src/goTest: support running sub-tests
Changes the logic for creating sub-tests on the fly. Prevously, test IDs were created in such a way that it was impractical to support running subtests. This changes the way IDs are created for subtests such that running subtests is simple. Additionally, this CL updates 'goTest' to run `go test -run=^$ -bench ^BenchmarkFoo/Bar$` (without the parentheses) when a single benchmark is selected, as a hack to get around golang/go#47800. Updates #1641 Change-Id: I26eac8a5a396df3923073274ed93d9c59107d9c3 Reviewed-on: https://go-review.googlesource.com/c/vscode-go/+/343433 Reviewed-by: Hyang-Ah Hana Kim <[email protected]> Trust: Hyang-Ah Hana Kim <[email protected]> Trust: Rebecca Stambler <[email protected]> Run-TryBot: Hyang-Ah Hana Kim <[email protected]> TryBot-Result: kokoro <[email protected]>
