/// note | Technical Details

You could also use `from starlette.responses import HTMLResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

///

### `Response` { #response }

The main `Response` class, all the other responses inherit from it.

        // When errors exist during crawl, the crawler should still complete
        // The actual status behavior depends on the implementation
        // We just verify that the crawl completes with EXIT_OK
        assertTrue("Crawler should complete", result == Constants.EXIT_OK);
    }

    // Test concurrent crawling
    public void test_doCrawl_concurrentWebAndData() {

        } catch (JobProcessingException e) {
            assertEquals("Python Process terminated.", e.getMessage());
            assertNotNull(e.getCause());
            // Check cause message if available, otherwise just verify cause exists
            if (e.getCause().getMessage() != null) {
                assertTrue(e.getCause().getMessage().contains("Process start failed"));
            }
        }
    }

### Using context managers in dependencies with `yield` { #using-context-managers-in-dependencies-with-yield }

/// warning

This is, more or less, an "advanced" idea.

If you are just starting with **FastAPI** you might want to skip it for now.
