通过docker命令运行cypress时，cypress type（）变得不确定 [英] While running cypress via docker command, cypress type() getting undefined

问题描述

在Windows 10命令提示符下使用以下docker命令运行cypress测试时，发生以下错误。

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

但是在通过 npm运行cypress测试时，从Windows命令中运行cy：test-uattest 脚本，提示所有测试成功运行。知道为什么运行docker命令时 cy.type（）命令会变为'undefined'。

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（）仅接受字符串或数字。您传入了：Object.cypressErr（https://someurl.net/__cypress/runner/cypress_runner.js:84963:11）中的'undefined'

解决方案

根据评论，这需要更多的调查。 / p>

同时，您可以使用环境变量：

创建文件 .env （名称不重要，只要您在下一步中使用该名称）就具有以下内容：

  CYPRESS_numTestsKeptInMemory = 3 
 CYPRESS_firstNumber = 1000 
  

在docker中使用以下命令运行测试：

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

While running the cypress test using below docker command from windows 10 command prompt, the below error occurs.

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

But while running the cypress test by npm run cy:test-uattest script from windows command prompt all the test run successfully. Any idea why the cy.type() command becomes 'undefined' while running the docker command.

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

Below is my Cypress.env.json file

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

Error while running the docker command:

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

解决方案

Based on the comments, this needs more investigation.

In the meantime, you can use environment variables:

Create a file .env (name is not important, as long as you use the same in the next step) with the following contents:

CYPRESS_numTestsKeptInMemory=3
CYPRESS_firstNumber=1000

Run your tests in docker with:

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