TestCafe docker-无法使用运行器类运行测试

Question

我的所有测试都在 docker 容器中运行，并且运行良好。由于我有一些需要并发测试的测试文件和一个不需要并发测试的文件，这就是我需要创建一个测试运行器来运行我的测试的原因。这是我的测试运行程序类的样子：

const createTestCafe = require('testcafe');

let testcafe = null;

createTestCafe('localhost', 1337, 1338)
  .then((tc) => {
    testcafe = tc;
    const runner1 = testcafe.createRunner();
    const runner2 = testcafe.createRunner();

    const promise1 = runner1
      .src(['/tests/uitests/**/conctests/accounttest.js', '/tests/uitests/**/conctests/dashtest.js'])
      .browsers('chromium')
      .screenshots({ takeOnFails: true })
      .reporter(['spec', {
        name: 'html',
        output: 'resultsrunner1.html' }, {
        name: 'xunit',
        output: 'res1.xml',
      }])
      .concurrency(3)
      .run({
        skipJsErrors: true,
        quarantineMode: true,
      });

    const promise2 = runner2
      .src('/tests/uitests/**/conctests/roletest.js')
      .browsers('chromium')
      .screenshots({ takeOnFails: true })
      .reporter(['spec', {
        name: 'html',
        output: 'resultsrunner2.html' }, {
        name: 'xunit',
        output: 'res2.xml',
      }])
      .run({
        skipJsErrors: true,
        quarantineMode: true,
      });

    return Promise.all([promise1, promise2]);
  })
  .then(() => {
    testcafe.close();
    process.exit();
  })
  .catch((err) => {
    console.log(err);
    testcafe.close();
    process.exit(1);
  });

当我使用命令运行它时：

docker run --net=host -v `pwd`:/tests -it --entrypoint node testcafe /tests/testrunner.js

我收到此错误：

我也尝试了firefox 和chromium --no-sandbox，但没有任何效果。就我而言，我使用的是来自 TestCafe 的现有可用浏览器图像。请提出建议，因为我的所有测试现在都卡住了。

尝试使用无头浏览器。如果您需要使用浏览器 UI 运行测试，请在运行器中执行此 step 以初始化内存显示服务器。
