1The test directory contains tests of the Go tool chain and runtime. 2It includes black box tests, regression tests, and error output tests. 3They are run as part of all.bash. 4 5To run just these tests, execute: 6 7 ../bin/go test cmd/internal/testdir 8 9To run just tests from specified files in this directory, execute: 10 11 ../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)' 12 13Standard library tests should be written as regular Go tests in the appropriate package. 14 15The tool chain and runtime also have regular Go tests in their packages. 16The main reasons to add a new test to this directory are: 17 18* it is most naturally expressed using the test runner; or 19* it is also applicable to `gccgo` and other Go tool chains. 20
