This PR extends the IsolateInterpretation class to support a JSON-based rule system similar to the existing MeningoIsolateInterpretation, while maintaining full backward compatibility with the existing hardcoded interpretation logic.

Changes Made

1. Renamed Existing Meningo Rules

  • Renamed StemInterpretationRule.csMeningoStemInterpretationRule.cs
  • Renamed NativeMaterialInterpretationRule.csMeningoNativeMaterialInterpretationRule.cs
  • Updated all references in MeningoIsolateInterpretation.cs

2. Created New Rule System for Haemophilus

  • New rule models: Created StemInterpretationRule.cs and NativeMaterialInterpretationRule.cs that work with Isolate.cs properties instead of MeningoIsolate.cs
  • JSON rule files: Added sample rules in:
    • HaemoStemRules.json - Sample rule for Serotype B detection
    • HaemoNativeMaterialRules.json - Sample rule for molecular typing
    • HaemoTypingTemplates.json - Typing output templates

3. Extended IsolateInterpretation Logic

The IsolateInterpretation.Interpret() method now:

  1. Tries rule-based interpretation first using JSON rules
  2. Falls back gracefully to the existing hardcoded logic when no rule matches
  3. Maintains existing API - no breaking changes to method signatures or return types

4. Added ContainReportLine and NotContainReportLine FluentAssertions Extensions

Added new methods to InterpretationResultAssertion that:

  • ContainReportLine: checks that Report is not null and the collection contains a line matching the expected substring
  • NotContainReportLine: checks that Report is not null and the collection does not contain a line matching the given substring
  • Both support fluent .And chaining

This enables concise test assertions like:

interpretation.Should().BePreliminary()
    .And.ContainReportLine("Das Ergebnis spricht für einen unbekapselten Haemophilus influenzae")
    .And.ContainReportLine("Blut oder Liquor ist nach §7 IfSG meldepflichtig")
    .And.NotContainReportLine("some unexpected line");

These extensions are applied throughout both IsolateInterpretationTests and MeningoIsolateInterpretationTests, replacing all verbose Report.Should().Contain(s => s.Contains("...")) and Report.Should().NotContain(s => s.Contains("...")) patterns with the cleaner fluent API, using .And chaining for consecutive assertions on the same subject.

5. Comprehensive Testing

Added unit tests that verify:

  • Rule-based interpretation works for matching stem rules
  • Rule-based interpretation works for matching native material rules
  • Fallback to original logic when no rules match
  • All existing functionality remains intact

Example Usage

The new rule system automatically detects Haemophilus influenzae Serotype B:

var isolate = new Isolate
{
    SerotypePcr = SerotypePcr.B,
    Agglutination = SerotypeAgg.B,
    BexA = TestResult.Positive,
    Oxidase = TestResult.Negative,
    Sending = new Sending { SamplingLocation = SamplingLocation.Blood }
};

var result = interpretation.Interpret(isolate);
// Uses rule "HaemoStemInterpretation_01" 
// Returns: "Die Ergebnisse sprechen für eine Infektion mit Haemophilus influenzae des Serotyp b (Hib)."

Architecture

The implementation reuses the proven rule engine pattern from MeningoIsolateInterpretation:

  • JSON rules are embedded resources
  • SmartFormat is used for dynamic text generation
  • Rule matching uses property-based conditions
  • Typing information is generated from templates

This approach provides a maintainable and extensible foundation for adding new interpretation rules without code changes.

Fixed the build errors in commit 7045f7f by adding the missing using HaemophilusWeb.Models.Meningo; directive to NativeMaterialInterpretationRule.cs. The MeningoNativeMaterialInterpretationRule and MeningoStemInterpretationRule classes should now be found correctly as they exist in the Domain folder.

@copilot the recent commit introduced custom extension to FluentAssertion like this:

            isolateInterpretation.Should()
                .HaveTyping("Wachstum", "Ja")
                .And.HaveTyping("Agglutination", "negativ")
                .And.HaveTyping("Serotyp-PCR", "negativ")
                .And.HaveTyping("bexA", "negativ")
                .And.HaveTyping("Identifizierung", isolate.Evaluation.ToReportFormat());

Please create a similar extension for this pattern:

 interpretation.Report.Should().NotBeNull();
interpretation.Report.Should().Contain(s => s.Contains("Das Ergebnis spricht für einen unbekapselten Haemophilus influenzae"));
interpretation.Report.Should().Contain(s => s.Contains("Blut oder Liquor ist nach §7 IfSG meldepflichtig"));
interpretation.Report.Should().Contain(s =>
   s.Contains("Meldekategorie dieses Befundes: Haemophilus influenzae, unbekapselt."));

E.g. it should be: interpretation.Should().ContainReportLine("Das Ergebnis spricht für einen unbekapselten Haemophilus influenzae")

The new extension should

  • Check for interpretation.Report not being null
  • the collection contains a line matching the argument

Also chain multiple calls on interpretation.Should().ContainReportLine with FluentAssertions .And

@copilot the recent commit introduced custom extension to FluentAssertion like this:

...

Added the ContainReportLine extension method to InterpretationResultAssertion in commit 7e9a26b. It checks that Report is not null and that the collection contains a line matching the argument. Updated all test assertions in IsolateInterpretationTests.cs to use the new fluent API with .And chaining, e.g.:

interpretation.Should().BePreliminary()
    .And.ContainReportLine("Das Ergebnis spricht für einen unbekapselten Haemophilus influenzae")
    .And.ContainReportLine("Blut oder Liquor ist nach §7 IfSG meldepflichtig")
    .And.ContainReportLine("Meldekategorie dieses Befundes: Haemophilus influenzae, unbekapselt.");

Applied the same ContainReportLine/NotContainReportLine pattern to MeningoIsolateInterpretationTests.cs (88 occurrences), with .And chaining for consecutive assertions on the same subject. Also added NotContainReportLine to InterpretationResultAssertion for the NotContain patterns present in the meningo tests. Committed in a3ca192 and 1acd241.

…xtensions

Replace verbose FluentAssertions patterns with cleaner extension methods:
- Replace Result.Report.Should().Contain(s => s.Contains("...")) with
  Result.Should().ContainReportLine("...")
- Replace Result.Report.Should().NotContain(s => s.Contains("...")) with
  Result.Should().NotContainReportLine("...")
- Consolidate consecutive calls on the same Result using .And chaining
- Handle multi-line lambda patterns (string on next line, ternary expressions)
- Preserve Report.Should().BeEmpty() patterns unchanged
