# Guidelines
This document describes how to use the topotests testing framework.
## Executing Tests
To run the whole suite of tests the following commands must be executed at the
top level directory of topotest:
```shell
$ # Change to the top level directory of topotests.
$ cd path/to/topotests
$ # Tests must be run as root, since Mininet requires it.
$ sudo pytest
```
In order to run a specific test, you can use the following command:
```shell
$ # running a specific topology
$ sudo pytest ospf-topo1/
$ # or inside the test folder
$ cd ospf-topo1
$ sudo pytest # to run all tests inside the directory
$ sudo pytest test_ospf_topo1.py # to run a specific test
$ # or outside the test folder
$ cd ..
$ sudo pytest ospf-topo1/test_ospf_topo1.py # to run a specific one
```
The output of the tested daemons will be available at the temporary folder of
your machine:
```shell
$ ls /tmp/topotest/ospf-topo1.test_ospf-topo1/r1
...
zebra.err # zebra stderr output
zebra.log # zebra log file
zebra.out # zebra stdout output
...
```
You can also run memory leak tests to get reports:
```shell
$ # Set the environment variable to apply to a specific test...
$ sudo env TOPOTESTS_CHECK_MEMLEAK="/tmp/memleak_report_" pytest ospf-topo1/test_ospf_topo1.py
$ # ...or apply to all tests adding this line to the configuration file
$ echo 'memleak_path = /tmp/memleak_report_' >> pytest.ini
$ # You can also use your editor
$ $EDITOR pytest.ini
$ # After running tests you should see your files:
$ ls /tmp/memleak_report_*
memleak_report_test_ospf_topo1.txt
```
## Writing a New Test
This section will guide you in all recommended steps to produce a standard
topology test.
This is the recommended test writing routine:
* Write a topology (Graphviz recommended)
* Obtain configuration files
* Write the test itself
* Create a Pull Request
### Topotest File Hierarchy
Before starting to write any tests one must know the file hierarchy. The
repository hierarchy looks like this:
```shell
$ cd path/to/topotest
$ find ./*
...
./README.md # repository read me
./GUIDELINES.md # this file
./conftest.py # test hooks - pytest related functions
./example-test # example test folder
./example-test/__init__.py # python package marker - must always exist.
./example-test/test_template.jpg # generated topology picture - see next section
./example-test/test_template.dot # Graphviz dot file
./example-test/test_template.py # the topology plus the test
...
./ospf-topo1 # the ospf topology test
./ospf-topo1/r1 # router 1 configuration files
./ospf-topo1/r1/zebra.conf # zebra configuration file
./ospf-topo1/r1/ospfd.conf # ospf configuration file
./ospf-topo1/r1/ospfroute.txt # 'show ip ospf' output reference file
# removed other for shortness sake
...
./lib # shared test/topology functions
./lib/topogen.py # topogen implementation
./lib/topotest.py # topotest implementation
```
Guidelines for creating/editing topotest:
* New topologies that don't fit the existing directories should create its own
* Always remember to add the `__init__.py` to new folders, this makes auto
complete engines and pylint happy
* Router (Quagga/FRR) specific code should go on topotest.py
* Generic/repeated router actions should have an abstraction in
topogen.TopoRouter.
* Generic/repeated non-router code should go to topotest.py
* pytest related code should go to conftest.py (e.g. specialized asserts)
### Defining the Topology
The first step to write a new test is to define the topology. This step can be
done in many ways, but the recommended is to use Graphviz to generate a drawing
of the Topology. It allows us to see the topology graphically and to see the
names of equipments, links and addresses.
