BDD tests for Jenkins X using ginkgo

Prerequisits

• golang
• a Jenkins X installation

Running the BDD tests

Then to run all the test suites

go test -timeout 2h ./test/suite/...

Note that as some of the tests take quite a long time it's important to override the default go test timeout of 10m

Or you can run a specific suite, for example

go test -timeout 1h ./test/suite/spring

To enable verbose logging, add -v, for example

go test -timeout 1h -v ./test/suite/spring 

Environment variables

There are lots that can be set (see test/helpers/suite.go). Most of the settings are quite specific and need to be used explicitly in your test to apply.

Environment variable	Use
BDD_JX	Fully qualified path to jx binary to use. If not specified jx will use the $PATH to find the binary.
BDD_TIMEOUT_APP_TESTS	Timeout for Apps related test determining the time to wait for jx commands to complete. See apps.go
BDD_TIMEOUT_BUILD_COMPLETES	Timeout waiting for a build to complete, for example a quickstart build.
BDD_TIMEOUT_BUILD_RUNNING_IN_STAGING	Timeout waiting for a staging build appearing.
BDD_TIMEOUT_CMD_LINE	Timeout waiting for external command to complete.
BDD_TIMEOUT_DEVPOD	Timeout waiting for devpod to appear.
BDD_TIMEOUT_SESSION_WAIT	Timeout waiting for jx command to complete.
BDD_TIMEOUT_URL_RETURNS	Timeout waiting for a given URL to become available.
GIT_ORGANISATION	GitHub organization used as owner for created repositories.
GIT_PROVIDER_URL	Git provider URL.
JX_BDD_INCLUDE_APPS	Comma separated list of apps for which to test the app life cycle. Defaults to jx-app-jacoco:0.0.100
JX_DISABLE_DELETE_APP	Whether application created via quickstart test should be deleted.
JX_DISABLE_DELETE_REPO	Whether repositories created via quickstart test should be deleted.
JX_DISABLE_WAIT_FOR_FIRST_RELEASE	?
SLOW_SPEC_THRESHOLD	Ginkgo threshold for marking a spec as slow.

Running tests locally

When trying to run the tests locally against an existing cluster the following variables are in particular interesting:

• GIT_ORGANISATION to override the git organisation - by default the username of the pipeline user in the connected cluster
• BDD_JX to override the jx binary to use for executing jx commands
• JX_HOME to override the Jenkins X home directory, default ~/.jx
• KUBECONTEXT to point to a given cluster

Debugging tests in your IDE

Goland

Find the right _test.go file for the suite you want to run, and right-click Run ..._test.go, or choose Debug ..._test.go to debug it.

If it's a long running test, you may need to add the -timeout 1h argument, you can do that by editing the Run configuration and adding -timeout 1h to the Go Tool Arguments.

To enable verbose logging edit the Run configuration and adding -v to the Go Tool Arguments.

Visual Studio Code

Microsoft already has excellent general guidance for debugging Go in VS Code. Below is an example of how to set this up specifically for these BDD tests.

1. From the drop-down menus, select Debug --> Open Configurations. This should create a launch.json file for you, if there wasn't one already set up.

2. Some of the default settings for this file will be fine, but others need to be changed e.g. to set the timeut.. VS Code's Intellisense feature will let you hover over these settings and see possibilities.
