本文深入解析了测试套件的执行流程，包括setup、beforeEach、afterEach和teardown方法的调用顺序，通过具体代码示例展示了如何在测试模块中组织和执行测试用例。

每一个已注册的根用例：

The setup method of the suite is called, if it exists
For each test within the suite:
- The beforeEach method of the suite is called, if it exists
- The test function is called
- The afterEach method of the suite is called, if it exists
The teardown method of the suite is called, if it exists

So, given the this test module:

define(function (require) {
  var registerSuite = require('intern!object');

  registerSuite({
    setup: function () {
      console.log('outer setup');
    },
    beforeEach: function () {
      console.log('outer beforeEach');
    },
    afterEach: function () {
      console.log('outer afterEach');
    },
    teardown: function () {
      console.log('outer teardown');
    },

    'inner suite': {
      setup: function () {
        console.log('inner setup');
      },
      beforeEach: function () {
        console.log('inner beforeEach');
      },
      afterEach: function () {
        console.log('inner afterEach');
      },
      teardown: function () {
        console.log('inner teardown');
      },

      'test A': function () {
        console.log('inner test A');
      },
      'test B': function () {
        console.log('inner test B');
      }
    },

    'test C': function () {
      console.log('outer test C');
    }
  });
});

…the resulting console output would be in this order:

outer setup
inner setup
outer beforeEach
inner beforeEach
inner test A
inner afterEach
outer afterEach
outer beforeEach
inner beforeEach
inner test B
inner afterEach
outer afterEach
inner teardown
outer beforeEach
outer test C
outer afterEach
outer teardown
