BDD tests

Tests in this module are a rewrite and enhancement of the end-to-end tests available in the /test directory. They use Godog framework which is the official Cucumber BDD framework for Go and use Gherkin for writing test scenarios.

Tests also make use of the BDD Framework for Kubernetes which simplifies communication with a Kubernetes cluster. This framework is an extract of the original framework available at github.com/kiegroup/kogito-operator.

Run tests

Prerequisites:

• oc installed
• Minikube or OpenShift running
• ~/.kube/config targeting the cluster

Command to run tests has the following format:

$ make run-tests [key=value]*

You can set these optional keys:

• feature is a specific feature you want to run.
  If you define a relative path, this has to be based on the "test" folder as the run is happening there. Default are all enabled features from 'test/features' folder
  Example: feature=features/operator/deploy_quarkus_service.feature

• tags to run only specific scenarios. It is using tags filtering.
  Scenarios with '@disabled' tag are always ignored.
  Expression can be:

  • "@wip": run all scenarios with wip tag
  • "~@wip": exclude all scenarios with wip tag
  • "@wip && ~@new": run wip scenarios, but exclude new
  • "@wip,@undone": run wip or undone scenarios

  Complete list of supported tags and descriptions can be found in List of test tags

• concurrent is the number of concurrent tests to be run.
  Default is 1.

• timeout sets the timeout in minutes for the overall run. Default is 240 minutes.

• debug to be set to true to activate debug mode. Default is false.

• load_factor sets the tests load factor. Useful for the tests to take into account that the cluster can be overloaded, for example for the calculation of timeouts.
  Default is 1.

• ci to be set if running tests with CI. Give CI name.

• cr_deployment_only to be set if you don't have a CLI built. Default will deploy applications via the CLI.

• load_default_config sets to true if you want to directly use the default test config (from test/.default_config)

• format sets the Godog output format, possible values are 'pretty' or 'junit'. Default is junit.

• container_engine engine used to interact with images and local containers. Default is docker.

• domain_suffix domain suffix used for exposed services. Ignored when running tests on Openshift.

• http_retry_nb sets the retry number for all HTTP calls in case it fails (and response code != 500). Default is 3.

• olm_namespace Set the namespace which is used for cluster scope operators. Default is 'openshift-operators'.

• operator_image_tag is the Operator image full name.
• operator_installation_source Defines what source is used to install the SonataFlow operator. Available options are olm and yaml. Default is yaml.
• operator_catalog_image Specifies catalog image containing SonataFlow operator bundle. Needs to be specified when operator_installation_source is set to olm.
• use_product_operator Set true if you want to run tests using product operator.

• operator_yaml_uri Url or Path to operator.yaml file. Default is ../operator.yaml.

• show_scenarios sets to true to display scenarios which will be executed.
  Default is false.
• show_steps sets to true to display scenarios and their steps which will be executed.
  Default is false.
• dry_run sets to true to execute a dry run of the tests, disable crds updates and display the scenarios which will be executed.
  Default is false.
• keep_namespace sets to true to not delete namespace(s) after scenario run (WARNING: can be resources consuming ...).
  Default is false.
• namespace_name to specify name of the namespace which will be used for scenario execution (intended for development purposes).
• local_cluster to be set to true if running tests using a local cluster. Default is false.
• local_execution to be set to true if running tests in local using either a local or remote cluster. Default is false.

Logs will be shown on the Terminal.

To save the test output in a local file for future reference, run the following command:

make run-tests 2>&1 | tee log.out

Running BDD tests with the current branch

$ make
$ make container-build
$ podman tag quay.io/kiegroup/kogito-serverless-operator-nightly:latest quay.io/{USERNAME}/kogito-serverless-operator-nightly:latest
$ podman push quay.io/{USERNAME}/kogito-serverless-operator-nightly:latest
$ make run-tests cr_deployment_only=true local_cluster=true operator_image_tag=quay.io/{USERNAME}/kogito-serverless-operator-nightly:latest

NOTE: Replace {USERNAME} with the username/group you want to push to. Podman needs to be logged in to quay.io and be able to push to your username/group. If you want to use docker, just append BUILDER=docker to the make container-build command.

Running smoke tests

The BDD tests do provide some smoke tests for a quick feedback on basic functionality:

$ make run-smoke-tests [key=value]*

It will run only tests tagged with @smoke. All options from BDD tests do also apply here.

Running devMode tests

make run-tests cr_deployment_only=true local_cluster=true show_scenarios=true tags=devMode  namespace_name=my-namespace operator_image_tag=quay.io/kiegroup/kogito-serverless-operator-nightly:latest

If you want to have a more readable format, you can specify the format=pretty parameter. You can also specify your own operator image. Namespace is always created automatically, however, you can provide its name as in the command above, otherwise it will be automatically generated.
