问题背景 #

运行Spring Boot的Pact Provider测试时触发NoPactsFoundException，提示找不到要验证的Pact文件。已尝试修改Maven中JUnit和Pact Provider的版本，问题未解决。

排查要点 #

• Provider名称不匹配：错误日志显示Provider为CoursesCatalogue，但测试类@Provider注解的值是toysDetails，两者必须完全一致，否则Pact文件会被忽略。
• Pact文件路径错误：@PactFolder("pactfile")指定的目录是项目根目录下的pactfile文件夹，需确认该目录存在且包含Pact文件。若文件放在src/test/resources下，需调整路径为src/test/resources/pactfile，或直接使用默认目录src/test/resources/pacts。
• Pact文件命名与格式：Pact文件名需遵循消费者名称-提供者名称.json的规范（如toyConsumer-toysDetails.json），且文件必须是合法的JSON格式。
• Maven资源同步：执行mvn clean test前，确认Pact文件已被正确复制到target/test-classes目录中，避免构建资源未同步导致文件缺失。
