...and then Swagger UI won't show the syntax highlighting anymore:

## Change the Theme { #change-the-theme }

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

        FessUserNotFoundException exception1 = new FessUserNotFoundException("user1");
        FessUserNotFoundException exception2 = new FessUserNotFoundException("user2");

        // Both instances should be of the same class
        assertEquals(exception1.getClass(), exception2.getClass());
    }

    public void test_stackTrace() {
        // Test that the exception has a proper stack trace

        // When & Then - verify consistency across multiple calls
        for (int i = 0; i < 10; i++) {
            assertTrue(consistentRequest.isSigningEnforced(), "Implementation should consistently return the same value");
        }
    }

    @Test
    @DisplayName("Test different implementations can have different behaviors")
    void testDifferentImplementations() {
        // Given

     * @see org.apache.maven.api.Session#isVersionSnapshot(String)
     */
    boolean isSnapshot();

    /**
     * {@return coordinates with the same identifiers as this artifact}.
     * This is a shortcut for {@code session.createArtifactCoordinates(artifact)}.
     *
     * @see org.apache.maven.api.Session#createArtifactCoordinates(Artifact)
     */
    @Nonnull

    *   Allow LinearOperator to broadcast.
    *   SavedModelBuilder will now deduplicate asset names that point to files
        with the same basename and the same contents. Note that this may result
        in new asset files included in SavedModels in cases where assets with
        the same name but different contents were previously overwriting each
        other.

    worked everywhere that I know of except for one place: when running the GWT
    util.concurrent tests under Guava.

    The problem is that GWT responds poorly to two .gwt.xml files in the same
    Java package; see
    https://groups.google.com/g/google-web-toolkit-contributors/c/CqYH59Dt_rQ/m/uVGW1QdUsXUJ
    for details.

    The summary is that it ignores one file in favor of the other.

You could also use `from starlette.staticfiles import StaticFiles`.

**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.
