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:
test: use the version of Go used to run run.go Currently, the top-level testsuite always uses whatever version of Go is found in the PATH to execute all the tests. This forces the developers to tweak the PATH to run the testsuite. Change it to use the same version of Go used to run run.go. This allows developers to run the testsuite using the tip compiler by simply saying "../bin/go run run.go". I think this is a better solution compared to always forcing "../bin/go", because it allows developers to run the testsuite using different Go versions, for instance to check if a new test is fixed in tip compared to the installed compiler.

test: document specifying individual test files as operands The current command will run this entire set of tests, which takes a noticeable amount of time. Contributors may wish to run only a subset of these tests to save time/compute (e.g. when iterating on a CL that failed tests in that subset). Listing file(s) as operands to the command will run only those tests.

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.
