org.testng.TestNGException:
实例化test.SumValidation类时出错：无法使public test.SumValidation()可访问：模块DemoProject未将test包导出给模块org.testng
（后续堆栈跟踪省略）

项目结构 #

• src文件夹
  • files包：Payload.java、ReUsableMethods.java
  • test包：Basics.java、ComplexJsonParse.java、SumValidation.java

依赖配置情况 #

已通过两种方式添加testng、restAssured和hamcrest依赖：

1. Maven依赖（配置pom.xml，也尝试过手动下载添加）
2. 项目库（通过Build Path->Libraries->ModulePath->添加外部JARs）

解决方案 #

1. 解决模块访问权限问题 #

错误核心是模块DemoProject未将test包导出给org.testng，处理方式二选一：

• 若不需要Java模块系统，直接删除项目根目录下的module-info.java文件；
• 若保留模块系统，在module-info.java中添加导出声明：

  module DemoProject {
      exports test to org.testng;
      exports files; // 若其他模块需访问files包也需导出
  }
  

2. 修复pom.xml问题 #

• 删除重复的TestNG依赖，仅保留一个；
• 添加SLF4J日志实现依赖，消除警告，例如添加logback-classic：

  <dependency>
      <groupId>ch.qos.logback</groupId>
      <artifactId>logback-classic</artifactId>
      <version>1.4.8</version>
      <scope>test</scope>
  </dependency>
  

3. 修复代码逻辑错误 #

SumValidation.java中循环里的count["+i+"]应为courses["+i+"]（对应JSON中的数组字段），修正后代码：

for(int i=0;i<count;i++) {
    int price=js.getInt("courses["+i+"].price");
    int copies=js.getInt("courses["+i+"].copies");
    int amount=price*copies;
    System.out.println(amount);
}
