Desired functionality.

Should run unit tests

Mention any other details that might be useful.

I believe this issue might be related to the last updated on ngtools/webpack . Specifically from version 1.3.1 to 1.3.2.

[onuralps]

Same problem here

[ashfaqch]

I am having same issue since this morning!

angular-cli: 1.0.0-beta.26

[smileLilith]

+1 since yesterday and upgrading from angular-cli v1.0.0-beta.30 to v1.0.6
added missing tsconfig.spec.ts has solved issue

[onuralps]

for me adding "@ ngtools/webpack": "1.3.0" to package.json solved the issue for now but i am not an expert and do not know if there is any side effect.

[eng-almeida]

@smileLilith what do you mean adding tsconfig.spec.ts? Can you be more specific, providing an example? @onuralps I also did that (in my case was ngtools/webpack 1.3.1) has a temporary solution. I think we should not override ngtools/webpack, otherwise we may face new problems on future releases from angular-cli.

This PR with a revert commit fixed the problem #6463
Thanks @hansl
