从 0.9.2 更新到 0.9.5 后出现错误 "java.lang.IllegalArgumentException: Illegal group reference"

Question

我的测试套件在使用 0.9.2 版本之前一直运行良好。

我有一个带有 KarateOptions 的测试运行器，用于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",

    })

这个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 并按照最新文档中提到的那样修改了运行程序，

@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);
}

现在当我执行这个套件时，测试正在正确执行。但是在完成所有功能文件的测试执行后，它会为

行抛出错误

Results stats = Runner.parallel(getClass(), 1, karateOutputPath);

有以下 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)

调用跑步者时我错过了什么？如何解决这个问题？

此外，当我尝试为失败的步骤添加异常处理程序时，我收到了以下错误日志，

感谢提示 - 这确实是时间线报告代码中的错误。

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

所以你要等下个版本，不然应该很快就会出RC版，大家可以试试
