with the code they are testing and can be run with:

go test $(go list ./... | grep -v third_party/)
# or
make test-unit

End to end tests

Some prerequisites to run tests:

1. Spin up a kind/minikube cluster.

2. To run end to end tests, you will need to have a running Tekton pipeline deployed on your cluster, see Install Pipeline.

3. Next install Tekton Triggers in the cluster, see Install Triggers

Set environment variable TEST_CLUSTERTASK_LIST_EMPTY to any value if tests are run in an environment which contains clustertasks.

export TEST_CLUSTERTASK_LIST_EMPTY=empty

Set SYSTEM_NAMESPACE variable to appropriate value (say tekton-pipelines) based on the namespace where Tekton Pipelines system components reside within the Kubernetes cluster.

export SYSTEM_NAMESPACE=<namespace-name> (eg: export SYSTEM_NAMESPACE=tekton-pipelines)

Running

End to end tests live in this directory. By default go test will not run the end to end tests, it need -tags=e2e to be enabled in order to run these tests, hence you must provide go with -tags=e2e.

go build -o tkn github.com/tektoncd/cli/cmd/tkn
export TEST_CLIENT_BINARY=<path-to-tkn-binary-directory>/tkn ( eg: export TEST_CLIENT_BINARY=$PWD/tkn ) 

By default the tests run against your current kubeconfig context:

go test -v -count=1 -tags=e2e -timeout=20m ./test/e2e/...

You can change the kubeconfig context and other settings with the flags.

go test -v -count=1 -tags=e2e -timeout=20m ./test/e2e/... --kubeconfig ~/special/kubeconfig --cluster myspecialcluster

You can also use all of flags defined in knative/pkg/test.

Flags

• By default the e2e tests against the current cluster in ~/.kube/config using the environment specified in your environment variables.
• Since these tests are fairly slow, running them with logging enabled is recommended (-v).
• Using --logverbose to see the verbose log output from test as well as from k8s libraries.
• Using -count=1 is the idiomatic way to disable test caching
• The end to end tests take a long time to run so a value like -timeout=20m can be useful depending on what you're running

You can use test flags to control the environment your tests run against, i.e. override your environment variables:

go test -v -count=1 ./test/e2e/... --kubeconfig ~/special/kubeconfig --cluster myspecialcluster

One test case

To run one e2e test case, e.g. TestPipelinesE2E test, use the -run flag with go test

go test -v ./test/... -tags=e2e -run ^TestPipelinesE2E

Prerequisite to run make check and make generated

Ensure that golangci-lint and yamllint are installed on your development machine. If not then install them following golangci-lint and yamllint.

Next step will be to run

# For linting the golang and YAML files 
make check
# To check diff in goldenfile and [docs](https://github.com/tektoncd/cli/tree/main/docs), update and autogenerate them
make generated
