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

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]](https://github.com/CDCgov/trusted-intermediary/pull/1543/files#diff-77eec62982c47378e3346e74691927296cce47bff6f9e8b8df519894c5ecdf06R83-R85) ```diff 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]](https://github.com/CDCgov/trusted-intermediary/pull/1543/files#diff-64474d59c35e013442f37e1dec8f4c1890f07e9eb221bdfa7f56b652cac5c2c6R80-R81) ```diff 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]](https://github.com/CDCgov/trusted-intermediary/pull/1543/files#diff-77eec62982c47378e3346e74691927296cce47bff6f9e8b8df519894c5ecdf06R91-R94) ```diff } 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]](https://github.com/CDCgov/trusted-intermediary/pull/1543/files#diff-77eec62982c47378e3346e74691927296cce47bff6f9e8b8df519894c5ecdf06R82-R82) ```diff -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