Here is an example of Graphviz dot file that generates the
[template topology](example-test/test_template.dot) (the inlined code might get
outdated, please see the linked file):
```dot
graph template {
label="template";
# Routers
r1 [
shape=doubleoctagon,
label="r1",
fillcolor="#f08080",
style=filled,
];
r2 [
shape=doubleoctagon,
label="r2",
fillcolor="#f08080",
style=filled,
];
# Switches
s1 [
shape=oval,
label="s1\n192.168.0.0/24",
fillcolor="#d0e0d0",
style=filled,
];
s2 [
shape=oval,
label="s2\n192.168.1.0/24",
fillcolor="#d0e0d0",
style=filled,
];
# Connections
r1 -- s1 [label="eth0\n.1"];
r1 -- s2 [label="eth1\n.100"];
r2 -- s2 [label="eth0\n.1"];
}
```
Here is the produced graph:
![template topology graph](example-test/test_template.jpg)
### Generating / Obtaining Configuration Files
In order to get the configuration files or command output for each router, we
need to run the topology and execute commands in vtysh. The quickest way to
achieve that is writing the topology building code and running the topology.
To bootstrap your test topology, do the following steps:
* Copy the template test
```shell
$ mkdir new-topo/
$ touch new-topo/__init__.py
$ cp example-test/test_template.py new-topo/test_new_topo.py
```
* Modify the template according to your dot file
Here is the template topology described in the previous section in python code:
```py
class TemplateTopo(Topo):
"Test topology builder"
def build(self, *_args, **_opts):
"Build function"
tgen = get_topogen(self)
# Create 2 routers
for routern in range(1, 3):
tgen.add_router('r{}'.format(routern))
# Create a switch with just one router connected to it to simulate a
# empty network.
switch = tgen.add_switch('s1')
switch.add_link(tgen.gears['r1'])
# Create a connection between r1 and r2
switch = tgen.add_switch('s2')
switch.add_link(tgen.gears['r1'])
switch.add_link(tgen.gears['r2'])
```
* Run the topology
Topogen allows us to run the topology without running any tests, you can do that
using the following example commands:
```shell
$ # Running your bootstraped topology
$ sudo pytest -s --topology-only new-topo/test_new_topo.py
$ # Running the test_template.py topology
$ sudo pytest -s --topology-only example-test/test_template.py
$ # Running the ospf_topo1.py topology
$ sudo pytest -s --topology-only ospf-topo1/test_ospf_topo1.py
```
Parameters explanation:
* `-s`: actives input/output capture. This is required by mininet in order to show
the interactive shell.
* `--topology-only`: don't run any tests, just build the topology.
After executing the commands above, you should get the following terminal
output:
```shell
=== test session starts ===

The last line shows us that we are now using the Mininet CLI (Command Line
Interface), from here you can call your router vtysh or even bash.
Here are some commands example:
```shell

### Writing Tests
Test topologies should always be bootstrapped from the
[example-test/test_template.py](example-test/test_template.py),
because it contains important boilerplate code that can't be avoided, like:
* imports: os, sys, pytest, topotest/topogen and mininet topology class
* The global variable CWD (Current Working directory): which is most likely
going to be used to reference the routers configuration file location
Example:
```py
# For all registered routers, load the zebra configuration file
for rname, router in router_list.iteritems():
router.load_config(
TopoRouter.RD_ZEBRA,
os.path.join(CWD, '{}/zebra.conf'.format(rname))
)
# os.path.join() joins the CWD string with arguments adding the necessary
# slashes ('/'). Arguments must not begin with '/'.
```
* The topology class that inherits from Mininet Topo class
```py
class TemplateTopo(Topo):
def build(self, *_args, **_opts):
tgen = get_topogen(self)
# topology build code
```
* pytest `setup_module()` and `teardown_module()` to start the topology
```py
def setup_module(_m):
tgen = Topogen(TemplateTopo)
tgen.start_topology('debug')
def teardown_module(_m):
tgen = get_topogen()
tgen.stop_topology()
```
* `__main__` initialization code (to support running the script directly)
```py
if __name__ == '__main__':
sys.exit(pytest.main(["-s"]))
```
Requirements:
* Test code should always be declared inside functions that begin with the
`test_` prefix. Functions beginning with different prefixes will not be run by
pytest.
* Configuration files and long output commands should go into separated files
inside folders named after the equipment.
* Tests must be able to run without any interaction. To make sure your test
conforms with this, run it without the `-s` parameter.
