在AfterEach街区中提出断言是一个好习惯吗?

Question

环境：量角，茉莉，打字稿

我有几个具有不同设置和相同断言的测试。在describe中的每个it中输入不同的步骤是一个好习惯，在Aftereach块中的expect断言？

示例：表格包含phoneNumberField和submitBtn;

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

测试2：输入文本中的phoneNumberField =>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');
    });
});

Answer 1

老实说，我很惊讶它以这种方式起作用...我要说的是"不，这不是一个好练习……"但是我没有发现任何事情的缺点用它玩了几分钟后。

但我仍然不会这样做，因为如果您将expect()放在it()块中，则很容易在测试中看到逻辑的顺序(例如，打开Page->期望SMTNG;单击按钮 ->期待SMTNG; etc et et smtng; etc et et smtng；(

，但是您可以实现它，使用一点，看看它是否对您自己有效

P.S。只是为了想象为什么我认为这似乎不是一个可怕的想法：在代码下面

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，其中每个故障被视为个体，是it()测试用例的故障
