QAF中使用@dependsOnMethods出现嵌套异常错误求助

在以下测试场景中使用@dependsOnMethods注解时会触发嵌套异常，不使用该注解则所有场景可正常运行：

• 测试版本：qaf.version 3.2.0（Selenium 3.141.59）、4.0.0-RC2（Selenium 4.11.0）

测试代码示例 #

@test0 @priority:1 @dependsOnMethods:[]
Scenario Outline: Scenario Test 1
  Given Test step
  Then I comment "<test_data>"
Examples: 
  | test_data   |
  | test data 1 |
  | test data 2 |

@test @priority:2 @dependsOnMethods:["Scenario Test 1"]
Scenario: Scenario Test 2
  Given Test step

问题原因与解决方案 #

核心原因 #

Scenario Outline会根据Examples中的数据生成多个实际运行的测试方法，原始的Scenario Outline名称不会作为有效方法名存在，导致@dependsOnMethods无法匹配到对应方法，触发TestNG依赖异常。

解决方案 #

改用@dependsOnGroups注解实现依赖，给Scenario Outline指定一个分组，让依赖场景关联该分组：

@test0 @priority:1 @groups:["scenario1_group"] @dependsOnMethods:[]
Scenario Outline: Scenario Test 1
  Given Test step
  Then I comment "<test_data>"
Examples: 
  | test_data   |
  | test data 1 |
  | test data 2 |

@test @priority:2 @dependsOnGroups:["scenario1_group"]
Scenario: Scenario Test 2
  Given Test step

这种方式下，Scenario Outline生成的所有实例化测试方法都会继承该分组，依赖场景会等待分组内所有方法执行完成后再运行，是适配Scenario Outline依赖的可靠方式。
