Austin Clements 5918101d67 testing: detect a stopped timer in B.Loop Currently, if the user stops the timer in a B.Loop benchmark loop, the benchmark will run until it hits the timeout and fails. Fix this by detecting that the timer is stopped and failing the benchmark right away. We avoid making the fast path more expensive for this check by "poisoning" the B.Loop iteration counter when the timer is stopped so that it falls back to the slow path, which can check the timer. This causes b to escape from B.Loop, which is totally harmless because it was already definitely heap-allocated. But it causes the test/inline_testingbloop.go errorcheck test to fail. I don't think the escape messages actually mattered to that test, they just had to be matched. To fix this, we drop the debug level to -m=1, since -m=2 prints a lot of extra information for escaping parameters that we don't want to deal with, and change one error check to allow b to escape. Fixes #72971.

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

it is most naturally expressed using the test runner; or
it is also applicable to gccgo and other Go tool chains.
