Karate 1.5.0.RC4: cucumber.json Report Not Generated, Only .feature-json.txt Files Created

[medJarray]

Hello, I encountered an issue after upgrading from Karate version 0.9.6 to version 1.5.0.RC4. The problem is that the cucumber.json report is not generated; instead, a .feature-json.txt file is generated.

I am using the following for my Karate project for automated tests:

• Karate library 1.5.0.RC4
• GraalVM 23.0.4
• Java 21
• Cucumber-reporting 5.8.2

Here is a code snippet:

public class DefaultCucumberRunner implements CucumberParallelRunner {

  @Override
  public Results run(CucumberRunnerParameters parameters) {
    var directoryPath = getClassPackagePath(parameters.getRunningClass());
    return Runner.path(getKarateFeaturePaths(directoryPath))
            .outputJunitXml(true)
            .outputCucumberJson(true)
            .tags("~@ignore")
            .parallel(parameters.getThreadCount());
  }

  private static List<String> getKarateFeaturePaths(String directoryPath) {
    var featureFiles = FileUtils.listFiles(
            new File(USER_DIRECTORY + FOLDER_SEPARATOR + directoryPath),
            new String[] {KARATE_FEATURE_EXTENSION},
            true
    );
    return featureFiles.stream()
            .map(File::getPath)
            .toList();
  }
}

public class ReportGenerator {
  private static final String CUCUMBER_HTML_REPORTS_PATH = "target/" + ReportBuilder.BASE_DIRECTORY;
  private final ReportHandler reportHandler;

  /** Clean up report directories. */
  public static void cleanUpReportDirectories(String karateOutputPath) throws IOException {
    FileUtils.deleteDirectory(new File(karateOutputPath));
    FileUtils.deleteDirectory(new File(CUCUMBER_HTML_REPORTS_PATH));
  }

  /** Generate a cucumber HTML report. */
  public void generateReport(String karateOutputPath, boolean isSuccessful) {

    var karateOutputFile = new File(karateOutputPath);

    if (!karateOutputFile.isDirectory()) {
      throw new IllegalArgumentException(
              "Karate report was not correctly created. This might be due to no Karate tests being launched.");
    }
    List<String> jsonPaths = FileUtils.listFiles(karateOutputFile, new String[]{"json"}, true)
            .stream()
            .map(File::getAbsolutePath)
            .toList();

    if (jsonPaths.isEmpty()) {
      throw new IllegalArgumentException("No Karate JSON report files found.");
    }

    var config = new Configuration(new File("target"), "my-project-automatedtest");
    config.setSortingMethod(SortingMethod.ALPHABETICAL);

    var reportBuilder = new ReportBuilder(jsonPaths, config);
    reportBuilder.generateReports();
    var reportDir = new File(config.getReportDirectory(), ReportBuilder.BASE_DIRECTORY);
    reportHandler.handleReport(reportDir, isSuccessful);
  }
}

The issue is that with this version of Karate, even when adding the outputCucumberJson(true) option, I do not find a .json report in the output directory target/karate-reports. I only see .feature-json.txt reports and .html files. Consequently, when generating the report, I encounter an error indicating that the JSON file is not found in the directory.
java.lang.IllegalArgumentException: No Karate JSON report files found.

sounds like a misconfiguration or wrong library still being used. happy to re-open if you follow this process: https://github.com/karatelabs/karate/wiki/How-to-Submit-an-Issue
