问题
I'm using TeamCity 10 and trying to get an @angular/cli project to do the following in a build step:
Everything runs fine until the e2e script. It halts the build and I have to force shut it down.
So I logged onto my build agent remotely and tried running the command ng e2e myself in the location of the code it just pulled, and I get a chrome browser window to come up, but within 10 seconds it crashes with the following errors:
PS C:\TeamCity\BuildAgent\work\4038db2ebec7f79b> npm run e2e
> tdportal@0.0.0 e2e C:\TeamCity\BuildAgent\work\4038db2ebec7f79b
> ng e2e

Why can't I run my e2e tests on this machine if everything else works? What do I need to do differently?
回答1:
The E2E tests require Chrome being launched on the TeamCity agent in order to run the tests, and since the agent is running without interacting with the desktop, you can't run your E2E tests with Chrome. Instead, you need to configure Karma to run your E2E tests with PhantomJs. Phantom is a headless browser and works without having to interact with the desktop. Let me know if you need an example, I have to dig out mine.
