+# 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 mizu@up9.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,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+Pass it to Mizu through the CLI option: `mizu tap -n sock-shop --contract catalogue.yaml`
+
+Now Mizu will monitor the traffic against these contracts.
+
+If an entry fails to comply with the contract, it's marked with `Breach` notice in the UI.
+The reason of the failure can be seen under the `CONTRACT` tab in the details layout.
+
+### Notes
+
+Make sure that you;
+
+- specified the `openapi` version
+- specified the `info.version` version in the YAML
+- and removed `servers` field from the YAML
+
+Otherwise the OAS file cannot be recognized. (see [this issue](https://github.com/getkin/kin-openapi/issues/356))

+# Testing guidelines
+
+## Generic guidelines
+* Use "[testing](https://pkg.go.dev/testing)" package
+* Write [Table-driven tests using subtests](https://go.dev/blog/subtests)
+* Use cleanup in test/subtest in order to clean up resources
+* Name the test func "Test<tested_func_name><tested_case>"
+
+## Unit tests
+* Position the test file inside the folder of the tested package
+* In case of internal func testing
+  * Name the test file "<tested_file_name>_internal_test.go"
+  * Name the test package same as the package being tested
+  * Example - [Config](../cli/config/config_internal_test.go)
+* In case of exported func testing
+  * Name the test file "<tested_file_name>_test.go"
+  * Name the test package "<tested_package>_test"
+  * Example - [Slice Utils](../cli/mizu/sliceUtils_test.go)
+* Make sure to run test coverage to make sure you covered all the cases and lines in the func  
+  
+## Acceptance tests
+* Position the test file inside the [acceptance tests folder](../acceptanceTests)
+* Name the file "<tested_command>_test.go"
+* Name the package "acceptanceTests"
+* Do not run as part of the short tests
+* Use/Create generic test utils func in acceptanceTests/testsUtils
+* Don't use sleep inside the tests - active check 
+* Running acceptance tests locally
+  * Switch to the branch that is being tested
+  * Run acceptanceTests/setup.sh
+  * Run tests (make acceptance-test)
+* Example - [Tap](../acceptanceTests/tap_test.go)
