# Build step fails

This scenario tests the controller API to simulate a build, when one
build step fails.

    SCENARIO build step fails

Set up the controller.

    GIVEN an RSA key pair for token signing
    AND controller config uses statedir at the state directory
    AND controller config uses https://blobs.example.com as artifact store
    AND controller config uses https://auth.example.com as authentication
    AND controller config uses https://notify.example.com as notify
    AND an access token for user with scopes
    ... uapi_pipelines_post
    ... uapi_projects_post
    ... uapi_projects_id_status_put
    ... uapi_projects_id_status_get
    ... uapi_projects_id_builds_get
    ... uapi_workers_id_get
    ... uapi_builds_get
    ... uapi_builds_id_get
    ... uapi_logs_id_get
    AND a running ick controller

Add up a project and its pipelines.

    WHEN user makes request POST /pipelines with a valid token and body
    ... {
    ...     "pipeline": "construct",
    ...     "actions": [
    ...         { "shell": "day 1", "where": "host" },
    ...         { "shell": "day 2", "where": "host" }
    ...     ]
    ... }
    THEN result has status code 201
    WHEN user makes request POST /projects with a valid token and body
    ... {
    ...     "project": "rome",
    ...     "pipelines": ["construct"]
    ... }
    THEN result has status code 201

Register a worker.

    GIVEN an access token for obelix with scopes
    ... uapi_workers_post
    ... uapi_work_post
    ... uapi_work_get
    WHEN obelix makes request POST /workers with a valid token and body
    ... {
    ... }
    THEN result has status code 201

Trigger build.

    WHEN user makes request GET /projects/rome/+trigger
    THEN result has status code 200

Worker wants work and gets the first step to run.

    WHEN obelix makes request GET /work
    THEN result has status code 200
    AND body matches
    ... {
    ...     "build_id": "rome/1",
    ...     "build_number": 1,
    ...     "log": "/logs/rome/1",
    ...     "worker": "obelix",
    ...     "project": "rome",
    ...     "parameters": {},
    ...     "action_id": "1",
    ...     "step": {
    ...         "action": "create_workspace",
    ...         "where": "host"
    ...     }
    ... }

Worker reports some build output. Note the exit code indicating
failure.

    WHEN obelix makes request POST /work with a valid token and body
    ... {
    ...     "build_id": "rome/1",
    ...     "action_id": "1",
    ...     "worker": "obelix",
    ...     "project": "rome",
    ...     "exit_code": 1,
    ...     "stdout": "",
    ...     "stderr": "eek!",
    ...     "timestamp": "2017-10-27T17:08:49"
    ... }
    THEN result has status code 201

Worker is next told to notify end of build.

    WHEN obelix makes request GET /work
    THEN result has status code 200
    AND body matches
    ... {
    ...     "build_id": "rome/1",
    ...     "build_number": 1,
    ...     "log": "/logs/rome/1",
    ...     "worker": "obelix",
    ...     "project": "rome",
    ...     "parameters": {},
    ...     "action_id": "4",
    ...     "step": {
    ...         "action": "notify"
    ...     }
    ... }

    WHEN obelix makes request POST /work with a valid token and body
    ... {
    ...     "build_id": "rome/1",
    ...     "action_id": "4",
    ...     "worker": "obelix",
    ...     "project": "rome",
    ...     "exit_code": 0,
    ...     "stdout": "",
    ...     "stderr": "eek!",
    ...     "timestamp": "2017-10-27T17:08:49"
    ... }
    THEN result has status code 201

The build has ended, and there's no more work to do.

    WHEN obelix makes request GET /work
    THEN result has status code 200
    AND body matches {}

User sees changed status.

    WHEN user makes request GET /workers/obelix
    THEN result has status code 200
    AND body matches 
    ... {
    ...     "worker": "obelix",
    ...     "doing": {}
    ... }

There's a build with a log.

    WHEN user makes request GET /builds
    THEN result has status code 200
    AND body matches
    ... {
    ...     "builds": [
