testutils: relax regex to include just Test, Example and Benchmark as valid test functions

[buyology]

ad95b52 introduced a stricter regex for Test, Benchmark and Example to avoid matching just Test, Example or Benchmark.

These are in fact perfectly fine as function names:

package x

import "testing"

func Test(t *testing.T) {}

» go test -v
=== RUN   Test
--- PASS: Test (0.00s)
PASS
ok      x   0.007s

I didnt realize that Test, Benchmark and Example were valid names for tests. Thanks for reporting!

PRs are most welcome!

Code Pointers:

• Build and Debug the Extension
• The regular expressions to update are at https://github.com/Microsoft/vscode-go/blob/0.6.93/src/testUtils.ts#L27-L29

The fix for this is now out in the latest update to the Go extension (0.8.0)
Thanks @Charliekenney23!