Tips:
* Keep results in stack variables, so people inspecting code with `pdb` can
easily print their values.
Don't do this:
```py
assert foobar(router1, router2)
```
Do this instead:
```py
result = foobar(router1, router2)
assert result
```
* Use `assert` messages to indicate where the test failed.
Example:
```py
for router in router_list:
# ...
assert condition, 'Router "{}" condition failed'.format(router.name)
```
### Debugging Execution
The most effective ways to inspect topology tests are:
* Run pytest with `--pdb` option. This option will cause a pdb shell to appear
when an assertion fails
Example: `pytest -s --pdb ospf-topo1/test_ospf_topo1.py`
* Set a breakpoint in the test code with `pdb`
Example:
```py
# Add the pdb import at the beginning of the file
import pdb
# ...
# Add a breakpoint where you think the problem is
def test_bla():
# ...
pdb.set_trace()
# ...
```
The [Python Debugger](https://docs.python.org/2.7/library/pdb.html) (pdb) shell
allows us to run many useful operations like:
* Setting breaking point on file/function/conditions (e.g. `break`, `condition`)
* Inspecting variables (e.g. `p` (print), `pp` (pretty print))
* Running python code
TIP: The TopoGear (equipment abstraction class) implements the `__str__` method
that allows the user to inspect equipment information.
Example of pdb usage:
```shell
> /media/sf_src/topotests/ospf-topo1/test_ospf_topo1.py(121)test_ospf_convergence()

To enable more debug messages in other Topogen subsystems (like Mininet), more
logging messages can be displayed by modifying the test configuration file
`pytest.ini`:
```ini
[topogen]
# Change the default verbosity line from 'info'...
#verbosity = info
# ...to 'debug'
verbosity = debug
```

# FRRouting Topology Tests with Mininet
## Guidelines
Instructions for use, write or debug topologies can be found in the
[guidelines](GUIDELINES.md). To learn/remember common code snippets see
[here](SNIPPETS.md).
Before creating a new topology, make sure that there isn't one already
that does what you need. If nothing is similar, then you may create a
new topology, preferably, using the newest
[template](example-test/test_template.py).
## Installation of Mininet for running tests
Only tested with Ubuntu 16.04 and Ubuntu 18.04 (which uses Mininet 2.2.x)
Instructions are the same for all setups (ie ExaBGP is only used for BGP
tests)
### Installing Mininet Infrastructure:
1. apt-get install mininet
2. apt-get install python-pip
3. apt-get install iproute
4. pip install ipaddr
5. pip install pytest
6. pip install exabgp==3.4.17
(Newer 4.0 version of exabgp is not yet supported)
7. useradd -d /var/run/exabgp/ -s /bin/false exabgp
### Enable Coredumps
Optional, will give better output
1. apt-get install gdb
2. disable apport (which move core files)
Set `enabled=0` in `/etc/default/apport`
3. Update security limits
Add/change `/etc/security/limits.conf` to
#<domain> <type> <item> <value>
* soft core unlimited
root soft core unlimited
* hard core unlimited
root hard core unlimited
4. reboot (for options to take effect)
## FRRouting (FRR) Installation
FRR needs to be installed separatly. It is assume to be configured
like the standard Ubuntu Packages:
- Binaries in /usr/lib/frr
- State Directory /var/run/frr
- Running under user frr, group frr
- vtygroup: frrvty
- config directory: /etc/frr
- For FRR Packages, install the dbg package as well for coredump decoding
No FRR config needs to be done and no FRR daemons should be run ahead
of the test. They are all started as part of the test
#### Manual FRRouting (FRR) build
If you prefer to manually build FRR, then use the following suggested config:
./configure \
--prefix=/usr \
--localstatedir=/var/run/frr \
--sbindir=/usr/lib/frr \
--sysconfdir=/etc/frr \
--enable-vtysh \
--enable-pimd \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--with-pkg-extra-version=-my-manual-build
And create frr User and frrvty group as follows:
addgroup --system --gid 92 frr
addgroup --system --gid 85 frrvty
adduser --system --ingroup frr --home /var/run/frr/ \
--gecos "FRRouting suite" --shell /bin/false frr
usermod -G frrvty frr
## Executing Tests
#### Execute all tests with output to console
py.test -s -v --tb=no
All test_* scripts in subdirectories are detected and executed (unless
disabled in `pytest.ini` file)
`--tb=no` disables the python traceback which might be irrelevant unless the
test script itself is debugged
#### Execute single test
cd test_to_be_run
./test_to_be_run.py
For further options, refer to pytest documentation
Test will set exit code which can be used with `git bisect`
For the simulated topology, see the description in the python file
If you need to clear the mininet setup between tests (if it isn't cleanly
shutdown), then use the `mn -c` command to clean up the environment
#### (Optional) StdErr log from daemos after exit
To enable the reporting of any messages seen on StdErr after the
daemons exit, the following env variable can be set.
