+# End to End Tests
+
+## Overview
+
+The end to end tests can be found in the ./github/workflows/end-to-end-test.yml action.
+
+- The tests are triggered by `workflow_dispatch` or on `pull_request` only when the label `PR: Safe to test 🧪` has been added to the PR.
+- The tests run against the environment `CSUTF`, which requires a manual approval to deploy.
+- The tests run as a matrix, targeting different OS, VCS, Terraform and Auth Methods.
+
+## Test Process
+
+The test follow this process:
+
+1. Check out the module from the PR merge branch.
+1. Generate an `inputs.json` file that is used to override the prompts in the `ALZ` PowerShell module.
+1. Install the `ALZ` PowerShell module.
+1. Get the latest version tag for the live accelerator module.
+1. Copy the `boostrap` and `template` folders into a folder named by the latest version tag.
+1. Run the `New-New-ALZEnvironment` function to deploy the terraform.
+1. Run a `terraform destroy` to clean up the environment.
+
+## Environment
+
+The tests use a set of environemnts to managed by the ALZ team. These are:
+
+- Azure:
+  - Tenant: CSU TF
+  - Subscription: csu-tf-devops
+  - User Assigned Managed Identity: alz-terraform-accelerator-cd-tests-identity (this has federated credentials)
+- Azure DevOps
+  - Organisation: microsoft-azure-landing-zones-cd-tests
+- GiHub
