# Goal: Implement Live HTTP Integration Tests for cdd-python-all
1+
# Local Test Fixes Required
22

3-
We have recently upgraded our central E2E test harness (`../local-test.sh`). The harness now includes a **Coverage Hook** and a **Chaos Audit**.
3+
The integration tests for this toolchain currently fail when running natively against the Stoplight Prism mock server (`./local-test.sh only-test` with `ONLY_TEST=cdd-python-all`).
44

5-
Currently, the test suites generated by cdd-python-all only perform local instantiations or mocked assertions (e.g., `expect(service).toBeDefined()`). As a result, the new test harness fails the build because it detects 0% HTTP traffic coverage reaching the Docker `petstore_server`.
5+
## Instructions
6+
1. Run the test locally for this specific language using:
7+
`cd .. && ONLY_TEST=cdd-python-all ./local-test.sh only-test`
8+
2. Observe the output. The failure is typically caused by one of the following:
9+
* **401 Unauthorized:** The generated SDK tests are not injecting the required `api_key` or OAuth headers that the Swagger Petstore schema demands. Prism enforces security constraints strictly.
10+
* **400 / 422 Unprocessable Entity:** The generated SDK is sending incorrectly formatted JSON or invalid parameters for the mock server.
11+
* **404 Not Found / Configuration Issues:** The SDK might be querying the wrong base URL or missing the `/v2` base path prefix.
12+
* **Coverage Missing:** The generated tests might not be covering all endpoints. Check if the toolchain's block in `local-test.sh` suppresses test exit codes with `|| true`. If so, remove them, fix the tests so they actually pass, and ensure every endpoint has a generated test.
13+
3. Update the generator templates/AST extractors in this repository to resolve the issue.
14+
4. Verify your changes by ensuring `cd .. && ONLY_TEST=cdd-python-all ./local-test.sh only-test` passes successfully (including the coverage validation and chaos saboteur audits).
615

7-
### Your Task:
8-
Modify the code generator templates inside this directory (`cdd-python-all`) so that the resulting SDK test suite dispatches **real, live network requests** against all endpoints defined in the OpenAPI spec.
16+

## Official Swagger Java Server Native Logs Update
18+
A recent test run against the official JVM swagger-petstore backend yielded new failure patterns. Please address these specifically:
919

10-
**Requirements for the Generated Tests:**
11-
1. **Target URL:** All requests must target `http://localhost:8080/v2`.
12-
2. **Payloads:** Use dummy payloads that fulfill the schema requirements (strings, ints, etc.) so the endpoints execute successfully.
13-
3. **Assertions:** The generated tests must assert that the HTTP Status Code is valid and that the payload successfully deserializes. (If they don`t, the Chaos Audit in the harness will intentionally fail your build).
14-
15-
### How to Verify Your Work:
16-
Run the overarching E2E harness restricted to your language from the root directory:
17-
```bash
18-
cd ..
19-
ONLY_TEST=cdd-python-all ./local-test.sh only-test
20-
```
21-
22-
If your generator is correctly outputting live network calls for every endpoint, the `verify_coverage.py` script will report **"Coverage Validation Passed: 100% of endpoints were tested."**
20+
The Python SDK fails the Coverage Validation stage due to untested endpoints (e.g., `PUT /v2/pet`, `GET /v2/store/inventory`). Add the missing endpoint assertions to the generated test suite.
