Installation Guide

Security

Due to some security issues, it is strongly advised to use Squash TM 1.22.9 (or higher 1.X.Y), 2.2.0 (or higher 2.X.Y), or 3.0.0 (or higher 3.X.Y).

Squash Orchestrator†

Installation

Squash Orchestrator is a set of services running together. They may or may not run on the same machine, and they may or may not be started at the same time.

The only prerequisite is that the EventBus, the service they use to communicate together, is available when they launch.

To facilitate the installation of the orchestrator, an ‘all-in-one’ docker image is provided. It contains all core services (part of the OpenTestFactory Orchestrator) and some Squash specific services.

To get the latest image of Squash Orchestrator, use the following command:

docker pull squashtest/squash-orchestrator:latest

Preconizations for sizing the Docker container are:

  • 1 CPU
  • RAM: 1 GB (2 GB recommended)
  • disk: provide the capacity for storing the execution reports and their attachements for one hour of usage

Usage

Configuring the ‘all-in-one’ image

The execution of the following command will start the Squash Orchestrator using an existing execution environment, with self-generated trusted keys (which is not recommended in a production setup):

docker run -d \
         --name orchestrator \
         -p 7774:7774 \
         -p 7775:7775 \
         -p 7776:7776 \
         -p 38368:38368 \
         -e SSH_CHANNEL_HOST=the_environment_ip_or_hostname \
         -e SSH_CHANNEL_USER=user \
         -e SSH_CHANNEL_PASSWORD=secret \
         -e SSH_CHANNEL_TAGS=ssh,linux,robotframework \
          squashtest/squash-orchestrator:latest

It exposes the following services on the corresponding ports:

  • receptionnist (port 7774)
  • observer (port 7775)
  • killswitch (port 7776)
  • eventbus (port 38368)

Run the image in Premium mode

If you have a Premium license for Squash AUTOM and have deployed the Premium version of the Result Publisher Squash TM plugin, you must run Squash Orchestrator in Premium mode in order to have access to Premium behavior for result publishing in Squash TM. In order to do that, you have to add the following parameter in the Squash Orchestrator's run command: -e SQUASH_LICENCE_TYPE=premium

For more details about Squash Orchestrator configuration, please check the OpenTestFactory Orchestrator documentation on which Squash Orchestrator is based.

Orchestrator tools†

Installation

The orchestrator tools aim at simplifying the use of that one.
They require Python 3.8 or later. They are usable on Lunix, maxOS or Windows.

They can be installed using the following command:

pip3 install --upgrade opentf-tools

Overview of the tool capabilities

  • opentf-ready waits until the orchestrator is ready to accept workflows.

  • opentf-done waits until the orchestrator can be safely stopped (i.e. it has no more pending tasks).

  • opentf-ctl can be used to

    • start / track / stop a workflow
    • generate a signed token
    • list the subscriptions on the event bus
    • list the agents
    • generate / modify a configuration file

Squash AUTOM Premium exclusive micro-services

Installation

To install the Docker image of Squash AUTOM Premium exclusive micro-services, you must get the compressed image from Squash support service. Then you have to execute the following command:

docker load -i squash-autom-premium-3.0.2.tar.gz

Preconizations for sizing the Docker container are:

  • 1 CPU
  • RAM: 256 MB (1 GB recommended)
  • disk: provide the capacity for storing the execution reports and their attachements for one hour of usage

Usage

To run this Docker image, the following command must be used:

docker run -e BUS_HOST=<IP or DNS name of event bus> \
           -e BUS_PORT=<port> -e BUS_TOKEN=<JWT token> \
           -e EXTERNAL_HOSTNAME=<IP of premium micro-services> \
           --volume /path/to/truststore:/etc/squashtf/ \
           --volume /chemin/vers/dossier/temporaire:/tmp/ \
           squash-autom-premium:3.0.2

with:

  • BUS_HOST (mandatory): IP address or DNS name of EventBus service of the Squash Orchestrator with which micro-services communicate.

  • BUS_PORT (mandatory): port of EventBus service of the Squash Orchestrator with which micro-services communicate.

  • BUS_TOKEN (optionnal): JWT token accepted by the EventBus service of the Squash Orchestrator with which micro-services communicate.

  • EXTERNAL_HOSTNAME (optionnal): IP address or DNS name of Squash AUTOM exclusive micro-services.

  • --volume /etc/squashtf/: create a volume to a truststore with trusted public keys that can be used to validate JWT tokens. The volume must be created if JWT token validation is required to exchange messages between micro-services.

  • --volume /tmp/: create a volume to a folder shared with Squash Orchestrator to put temporary files generated while executing an execution plan.

OpenTestFactory Agent†

Installation

The OpenTestFactory agent is a Python application that is installed in the execution environment. It requires Python 3.8 or higher. It works on Linux, macOS, and Windows.

The agent is a simple script. It only has one external dependency, the well known requests library (it will be installed if not already present on the execution environment).

To install it, use the following command:

pip3 install --upgrade opentf-agent

You can test your installation by running the following command:

opentf-agent --help

Usage

Summary

$ opentf-agent --help
usage: opentf-agent [-h] --tags TAGS --host HOST [--port PORT] [--path_prefix PATH_PREFIX] [--token TOKEN] [--encoding ENCODING] [--script_path SCRIPT_PATH] [--workspace_dir WORKSPACE_DIR] [--name NAME] [--polling_delay POLLING_DELAY] [--liveness_probe LIVENESS_PROBE] [--retry RETRY] [--debug]

                      0 = try forever)
  --debug               whether to log debug informations.

Example

Assuming there is a Squash Orchestrator running on orchestrator.example.com, with a known token stored in the TOKEN environment variable, the following command will register the Windows-based execution environment and will possibly receive commands from Squash Orchestrator targeting windows and/or robotframework tagged environments:

chcp 65001
opentf-agent --tags windows,robotframework --host http://orchestrator.example.com/ --token %TOKEN%

The agent will poll the Orchestrator every 5 seconds, and will execute the received commands. The chcp command sets the console to Unicode. It is Windows-specific. It is not mandatory but may be needed depending on the test framework available in the execution environment.

Test environments†

Some test technologies require that some particular components are installed in the test environment, these ones are indicated in the page describing the specifities of the technology.

Squash TM configuration

Squash Orchestrator server declaration

In order to manually launch an execution plan from Squash TM, the Squash Orchestrator server that will execute the automated tests in the suitable environments has to be declared.
It is done in the Automation servers space of the Administration:

automation-server-declaration

automation-server-declaration

  • Name: The name of server, as it will appear in the Test Case workspace.

  • Type: Select squashAutom in the dropdown list.

  • Url: The address of the Squash Orchestrator Receptionist.

Attention

The Squash Orchestrator event bus service must be accessible by the same URL as the Receptionnist, on port 38368.

Once the server is created, you can set an authentication token.

token

token

Focus

A token is mandatory for the execution of automated tests from Squash TM. If the automation server does not require authentication token, you still have to set some value in Squash TM.

Squash TM project configuration

Once an automation server has been declared, it needs to be link to a Squash TM Project in order to be used for project's automated tests execution.

In order to do that, follow these steps:

  1. Click on [Administration] then click on [Projects].

  2. Select an existing project, scroll down to Test automation management.

    project-automation-block

  3. Click on No server. You'll see the list of available servers.

    project-automation-selection

  4. Choose the server and [Confirm].

  1. Click on [Administration] then click on [Projects].

  2. Select an existing project, scroll down to Test automation management.

    project-automation-block

  3. Click on No server. You'll see the list of available servers.

    project-automation-selection

  4. Choose the server and confirm.
