`33.5.0-android`. For more about depending on Guava, see
[using Guava in your build].

To add a dependency on Guava using Maven, use the following:

```xml
<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>33.5.0-jre</version>
  <!-- or, for Android: -->
  <version>33.5.0-android</version>
</dependency>
```

To add a dependency using Gradle:

```gradle
dependencies {

          parentBuilder) {
    List<TestSuite> derived = super.createDerivedSuites(parentBuilder);
    // TODO(cpovirk): consider using this approach (derived suites instead of extension) in
    // ListTestSuiteBuilder, etc.?
    derived.add(
        MapTestSuiteBuilder.using(new MapGenerator<K, V>(parentBuilder.getSubjectGenerator()))
            .withFeatures(parentBuilder.getFeatures())

Nevertheless, you can still do it in **FastAPI**, using one of the internal tools from Starlette.

And the docs would still work, although not adding any documentation telling that the parameter should contain a path.

### Path convertor { #path-convertor }

Using an option directly from Starlette you can declare a *path parameter* containing a *path* using a URL like:

```
/files/{file_path:path}
```

            ListTestSuiteBuilder.using(new LongsAsListHeadSubListGenerator())
                .named("Longs.asList, head subList"),
            ListTestSuiteBuilder.using(new LongsAsListTailSubListGenerator())
                .named("Longs.asList, tail subList"),
            ListTestSuiteBuilder.using(new LongsAsListMiddleSubListGenerator())

            ListTestSuiteBuilder.using(new ShortsAsListGenerator()).named("Shorts.asList"),
            ListTestSuiteBuilder.using(new ShortsAsListHeadSubListGenerator())
                .named("Shorts.asList, head subList"),
            ListTestSuiteBuilder.using(new ShortsAsListTailSubListGenerator())
                .named("Shorts.asList, tail subList"),
            ListTestSuiteBuilder.using(new ShortsAsListMiddleSubListGenerator())

            ListTestSuiteBuilder.using(new CharsAsListGenerator()).named("Chars.asList"),
            ListTestSuiteBuilder.using(new CharsAsListHeadSubListGenerator())
                .named("Chars.asList, head subList"),
            ListTestSuiteBuilder.using(new CharsAsListTailSubListGenerator())
                .named("Chars.asList, tail subList"),
            ListTestSuiteBuilder.using(new CharsAsListMiddleSubListGenerator())

            ListTestSuiteBuilder.using(new ShortsAsListGenerator()).named("Shorts.asList"),
            ListTestSuiteBuilder.using(new ShortsAsListHeadSubListGenerator())
                .named("Shorts.asList, head subList"),
            ListTestSuiteBuilder.using(new ShortsAsListTailSubListGenerator())
                .named("Shorts.asList, tail subList"),

* Processing data:
    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process the file in the background.

## Using `BackgroundTasks` { #using-backgroundtasks }

First, import `BackgroundTasks` and define a parameter in your *path operation function* with a type declaration of `BackgroundTasks`:
