### Crear el Código de **FastAPI** { #create-the-fastapi-code }

* Crea un directorio `app` y entra en él.
* Crea un archivo vacío `__init__.py`.
* Crea un archivo `main.py` con:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():

    suite.addTestSuite(ForwardingSetTest.class);
    suite.addTest(
        SetTestSuiteBuilder.using(
                new TestStringSetGenerator() {
                  @Override
                  protected Set<String> create(String[] elements) {
                    return new StandardImplForwardingSet<>(new LinkedHashSet<>(asList(elements)));
                  }
                })

 * These tests verify that the constructor accepts various parameters
 * without throwing exceptions.

            UpgradeContext context = createMockContext();

            // Create a temporary directory with a POM file for the test
            Path tempDir = Files.createTempDirectory("check-test");
            try {
                Path pomFile = tempDir.resolve("pom.xml");
                String pomContent = PomBuilder.create()

## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Using `Jinja2Templates` { #using-jinja2templates }

* Import `Jinja2Templates`.
* Create a `templates` object that you can reuse later.
