command line, turning warnings into errors. That makes it
impossible to miss warnings generated by the build.
+ To build with gcov code coverage support, add --enable-coverage,
+ e.g.:
+
+ % ./configure --enable-coverage
+
The configure script accepts a number of other options and honors
additional environment variables. For a full list, invoke
configure with the --help option.
startup scripts for Debian, XenServer and RHEL use ovs-ctl's functions and it
is recommended that these functions be used for other software platforms too.
-Running the Testsuite
-=====================
+Testsuites
+==========
+
+This section describe Open vSwitch's built-in support for various test
+suites. You must configure and build Open vSwitch (steps 1 through 3
+in "Building and Installing Open vSwitch for Linux, FreeBSD or NetBSD"
+above) before you run the tests described here. You do not need to
+install Open vSwitch or to build or load the kernel module to run
+these test suites. You do not need supervisor privilege to run these
+test suites.
-Open vSwitch includes a testsuite. Before you submit patches
+Self-Tests
+----------
+
+Open vSwitch includes a suite of self-tests. Before you submit patches
upstream, we advise that you run the tests and ensure that they pass.
If you add new features to Open vSwitch, then adding tests for those
features will ensure your features don't break as developers modify
other areas of Open vSwitch.
-You must configure and build Open vSwitch (steps 1 through 3 in
-"Building and Installing Open vSwitch for Linux, FreeBSD or NetBSD" above)
-before you run the testsuite. You do not need to install Open vSwitch
-or to build or load the kernel module to run the testsuite. You do
-not need supervisor privilege to run the testsuite.
+Refer to "Testsuites" above for prerequisites.
To run all the unit tests in Open vSwitch, one at a time:
make check
you find that a test fails intermittently, please report it, since the
developers may not have noticed.
+OFTest
+------
+
+OFTest is an OpenFlow protocol testing suite. Open vSwitch includes a
+Makefile target to run OFTest with Open vSwitch in "dummy mode". In
+this mode of testing, no packets travel across physical or virtual
+networks. Instead, Unix domain sockets stand in as simulated
+networks. This simulation is imperfect, but it is much easier to set
+up, does not require extra physical or virtual hardware, and does not
+require supervisor privileges.
+
+To run OFTest with Open vSwitch, first read and follow the
+instructions under "Testsuites" above. Second, obtain a copy of
+OFTest and install its prerequisites. You need a copy of OFTest that
+includes commit 406614846c5 (make ovs-dummy platform work again).
+This commit was merged into the OFTest repository on Feb 1, 2013, so
+any copy of OFTest more recent than that should work. Testing OVS in
+dummy mode does not require root privilege, so you may ignore that
+requirement.
+
+Optionally, add the top-level OFTest directory (containing the "oft"
+program) to your $PATH. This slightly simplifies running OFTest later.
+
+To run OFTest in dummy mode, run the following command from your Open
+vSwitch build directory:
+ make check-oftest OFT=<oft-binary>
+where <oft-binary> is the absolute path to the "oft" program in
+OFTest.
+
+If you added "oft" to your $PATH, you may omit the OFT variable
+assignment:
+ make check-oftest
+By default, "check-oftest" passes "oft" just enough options to enable
+dummy mode. You can use OFTFLAGS to pass additional options. For
+example, to run just the basic.Echo test instead of all tests (the
+default) and enable verbose logging:
+ make check-oftest OFT=<oft-binary> OFTFLAGS='--verbose -T basic.Echo'
+
+If you use OFTest that does not include commit 4d1f3eb2c792 (oft:
+change default port to 6653), merged into the OFTest repository in
+October 2013, then you need to add an option to use the IETF-assigned
+controller port:
+ make check-oftest OFT=<oft-binary> OFTFLAGS='--port=6653'
+
+Please interpret OFTest results cautiously. Open vSwitch can fail a
+given test in OFTest for many reasons, including bugs in Open vSwitch,
+bugs in OFTest, bugs in the "dummy mode" integration, and differing
+interpretations of the OpenFlow standard and other standards.
+
+Open vSwitch has not been validated against OFTest. Please do report
+test failures that you believe to represent bugs in Open vSwitch.
