团队应该包含一个技术测试领导或者其他测试项目专家，他们对这个应用软件有熟练的经验，而不是依赖于一个键盘输入水平的测试人员或者测试项目的管理人员。
A tester or a test tool can tell you at a high level that system performance is inadequate, but finding and fixing the underlying causes falls to the developer.
测试人员或者测试工具可以从较高的层面上告诉您系统性能并不充分，但是找到并修复这个潜在问题的任务将落到开发人员身上。
For example, in the test environment, the tester or administrator might enable method-level metrics to show response times within the components of an application (or set of applications) under test.
例如，在测试环境中，测试员或管理员可以启用方法级度量来显示被测试应用程序(或应用程序组)的组件响应时间。
