# swagger-coverage-py

#### This project is the adapter that allows using [swagger-coverage](https://github.com/viclovsky/swagger-coverage) tool in Python projects (PyTest+Requests).

## Original description summary:

> Swagger-coverage gives a full picture about coverage of API tests (regression) based on OAS 2 (Swagger). By saying coverage we mean not a broad theme functionality, but presence (or absence) of calls defined by API methods, parameters, return codes or other conditions which corresponds specification of API.

Some more info about the project you can also
find [HERE](https://viclovsky.github.io/%D0%B0%D0%B2%D1%82%D0%BE%D1%82%D0%B5%D1%81%D1%82%D1%8B%20%D0%BD%D0%B0%20api/2020/01/16/swagger-coverage)

# How to use:

All required steps are listed below. Additionally, you can find a working example
here: [allure-results-sample](https://github.com/JamalZeynalov/allure-results-sample).

### 0. Resolve dependencies:

* python 3.6+
* java JDK 11+ (with JAVA_HOME environment variable set)
* Enable Long Paths (Windows only). Check the
  guide [HERE](https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation#enable-long-paths-in-windows-10-version-1607-and-later)

### 1. Install `swagger-coverage-py` as a project requirement.

```shell
pip install swagger-coverage
```

### 2. Add environment variables (Optionally):
```dotenv
API_DOCS_TYPE="swagger"  # Note: "openapi" is default type of API docs
API_DOCS_VERSION="2.0"  # Note: "3.0.0" is default version of API docs
API_DOCS_FORMAT="yaml"  # Note: "json" is default format of API docs and output files
API_COVERAGE_REPORTS_DISABLED=True  # Skip requests recording. No files will be saved to 'swagger-coverage-output' dir 

```

### 3. Add the session-scoped fixture

```python
import pytest
from swagger_coverage_py.reporter import CoverageReporter
from requests.auth import HTTPBasicAuth


@pytest.fixture(scope="session", autouse=True)
def setup_swagger_coverage():
    reporter = CoverageReporter(api_name="my-project", host="http://my-project.com")
    reporter.cleanup_input_files()
    reporter.setup("/api/v1/resources/my_project/doc/swagger.json", auth=HTTPBasicAuth("username", "password"))

    yield
    reporter.generate_report()
```

#### If you have 2 and more projects, then just add more reporters:

```python
import pytest
from swagger_coverage_py.reporter import CoverageReporter
from requests.auth import HTTPBasicAuth


@pytest.fixture(scope="session", autouse=True)
def setup_swagger_coverage():
    reporter = CoverageReporter(api_name="petstore", host="https://petstore.swagger.io")
    reporter.cleanup_input_files()
    reporter.setup(path_to_swagger_json="/v2/swagger.json")

    reporter2 = CoverageReporter(api_name="my-project", host="http://my-project.com")
    reporter2.cleanup_input_files()
    reporter2.setup(path_to_swagger_json="/api/v1/swagger.json", auth=HTTPBasicAuth("username", "password"))

    yield
    reporter.generate_report()
    reporter2.generate_report()
```

#### YAML format is also supported:

```python
import pytest
from swagger_coverage_py.reporter import CoverageReporter


@pytest.fixture(scope="session", autouse=True)
def setup_swagger_coverage():
    reporter = CoverageReporter(api_name="petstore", host="https://petstore.swagger.io")
    reporter.cleanup_input_files()
    reporter.setup("/v2/swagger.yaml")

    yield
    reporter.generate_report()
```

> #### Steps and Parameters:
> `api_name` - Define the name of the API. This name will be used to find a configuration file.<br>
> &nbsp;&nbsp;&nbsp;&nbsp; For APIs in this example the files must
> have names `swagger-coverage-config-petstore.json` and `swagger-coverage-config-my-project.json`.<br>
>
> `host` - The host of the API.
> It will be used to download a swagger.json file and to identify the CoverageListener output directory for each API.
>
> `cleanup_input_files()` - THis step deletes all files in the CoverageListener output directory (according to the target host)
>
> `path_to_swagger_json` - A second part of the HTTP link to your OpenApi/Swagger documentation in JSON format<br>
> &nbsp;&nbsp;&nbsp;&nbsp; Adapted `swagger-<api_name>.json` file will be created in your project root.<br>
> &nbsp;&nbsp;&nbsp;&nbsp; The "Swagger 2.0" format is completely compatible with this tool.<br>
> &nbsp;&nbsp;&nbsp;&nbsp; The "OpenAPI 3.0.2" format is partly compatible.
> "Tags coverage summary" calculation is not supported.<br>
>
> `auth` - An authentication parameter for "requests" lib. Skip it if your API doesn't require authentication.

### 4. Create and place `swagger-coverage-config-<api_name>.json` file(s) to your project:

```json
{
    "rules": {
        "status": {
            "enable": true,
            "ignore": [
                "500"
            ],
            "filter": []
        },
        "only-declared-status": {
            "enable": false
        },
        "exclude-deprecated": {
            "enable": true
        }
    },
    "writers": {
        "html": {
            "locale": "en",
            "filename": "swagger-coverage-report-petstore.html"
        }
    }
}
```

> ### If you have more than 1 API then this config MUST:
> #### 1. Be created for each microservice which you track using `CoverageListener`.
> Otherwise, the default behavior will be applied, and your report will be saved as `swagger-coverage-report.html` which may cause override in case you have multiple APIs
> #### 2. Contain `writers` section with filename in the format: `swagger-coverage-report-<api_name>.html`
> #### 3. Be placed in the root of your project

More examples of configuration options you can find in
the [Configuration options](https://github.com/JamalZeynalov/swagger-coverage#configuration-options) section of the
documentation.

### 5. Trace all your API calls with CoverageListener:

```python
from requests import Response
from requests.auth import HTTPBasicAuth
from swagger_coverage_py.listener import CoverageListener

response: Response = CoverageListener(
    method="get",
    base_url="https://petstore.swagger.io",
    raw_path="/v2/store/order/{orderId}",
    uri_params={"orderId": 1},
    auth=HTTPBasicAuth("username", "password"),
    params={"type": "active"},
).response
```

> #### Note: "auth" and "params" arguments are default for "requests" lib and are not required. <br>You can use any other **kwargs that are applicable for Requests library.

### 6. Run your tests and open created `swagger-coverage-report-<api_name>.html` report(s) in your browser.

Important remarks:

1. Virtual environments are supported. Make sure your virtual environment directory has name `venv`.
2. To create report you have to run your test from the project root. Check that workind directory of your runner is
   not `"<root>/test"`

# How it works:

1. The fixture `setup_swagger_coverage` setups required artifacts
2. During test execution the CoverageListener saves all requests as JSON files in swagger format to a subdirectory named
   as a called host. (e.g. `swagger-coverage-output/petstore.swagger.io/`).
3. After all tests execution a `CoverageReporter().generate_report()` creates and saves new report(s) into your project
   root.
