Jest中的"it"和"test"有什么区别? [英] What is the difference between 'it' and 'test' in Jest?

问题描述

我的测试组中有两个测试.其中一项测试使用it，另一项使用test.他们似乎在工作上非常相似.它们之间有什么区别?

I have two tests in my test group. One of the tests use it and the other one uses test. Both of them seem to be working very similarly. What is the difference between them?

describe('updateAll', () => {
  it('no force', () => {
    return updateAll(TableName, ["fileName"], {compandId: "test"})
        .then(updatedItems => {
          let undefinedCount = 0;
          for (let item of updatedItems) {
            undefinedCount += item === undefined ? 1 : 0;
          }
          // console.log("result", result);
          expect(undefinedCount).toBe(updatedItems.length);
        })
  });

  test('force update', () => {
    return updateAll(TableName, ["fileName"], {compandId: "test"}, true)
        .then(updatedItems => {
          let undefinedCount = 0;
          for (let item of updatedItems) {
            undefinedCount += item === undefined ? 1 : 0;
          }
          // console.log("result", result);
          expect(undefinedCount).toBe(0);
        })
  });
});

test似乎在 Jest的官方API 中，但是it不是.

It seems that test is in the official API of Jest, but it is not.

推荐答案

it是test 的别名.所以它们是完全一样的.

The Jest docs state it is an alias of test. So they are exactly the same.
