+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at bitwiseman@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

+
+## Using WireMock and Snapshots
+
+This project has started converting to using WireMock to stub out http responses instead of use live data.
+This change will allow tests to run in a CI environment without needing to touch github.com.
+The tests will instead serve previously recorded responses from local data files.
+
+### Running WireMock tests
+
+Example:
+
+`mvn install -Dtest=WireMockStatusReporterTest`
+
+This the default behavior.
+
+
+### Setting up credential
+
+1. Create an OAuth token on github.com
+2. Set the GITHUB_OAUTH environment variable to the value of that token
+3. Set the system property `test.github.useProxy` (usually like "-Dtest.github.useProxy" as a Java VM option)
+
+    `mvn install -Dtest.github.useProxy -Dtest=WireMockStatusReporterTest`
+
+4. The above should report no test failures and include the following console output:
+
+    `WireMockStatusReporterTest: GitHub proxying and user auth correctly configured for user login: <your login>`
+
+Whenever you run tests with `-Dtest.github.useProxy`, they will try to get data from local files but will fallback to proxying to github if not found.
+
+
+### Writing a new test
+
+Once you have credentials setup, you add new test classes and test methods as you would normally.
+Keep `useProxy` enabled and iterate on your tests as needed. Remember, while proxying your tests are interacting with GitHub - you will need to clean up your state between runs.
+
+When you are ready to create a snapshot of your test data,
+run your test with `test.github.takeSnapshot` ("-Dtest.github.takeSnapshot" as a Java VM option).  For example:
+
+    `mvn install -Dtest.github.takeSnapshot -Dtest=YourTestClassName`
+
+The above command would create snapshot WireMock data files under the path `src/test/resources/org/kohsuhke/github/YourTestClassName/wiremock`.
+Each method would get a separate director that would hold the data files for that test method.
+
+Add all files including the generated data to your commit and submit a PR.
+
+### Modifying existing tests
+
+When modifying existing tests, you can change the stubbed WireMock data files by hand or you can try generating a new snapshot.
+
+#### Manual editing of data (minor changes only)
+
+If you know what data will change, it is sometimes simplest to make any required changes to the data files manually.
+This can be easier if the changes are minor or when you development environment is not setup to to take updated snapshots.
+
+#### Generating a new snapshot
+
+For more most changes, it is recommended to take a new snapshot when updating tests.
+Delete the wiremock data files for the test method you will be modifying.
+For more significant changes, you can even delete the WireMock files for an entire test class.
+Then follow the same as when writing a new test: run with proxy enabled to debug, take a new snapshot when done, commit everything, and submit the PR.
