describe/it 语法

🌐 describe/it syntax

运行测试也可以使用 describe 来声明一个测试套件，使用 it 来声明一个测试。测试套件用于组织和分组相关的测试。it 是 test() 的简写。

🌐 Running tests can also be done using describe to declare a suite and it to declare a test. A suite is used to organize and group related tests together. it is a shorthand for test().

describe('A thing', () => {
  it('should work', () => {
    assert.strictEqual(1, 1);
  });

  it('should be ok', () => {
    assert.strictEqual(2, 2);
  });

  describe('a nested thing', () => {
    it('should work', () => {
      assert.strictEqual(3, 3);
    });
  });
}); 拷贝

describe 和 it 是从 node:test 模块中导入的。

import { describe, it } from 'node:test';const { describe, it } = require('node:test');拷贝
