柏树 - 可以在测试中分离测试时在测试中使用自定义任务

Question

我尝试在测试项目之外的插件文件中添加了一个新的自定义任务。 我还将其编译并在config.json中配置了他的路径。 该文件中的所有其他插件都可以正常运行。

我在执行过程中从柏树中获得的错误是 - ＆gt;

"value": "CypressError: `cy.task('queryDb')` failed with the following error:\n\nThe task 'queryDb' was not handled in the plugins file. The following tasks are registered: log\n\nFix this in your plugins file here:\n./../testilize/cypress/plugins/index.ts\n    at ...

配置文件扩展到测试项目之外的基本配置文件 - ＆gt;

{
  "extends": "./../testilize/cypress.json",
  "baseUrl": "https://www.blabla.com/",
  "env": {
    "client": "https://www.blabla.com/",
    "server": "https://www.blabla.com/"
  },
  "pluginsFile": "./../testilize/cypress/plugins/index.ts",
  "supportFile": "./../testilize/cypress/support/index.js",
  "fixturesFolder": "e2e-tests/fixtures",
  "integrationFolder": "e2e-tests/test-files"

这可能是因为您在插件中有两个（'task'，{部分。

第一个看起来像柏树提供的默认值，请尝试将其评论。
