环境：量角器，茉莉，打字稿

我有几个具有不同设置和相同断言的测试。it在 a中的每个中输入不同的步骤describe并expect在 afterEach 块中输入不同的步骤是一种好习惯吗？

示例：表单包含phoneNumberField和一个submitBtn;

测试 1：输入太短的数字phoneNumberField=> 期望submitBtn被禁用。

phoneNumberField测试 2：在=> Expect to be disabled 中输入文本submitBtn示例代码：

describe('Invalid phone number => submitBtn disabled', () => {

    afterEach(() => {
        expect(submitBtn.isEnabled()).toBeFalsy();
    });

    it('Too short number input', () => {
        phoneNumberField.sendKeys('012');
    });

    it('Text input', () => {
        phoneNumberField.sendKeys('asdf');
    });
});

老实说，我很惊讶它以这种方式工作......我想说“不，这不是一个好习惯......”但在玩了几分钟后，我没有发现这样做有任何缺点它。

但我仍然不会这样做，因为如果你放在expect()块it()中，很容易看到你的测试中的逻辑顺序（例如打开页面->期望 smtng；单击按钮->期望 smtng；等）

但是你可以实现它，使用它一段时间，看看它是否适合你自己

PS只是为了形象化为什么我认为这不是一个可怕的想法，因为它看起来可能是：拥有以下代码

beforeAll(async () => {expect(true).toBe(false)});

it("1", async () => {
});

it("2", async () => {
});

it("3", async () => {
});

将产生以下输出

可以看出，报告正在正常打印，其中每个失败都显示为单独的it()测试用例失败
