剧作家 - 在测试之间共享状态

Question

我正在同时学习 Playwright 和 JavaScript，所以这可能是一个基本问题 - 我想知道人们会如何推荐共享状态 - 在这种情况下为变量 customerId - 在测试之间。

示例：

test.describe.only('Generate a new customer', () => {
  let customerId
  let baseUrl = process.env.SHOP_URL
  
  test('Create new customer', async ({ request }) => {
    const response = await request.post(baseUrl +    `/shopify/v5/customer`, {})
    
    const responseBody = JSON.parse(await response.text())
    expect(response.status()).toBe(200)
    customerId = responseBody.customerId //need to persist customerId to pass into following test

  })

  test('Update customer details', async ({ request }) => {
     const response = await request.post(baseUrl +    `/shopify/v5/customer/update`, {})
      {
        data: {
          customerId: customerId, //customerId is undefined here
          name: "Fred"
        },
      }
    )
    expect(response.status()).toBe(200)
  })

customerId 显然超出了第二次测试的范围。我最终可能会重构这些以使用诸如 Axios 之类的库，因为我正在使用 Playwright 测试来生成数据——我实际上并没有在这里测试 api。与此同时，我只需要 customerId 在后续的 api 调用中保持不变。

Answer 1

这是反模式，测试应该是独立的，尤其是在 playwright 中，默认并行测试运行:

您可以将这两个测试合并为一个测试。

如果你仍然想那样做，我想你可以使用 fixtures 或 hooks 来让它工作，这里有例子：

Answer 2

为了使您的示例工作，您需要运行 serial mode 中的测试，像这样的东西会工作：

test.describe.serial('Generate a new customer', () => {
  let customerId
  let baseUrl = process.env.SHOP_URL
  
  test('Create new customer', async ({ request }) => {
    const response = await request.post(baseUrl +    `/shopify/v5/customer`, {})
    
    const responseBody = JSON.parse(await response.text())
    expect(response.status()).toBe(200)
    customerId = responseBody.customerId //need to persist customerId to pass into following test

  })

  test('Update customer details', async ({ request }) => {
     const response = await request.post(baseUrl +    `/shopify/v5/customer/update`, {})
      {
        data: {
          customerId: customerId, //customerId is undefined here
          name: "Fred"
        },
      }
    )
    expect(response.status()).toBe(200)
  })
});
