Provide a test runner about deno_std

[hayd]

Yes, this will be cli only, at least initially. It will import from filenames that match /(.+_)?test\.ts$/ but could later take a glob as an arg. It also will --grep on test name if passed (only run matching tests). More features could be added in the future...

FYI I'm working on it

An inbuilt test runner is not a bad idea. But at this stage I probably wouldn't write / consume any config files. That seems a second-order priority to getting parallelisation and file watching going. Besides, convention > configuration.

[hayd]

I have an implementation for this, but am waiting on import() to be supported in deno.
(It was in ~0.2.8 and the test runner was working.)

Note: After #192 walking is easy, and if we wanted to support glob as a cli we could move https://github.com/hayd/deno-globrex over to std (or port something else).

Besides, convention > configuration.

Especially while Deno is still new and it’s possible to get everyone to follow the convention.

I also agree that convention > configuration, so I'll support you in following the _test suffix.
