---

Module 1

1.1 Inspect

• Inspect the saucectl configuration file listed below.
  .sauce/config-module-01.yml

  • What environment variables does it expect?
    • Make sure you have all the environment variables specified set.
  • What image does it use?
  • What is the resourceProfile key?
    • Hover over this key in the configuration file.
      • Did the schema validation overlay pop up?
  • Did you see any other configuration keys that might be useful?

1.2 Run

• Run the saucectl command below.
  • Describe what happened.
  • If successful, what did it do?
  • If unsuccessful, what does the error message say?
    • What does that mean?
    • How do you fix it?
  • What is a runID?

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-01.yml

---

Module 2

2.1a Inspect

• Inspect the saucectl configuration file listed below.
  .sauce/config-module-02-01.yml
  • Describe what it does.

2.1b Run

• Run the saucectl command below.
  • Describe what happened.
  • If successful, what did it do?
  • If unsuccessful, what does the error message say?
    • What does that mean?
    • How do you fix it?
    • What is the runID?
      • Write it down here.

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-02-01.yml

2.2 Artifacts

• Collect the log from the container.
  • Update the configuration file to download the error log.
  • Read about the configuration key named artifacts.
  • Make a copy of the existing configuration and add the needed key to save a custom artifact.
    • We want to collect the error log that was referenced in the console output.

This same configuration can be used to download custom reports or test artifacts that are written to the container.

saucectl run --region ${SAUCE_REGION}--config .sauce/config-module-02-02.yml

2.3 Download

• Re-run with the new configuration.
  • Where is the file?
    • Copy the runID from the last run.
    • Export the runID. export runID=
    • Run the command listed below and then open the log file.

saucectl imagerunner artifacts download ${runID} "*" --target-dir artifacts/runID-${runID}

2.4 Logs

• What does the log from the container tell us?
  • Is this different than what the log from saucectl told us?
  • Pull the console output for this run from saucectl.
    • Confirm the answer needed was not already provided.

saucectl imagerunner logs ${runID} 

2.5 Triage

• Where is the issue with the test?
  • How can we triage this issue further?
  • Can you collect all the available paths from the image?
  • Create a new configuration file.
    • This time change the entry point to run the command listed below.
      env

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-02-05-01.yml

• Try the command below next.
  • Run this new configuration.
  • What output do you collect?
  • What does this tell you?
  • Have you confirmed what the issue is?
  • Do you now think the issue is related to something else?
    ls -la demo-webdriverio

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-02-05-02.yml

• What if the output was truncated?
• What about running a script with multiple commands?
  • Update the configuration to send the output to a log.
  • Update the configuration to automatically download the log.

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-02-05-03.yml

• What did this configuration file do?
  • Did we update the image?
  • Will the script be there if I run a different configuration?
  • Where are the logs generated by this script downloaded?
  • Does it matter where I place the artifacts key in the runner configuration?
  • The artifacts key is in the configuration file, but where the are job assets? e.g. video, console.log, etc.

Note: saucectl can download job artifacts using the artifacts download command

---

Module 3

Up to this point...

• We have not used Docker.
• We have not built an image.
• We have not looked at a DOCKER file.
• We have launched containers on Sauce Orchestrate.

Let's do the same investigation on a local container. This provides us with an interactive session and will save a lot of time. What if you don't have access to the image?

Keep everything as close as possible to the original configuration.
Use the same variables passed in the saucectl configuration file.

3.1 Interactive Session on Local Container

• Run the command below.

# use this image
export imageName='suncup/photon-js:latest'

# start a shell
docker run -it \
    --platform linux/amd64 \
    --env SAUCE_USERNAME=${SAUCE_USERNAME} \
    --env SAUCE_ACCESS_KEY=${SAUCE_ACCESS_KEY} \
    --env SAUCE_BUILD_TYPE="Docker Local Dev" \
    ${imageName} \
    sh

• Where are you?
• What can you fix?
• What is the platform parameter and why is it set to linux/amd64?
  • Docker images can be built for different architectures and operating systems.
  • Try the commands below.
    uname -m
uname -o
    • What machine architecture are you using?
      • x86_64 is the same amd64.
      • arm64 is different.
    • What operating system are you using?

Sauce Orchestrate supports images built for the linux/amd64 platform.

3.2 Working Command on Local Container

• Go through all the steps from Module 2 in this interactive session.
  • Is the get-info.sh script there?
  • What did you find?
  • Are you able to run the test from the base directory?

3.3 Validate the Entrypoint on a Local Container

• Get the test to run directly from the container.

  • What should the entrypoint be?

3.4 Validate the Entrypoint on an Orchestrate Container

• Fix the configuration and re-run via saucectl.

saucectl run --region ${SAUCE_REGION} --config .sauce/config-module-03-01.yml

3.5 Module Recap

• What is the one thing needed to run these commands?
• What are you able to fix, change, or update?

Module 4 Orchestrate+ Test Suite and Complete Test Environment Bundle

This module provides example configuration for a test suite with sidecar containers.

• These sidecars are defined in the suite's services section.
• All the containers can be reached via localhost:port.
• This example also shows how to stream the console logs.

