+# 2. Add any additional environment variables as needed
+# 3. To attach S3 IAM policies from shared state:
+#    - Uncomment the S3 policy attachment section below
+#    - Update the policy_arn to match the output from shared/main.tf
+#    - Available shared outputs (examples):
+#      - data.terraform_remote_state.shared.outputs.condition_etl_s3_read_arn
+#      - data.terraform_remote_state.shared.outputs.postcode_splitter_s3_read_arn
+# 4. To create a NEW S3 policy:
+#    - Add a new module "lambda_s3_policy" in shared/main.tf using the
+#      s3_iam_policy module (see examples in shared/main.tf)
+#    - Then reference it here using data.terraform_remote_state.shared.outputs

+# 🧪 Running Tests in PyCharm (macOS + pytest-postgresql)
+
+Our test suite uses `pytest` and `pytest-postgresql`, which
+automatically spins up a temporary PostgreSQL instance.
+
+On Linux (including GitHub Actions), PostgreSQL binaries are installed
+in standard system locations.\
+On macOS (Homebrew), they are not --- so PyCharm needs a small
+configuration tweak to locate `pg_ctl`.
+
+This guide explains how to run and debug tests locally in PyCharm
+without modifying test code.
+
+------------------------------------------------------------------------
+
+## ✅ Prerequisites
+
+1. Install PostgreSQL via Homebrew:
+
+``` bash
+brew install postgresql
+```
+
+2. Confirm `pg_ctl` exists:
+
+``` bash
+which pg_ctl
+```
+
+Typical output:
+
+    /opt/homebrew/bin/pg_ctl
+
+------------------------------------------------------------------------
+
+# 🚀 Running Tests in PyCharm
+
+## Step 1 --- Create a PyCharm pytest Run Configuration
+
+1. Open the test file.
+2. Click the green ▶ next to the test.
+3. Choose **"Edit Run Configuration..."**
+
+You should see something like:
+
+- **Target:** `backend/export/tests/test_export.py`
+- **Working directory:** Project root (e.g.`Model/`)
+
+------------------------------------------------------------------------
+
+## Step 2 --- Add Required Override (macOS Only)
+
+In the Run Configuration:
+
+### ➜ "Additional Arguments"
+
+Add:
+
+    --override-ini=postgresql_exec=/opt/homebrew/bin/pg_ctl
+
+This tells `pytest-postgresql` where `pg_ctl` lives on macOS.
+
+Without this, PyCharm may fail with:
+
+    ExecutableMissingException: Could not found pg_config executable
+
+------------------------------------------------------------------------
+
+## Step 3 --- Run or Debug
+
+You can now:
+
+- Click ▶ Run\
+- Click 🐞 Debug\
+- Set breakpoints normally
+
+The temporary PostgreSQL instance will start automatically.
+
+------------------------------------------------------------------------
+
+# 🔍 Why This Is Needed
+
+`pytest-postgresql` defaults to a Linux-style path:
+
+    /usr/lib/postgresql/<version>/bin/pg_ctl
+
+That path exists on Ubuntu (CI), but not on macOS.
+
+On macOS, Homebrew installs PostgreSQL in:
+
+    /opt/homebrew/bin/
+
+The `--override-ini` flag safely overrides the executable path
+**locally**, without modifying:
+
+- test files\
+- `conftest.py`\
+- `pytest.ini`\
+- CI configuration
+
+This ensures:
+
+- ✅ Tests still work in GitHub Actions\
+- ✅ Tests still work for Linux users\
+- ✅ macOS developers can debug in PyCharm\
+- ✅ No repository-specific hacks are required
+
+------------------------------------------------------------------------
+
+# 🛠 Optional: Using a Local `.env` File
+
+If you prefer not to hardcode the override in the run configuration:
+
+1. Create a local file:
+
+```{=html}
+<!-- -->
+```
+
+    .env.local
+
+2. Add:
+
+```{=html}
+<!-- -->
+```
+
+    PYTEST_ADDOPTS=--override-ini=postgresql_exec=/opt/homebrew/bin/pg_ctl
+
+3. In PyCharm:
+    - Open the Run Configuration
+    - Add `.env.local` under **"Paths to .env files"**
+
+------------------------------------------------------------------------
+
+# 🧪 Running Tests via Terminal (Recommended for CI Parity)
+
+For normal execution outside PyCharm:
+
+``` bash
+make test
+```
+
+These already work without additional configuration.
+
+------------------------------------------------------------------------
+
+# 🧠 Summary
+
+Environment Works Without Override? Needs `--override-ini`?
+  ------------------------ ------------------------- -------------------------
+GitHub Actions (Linux)   ✅ Yes ❌ No
+Linux local ✅ Yes ❌ No
+macOS terminal (tox)     ✅ Yes ❌ No
+macOS PyCharm debugger ❌ No ✅ Yes

+## Checklist for adding a new Lambda
+
+### 1. Create the Lambda scaffold
+- Copy the template:
+
+  `cp -r lambda/_template lambda/<lambda_name>`
+
+---
+
+### 2. Add infrastructure prerequisites (shared stack)
+- Add a new ECR repository in:
+
+  infrastructure/terraform/shared/main.tf
+
+- Create a PR to deploy this to main then dev in order to deploy the shared stack
+
+- Verify the ECR repository exists in AWS
+
+---
+
+### 3. Add Docker build configuration
+- Create a `Dockerfile` for the Lambda
+- Verify the Dockerfile path and build context
+- Add a new image build job in `deploy_terraform.yml` using `_build_image.yml`
+
+---

-## Checklist for adding a new Lambda
-
-### 1. Create the Lambda scaffold
-- Copy the template:
-
-  `cp -r lambda/_template lambda/<lambda_name>`
-
----
-
-### 2. Add infrastructure prerequisites (shared stack)
-- Add a new ECR repository in:
-
-  infrastructure/terraform/shared/main.tf
-
-- Create a PR to deploy this to main then dev in order to deploy the shared stack
-
-- Verify the ECR repository exists in AWS
-
----
-
-### 3. Add Docker build configuration
-- Create a `Dockerfile` for the Lambda
-- Verify the Dockerfile path and build context
-- Add a new image build job in `deploy_terraform.yml` using `_build_image.yml`
-
----
-
-### 4. Wire the Lambda deploy job (CI)
-- Add a deploy job using `_deploy_lambda.yml`
-- Ensure the deploy job depends on the image build job
-

-### 5. Deploy
-- Push changes to GitHub
