2023-05-04internal/testenv: remove HasExec and simplify other support checks againBryan C. Mills
HasExec is an attractive nuisance: it is tempting to check in a TestMain function, but TestMain really shouldn't be running subprocesses eagerly anyway (they add needless overhead for operations like 'go test -list=.'), and the trick of re-executing the test binary to determine whether 'exec' works ends up in infinite recursion if TestMain itself calls HasExec. Instead, tests that need to execute a subprocess should call MustHaveExec or MustHaveExecPath from within a specific test, or just try to exec the program and check its error status (perhaps using testenv.SyscallIsNotSupported). While I'm in here and testing on the SlowBots anyway, a few other cleanups relating to subprocesses: - Add more t.Helper calls to support checks where appropriate. - Remove findGoTool, which can be simplified to exec.LookPath as of CL 404134. - Add tests confirming the expected behavior of the support functions on the Go project's builders.

2023-02-02internal/testenv: avoid rebuilding all of std in WriteImportcfgBryan C. Mills
Instead, have the caller pass in an explicit list of the packages (if any) they need. After #47257, a builder running a test does not necessarily have the entire standard library already cached, especially when running tests in sharded mode. testenv.WriteImportcfg used to write an importcfg for the entire standard library — which required rebuilding the entire standard library — even though most tests need only a tiny subset. This reduces the time to test internal/abi with a cold build cache on my workstation from ~16s to ~0.05s. It somewhat increases the time for 'go test go/internal/gcimporter' with a cold cache, from ~43s to ~54s, presumably due to decreased parallelism in rebuilding the standard library and increased overhead in re-resolving the import map. However, 'go test -short' running time remains stable (~5.5s before and after). Fixes #58248.

2022-12-01go/internal/gcimporter: load cached export data for packages individuallyBryan C. Mills
Previously, we were using internal/goroot.PkgfileMap to locate cached export data. However, PkgfileMap regenerates export data for the entire standard library, whereas gcimporter may only need a single package. Under the new approach, we load the export data (still using 'go list -export') for each GOROOT package individually, avoiding work to rebuild export data for packages that are not needed. This is a tradeoff: if most packages in GOROOT are actually needed, we end up making many more calls to 'go list', and may build packages sequentially instead of in parallel (but with lower latency to start using the export data from the earlier packages). On my workstation, starting from a clean cache for each run, this reduces the wall time of 'go test go/internal/gcimporter -run=TestImportedTypes' from 22s real time (2m10s user time) to 6s real (27s user), and only increases 'go test go/internal/gcimporter' from 28s real (2m16s user) to 30s real (2m19s user).

For most tests, the test's deadline itself is more appropriate than an arbitrary timeout layered atop of it (especially once #48157 is implemented), and testenv.Command already adds cleaner timeout behavior when a command would run too close to the test's deadline. That makes RunWithTimeout something of an attractive nuisance. For now, migrate the two existing uses of it to testenv.CommandContext, with a shorter timeout implemented using context.WithTimeout.

2022-10-31internal/testenv: add CommandContext and CommandBryan C. Mills
This adds a testenv.CommandContext function, with timeout behavior based on the existing logic in cmd/go.TestScript: namely, the command is terminated with SIGQUIT (if supported) with an arbitrary grace period remaining until the test's deadline. If the test environment does not support executing subprocesses, CommandContext skips the test. If the command is terminated due to the timout expiring or the test fails to wait for the command after starting it, CommandContext marks the test as failing. For tests where a shorter timeout is desired (such as for fail-fast behavior), one may be supplied using context.WithTimeout. The more concise Command helper is like CommandContext but without the need to supply an explicit Context. Updates #50436.

2022-10-04cmd/internal/sys: migrate support.go functions to new internal pkgThan McIntosh
Separate out the functions from cmd/internal/sys/support.go and migrate them to a new package internal/platform, so that functions such as "RaceDetectorSupported" can be called from tests in std as well as in cmd. This isn't a complete move of everything in cmd/internal/sys; there are still many functions left. The original version of this CL (patch set 1) called the new package "internal/sys", but for packages that needed both "internal/sys" and "cmd/internal/sys" the import of the former had to be done with a different name, which was confusing and also required a hack in cmd/dist.

2022-06-13sync: move lock linearity test and treat it like a performance testMichael Anthony Knyszek
This change moves test/locklinear.go into the sync package tests, and adds a bit of infrastructure since there are other linearity-checking tests that could benefit from it too. This infrastructure is also different than what test/locklinear.go does: instead of trying really hard to get at least one success, we instead treat this like a performance test and look for a significant difference via a t-test. This makes the methodology behind the tests more rigorous, and should reduce flakiness as transient noise should produce an insignificant result. A follow-up CL does more to make these tests even more robust. For #32986.

2019-10-09cmd/go: fail if a test binary exits with no outputDaniel Martí
For example, if a test calls os.Exit(0), that could trick a 'go test' run into not running some of the other tests, and thinking that they all succeeded. This can easily go unnoticed and cause developers headaches. Add a simple sanity check as part of 'go test': if the test binary succeeds and doesn't print anything, we should error, as something clearly went very wrong. This is done by inspecting each of the stdout writes from the spawned process, since we don't want to read the entirety of the output into a buffer. We need to introduce a "buffered" bool var, as there's now an io.Writer layer between cmd.Stdout and &buf. A few TestMain funcs in the standard library needed fixing, as they returned without printing anything as a means to skip testing the entire package. For that purpose add testenv.MainMust, which prints a warning and prints SKIP, similar to when -run matches no tests. Finally, add tests for both os.Exit(0) and os.Exit(1), both as part of TestMain and as part of a single test, and test that the various stdout modes still do the right thing. Fixes #29062.
