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:.

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. |
