Question

环境：量角器，茉莉花，打字稿

我有几个测试具有不同的设置和相同的断言。好的做法是在afterEach块的it内的每个describe和expect断言中分别输入不同的步骤吗？

示例：表单包含phoneNumberField和submitBtn;

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

测试2：在phoneNumberField中输入文本=>期望submitBtn被禁用示例代码：

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，我很惊讶它能如此工作……我要说的是“不，这不是一个好习惯……”，但是在玩了一段时间之后，我没有发现这样做的任何缺点。几分钟。

但是我仍然不会这样做，因为如果将expect()放在it()块中，很容易看到测试中逻辑的顺序（例如，打开页面->期望smtng；点击按钮->期待smtng；等等）

但是您可以实施它，使用一段时间，看看它是否对您自己很好

P.S。只是想像一下为什么我认为这不是一个可怕的主意，因为它看起来像是：有下面的代码

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，报告正常打印，其中每个失败都作为一个单独的it()测试用例显示

将断言放在afterEach块中是一种好习惯吗？
