Cypress 和 cypress-metamask 插件问题（连接 ECONNREFUSED 127.0.0.1:9222）
我正在尝试将 cypress 测试集成到我的应用程序中，但为了执行 e2e 测试，我需要与 metamask 交互。我正在使用 cypress-metamask 插件 (https://www.npmjs.com/package/cypress -metamask），但无法让它工作。
运行测试会返回以下错误：
cy.task('setupMetamask') 失败并出现以下错误：
<块引用>请求http://localhost:9222/json/version失败，原因：连接ECONNREFUSED 127.0.0.1:9222
这是测试：
describe('NFTicket', () => {
beforeEach(() => {
cy.setupMetamask();
cy.changeMetamaskNetwork('localhost')
cy.visit('/')
});
it('is expected to display a sussess message', () => {
cy.get('[data-cy=title]').should('contain.text', 'MetaMask Detected')
});
});
这就是我的 cypress/plugins/index.js 的配置方式：
module.exports = (on, config) => {
require('cypress-metamask/plugins')(on);
on('before:browser:launch', (browser = { isHeaded: true }, arguments_) => {
if (browser.name === 'chrome') {
arguments_.args.push('--remote-debugging-port=9222')
arguments_.args.push('--disable-background-timer-throttling');
arguments_.args.push('--disable-backgrounding-occluded-windows');
arguments_.args.push('--disable-renderer-backgrounding');
}
})
}
I am trying to integrate cypress tests into my app, but in order to perform e2e tests I need to interact with metamask. I am using the cypress-metamask plugin (https://www.npmjs.com/package/cypress-metamask), but cannot get it to work.
Running the tests returns the following error:
cy.task('setupMetamask') failed with the following error:
request to http://localhost:9222/json/version failed, reason: connect ECONNREFUSED 127.0.0.1:9222
This is the test:
describe('NFTicket', () => {
beforeEach(() => {
cy.setupMetamask();
cy.changeMetamaskNetwork('localhost')
cy.visit('/')
});
it('is expected to display a sussess message', () => {
cy.get('[data-cy=title]').should('contain.text', 'MetaMask Detected')
});
});
This is how my cypress/plugins/index.js is configured:
module.exports = (on, config) => {
require('cypress-metamask/plugins')(on);
on('before:browser:launch', (browser = { isHeaded: true }, arguments_) => {
if (browser.name === 'chrome') {
arguments_.args.push('--remote-debugging-port=9222')
arguments_.args.push('--disable-background-timer-throttling');
arguments_.args.push('--disable-backgrounding-occluded-windows');
arguments_.args.push('--disable-renderer-backgrounding');
}
})
}

请确保服务器已启动，
您可以在 /etc/hosts 文件中尝试这个
127.0.0.1 localhost。Please ensure the server is started,
You can try this
127.0.0.1 localhostin /etc/hosts file.在我们的项目中，我们使用这个库也遇到了问题。我不记得具体是什么，但总的来说我们无法解决它，然后我们将其更改为 @synthetixio/synpress。在我们的项目中，使用这个库的 e2e 测试运行得很好。
可以在此处找到使用元掩码的有用命令列表< /a>.
In our project, we also encountered a problem using this library. I don't remember exactly what it was, but in general we couldn't solve it and then we changed it to @synthetixio/synpress. In our project with this library e2e tests run perfectly.
