测试失败 - 测试编译时间太长。确保测试代码没有过多导入

Question

我们的团队测试有时无法在 CI/CD (GitLab) 上运行，给出的提示之一是过度导入。是否有关于如何减少进口以避免此问题的建议，或有任何其他建议来阻止这种情况间歇性发生？

另外，为什么过度导入可能会影响浏览器连接？

这是错误：

ERROR Cannot establish one or more browser connections.
8 of 8 browser connections have not been established:
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
 - chrome:headless --no-sandbox --disable-dev-shm-usage
Hints:
 - Tests took too long to compile (2.03 min). Ensure the test code has no excessive imports.
 - The host machine may not be powerful enough to handle the specified concurrency factor (8). Decrease the concurrency factor or allocate more computing resources to the host machine.
 - Increase the Browser Initialization Timeout if its value is too low (currently: 2 minutes for local browsers and 6 minutes for remote browsers). The timeout determines how long TestCafe waits for browsers to be ready.
 - The error can also be caused by network issues or remote device failure. Make sure that your network connection is stable and you can reach the remote device.

该错误同时指向浏览器初始化超时（2 分钟）和并发因素（同时 8 个浏览器）。尝试增加超时并减少并发系数，直到定期成功。如果它以不同方式失败，请从官方文档中查看其他常见问题，了解其他事情，您可以尝试优化以及如何执行此操作的提示。

导入需要时间来加载和解析，JavaScript 也需要进行 JIT（及时，“在运行文件之前”）编译。坏代码可能需要多次重新编译，因为它想“再试一次”来优化它。从无限循环到高延迟外部 API，存在太多潜在问题，这些问题可能在运行代码来初始化导入或运行它们时发生。最好的办法是使用调试来尝试找到瓶颈。
