【问题描述】：

我正在尝试查看页面上显示的数字是否大于 0。 如果是我需要通过测试 如果不是，我需要测试失败

目前为止的代码

test("searching for 0100t should show a out of pocket expense", async()=>
    let surgicalCentersCost = await page.$$eval('.chart-inner-label-cost >> nth=0')
    let hospitalOutpatientCost = await page.$$eval('.chart-inner-label-cost >> nth=1')
    surgicalCentersCost = surgicalCentersCost.replace('$','');
    hospitalOutpatientCost = hospitalOutpatientCost.replace('$','');
    surgicalCentersCost = parseInt(surgicalCentersCost);
    hospitalOutpatientCost = parseInt(hospitalOutpatientCost)
    expect(surgicalCentersCost) // <-- what happens here?

  )

基本上我喜欢一个 if 语句，它查看 surgicalCentersCost 和 hospitalOutpatientCost 并且如果两者都是 > 0 信号测试通过，否则信号测试失败

我知道我们可以在 cypress 中做这样的事情，但我工作的公司坚持要剧作家。这样的事情可能吗？

【问题讨论】：

.chart-inner-label-cost >> nth=0 解析为什么？您可能需要将代码替换为 let surgicalCentersCost = await page.locator('.chart-inner-label-cost >> nth=0').innerText() 之类的代码，如果没有看到页面就很难分辨。至于你需要的预期条件expect(surgicalCentersCost > 0).toBeTruthy(); expect(hospitalOutpatientCost > 0).toBeTruthy();

【参考方案1】：

我即将对此进行测试，但看起来正则表达式是要走的路。观察最后两行。

test("searching for 0100t should show a out of pocket expense", async()=>
    let surgicalCentersCost = await page.$$eval('.chart-inner-label-cost >> nth=0')
    let hospitalOutpatientCost = await page.$$eval('.chart-inner-label-cost >> nth=1')
    surgicalCentersCost = surgicalCentersCost.replace('$','');
    hospitalOutpatientCost = hospitalOutpatientCost.replace('$','');
    surgicalCentersCost = surgicalCentersCost.replace(',','');
    hospitalOutpatientCost = hospitalOutpatientCost.replace(',','');
    surgicalCentersCost = parseInt(surgicalCentersCost);
    hospitalOutpatientCost = parseInt(hospitalOutpatientCost)
    await expect(surgicalCentersCost).toHaveValue(/^[1-9][0-9]*$/)
    await expect(hospitalOutpatientCost).toHaveValue(/^[1-9][0-9]*$/)

  )
