【问题描述】：

在使用 0.9.2 版本之前，我的测试套件运行良好。

我有一个测试运行器，其中包含 KarateOptions 来指定要执行的功能文件

@KarateOptions(tags = "~@ignore",
    features = 
            "src/test/java/com/pro/api/tests/features/beforesuitescenarios/feature1.feature",
             "src/test/java/com/pro/api/tests/features/customerscenarios/feature2.feature",
            "src/test/java/com/pro/api/tests/features/servicerequestscenarios/feature3.feature",
            "src/test/java/com/pro/api/tests/features/invoicescenarios/feature4.feature",

    )

为此的测试运行器使用的是黄瓜运行器，

  @Test
public void testAllFeatures() throws Exception  
    String karateOutputPath = "target/surefire-reports";
    KarateStats stats = CucumberRunner.parallel(getClass(), 1, karateOutputPath);
    generateReport(karateOutputPath);
    assertTrue("There are scenario failures", stats.getFailCount() == 0);

我尝试将框架升级到 0.9.5 并修改了运行器，就像它在最新文档中提到的那样，

@Test
public void testAllFeatures() throws Exception 

    String karateOutputPath = "target/surefire-reports";
    Results stats = Runner.parallel(getClass(), 1, karateOutputPath);
    generateReport(karateOutputPath);
    assertTrue("There are scenario failures", stats.getFailCount() == 0);

现在，当我执行此套件时，测试正在正确执行。但是在所有功能文件的测试执行完成后，它正在为该行抛出错误

结果统计 = Runner.parallel(getClass(), 1, karateOutputPath);

出现以下 IllegalArgumentException，

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1,295.291 s <<< 
FAILURE! - in com.pro.api.tests.features.TestRunner

 <<< ERROR!
java.lang.IllegalArgumentException: Illegal group reference
at com.pro.api.tests.features.TestRunner.testAllFeatures(TestRunner.java:55)

打电话给跑步者时我错过了什么？如何解决这个问题？

当我尝试为失败的步骤添加异常处理程序时，我得到以下错误日志，

【参考方案1】：

感谢您的提示 - 这确实是时间线报告代码中的一个错误。

问题参考：https://github.com/intuit/karate/issues/1085

所以你需要等待下一个版本，或者应该很快会有一个RC版本，这样你就可以试用了。

非常感谢，急切等待修复:)
