jest/max-nested-describe Style
它的作用
此规则强制限制嵌套 describe() 调用的最大深度。
为什么这不好？
describe() 块嵌套得太深会让测试套件难以阅读和理解。
示例
以下模式被视为警告（默认选项为 { "max": 5 } ）：
此规则的错误代码示例：
javascript
describe("foo", () => {
describe("bar", () => {
describe("baz", () => {
describe("qux", () => {
describe("quxx", () => {
describe("too many", () => {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
});
});
});
});
});
describe("foo", function () {
describe("bar", function () {
describe("baz", function () {
describe("qux", function () {
describe("quxx", function () {
describe("too many", function () {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
});
});
});
});
});此规则的正确代码示例：
ts
describe("foo", () => {
describe("bar", () => {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
describe("qux", () => {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
});
describe("foo2", function () {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
describe("foo", function () {
describe("bar", function () {
describe("baz", function () {
describe("qux", function () {
describe("this is the limit", function () {
it("should get something", () => {
expect(getSomething()).toBe("Something");
});
});
});
});
});
});配置
此规则接受一个包含以下属性的配置对象：
max
type: integer
default: 5
允许的 describe 调用最大嵌套深度。
如何使用
To enable this rule using the config file or in the CLI, you can use:
json
{
"plugins": ["jest"],
"rules": {
"jest/max-nested-describe": "error"
}
}ts
import { defineConfig } from "oxlint";
export default defineConfig({
plugins: ["jest"],
rules: {
"jest/max-nested-describe": "error",
},
});bash
oxlint --deny jest/max-nested-describe --jest-plugin版本
此规则添加于 v0.4.4。
