+# Higress E2E Tests
+
+Higress e2e tests are mainly focusing on two parts for now:
+
++ Conformance Test for Ingress API
++ Conformance Test for Gateway API
+
+## Ingress APIs Conformance Tests
+
+Higress provides make target to run ingress api conformance tests: `make e2e-test`. It can be divided into below steps:
+
+1. delete-cluster: checks if we have undeleted kind cluster.
+2. create-cluster: create a new kind cluster.
+3. kube-load-image: build a dev image of higress, and load it into kind cluster.
+4. install-dev: install higress-controller with dev image, and latest higress-gateway, istiod with helm.
+5. run-e2e-test:
+    1. Setup conformance suite, like define what conformance tests we want to run, in `e2e_test.go` / `higressTests Slice`. Each case we choose to open is difined in `test/ingress/conformance/tests`.
+    2. Prepare resources and install them into cluster, like backend services/deployments.
+    3. Load conformance tests we choose to open in `e2e_test.go` / `higressTests Slice`, and run them one by one, fail if it is not expected.
+
+### How to write a test case
+
+To add a new test case, you firstly need to add `xxx.go` and `xxx.yaml` in `test/ingress/conformance/tests`. `xxx.yaml` is the Ingress resource you need to apply in the cluster, `xxx.go` defines the HigressConformanceTest.
+
+And after that, you should add your defined HigressConformanceTest to `e2e_test.go` / `higressTests Slice`.
+
+You can understand it quickly just by looking at codes in `test/ingress/conformance/tests/httproute-simple-same-namespace.go` and `test/ingress/conformance/tests/httproute-simple-same-namespace.yaml`, and try to write one.
+
+## Gateway APIs Conformance Tests
+
+Gateway API Conformance tests are based on the suite provided by `kubernetes-sig/gateway-api`, we can reuse that,
+and descide what conformance tests we need to open. Conformance tests of Gateway API.
+
+This API covers a broad set of features and use cases and has been implemented widely.
+This combination of both a large feature set and variety of implementations requires
+clear conformance definitions and tests to ensure the API provides a consistent experience wherever it is used.
+
+Gateway API includes a set of conformance tests. These create a series of Gateways and Routes with the specified
+GatewayClass, and test that the implementation matches the API specification.
+
+Each release contains a set of conformance tests, these will continue to expand as the API evolves.
+Currently conformance tests cover the majority of Core capabilities in the standard channel, in addition to some Extended capabilities.
