jest/no-conditional-in-test Pedantic
它的作用
禁止在测试中使用条件语句。
为什么这不好？
测试中的条件语句会让测试更难阅读和理解。 最好每个测试函数只包含一个测试用例。
示例
以下是此规则的错误代码示例：
js
it("foo", () => {
if (true) {
doTheThing();
}
});
it("bar", () => {
switch (mode) {
case "none":
generateNone();
case "single":
generateOne();
case "multiple":
generateMany();
}
expect(fixtures.length).toBeGreaterThan(-1);
});
it("baz", async () => {
const promiseValue = () => {
return something instanceof Promise ? something : Promise.resolve(something);
};
await expect(promiseValue()).resolves.toBe(1);
});以下是此规则的正确代码示例：
js
describe("my tests", () => {
if (true) {
it("foo", () => {
doTheThing();
});
}
});
beforeEach(() => {
switch (mode) {
case "none":
generateNone();
case "single":
generateOne();
case "multiple":
generateMany();
}
});
it("bar", () => {
expect(fixtures.length).toBeGreaterThan(-1);
});
const promiseValue = (something) => {
return something instanceof Promise ? something : Promise.resolve(something);
};
it("baz", async () => {
await expect(promiseValue()).resolves.toBe(1);
});如何使用
To enable this rule using the config file or in the CLI, you can use:
json
{
"plugins": ["jest"],
"rules": {
"jest/no-conditional-in-test": "error"
}
}ts
import { defineConfig } from "oxlint";
export default defineConfig({
plugins: ["jest"],
rules: {
"jest/no-conditional-in-test": "error",
},
});bash
oxlint --deny jest/no-conditional-in-test --jest-plugin版本
此规则添加于 v0.8.0。
