通过docker命令运行cypress时，cypress类型()未定义

Question

在windows 10命令提示符下使用以下docker命令运行cypress测试时，出现以下错误。

docker run -it -v %cd%:/e2e -w /e2e cypress/included:3.4.0

但是，在windows命令提示符下通过npm run cy:test-uattest脚本运行cypress测试时，所有测试都运行成功。知道为什么cy.type()命令在运行docker命令时变得“未定义”吗？

cy.get('input[name="firstInput"]').type(Cypress.env('firstNumber'));

下面是我的Cypress.env.json文件

{
  "numTestsKeptInMemory": 3,
  "firstNumber":"1000"
}

运行docker命令时出错：

CypressError: cy.type() can only accept a String or Number. You passed in: 'undefined'

根据评论，这需要更多的调查。

同时，您可以使用环境变量：

创建一个包含以下内容的文件.env (名称并不重要，只要您在下一步中使用名称即可)：

CYPRESS_numTestsKeptInMemory=3
CYPRESS_firstNumber=1000

使用以下命令在docker中运行测试：

docker run -it -v %cd%:/e2e -w /e2e --env-file .env cypress/included:3.4.0
