### Configurações e testes

Então seria muito fácil fornecer uma configuração diferente durante a execução dos testes sobrescrevendo a dependência de `get_settings`:

```Python hl_lines="9-10  13  21"
{!../../docs_src/settings/app02/test_main.py!}
```

    assertFalse(changed);
  }

  @J2ktIncompatible
  @GwtIncompatible // NullPointerTester
  public void testNullPointerExceptions() {
    NullPointerTester tester = new NullPointerTester();
    tester.testAllPublicStaticMethods(Iterators.class);
  }

  @GwtIncompatible // Only used by @GwtIncompatible code
  private abstract static class EmptyIteratorTester extends IteratorTester<Integer> {

      }
    }
  }

  public void testNullParameters() throws Exception {
    NullPointerTester tester = new NullPointerTester();
    tester.testAllPublicInstanceMethods(makeLocalCache(createCacheBuilder()));
    CacheLoader<Object, Object> loader = identityLoader();
    tester.testAllPublicInstanceMethods(makeLocalCache(createCacheBuilder(), loader));
  }

  public void testSerializationProxyLoading() {

      }
    }
  }

  public void testNullParameters() throws Exception {
    NullPointerTester tester = new NullPointerTester();
    tester.testAllPublicInstanceMethods(makeLocalCache(createCacheBuilder()));
    CacheLoader<Object, Object> loader = identityLoader();
    tester.testAllPublicInstanceMethods(makeLocalCache(createCacheBuilder(), loader));
  }

  public void testSerializationProxyLoading() {

    return this;
  }

  /**
   * Ignore {@code method} in the tests that follow. Returns this object.
   *
   * @since 13.0
   */
  @CanIgnoreReturnValue
  public NullPointerTester ignore(Method method) {

    return this;
  }

    * **WebSockets**
    * uiterst gemakkelijke tests gebaseerd op HTTPX en `pytest`
    * **CORS**
    * **Cookie Sessions**
    * ...en meer.

Only differences from the base Go toolchain defaults are reported.

When testing a package, `//go:debug` lines in the `*_test.go`
files are treated as directives for the test's main package.
In any other context, `//go:debug` lines are ignored by the toolchain;
`go` `vet` reports such lines as misplaced.
