Test coverage

Tests are done on CI https://gitlab.com/sylva-projects/sylva-core/-/pipelines/1772372755 :

without Kepler deployed, the test is skipped:

$ pytest ./tools/login-test/test_ui_playwright.py --browser firefox -v --tb=short

with Kepler deployed (🛠 misc), the test mgmt-GUIs-test is passed:

Get Kepler unit status 00:16

N.B. an intermediate step has to be added in Playwright to filter other dashboards (page.goto(grafana_url + "/dashboards?query=kepler")). Otherwise, playwright is unable to find Kepler dashboard link. (cf. failure screenshot)

Global config for deployment pipelines

• autorun pipelines
• allow failure on pipelines
• record sylvactl events

Notes:

• Enabling autorun will make deployment pipelines to be run automatically without human interaction
• Disabling allow failure will make deployment pipelines mandatory for pipeline success.
• if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
