snippet: Add table testing boilerplate snippet

[mtyurt]

The snippet only considers string input / output, and it needs to be modified for each test case, but it provides a clean, parallel testing compatible table testing boilerplate code.

Let me know if you have suggestions about tab stops or snippet name.

Thanks!

This seems very specific for your personal use-case though. I'm not sure if adding it to vim-go is a good idea.

(also, as a general point, you should probably use subtests and print errors as aligned output).

[mtyurt]

Thanks for the feedback. If you don't see any future even when it's modified properly according to Effective Go best practices, I can keep this one in my personal snippets :)

[arp242]

If that is from Effective Go then that document should be updated/changed.

@mtyurt, if you'll modify it so that each entry in the table has a name, the tests are run via `

t.Run(tt.name, func(t *testing.T) {
   ...
})

and all the snippet is available to all of vim-go's supported engines, I'm sure we can get this merged.

[mtyurt]

I have updated the snippet to use subtests and added minisnip / neosnip versions as well.

This looks good. Only change I would recommend is to change the name testtable (it's a tad long). Let's use tt.

[mtyurt]

That's quite a better name, I hope it doesn't confuse people :)

Renamed to tt

[fatih]

@mtyurt true, but then a long name means you need to write a lot, which is an anti-pattern for a snippet. We already have many 2-3 char snippets (i.e: err, errf, hf, etc..). People get used to it so it's not a big issue :)
