+# AvaAir E2E Flight Flow Test Suite
+
+This test suite exercises the **end-to-end customer journey** for AvaAir’s domestic flights (THR → MHD) using real API calls against a live environment (staging/production-like).
+
+It is intentionally designed to:
+
+* Validate **critical customer flows**: airport discovery, rules endpoints, flight search, booking, ticket issuance, and refund.
+* Run both **interactively** (developer manually enters OTP) and **fully automated** (CI with pre-configured OTP).
+* Be **readable and presentable** as a “production-grade” test harness.
+
+---
+
+## 1. High-level Architecture
+
+The test suite is composed of:
+
+* `conftest.py`
+  Global configuration and reusable fixtures shared across tests:
+
+  * Environment-driven configuration.
+  * Customer authentication (OTP flow).
+  * Authorization header fixture.
+  * Canonical THR → MHD search parameters.
+  * A small `api_wait` pacing helper for stabilizing async flows.
+
+* `test_flight_thr_mhd_e2e.py`
+  Actual test cases:
+
+  * IATA / airport discovery tests.
+  * Rules endpoints sanity checks.
+  * A full end-to-end scenario for:
+
+    * Search → Book → Wallet check → Issue → Refund penalty → Refund → Post-refund validation.
+
+The design intentionally centralizes configuration and “plumbing” in `conftest.py` so that individual tests remain concise and focused on business logic.
+
+---
+
+## 2. Environment & Configuration
+
+All configuration is driven through environment variables with reasonable defaults, so the suite can be used:
+
+* Quickly on a developer machine (with defaults).
+* Safely in CI (with explicit overrides).
+
+### 2.1 Base API URL
+
+```bash
+API_BASE_URL=http://192.168.19.19:8200/api/v1
+```
+
+* Default: `http://192.168.19.19:8200/api/v1`
+* Use this to point the suite to **staging**, **pre-prod**, or **production**.
+
+---
+
+### 2.2 Test User – Mobile & OTP
+
+```bash
+TEST_MOBILE_COUNTRY_CODE=98
+TEST_MOBILE_NUMBER=9014332990
+TEST_OTP_CODE=<optional pre-shared OTP>
+```
+
+* `TEST_MOBILE_COUNTRY_CODE` and `TEST_MOBILE_NUMBER` define the test customer account used for OTP login.
+* `TEST_OTP_CODE` controls how OTP is resolved:
+
+#### Interactive mode (local dev)
+
+If `TEST_OTP_CODE` is **not** set:
+
+* The suite sends an OTP to the configured mobile.
+
+* The developer is prompted in the terminal:
+
+  ```text
+  ➡️  Enter OTP received on the test device:
+  ```
+
+* The entered OTP is then used for `/users/otp/check`.
+
+#### Non-interactive mode (CI / automated)
+
+If `TEST_OTP_CODE` **is** set:
+
+* The suite **does not** prompt.
+* The value is used directly in the OTP verify call.
+* This enables fully headless execution in pipelines.
+
+---
+
+### 2.3 Booking Contact Info
+
+```bash
+TEST_BOOK_EMAIL=iamrezazoom@gmail.com
+TEST_BOOK_PHONE=9014332990
+```
+
+* Email and phone number used in `/customer/flight/book` payloads.
+* Defaults match the test user’s profile but can be overridden in more advanced setups.
+
+---
+
+### 2.4 Traveler Profile
+
+These fields define the passive traveler object used during booking:
+
+```bash
+TEST_TRAVELER_FIRST_NAME=REZA
+TEST_TRAVELER_LAST_NAME=ESMAEILI
+TEST_TRAVELER_GENDER=male
+TEST_TRAVELER_NATIONAL_CODE=0890500363
+TEST_TRAVELER_DATE_OF_BIRTH=1998-05-20
+TEST_TRAVELER_PLACE_OF_BIRTH=IRN
+```
+
+All of these have sensible defaults in `conftest.py`, but **in a real production-like setup** you should:
+
+* Override them with a dedicated test passenger identity.
+* Ensure the national ID and passport-related fields are valid for your environment.
+
+---
+
+## 3. Core Fixtures (conftest.py)
+
+### 3.1 `_today_plus_days(days: int) -> str`
+
+Utility that returns an ISO date (`YYYY-MM-DD`) relative to “today”:
+
+* Used to always search for flights **7 days in the future**.
+* Prevents hitting past or expired inventory.
+
+```python
+def _today_plus_days(days: int) -> str:
+    return (dt.date.today() + dt.timedelta(days=days)).isoformat()
+```
+
+---
+
+### 3.2 `api_wait` Fixture
+
+A small timing helper used to **pace** calls in E2E flows:
+
+```python
+@pytest.fixture
+def api_wait():
+    import time
+    def _do(seconds: float = 1.0) -> None:
+        time.sleep(seconds)
+    return _do
+```
+
+Why it exists:
+
+* Some backend operations are not purely synchronous:
+
+  * ticket issuance,
+  * wallet balance updates,
+  * ticket status changes.
