Avoid ignoring exceptions in automated tests

[basiliskus]

Avoid ignoring exceptions in automated tests

• Bubble up exceptions, add context, and let automated test fail
• Throw exception if failed to find matching input or output
• Refactored to simplify logic in matchFiles
• Added custom exception HapiHL7FileMatcherException

Issue

#1536

Checklist

• I have added tests to cover my changes
• I have added logging where useful (with appropriate log level)
• I have added JavaDocs where required
• I have updated the documentation accordingly

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible bug	Add null checks to prevent NullPointerException Add null checks for mshSegment and message objects before accessing their properties to avoid potential NullPointerException. rs-e2e/src/main/java/gov/hhs/cdc/trustedintermediary/rse2e/external/hapi/HapiHL7FileMatcher.java [83-85] Message message = parser.parse(content); +if (message == null) throw new HL7Exception("Parsed message is null"); MSH mshSegment = (MSH) message.get("MSH"); +if (mshSegment == null) throw new HL7Exception("MSH segment is missing"); String msh10 = mshSegment.getMessageControlID().getValue(); Suggestion importance[1-10]: 8 Why: Adding null checks before accessing properties of potentially null objects is a critical safety measure to prevent runtime errors like NullPointerException. This suggestion significantly enhances the reliability and stability of the code.	8
Best practice	Add resource cleanup to prevent leaks in the test case Ensure that the test case "should throw IllegalArgumentException when MSH-10 is empty" includes a cleanup step to close the InputStream and other resources to prevent resource leaks. rs-e2e/src/test/groovy/gov/hhs/cdc/trustedintermediary/rse2e/external/hapi/HapiHL7FileMatcherTest.groovy [80-81] def inputStream = new ByteArrayInputStream(mshSegment.bytes) def hl7FileStream = new HL7FileStream("file1", inputStream) +// Cleanup resources after test execution +inputStream.close() Suggestion importance[1-10]: 7 Why: Proper resource management is crucial in tests to prevent resource leaks. The suggestion to close the InputStream after the test is a good practice, enhancing the robustness of the test case.	7
Enhancement	Separate exception handling for HL7Exception and IOException for clearer error management Refactor the mapMessageByControlId method to handle IOException separately from HL7Exception to provide more specific error handling and logging for different types of exceptions. rs-e2e/src/main/java/gov/hhs/cdc/trustedintermediary/rse2e/external/hapi/HapiHL7FileMatcher.java [91-94] } catch (HL7Exception e) { throw new HL7Exception( String.format("Failed to parse HL7 message from file: %s", fileName), e); +} catch (IOException e) { + throw new IOException( + String.format("Failed to read file: %s", fileName), + e); } Suggestion importance[1-10]: 6 Why: Separating the exception handling for HL7Exception and IOException can provide clearer and more specific error management. This suggestion improves the code's maintainability and readability by handling different types of exceptions distinctly.	6
Performance	Optimize reading from input stream for better performance and memory management Consider using a more efficient method to read the input stream into a string, such as using a buffered reader, to improve performance and reduce memory usage. rs-e2e/src/main/java/gov/hhs/cdc/trustedintermediary/rse2e/external/hapi/HapiHL7FileMatcher.java [82] -String content = new String(inputStream.readAllBytes(), StandardCharsets.UTF_8); +String content; +try (BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8))) { + content = reader.lines().collect(Collectors.joining("\n")); +} Suggestion importance[1-10]: 5 Why: Using a BufferedReader to read the input stream can improve performance and reduce memory usage. This suggestion is beneficial for optimizing resource utilization, especially in scenarios involving large data streams.	5

Maybe add context on why we want this instead of logging in the description but besides that me likey
