 1. [OPTIONAL] Set `KUBECONFIG` environment variable to your Kubernetes configuration. If this is not set, Mizu assumes that configuration is at `${HOME}/.kube/config`
 2. `mizu` assumes user running the command has permissions to create resources (such as pods, services, namespaces) on your Kubernetes cluster (no worries - `mizu` resources are cleaned up upon termination)

+# 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)
