看起来像是版本兼容性问题。使用最新版本的 qaf 3.1.0-RC2 和 testng 7.4.0。

更新版本将修复上述错误，但您仍会看到与步骤相关的问题。原因如下：

@QAFTestStep(description="click on Google Search button") //missing argument placeholder 
   public void clickOnGoogleSearchButton(List<String> s) {
      System.out.printf("List: %s\n", s);
   }
           
@QAFTestStep(description="search result page should generate")//missing argument placeholder
   public void searcgResultsShouldPopulate(List<String> s) {
      System.out.printf("List: %s\n", s);
   }

如果您的步骤（方法）有参数，步骤描述需要有参数占位符，并且这些参数需要在调用步骤的地方传递。请看下面的例子：

@QAFTestStep(description="click on Google Search button")
   public void clickOnGoogleSearchButton() {
      System.out.printf("clickOnGoogleSearchButton");
   }
           
@QAFTestStep(description="search result page should generate {results}")
   public void searcgResultsShouldPopulate(List<String> s) {
      System.out.printf("List: %s\n", s);
   }