export TOPOTESTS_CHECK_STDERR=Yes
(The value doesn't matter at this time. The check is if the env variable
exists or not)
There is no pass/fail on this reporting. The Output will be reported to
the console
export TOPOTESTS_CHECK_MEMLEAK="/home/mydir/memleak_"
This will enable the check and output to console and the writing of
the information to files with the given prefix (followed by testname),
ie `/home/mydir/memcheck_test_bgp_multiview_topo1.txt` in case of a
memory leak.
#### (Optional) Collect Memory Leak Information
FreeRangeRouting processes have the capabilities to report remaining memory
allocations upon exit. To enable the reporting of the memory, define an
enviroment variable `TOPOTESTS_CHECK_MEMLEAK` with the file prefix, ie
export TOPOTESTS_CHECK_MEMLEAK="/home/mydir/memleak_"
This will enable the check and output to console and the writing of
the information to files with the given prefix (followed by testname),
ie `/home/mydir/memcheck_test_bgp_multiview_topo1.txt` in case of a
memory leak.
#### (Optional) Run topotests with GCC AddressSanitizer enabled
Topotests can be run with the GCC AddressSanitizer. It requires GCC 4.8 or
newer. (Ubuntu 16.04 as suggested here is fine with GCC 5 as default)
For more information on AddressSanitizer, see
https://github.com/google/sanitizers/wiki/AddressSanitizer
The checks are done automatically in the library call of `checkRouterRunning`
(ie at beginning of tests when there is a check for all daemons running).
No changes or extra configuration for topotests is required beside compiling
the suite with AddressSanitizer enabled.
If a daemon crashed, then the errorlog is checked for AddressSanitizer
output. If found, then this is added with context (calling test) to
`/tmp/AddressSanitizer.txt` in markdown compatible format.
Compiling for GCC AddressSanitizer requires to use gcc as a linker as well
(instead of ld). Here is a suggest way to compile frr with AddressSanitizer
for `stable/3.0` branch:
git clone https://github.com/FRRouting/frr.git
cd frr
git checkout stable/3.0
./bootstrap.sh
export CC=gcc
export CFLAGS="-O1 -g -fsanitize=address -fno-omit-frame-pointer"
export LD=gcc
export LDFLAGS="-g -fsanitize=address -ldl"
./configure --enable-shared=no \
--prefix=/usr/lib/frr --sysconfdir=/etc/frr \
--localstatedir=/var/run/frr \
--sbindir=/usr/lib/frr --bindir=/usr/lib/frr \
--enable-exampledir=/usr/lib/frr/examples \
--with-moduledir=/usr/lib/frr/modules \
--enable-multipath=0 --enable-rtadv \
--enable-tcp-zebra --enable-fpm --enable-pimd
make
sudo make install
# Create symlink for vtysh, so topotest finds it in /usr/lib/frr
sudo ln -s /usr/lib/frr/vtysh /usr/bin/
and create `frr` user and `frrvty` group as shown above

# Snippets
This document will describe common snippets of code that are frequently
needed to perform some test checks.
## Checking for router / test failures
The following check uses the topogen API to check for software failure
(e.g. zebra died) and/or for errors manually set by `Topogen.set_error()`.
