Contibute to ROSA CLI tests

Please read the structure and contribute code to the correct place

Contribute to day1
  1. Enable the configuration in profiles
  2. Mapping the configuration in ClusterConfig
  3. Define the userdata preparation function in data_preparation
  4. Call the functions in the GenerateClusterCreateFlags
Contribute to day2
  • Create the case in _rosa/tests/e2e/{feature name}test.go
  • Label the case with Day2
  • Label the case with importance Critical or High
  • Don't need to run creation step, just in BeforeEach step call function config.GetClusterID() it will load the clusterID prepared from env or cluster_id file
  • Code for day2 actions and check step
  • Every case need to recover the cluster after the case run finished unless it's un-recoverable
  • Case format should follow
    • main feature description in Describe level at the same time testing purpose in It level.
    • id of the case is included which will follow the fmt of [id:<id>]
    • Use By("") to describe the steps
    • An example as below
var _ = Describe("Create Machine Pool", func() {
  It("to hosted cluster with additional security group IDs will work - [id:72195]",func(){
    By("Prepare security groups")
    // security groups preparation code

    By("Create machinepool with security groups configured")
    // machinepool creation code

    By("Verify the machinepool is created with security groups")
    // machinepool security groups verification code
  })
}
  • The commit and PR should follow
    • Only one commit is allowed per PR, if multiple commits created please squash them with command git rebase -i HEAD~N(N is the commits number you would squashed)
    • The commit and PR title should follow rule of contributing-to-rosa
    • Case id must be included in the PR/commit title if new automated or updated. Comma-separated if multiple included in same PR/commit. For example <card id> | test: automated cases id:123456,123457
Labels

Label Design Doc: ROSA CLI Automation labels.

  • Label your case with the feature defined in features.go. The feature label is always defined at the top Description.
  • Label your case with the importance defined in importance.go. The importance lable is always defined on each test case.
  • Label your case with the runtime defined in runtime.go. The runtime lable is always defined on each test case.

If we meet the case fails CI all the time and we can't fix it in time, we can label the case with Exclude defined in category.go to exclude it from the CI list.

Running

Prerequisite

Please read repo's README.md For the test cases, we need $ make install to make the rosa command line installed to local

Users and Tokens
  1. Make local aws configuration finishing to launching the tests.
  2. Please login rosacli with the token:
  • $ rosa login --env staging --token $ROSA_USER_TOKEN
  1. Run rosa init to check all configurations are working well:
  • $ rosa init
Day1 cluster preparation
  1. Pick a profile for the cluster creation according to the configurations from
  1. Export the profile name as an environment variable
  • $ export TEST_PROFILE=<PROFILE NAME>
  1. Create cluster according to the profile configuration
  • $ ginkgo run --label-filter day1 tests/e2e --timeout 2h
  1. Wait for the cluster preparation finished

[!CAUTION] The profiles with a TODO is not supported yet

[!NOTE] Supported environment variables to override the profile configurations

  • SHARED_DIR if you have the env variable set, all output files will be put under it, otherwise it will create a dir output/${TEST_PROFILE}
  • ARTIFACT_DIR if you configured the env variable, files need to be archived will be recorded in it. Otherwise it will be recorded to dir output/${TEST_PROFILE}
  • CHANNEL_GROUP if it is set, the channel_group in profile configuration will be override
  • VERSION if it is set, the version in profile configuration will be override. Supported values
    • 4.15 it will pick the latest z-stream version in minor release of 4.15
    • latest it will pick the latest version in current channel_group
    • 4.16.0-rc.0 will match the exact version set
    • y-1 will pick a minor stream upgrade version
    • z-1 will pick a optional stream upgrade version
  • REGION if it is set, the region in profile configuration will be override. NOTE: rosa cluster with proxy will fail on region us-east-1. It's a known issue.
  • PROVISION_SHARD if it is set, a provision shard will be specified for cluster provision
  • NAME_PREFIX if it is set, all resources will be generated based with the name prefix to identify the created cluster created by you. Otherwise rosacli-ci will be used. For local testing, we should have it be set with your alias
  • CLUSTER_TIMEOUT if it is set, the process will exit if cluster cannot be ready in setting time. Unit is minute
Running a local CI test simulation

This feature allows for running tests through a case filter to simulate CI. Anyone can customize the case label filter to select the specific cases that would be run.

  1. To declare the cluster id, use the below variable
  • $ export CLUSTER_ID=<cluster_id>
  1. Run cases with the profile
    • Running cases based on label filter which to simulate CI jobs
      • $ ginkgo run --label-filter '(Critical,High)&&(day1-post,day2)&&!Exclude' tests/e2e
    • Run a specified case to debug
      • $ ginkgo run -focus <case id> tests/e2e
Resources destroy
  1. Export the profile name as an environment variable
  • $ export TEST_PROFILE=<PROFILE NAME>
  1. Destroy cluster and prepared user data based on the profile and the information recorded in the creation of the cluster
  • $ ginkgo -label-filter destroy tests/e2e
  1. Wait for the resources destroy finished

[!NOTE] Environment variables setting

  • SHARED_DIR if you have the env variable setting, resource destroy will read information from cluster-detail.json and resources.json under it, otherwise it will read the two files from output/${TEST_PROFILE}

Additional configuration

[!TIP] Set log level Log level defined in rosa/tests/utils/log/logger.go

Logger.logger.SetLevel()

Running with presubmit jobs

The presubmit jobs are used for validating the changes in the pull request before merging. The lifecycle of a presubmit job is create a cluster -> do testing -> release resources. The tester needs to select the corresponding configuration to trigger the job manually. These jobs are set to optional: true which means even if it is failed, it is not considered as a merging blocker.

Regularly, do testing focuses on the test case IDs that are gotten from the commit title in the format <card id> | test: automated cases id:123456,123457. If there is no test case ID, it will pick up the Critical ones. The testing results will be recorded in a junit.xml under rosa-test-e2e-pull-request/${ARTIFACT_DIR}.

Help

Type /test ? to list the defined jobs.

The following commands are available to trigger optional jobs:

    /test e2e-presubmits-pr-rosa-hcp
    /test e2e-presubmits-pr-rosa-hcp-byo-kms-oidc-auditlog
    /test e2e-presubmits-pr-rosa-hcp-private-proxy
    /test e2e-presubmits-pr-rosa-hcp-security-group
    /test e2e-presubmits-pr-rosa-non-sts
    /test e2e-presubmits-pr-rosa-sts
    /test e2e-presubmits-pr-rosa-sts-byo-kms-oidc-fips
    /test e2e-presubmits-pr-rosa-sts-localzone
    /test e2e-presubmits-pr-rosa-sts-private-proxy
    /test e2e-presubmits-pr-rosa-sts-security-group
