Kiwi TCMS: Test runner plugin specification

Happy Monday testers! Kiwi TCMS needs your help! We are looking for developers who
wish to create plugins for popular test runners that will record test results
in Kiwi TCMS! Initially we are looking for plugins for Python’s unittest,
Django
and JUnit!

What is a test runner?

When working with automated testing you have several components:

  • A test module (or test script), e.g. test_models.py which contains
    tests for your software;
  • A test framework, e.g. Python nose, which provides the structure
    for test classes and methods and assert methods to use;
  • A test runner, which knows how to discover your test scripts, load them,
    execute the testing scenarios inside of them and report the results.

Very often all of the components above live together inside the testing framework
but don’t need to. For example the standard unittest module in Python
provides a test runner but there are also nose and py.test and Django provides
its own test runner that knows how to work with the database.

Workflow organization

Once you agree to writing a plugin we are going to create a separate GitHub
repository where you will be granted write privileges making you an independent
contributor to the Kiwi TCMS project!

Design and architecture of the plugin is up to you, following the practices
established by the testing framework in question. You will also have to create
a test suite for your plugin based on the specification below.

You are expected to use
demo.kiwitcms.org while working on the
plugin and afterwards. This is known as eating your own dog food!

For Python we provide the tcms-api module which already takes care of the
communications layer. For other languages you will have to create this layer or
depend on other open source libraries that provide a XML-RPC or JSON-RPC
client!

You can use
this gist
for inspiration!

Behavior Specification

Please use the comments section to discuss unclear behavior and missing scenarios!

    SUMMARY: Will use configuration file if it exists
    GIVEN: the file ~/.tcms.conf exists
    WHEN: plugin initializes
    THEN: the plugin will log an info message, read the file and
    THEN: configure TCMS_API_URL, TCMS_USERNAME, TCMS_PASSWORD
          variables with the respective values


    SUMMARY: Will use ENVIRONMENT if configuration file doesn't exist
    GIVEN: the file ~/.tcms.conf does not exists
    WHEN: plugin initializes
    THEN: the plugin will read configuration from environment and configure
          the following variables/class members:
          TCMS_API_URL, TCMS_USERNAME and TCMS_PASSWORD


    SUMMARY: Will exit if TCMS_API_URL not configured
    GIVEN: TCMS_API_URL variable is empty
    WHEN: plugin initializes
    THEN: log a warning message and exit
    AND: depending on the test runner framework set exist status 1


    SUMMARY: Will exit if TCMS_USERNAME not configured
    GIVEN: TCMS_USERNAME is empty
    WHEN: plugin initializes
    THEN: log a warning message and exit
    AND: depending on the test runner framework set exist status 1


    SUMMARY: Will exit if TCMS_PASSWORD not configured
    GIVEN: TCMS_PASSWORD is empty
    WHEN: plugin initializes
    THEN: log a warning message and exit
    AND: depending on the test runner framework set exist status 1


    SUMMARY: Will re-use existing TestPlan if configured
    GIVEN: TCMS_RUN_ID environment variable is not empty
    WHEN: plugin initializes
    THEN:  this will be the Current_TestRun record to which the plugin is
           going to add test execution results
    AND: Current_TestPlan document in which the plugin will
           search for test cases becomes Current_TestRun.plan


    SUMMARY: Will create new TestPlan & TestRun if TCMS_RUN_ID not configured
    GIVEN: TCMS_RUN_ID environment variable is empty
    THEN: plugin will create a new TestPlan in Kiwi TCMS with attributes:
        name='Automated test plan for %(product)'
        product='%(product)'
        product_version='%(version)'
        type='Unit'
    WHERE: %(product) is a placeholder for TCMS_PRODUCT==TRAVIS_REPO_SLUG==JOB_NAME
           %(version) is a placeholder for TCMS_PRODUCT_VERSION==TRAVIS_COMMIT==TRAVIS_PULL_REQUEST_SHA==GIT_COMMIT
    THEN: plugin will crate a new TestRun in Kiwi TCMS with attributes:
        summary='Automated test run ....'
        plan=Current TestPlan
        build='%(build)'
        manager=TCMS_USERNAME
    WHERE: %(build) is a placeholder for TCMS_BUILD==TRAVIS_BUILD_NUMBER==BUILD_NUMBER
    Environment variables are specified in:
    https://docs.travis-ci.com/user/environment-variables#default-environment-variables
    https://wiki.jenkins.io/display/JENKINS/Building+a+software+project#Buildingasoftwareproject-belowJenkinsSetEnvironmentVariables

    SUMMARY: Will not create duplicate Product, Version & Build if they already exist
    GIVEN: TCMS_RUN_ID is not configured
    AND: %(product) exists
    AND: %(version) exists
    AND: %(build) exists
    WHEN: plugin tries to auto-create TestPlan and TestRun
    THEN: plugin will re-use %(product), %(version) and %(build) from the database
    AND: not try to auto-create them


    SUMMARY: Will auto-create Product, Version & Build if they don't exist
    GIVEN: TCMS_RUN_ID is not configured
    AND: %(product) doesn't exist
    AND: %(version) doesn't exist
    AND: %(build) doesn't exist
    WHEN: plugin tries to auto-create TestPlan and TestRun
    THEN: %(product), %(version) and %(build) be created automatically


    SUMMARY: Unit test names are added to TestPlan
    GIVEN: we have good plugin configuration
    WHEN: plugin loops over unit tests emitted by the test runner
    THEN: plugin will check Current_TestPlan for a TestCase with the same name
    AND: if test case doesn't exist in Current_TestPlan
    THEN: it will be added to Current_TestPlan
    hint: it is probably best to process all unit test results at the end!


    SUMMARY: Unit test names are added to TestRun
    GIVEN: we have good plugin configuration
    WHEN: plugin loops over unit tests emitted by the test runner
    THEN: plugin will check Current_TestRun for a TestCaseRun object which matches
          the current unit test name
    hint: (or Current_TestCase object from previous scenario, depending on implementation)
    AND: if such TestCaseRun doesn't exist in Current_TestRun
    THEN: it will be added to Current_TestRun
    hint: it is probably best to process all unit test results at the end!


    SUMMARY: Current_TestRun is updated with unit test results
    GIVEN: we have good plugin configuration
    WHEN: plugin loops over unit tests emitted by the test runner
    THEN: plugin will check Current_TestRun for a TestCaseRun object which matches
          the current unit test name
    hint: (or Current_TestCase object from previous scenario, depending on implementation)
    AND: if TestCaseRun object exists in Current_TestRun
    THEN: its status will be updated with the execution result coming from the test runner
    hint: it is probably best to process all unit test results at the end!

Happy testing!
