name: 'dhis2: e2e tests'

# Requirements:
#
# - Secrets:
#     GITHUB_TOKEN
#     CYPRESS_DHIS2_USERNAME
#     CYPRESS_DHIS2_PASSWORD
#
# - Customize environment variables:
#     BASE_URL_INSTANCES: Set the base url for the instances, e.g. https://test.e2e.dhis2.org
#     NAME_PATTERN_LEGACY_INSTANCES: Set the name pattern for your instances. {version} will be replaced by "[majorVersion].[minorVersion]"
#     NAME_PATTERN_DEV_INSTANCE: Set the name pattern for your dev instance. {version} will be replaced by "dev"
#     CYPRESS_CONTAINERS: Set the number of parallel Cypress job runs running for each backend version.
#     TRIGGER_LABELS: Set the labels that will trigger the workflow.
#
# - Set status check as required:
#     We recommend setting "call-e2e-tests-result / e2e-tests-success"  as a required step in your workflow.
#     This will ensure that one of the following must be true before the PR can be merged:
#       1) The tests have successfully run
#       2) The dev took a conscious decision not to run the tests (see e2e-tests-skip.yml)
#       3) They were skipped due to a special case (see e2e-tests-exception.yml)
