@ -36,9 +36,14 @@ The package is built in a special subdirectory so it does not
interfere with the non-test installation.
Usage:
gotest [pkg_test.go ...]
gotest [-c] [-x] [testflags...] [pkg_test.go...]
The resulting binary, called (for amd64) 6.out, has several flags.
The flags specific to gotest include -x, which prints each subcommand
gotest executes, and -c, which causes gotest to compile the test
binary but not run it. The testflags are passed to the test binary
and are documented below.
The resulting test binary, called (for amd64) 6.out, has several flags.
Usage:
6.out [-test.v] [-test.run pattern] [-test.bench pattern] \
@ -70,5 +75,12 @@ The -test.short package tells long-running tests to shorten their
run time. It is off by default but set by all.bash so installations
of the Go tree can do a sanity check but not spend time running the
full test suite.
For convenience, each -test.X flag of the test binary is also
available as the flag -X in gotest itself. For instance, the command
gotest -v -test.cpuprofile=prof.out
will compile the test binary and then run it as
6.out -test.v -cpuprofile=prof.out
