Integration tests

[christophe-kamphaus-jemmic]

What feature do you want to see added?

Currently this plugin does not have tests.

Add the following tests:

• Test download of otel-contrib + node_exporter from web (eg. using a mock http server)
• Test upload of otel-contrib + node_exporter from Jenkins plugin resources
• Test use of otel-contrib + node_exporter present on the agent PATH
• Test Grafana link
  • No link is present, if onMonit() is not used
  • Verify that a job using the onMonit() step has the link to the Jenkins settings (if Grafana link is not configured)
  • Verify that a job using the onMonit() step has the link to the Grafana dashboard (if configured in Jenkins settings)
    • Check that parameters are set correctly
• Test upload of metrics
  • Verify that host metrics are sent, in the test we could start a supporting otel collector that pushes metrics to InfluxDB, using InfluxDB Module - Testcontainers for Java and then assert after the test pipeline runs that metrics arrived in this DB.
  • Verify that custom OTEL config can be configured in Jenkins settings (eg. to use a custom label)
• Using two onMonit() in parallel on the same node works
• Using onMonit() in the options works
• Using onMonit { … } works
• Using onMonit works on different agents
  • macOs Arm / Amd64
  • Linux Arm / Amd64
  • Windows Amd64
• onMonit(debug: true) produces additional log output
