Package io.karatelabs.output

Class CucumberJsonReportListener

java.lang.Object

io.karatelabs.output.CucumberJsonReportListener

All Implemented Interfaces:

ResultListener

public class CucumberJsonReportListener
extends Object
implements ResultListener

A ResultListener that generates Cucumber JSON reports asynchronously.

This listener writes per-feature Cucumber JSON files as features complete using a single-thread executor. Each feature produces a separate JSON file named {packageQualifiedName}.json. This approach:

• Does not block test execution during report generation
• Makes partial results available as tests complete
• Compatible with third-party tools (Allure, ReportPortal, etc.)
