describe/it 语法
运行测试也可以使用 describe
来声明套件和 it
来声明测试。
套件用于将相关测试组织和分组在一起。
it
是 test
的别名,除了没有通过测试上下文,因为嵌套是使用套件完成的。
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);
});
});
});
describe
和 it
是从 node:test
模块导入的。
import { describe, it } from 'node:test';
const { describe, it } = require('node:test');
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 an alias for test
, except there is no test context passed,
since nesting is done using suites.
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);
});
});
});
describe
and it
are imported from the node:test
module.
import { describe, it } from 'node:test';
const { describe, it } = require('node:test');
