Squash TM test execution plan retrieval with a PEaC

Squash DEVOPS gives you the possibility to retrieve an execution plan for automated tests defined in Squash TM with a PEaC. The PEaC can be triggered by a Jenkins pipeline (see the corresponding page of this guide).

Focus

For this functionality to work properly, Test Plan Retriever plugin and Result Publisher plugin must be installed on the targeted Squash TM instance.

Prerequisites

A user belonging to the Test automation server group must exist in Squash TM.

Integration of the Squash TM execution plan retrieval step into a PEaC

The execution plan, iteration or test suite, must contain at least one ITPI (Iteration Test Plan Item, see the Squash TM glossary) linked to an automated test case, as described in the Squash AUTOM user guide.

In order to retrieve this execution plan from Squash TM with a PEaC, you need to call the corresponding generator action.

Here is a simple example of such a PEaC in JSON format:

{
    "apiVersion": "opentestfactory.org/v1alpha1",
    "kind": "Workflow",
    "metadata": {
        "name": "Simple Workflow"
    },
    "defaults": {
        "runs-on":"ssh"
    },
    "jobs": {
        "explicitJob": {
            "runs-on":"ssh",
            "generator":"tm.squashtest.org/tm.generator@v1",
            "with": {
                "testPlanUuid":"1e2ae123-6b67-44b2-b229-274ea17ad489",
                "testPlanType":"Iteration",
                "squashTMUrl":"https://squashtm.example.com/squash",
                "squashTMAutomatedServerLogin":"tfserver",
                "squashTMAutomatedServerPassword":"tfserver",
                "technologyLabels":{
                    "ranorex": ["windows","ranorex"],
                    "robotframework": ["linux","robotframework"],
                    "junit": ["linux","junit"]
                }
            }
        }
    }
}

A Squash TM generator step must contain the following parameters:

  • testPlanType: Defines the type of test plan to retrieve in Squash TM. Only the values Iteration and TestSuite are accepted.

  • testPlanUuid: This is the UUID (Universally Unique IDentifier, see the Squash TM documentation) of the requested test plan. It can be found in the Description block by clicking on the Information tab of the iteration or test suite in Squash TM.

  • squashTMUrl: URL of the targeted Squash TM.

  • squashTMAutomatedServerLogin: Name of the Test automation server group user to log into Squash TM.

  • squashTMAutomatedServerPassword: Password of the Test automation server group user to log into Squash TM.

[Optional fields]:

  • tagLabel: Specific to the Premium version - It refers to the name of the tag type custom field on which the test cases to retrieve are to be filtered. It is not possible to specify more than one.

  • tagValue: Specific to the Premium version - It refers to the value of the tag type custom field on which the test cases to retrieve are to be filtered. It is possible to specify multiple ones separated by "value2). There has to be at least one value specified for the test case to be taken into account.

Focus

If one of the two tagLabel or tagValue fields is present, the other one must also be specified.

  • technologyLabels: To use if you retrieve an execution plan containing tests which must be executed on different environments.
    It enables you to specify, for each automation framework, targeted environment execution's tags.
    They will be added to the ones specified in the job's runs-on attribute.
    For a technology, tags are defined by adding an entry to the field list with format "technology prefix": ["tag1", "tag2"]

Info

By default, jobs created by the Generator after retrieving an execution plan are tagged with the corresponding technology prefix (technology name in lower case with no space, for example "robotframework" for Robot Framework) in addition of the ones specified in Generator job's runs-on attribute.

Usage of the orchestrator with inception execution environment

OpenTestFactory, and therefore Squash DEVOPS, have a special execution environment called inception to use an alternative use mode for generator type jobs.

What is the purpose of inception environment ?

Usual execution process of a generator job is to retrieve an execution plan from Squash TM and then execute automated tests of this plan on dedicated execution environment. When an inception execution environment is used by a generator job, there is no test execution following execution plan retrievement. Instead, result publication step to Squash TM is run based on a set of reports sent upstream to the orchestrator.

How to use inception environment in a PEaC

Below is a workflow example in YAML format using inception execution environment and retrieving a Squash TM execution plan.

metadata:
  name: Test Inception
resources:
  files:
  - report1
  - report2
  - report3
jobs:
  prepare:
    runs-on: inception
    steps:
    - uses: actions/prepare-inception@v1
      with:
        report.html: ${{ resources.files.report1 }}
        output.xml: ${{ resources.files.report2 }}
        log.html: ${{ resources.files.report3 }}
  robot:
    runs-on: inception
    needs: [prepare]
    generator: tm.squashtest.org/tm.generator@v1
    with:
      squashTMUrl: https://squashtm.example.com/squash
      squashTMAutomatedServerLogin: ${{ variables.SQUASH_USER }}
      squashTMAutomatedServerPassword: ${{ variables.SQUASH_PASSWORD }}
      testPlanUuid: 1e2ae123-6b67-44b2-b229-274ea17ad489
      testPlanType: Iteration

There are several differences compared to the PEaC of the previous section:

  • The files section in the resources part: it lists external inputs sent to the orchestrator. Information published to Squash TM will be extracted from these resources.

  • A preparation job, called prepare in this example: it uses actions/prepare-inception@v1 action provider and allows to indicate what resource, usually generated by the test execution, matches with resources of the files section.

  • The generator job: it is very similar to the one of the previous section with two differences:

    • It uses inception environment in the runs-on field
    • It specifies that the preparation job is a prerequisite for its execution with the line needs: [prepare]

Such a PEaC can be run with the following command:

curl -X POST \
     -H "Authorization: Bearer ${TOKEN}" \
     -F workflow=@Squashfile \
     -F report1=@report1.html \
     -F report2=@report2.xml \
     -F report3=@report3.xml \
     -F variables="SQUASH_USER=${USER}\nSQUASH_PASSWORD=${PASSWD}" \
     http://orchestrator.example.com/workflows

Note in this command the parameters specifying the reports to be sent by the orchestrator to Squash TM.

A PEaC using inception execution environment can also be run from a Jenkins pipeline thanks to the Squash DEVOPS plugin step.

Squash TM parameters to exploit in an automated test

By executing a PEaC retrieving a Squash TM execution plan, Squash TM passes various pieces of information on execution plan items that can be exploited during test case execution.

For more information, please refer to the Squash TM parameters exploitation section of the Squash AUTOM documentation, as well as the dedicated section on the desired automation framework.

Info

Following frameworks can handle Squash TM parameters exploitation during test execution:

Results publication in Squash TM at the end of the execution

The nature of the results published in Squash TM at the end of the execution will depend on the usage of a Squash AUTOM Community or Squash AUTOM Premium licence.

Please refer to the Squash AUTOM user guide for more information.