+* Adding short, explicit waits between operations makes the E2E flow **deterministic** even on real environments.
+
+Usage example (from the E2E test):
+
+```python
+res_issue = requests.post(...)
+
+assert res_issue.status_code == 204
+api_wait(2.0)  # Let backend finalize issuance before querying tickets
+```
+
+---
+
+### 3.3 `customer_auth` Fixture
+
+This is the **entry point** into the tested system from a customer perspective.
+
+High-level behavior:
+
+1. Sends OTP request:
+
+   ```http
+   POST /users/otp/request
+   ```
+2. Resolves OTP from:
+
+   * `TEST_OTP_CODE` (if set), or
+   * interactive `input()` prompt.
+3. Validates OTP via:
+
+   ```http
+   POST /users/otp/check
+   ```
+4. Asserts the response contains:
+
+   * `auth_token`
+   * `refresh_token`
+   * `user`
+5. Returns an auth context dict:
+
+   ```python
+   {
+       "auth_token": "...",
+       "refresh_token": "...",
+       "user": {...},
+   }
+   ```
+
+If anything in this flow changes on the backend (contract change, field rename), the fixture fails **fast** with a clear assertion.
+
+---
+
+### 3.4 `auth_header` Fixture
+
+Thin wrapper that exposes the **canonical Authorization header**:
+
+```python
+@pytest.fixture(scope="session")
+def auth_header(customer_auth):
+    return {
+        "Authorization": f"Bearer {customer_auth['auth_token']}",
+        "accept": "application/json",
+    }
+```
+
+All tests consume this instead of re-implementing their own header logic.
+
+---
+
+### 3.5 `thr_to_mhd_search_params` Fixture
+
+Single source of truth for THR → MHD search parameters:
+
+```python
+@pytest.fixture(scope="session")
+def thr_to_mhd_search_params():
+    return {
+        "origin_iata": "THR",
+        "destination_iata": "MHD",
+        "flight_date": _today_plus_days(7),
+        "page": 1,
+        "page_size": 20,
+        "sort_option": "lowest-price",
+    }
+```
+
+Used by the E2E test to:
+
+* Always search a known route (THR → MHD).
+* Always target `today + 7` days.
+* Always sort by `lowest-price` to make the first itinerary deterministic.
+
+---
+
+## 4. Test Cases Overview (`test_flight_thr_mhd_e2e.py`)
+
+### 4.1 IATA / Airport Discovery Tests
+
+These cover the **airport search layer** exposed to the customer:
+
+#### `test_iata_domestic_default_list`
+
+* **Endpoint**: `GET /customer/iata`
+* **Parameters**:
+
+  * `keyword = ""`
+  * `is_international = false`
+* **Validations**:
+
+  * HTTP 200.
+  * `data` is a non-empty list.
+  * Both `THR` and `MHD` are present in the code list.
+
+Purpose:
+Ensures the default domestic IATA catalog is healthy and includes key airports.
+
+---
+
+#### `test_iata_search_origin_tehran`
+
+* **Endpoint**: `GET /customer/iata`
+* **Parameters**:
+
+  * `keyword = "tehran"`
+  * `is_international = false`
+* **Validations**:
+
+  * HTTP 200.
+  * `data` is a non-empty list.
+  * `THR` appears in results.
+
+Purpose:
+Validates keyword search for origin airports (Tehran).
+
+---
+
+#### `test_iata_search_destination_mashhad_excluding_origin`
+
+* **Endpoint**: `GET /customer/iata`
+* **Parameters**:
+
+  * `keyword = "mashhad"`
+  * `is_international = false`
+  * `other_iata_code = "THR"`
+* **Validations**:
+
+  * HTTP 200.
+  * `data` is a non-empty list.
+  * `MHD` appears.
+  * `THR` **does not** appear (origin must be excluded).
+
+Purpose:
+Confirms that destination search respects the “other airport” exclusion logic.
+
+---
+
+### 4.2 General & Refund Rules Test
+
+#### `test_general_and_refund_rules`
+
+Endpoints:
+
+* `GET /customer/setting/get/general-rules`
+* `GET /customer/setting/get/refund-rules`
+
+Validations:
+
+* `general-rules`:
+
+  * `data.general-rules` exists and is non-empty.
+* `refund-rules`:
+
+  * `data.refund_rules.domestic.data` is a non-empty list of objects.
+  * `data.refund_rules.international.data` the same.
+  * First item in each has `description` and `penalty`.
+
+Purpose:
+Quickly validates that the **configuration surface** (general rules and refund rules shown to customers) is available and structurally sound.
+
+---
+
+### 4.3 E2E: THR → MHD Single Adult Flow
+
+#### `@pytest.mark.e2e test_thr_mhd_single_adult_book_issue_refund_e2e(...)`
+
+This is the **flagship scenario**.
+
+It simulates a real customer:
+
+1. **Search flights (THR → MHD, D+7)**
+
+   * `POST /customer/flight/search`
+   * Validates:
+
+     * HTTP 200.
+     * Non-empty `itinerary_list`.