+Include the precise versions of Open vSwitch and OFTest in your bug
+report, plus any other information needed to reproduce the problem.
+
+Ryu
+---
+
+Ryu is an OpenFlow controller written in Python that includes an
+extensive OpenFlow testsuite. Open vSwitch includes a Makefile target
+to run Ryu in "dummy mode". See "OFTest" above for an explanation of
+dummy mode.
+
+To run Ryu tests with Open vSwitch, first read and follow the
+instructions under "Testsuites" above. Second, obtain a copy of Ryu,
+install its prerequisites, and build it. You do not need to install
+Ryu (some of the tests do not get installed, so it does not help).
+
+To run Ryu tests, run the following command from your Open vSwitch
+build directory:
+ make check-ryu RYUDIR=<ryu-source-dir>
+where <ryu-source-dir> is the absolute path to the root of the Ryu
+source distribution. The default <ryu-source-dir> is $srcdir/../ryu
+where $srcdir is your Open vSwitch source directory, so if this
+default is correct then you make simply run "make check-ryu".
+
+Open vSwitch has not been validated against Ryu. Please do report
+test failures that you believe to represent bugs in Open vSwitch.
+Include the precise versions of Open vSwitch and Ryu in your bug
+report, plus any other information needed to reproduce the problem.

- How to Use OFTest With Open vSwitch
- ===================================
-
-This document describes how to use the OFTest OpenFlow protocol
-testing suite with Open vSwitch in "dummy mode". In this mode of
-testing, no packets travel across physical or virtual networks.
-Instead, Unix domain sockets stand in as simulated networks. This
-simulation is imperfect, but it is much easier to set up, does not
-require extra physical or virtual hardware, and does not require
-supervisor privileges.
-
-Prerequisites
--------------
-
-First, build Open vSwitch according to the instructions in INSTALL.
-You need not install it.
-
-Second, obtain a copy of OFTest and install its prerequisites. You
-need a copy of OFTest that includes commit 406614846c5 (make ovs-dummy
-platform work again). This commit was merged into the OFTest
-repository on Feb 1, 2013, so any copy of OFTest more recent than that
-should work.
-
-Testing OVS in dummy mode does not require root privilege, so you may
-ignore that requirement.
-
-Optionally, add the top-level OFTest directory (containing the "oft"
-program) to your $PATH. This slightly simplifies running OFTest later.
-
-Running OFTest
---------------
-
-To run OFTest in dummy mode, run the following command from your Open
-vSwitch build directory:
-
- make check-oftest OFT=<oft-binary>
-
-where <oft-binary> is the absolute path to the "oft" program in
-OFTest.
-
-If you added "oft" to your $PATH, you may omit the OFT variable
-assignment:
-
- make check-oftest
-
-By default, "check-oftest" passes "oft" just enough options to enable
-dummy mode. You can use OFTFLAGS to pass additional options. For
-example, to run just the basic.Echo test instead of all tests (the
-default) and enable verbose logging:
-
- make check-oftest OFT=<oft-binary> OFTFLAGS='--verbose -T basic.Echo'
-
-If you use OFTest that does not include commit 4d1f3eb2c792 (oft:
-change default port to 6653), merged into the OFTest repository in
-October 2013, then you need to add an option to use the IETF-assigned
-controller port:
-
- make check-oftest OFT=<oft-binary> OFTFLAGS='--port=6653'
-
-Interpreting OFTest Results
----------------------------
-
-Please interpret OFTest results cautiously. Open vSwitch can fail a
-given test in OFTest for many reasons, including bugs in Open vSwitch,
-bugs in OFTest, bugs in the "dummy mode" integration, and differing
-interpretations of the OpenFlow standard and other standards.
-
-Open vSwitch has not been validated against OFTest. Please do report

-Building with gcov support
-==========================
-
-The Open vSwitch "configure" script supports the following
-code-coverage related options:
-
- --disable-coverage
- --enable-coverage=no
-
- Do not build with gcov code coverage support.
-
- This is the default if no coverage option is passed to
- "configure".
-
- --enable-coverage
- --enable-coverage=yes
-
- Build with gcov code coverage support.
