摩卡咖啡测试结构

Question

当我使用命令行运行测试时，所有测试都通过了

describe('my tests', function () {
  context('test a specific thing', function () {
    it('should store a data into the database', function() {
      // store data here and test that it's successful
    });

    it('should fetch that data we stored earlier', function() {
      // fetch that data and test that it's successful
    });
  });
});

但是当我使用Mocha Sidebar extension运行Visual Studio Code的（运行所有测试）时，它说没有存储任何数据

...
it('should fetch that data we stored earlier', function() {
  // fails to fetch and it returns 0 row of data
});
...

这让我开始思考构建考试的方式。看到插件在Run Suite | Debug Suite，Debug Item | Run Item和describe()的上方分别显示context()和it()时，我认为它们应该分别可调试和可运行。

我是否应该通过一系列it()保留数据？

describe('my tests', function () {
  context('test a specific thing', function () {
    it('should store a data into the database', function() {
      // store data here and test that it's successful
    });

    context('since storing worked, only test fetching here', function() {
      before('store data', function () {
        // expect storing to work now
      });
      it('should fetch that data we just stored', function() {
        // fetch that data and test that it's successful
      });
    })

  });
});
