Overview.
$ ./configure && make tests
You'll see some progress info. A failure will cause either the make to
abort or the driver script to report a "FATAL" failure.
The test consists of 2 parts. The first is the file-based tests which is
driven by the Makefile, and the second is a set of network or proxycommand
based tests, which are driven by a driver script (test-exec.sh) which is
called multiple times by the Makefile.
Failures in the first part will cause the Makefile to return an error.
Failures in the second part will print a "FATAL" message for the failed
test and continue.
OpenBSD has a system-wide regression test suite. OpenSSH Portable's test
suite is based on OpenBSD's with modifications.
Environment variables.
SKIP_UNIT: Skip unit tests.
SUDO: path to sudo/doas command, if desired. Note that some systems
(notably systems using PAM) require sudo to execute some tests.
LTESTS: Whitespace separated list of tests (filenames without the .sh
extension) to run.
OBJ: used by test scripts to access build dir.
TEST_SHELL: shell used for running the test scripts.
TEST_SSH_FAIL_FATAL: set to "yes" to make any failure abort the test
currently in progress.
TEST_SSH_PORT: TCP port to be used for the listening tests.
TEST_SSH_QUIET: set to "yes" to suppress non-fatal output.
TEST_SSH_SSHD_CONFOPTS: Configuration directives to be added to sshd_config
before running each test.
TEST_SSH_SSH_CONFOPTS: Configuration directives to be added to
ssh_config before running each test.
TEST_SSH_TRACE: set to "yes" for verbose output from tests
TEST_SSH_x: path to "ssh" command under test, where x is one of
SSH, SSHD, SSHAGENT, SSHADD, SSHKEYGEN, SSHKEYSCAN, SFTP or
SFTPSERVER
USE_VALGRIND: Run the tests under valgrind memory checker.
Individual tests.
You can run an individual test from the top-level Makefile, eg:
$ make tests LTESTS=agent-timeout
If you need to manipulate the environment more you can invoke test-exec.sh
directly if you set up the path to find the binaries under test and the
test scripts themselves, for example:
$ cd regress
$ PATH=`pwd`/..:$PATH:. TEST_SHELL=/bin/sh sh test-exec.sh `pwd` \
agent-timeout.sh
ok agent timeout test
Files.
test-exec.sh: the main test driver. Sets environment, creates config files
and keys and runs the specified test.
At the time of writing, the individual tests are:
agent-timeout.sh: agent timeout test
agent.sh: simple agent test
broken-pipe.sh: broken pipe test
connect-privsep.sh: proxy connect with privsep
connect.sh: simple connect
exit-status.sh: remote exit status
forwarding.sh: local and remote forwarding
keygen-change.sh: change passphrase for key
keyscan.sh: keyscan
proto-mismatch.sh: protocol version mismatch
proto-version.sh: sshd version with different protocol combinations
proxy-connect.sh: proxy connect
sftp.sh: basic sftp put/get
ssh-com-client.sh: connect with ssh.com client
ssh-com-keygen.sh: ssh.com key import
ssh-com-sftp.sh: basic sftp put/get with ssh.com server
ssh-com.sh: connect to ssh.com server
stderr-after-eof.sh: stderr data after eof
stderr-data.sh: stderr data transfer
transfer.sh: transfer data
try-ciphers.sh: try ciphers
yes-head.sh: yes pipe head
Problems?
Run the failing test with shell tracing (-x) turned on:
$ PATH=`pwd`/..:$PATH:. sh -x test-exec.sh `pwd` agent-timeout.sh
Failed tests can be difficult to diagnose. Suggestions:
- run the individual test via ./test-exec.sh `pwd` [testname]
- set LogLevel to VERBOSE in test-exec.sh and enable syslogging of
auth.debug (eg to /var/log/authlog).
Known Issues.
- Similarly, if you do not have "scp" in your system's $PATH then the
multiplex scp tests will fail (since the system's shell startup scripts
will determine where the shell started by sshd will look for scp).
- Recent GNU coreutils deprecate "head -[n]": this will cause the yes-head
test to fail. The old behaviour can be restored by setting (and
exporting) _POSIX2_VERSION=199209 before running the tests.