+     * First itinerary has:
+
+       * valid `flight_id`,
+       * at least one segment,
+       * segment from `THR` to `MHD`,
+       * `total_fare > 0`.
+
+2. **Book the first itinerary**
+
+   * `POST /customer/flight/book`
+   * Payload includes:
+
+     * Contact info (`email`, `phone_number`).
+     * Single ADT traveler (driven by env / defaults).
+   * Validates:
+
+     * HTTP 200.
+     * `id` (booking_id) is positive.
+     * `expires_at > 0`.
+     * `price > 0` (booking_price).
+
+3. **Verify wallet credit**
+
+   * `GET /admin/user/credit`
+   * Validates:
+
+     * HTTP 200.
+     * `credit` is numeric.
+     * `credit >= booking_price`.
+   * This step guarantees the issue step using wallet credit will succeed and is not blocked by insufficient balance.
+
+4. **Issue the ticket using wallet credit**
+
+   * `POST /customer/flight/book/{booking_id}/issue`
+   * Payload:
+
+     * `pay_with_credit = true`
+     * `pay_for = "ticket"`
+     * `platform = "mobile"`
+   * Validates:
+
+     * HTTP 204 (No Content).
+   * Followed by `api_wait(2.0)` to allow backend to finalize issuance.
+
+5. **Fetch active tickets and locate the issued one**
+
+   * `GET /customer/ticket` with:
+
+     * `is_past = false`
+     * `statuses = confirmed`
+   * Validates:
+
+     * HTTP 200.
+     * Non-empty ticket list.
+     * Ticket with `total == booking_price` exists.
+   * Extracts:
+
+     * `ticket_id`
+     * `ticket_traveler_id` (first traveler)
+     * `ticket_segment_id` (first segment)
+
+6. **Calculate refund penalty**
+
+   * `POST /customer/flight/refund-penalty`
+   * Payload:
+
+     * `ticket_segment_id`
+     * `[ticket_traveler_id]`
+   * Validations (for this no-penalty scenario):
+
+     * HTTP 200.
+     * Non-empty `data` array.
+     * First item:
+
+       * `payable > 0`
+       * `amount_that_should_pay_back_to_passenger > 0`
+       * `penalty_percent == 0`
+       * `amount_that_should_pay_back_to_passenger == booking_price`
+       * `ticket_traveler_id` matches the one sent.
+
+7. **Perform refund**
+
+   * `POST /customer/flight/refund`
+   * Payload:
+
+     * same `ticket_segment_id` and `ticket_traveler_id`.
+   * Validates:
+
+     * HTTP 200.
+   * Followed by `api_wait(2.0)` to allow status propagation.
+
+8. **Validate post-refund ticket state**
+
+   * `GET /customer/ticket` with:
+
+     * `is_past = true`
+     * `statuses = confirmed,refunded_partially,refunded`
+   * Locates the same `ticket_id`.
+   * Validates:
+
+     * `refund_status` is in `("refunded", "refunded_partially")`.
+
+Throughout the flow, the test logs each step with clear `[STEP X]` messages, making it easy to follow in CI logs or during a live demo.
+
+---
+
+## 5. Running the Tests
+
+### 5.1 Install dependencies
+
+```bash
+pip install pytest requests
+```
+
+(Or include them in your project’s `requirements.txt` / `poetry` / `pipenv`.)
+
+---
+
+### 5.2 Run all tests
+
+```bash
+pytest -q -s
+```
+
+* `-s` keeps the step-by-step console output:
+
+  * OTP flow logs,
+  * `[STEP X]` E2E narration.
+
+---
+
+### 5.3 Run only the E2E scenario
+
+The E2E test is marked with `@pytest.mark.e2e`. To run only that:
+
+```bash
+pytest -q -s -m e2e
+```
+
+To avoid Pytest’s “unknown mark” warning, add a `pytest.ini` in the repo root:
+
+```ini
+# pytest.ini
+[pytest]
+markers =
+    e2e: end-to-end tests that hit real external services (search, book, issue, refund)
+```
+
+---
+
+## 6. Production Safety Notes
+
+Because this suite can be pointed to a **live environment**:
+
+* It **does**:
+
+  * Create real bookings.
+  * Issue real tickets.
+  * Immediately refund them.
+
+* It **assumes**:
+
+  * The test account’s wallet has enough credit.
+  * The fare and policy selected result in **zero penalty** for the scenario.
+
+Recommendations:
+
+* Use a **dedicated test customer** with:
+
+  * Preloaded credit.
+  * No penalty restrictions.
+* Run E2E tests:
+
+  * On staging/pre-prod when possible.
+  * On production only as part of **controlled smoke** runs.
+
+---
+
+## 7. Summary
+
+This test suite gives you:
+
+* A **high-signal E2E validation** of the critical THR → MHD domestic flow.
+* A set of **supporting tests** for IATA and rules configuration.
+* A **presentable**, narrative output that clearly shows each phase:
+
+  * Authentication
+  * Discovery
+  * Booking
+  * Wallet validation
+  * Issuance
+  * Refund calculation
+  * Final refund state verification
