⛔️ DEPRECATED : FlakyBot

This bot is deprecated and is planned for shutdown August 6, 2025.

The Flaky Bot manages issues for failing tests.

If a test fails, the bot will open an issue for it.
If a test passes, the bot will close the corresponding issue.
If the test fails again:
- If the original issue is locked, the bot will open a new issue.
- If the original was closed more than 10 days before, the bot will open a new issue.
- Otherwise, the bot will reopen the original issue, mark it as flaky, then stop commenting and leave it up to a human to close.
If someone closes a flaky issue and the test fails again, the bot will reopen the issue or open a new one, depending on the issue state/age.
If the bot opens duplicate issues (sorry!), it will close the duplicates during the next run.
If 10 or more tests fail in the same package, they will all be grouped into a single issue. If there are already open issues for tests in the package, they will be left open until the corresponding test passes.

Note: the "package" is the part of the issue title before the :. If the package is wrong, please file an issue.

Issues or feature requests? Please file them on this repo.

Usage

General

Add the flakybot: quiet label to tell the bot to comment less on a particular issue.
If a test is detected as flaky, the bot will add the flakybot: flaky label, leave the issue open and stop commenting. A human will then have to fix and close the issue.

Installation

Install the bot on your repo. See https://github.com/apps/flaky-bot/. Issues will not start being filed until you finish the rest of the steps.

Note: if your repo is in googleapis, the bot is already installed.
Create sponge_log.xml xUnit XML files with your test results. There can be more than one, they can be in multiple directories, and the file names must end with sponge_log.xml.
If you're not already using Trampoline, add the Trampoline gfile directory to your Kokoro job. This contains the flakybot binary and service account that will be used to publish the logs.
```
gfile_resources: "/bigstore/cloud-devrel-kokoro-resources/trampoline"
```
Call the flakybot binary for nightly/continuous tests you want issues filed for. When you first add the bot, you may want to call the binary from the PR and confirm the bot works. If it doesn't work, file an issue on this repo with a link to the PR & test logs.
```
if [[ $KOKORO_BUILD_ARTIFACTS_SUBDIR = *"continuous"* ]]; then
  chmod +x $KOKORO_GFILE_DIR/linux_amd64/flakybot
  $KOKORO_GFILE_DIR/linux_amd64/flakybot
fi
```
- The path can either be linux_amd64/flakybot, darwin_amd64/flakybot, or windows_amd64/flakybot.exe.
  
  File an issue and/or send a PR to update the Makefile if you need a different platform.
- Flags:
  - -repo: The repo is automatically detected from either KOKORO_GITHUB_COMMIT_URL or KOKORO_GITHUB_PULL_REQUEST_URL. If those variables are not available, you must set the -repo flag. If your repo is github.com/GoogleCloudPlatform/golang-samples, set -repo to GoogleCloudPlatform/golang-samples.
  - -installation_id: If your repo is not part of googleapis or GoogleCloudPlatform, you must set -installation_id to the GitHub installation ID from step 1.
  - -commit_hash: The commit hash is used as a unique identifier for test invocations. If a test passes and fails for the same commit, it will be marked as flaky. The commit is automatically detected from the KOKORO_GIT_COMMIT environment variable. If that is not set, you must set -commit_hash to the commit this build is for.
  - -logs_dir: By default, the flakybot binary looks in the current working directory for log files ("."). If your logs are in a different directory, set -logs_dir to the absolute path to that directory. The directory is recursively searched.
  - -service_account: By default, the flakybot binary looks in the KOKORO_GFILE_DIR for the Trampoline service account. If that is not available (either you're running locally or not using Trampoline), you can set -service_account to the path to a service account that has Pub/Sub publish access to the repo-automation-bots topic passthrough.
  - -build_url: By default, the flakybot binary uses the KOKORO_BUILD_ID environment to detect the build URLs for the build. If the build is not on Kokoro, use the -build_url flag. [Markdown](links) are accepted.
Trigger a build and check the logs to make sure everything is working.

Configuration

By default, flakybot will create issues with priority: p1 label. You can configure the priority in the configuration file at .github/flakybot.yaml.

Here is an example of changing the label to priority: p2.

issuePriority: p2

Contributing

Instructions are provided in googleapis/repo-automation-bots for deploying and testing your bots.

This bot uses nock for mocking requests to GitHub, and snap-shot-it for capturing responses; This allows updates to the API surface to be treated as a visual diff, rather than tediously asserting against each field.

Running tests:

npm run test

To update snapshots:

npm run test:snap

If you have suggestions for how flakybot could be improved, or want to report a bug, open an issue! We'd love all and any contributions.

flakybot.go

This command is used to make it easy for people to send logs to the Flaky Bot (see instructions above).

To build/run it locally, clone the repo, cd to this directory, and run:

go build
./flakybot -repo=my-org/my-repo -installation_id=123 -project=my-project

To deploy the script, run:

make upload

This compiles the binary for the various platforms and copies them to the Trampoline GCS directory.
