# Example: start a werkator test server watching a scratch repository with a fake build.
|
|
# This is the setup used for the manual UI/API smoke tests during development:
|
|
# a local bare origin (with a second branch for the Branches view), a slow fake
|
|
# build with live log output and a demo report artifact, and a fast poll
|
|
# interval — no Gitea, no credentials, no Docker.
|
|
#
|
|
# Usage:
|
|
# ./docs/examples/setup-werkator-testserver.sh
|
|
# BUILD_SECONDS=5 SERVER_PORT=18981 ./docs/examples/setup-werkator-testserver.sh
|
|
#
|
|
# While the server runs, trigger builds by pushing from the "work" clone:
|
|
# git -C ~/werkator-testserver/work commit --allow-empty -m "trigger build" && git -C ~/werkator-testserver/work push
|
|
# A commit message containing "[fail]" makes the fake build fail;
|
|
# pushing a new branch exercises the new-origin-branch path.
