我所有的测试都在docker容器中运行，并且工作正常。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，因此我需要创建一个测试运行器来运行我的测试。这是我的测试跑步者类的样子：

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',output: 'resultsrunner2.html' },output: 'res2.xml',}])
      .run({
        skipJsErrors: 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：

我也尝试过firefox和chromium --no-sandbox，但对我没有任何帮助。就我而言，我正在使用TestCafe中现有的浏览器图像。请提出建议，因为我的所有测试都已停滞。