Inspect the saucectl configuration file listed below.
.sauce/config-module-04-01.yml

• What services are defined in the configuration?
• What does the Sauce Connect tunnel provide access to in this example?
• How are dependencies validated before the test suite starts?

4.1 Orchestrate+ Entire App & Sauce Connect

# saucectl support for live logs requires version 0.171.0 or later
saucectl --version

# export environment variables
env |grep SAUCE
#export SAUCE_REGION=
#export SAUCE_USERNAME=
#export SAUCE_ACCESS_KEY=
#export SAUCE_TUNNEL_NAME=


# run multi-service orchestrate example
saucectl run --live-logs --region ${SAUCE_REGION} --config .sauce/config-module-04-01.yml

# main suite will pause
#   launch a live browser session with tunnel
#       validate services are running as expected
#           open page http://localhost:80
#           open page http://localhost:8080/__admin/mappings

# allow suite to complete
#   check artifacts directory for logs 

4.2a Orchestrate+ Standalone Services & Sauce Connect

# export environment variables
env |grep SAUCE
#export SAUCE_REGION=
#export SAUCE_USERNAME=
#export SAUCE_ACCESS_KEY=

# tunnel name must be unique, adding the value to file to reference in 2nd shell
export SAUCE_TUNNEL_NAME="wiremock-net-$(uuidgen)" && printf '%s' ${SAUCE_TUNNEL_NAME} > my_tunnel_name

# run multi-service orchestrate example
# the main suite is the sauce connect instance + six wiremock instances as services
# 
# live logs are usuful for development and exploratory testing
#   console logs are also available via saucectl imagerunner logs
#   https://docs.saucelabs.com/dev/cli/saucectl/imagerunner/logs/
saucectl run --live-logs --region ${SAUCE_REGION} --config .sauce/config-module-04-02.yml

# start a new shell
env |grep SAUCE
#export SAUCE_REGION=
#export SAUCE_USERNAME=
#export SAUCE_ACCESS_KEY=

# set the tunnel name from the my_tunnel_name file we created earlier
export SAUCE_TUNNEL_NAME=$(head -n 1 my_tunnel_name)
echo ${SAUCE_TUNNEL_NAME}

# check sauce connect status, will only return id for running tunnels
# once the tunnel id is returned
#   it means the wiremocks were all started and passed the health check
#   and sauce connect is up and running
#
# the tunnel.lib is an API wrapper
#   you can re-implement or extend as needed
#   it calls methods documented at the link below
#   https://docs.saucelabs.com/dev/api/connect/ 
source ./usr/tunnel.lib
tunnel_id_get_by_name ${SAUCE_TUNNEL_NAME}


# start xcuitest/espresso tests
#   or other test suite
#   make sure to use the tunnel name as set earlier
#   
#   as you access the tunnel and wiremocks, log messages will show on the orchestrate run


# after your tests suite is complete
#   gracefully stop the orchestrate instance
#   the same library sourced earlier can be used to simplify this step
# 
# stopping the tunnel will also stop the orchestrate run and the wiremock instances
# json output will be returned to validate if the command was successful
tunnel_stop_by_name ${SAUCE_TUNNEL_NAME}


# the saucectl process in the first shell
#   which submitted the orchestreate run
#   should stop gracefully
#   and the orchestrate run should be marked as successfull
#
#   check the exit code to validate
#   echo $?

4.2b Async Mode Orchestrate+ Standalone Services & Sauce Connect

This is the same use case as 4.2, but we will invoke the Orchestrate saucectl process with the async parameter.
The health of the Orchestrate pod and post-run collection of the console output are operational critical.

This is just one method to demonstrate using the async option to suppport a synchronous pipeline. Other methods exist.
i.e. Shell job control is an excellent option. Use a method most familiar, comfortable, efficient for your team's DevOps processes and experiences.

Please see README-module-04b for the async example workflow.

4.3 Orchestrate+ Proxy Party Geo-IP Edition

Deploy multiple Sauce Connect instances where browsers and devices are proxied. Requires a WonderProxy account.

[[ -z ${SAUCE_USERNAME} || -z ${SAUCE_ACCESS_KEY} || -z ${SAUCE_REGION} ]] \
    && printf "\nPlease set environment variables for "SAUCE_USERNAME", "SAUCE_ACCESS_KEY", and "SAUCE_REGION".\n"

[[ -z ${WONDERPROXY_USER} || -z ${WONDERPROXY_TOKEN} ]] \
    && printf "\nPlease set environment variables for "WONDERPROXY_USER" and "WONDERPROXY_TOKEN".\n"

export SAUCE_TUNNEL_NAME="sc-monitor-$(uuidgen)"
saucectl run --live-logs --region ${SAUCE_REGION} --config .sauce/config-module-04-03.yml


# open sauce labs dashboard
# select tunnel before starting browser/device session

# stop the monitor sauce connect instance or cancel the orchestrate run


# swap the sc monitor instance for your automated tests suite
#   set the tunnelName config as noted in link below
#   values are in the orchestrate configuration
#   https://docs.saucelabs.com/dev/test-configuration-options/#tunnelname
