Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).

## Program and Process { #program-and-process }

We will talk a lot about the running "**process**", so it's useful to have clarity about what it means, and what's the difference with the word "**program**".

        queryFieldConfig.highlightedFields = null;

        // When highlightedFields is null, the method should handle it gracefully
        // or throw an exception. Test the actual behavior.
        queryFieldConfig.highlightedFields(stream -> {
            // If it doesn't throw NPE, it should provide an empty stream
            assertEquals(0, stream.count());
        });
    }

        cmdList.add("test");
        cmdList.add("command");

        File propFile = new File(tempDir, "test.properties");

        // Mock ComponentUtil.getSystemProperties() to return actual system properties
        Properties systemProps = System.getProperties();

        // Set a system property
        System.setProperty("test.prop", "test.value");

        SMBUtil.writeInt8(1000000, buffer, 20); // Total allocation units
        SMBUtil.writeInt8(500000, buffer, 28); // Caller available units
        SMBUtil.writeInt8(600000, buffer, 36); // Actual available units
        SMBUtil.writeInt4(512, buffer, 44); // Sectors per unit
        SMBUtil.writeInt4(4096, buffer, 48); // Bytes per sector

        int result = response.readBytesWireFormat(buffer, bufferIndex);

        int wireCommentOffset = actualCommentOffset + converterValue;
        SMBUtil.writeInt4(wireCommentOffset, buffer, bufferIndex);
        bufferIndex += 4;

        // Write comment at actual offset
        byte[] commentBytes = comment.getBytes(StandardCharsets.US_ASCII);
        System.arraycopy(commentBytes, 0, buffer, actualCommentOffset, commentBytes.length);

	handlerName := getHandlerName(f, "objectAPIHandlers")

	var handler http.HandlerFunc = func(w http.ResponseWriter, r *http.Request) {
		w = &trackingResponseWriter{ResponseWriter: w}

		// Wrap the actual handler with the appropriate tracing middleware.
		var tracedHandler http.HandlerFunc
		if handlerFlags.has(traceHdrsS3HFlag) {
			tracedHandler = httpTraceHdrs(f)
		} else {
			tracedHandler = httpTraceAll(f)
		}
