Desired functionality.

I want to generate a .spec file for already existing component / service that does not have a spec yet / has an outdated spec. More on the usecase https://stackoverflow.com/q/46276055/1990451

Mention any other details that might be useful.

A small addition: would be incredibly perfect if the just created .spec.ts files would have mocks for the every injected item according to the methods / properties that are used in the unit being tested :)

[Brocco]

Right now, specs are directly tied to the unit they're testing (component/service) and as of now there are no plans to support this, but leaving this open for discussion purposes.

Yes generating a spec file after we already generated our component and modified it.
ng g component your-component --spec-only

[michaelbazos]

What I do to generate the spec file for an already existing component:

ng generate component [name]

And then answer "no" to the "Overwrite ..." questions regarding already existing, non-spec, files.

EDIT: this is not possible in the current version (1.6.0) of angular-cli, as it would prompt the component already exists and would not generate any file.

@michaelbazos it doesn't work, it simply notifies that the component already exists.

I'd like to add my vote for this.
Even if it was only able to create the "[object] works!" type test, it would still save on boilerplate.

[michaelbazos]

@darkbasic Indeed, just updated my version of angular-cli to 1.6.0, and it seems no file is generated if any of the [component | template | spec | stylesheet] already exists. Previously I was on 1.4.x, and it used to create non existing files, and ask for already existing ones.

[smnbbrv]

So, it's a misdocumented feature then? @Brocco can you confirm it's the right way to do stuff?

[BBaysinger]

Also, say I have an entire project w/o .spec files. There should be a way to create them all from a single command.

[AngelZatch]

Agreeing with this. I'm currently reconstructing a project and the previous devs manually deleted spec files, my afternoon's very long.