```py
# Get the topology reference
tgen = get_topogen()
# Check for errors in the topology
if tgen.routers_have_failure():
# Skip the test with the topology errors as reason
pytest.skip(tgen.errors)
```
## Checking FRR routers version
This code snippet is usually run after the topology setup to make sure
all routers instantiated in the topology have the correct software
version.
```py
# Get the topology reference
tgen = get_topogen()
# Get the router list
router_list = tgen.routers()
# Run the check for all routers
for router in router_list.values():
if router.has_version('<', '3'):
# Set topology error, so the next tests are skipped
tgen.set_error('unsupported version')
```
A sample of this snippet in a test can be found
[here](ldp-vpls-topo1/test_ldp_vpls_topo1.py).
## Interacting with equipments
You might want to interact with the topology equipments during the tests
and there are different ways to do so.
Notes:
1.
> When using the Topogen API, all the equipments code derive from
> `Topogear` ([lib/topogen.py](lib/topogen.py)). If you feel brave you
> can look by yourself how the abstractions that will be mentioned here
> works.
2.
> When not using the `Topogen` API there is only one way to interact
> with the equipments, which is by calling the `mininet` API functions
> directly to spawn commands.
### Interacting with the Linux sandbox
*Without `Topogen`*
```py
global net
output = net['r1'].cmd('echo "foobar"')
print 'output is: {}'.format(output)
```
---
*With `Topogen`*
```py
tgen = get_topogen()
output = tgen.gears['r1'].run('echo "foobar"')
print 'output is: {}'.format(output)
```
### Interacting with VTYSH
*Without `Topogen`*
```py
global net
output = net['r1'].cmd('vtysh "show ip route" 2>/dev/null')
print 'output is: {}'.format(output)
```
---
*With `Topogen`*
```py
tgen = get_topogen()
output = tgen.gears['r1'].vtysh_cmd("show ip route")
print 'output is: {}'.format(output)
```
`Topogen` also supports sending multiple lines of command:
```py
tgen = get_topogen()
output = tgen.gears['r1'].vtysh_cmd("""
configure terminal
router bgp 10
bgp router-id 10.0.255.1
neighbor 1.2.3.4 remote-as 10
!
router bgp 11
bgp router-id 10.0.255.2
!
""")
print 'output is: {}'.format(output)
```
You might also want to run multiple commands and get only the commands
that failed:
```py
tgen = get_topogen()
output = tgen.gears['r1'].vtysh_multicmd("""
configure terminal
router bgp 10
bgp router-id 10.0.255.1
neighbor 1.2.3.4 remote-as 10
!
router bgp 11
bgp router-id 10.0.255.2
!
""", pretty_output=false)
print 'output is: {}'.format(output)
```
Translating vtysh JSON output into Python structures:
```py
tgen = get_topogen()
json_output = tgen.gears['r1'].vtysh_cmd("show ip route json", isjson=True)
output = json.dumps(json_output, indent=4)
print 'output is: {}'.format(output)
# You can also access the data structure as normal. For example:
# protocol = json_output['1.1.1.1/32']['protocol']
# assert protocol == "ospf", "wrong protocol"
```
*NOTE:* `vtysh_(multi)cmd` is only available for router type of
equipments.
### Invoking `mininet` CLI
*Without `Topogen`*
```py
CLI(net)
```
---
*With `Topogen`*
```py
tgen = get_topogen()
tgen.mininet_cli()
```
## Reading files
Loading a normal text file content in the current directory:
```py
# If you are using Topogen
# CURDIR = CWD
#
# Otherwise find the directory manually:
CURDIR = os.path.dirname(os.path.realpath(__file__))
file_name = '{}/r1/show_ip_route.txt'.format(CURDIR)
file_content = open(file_name).read()
```
Loading JSON from a file:
```py
import json
file_name = '{}/r1/show_ip_route.json'.format(CURDIR)
file_content = json.loads(open(file_name).read())
```
## Comparing JSON output
After obtaining JSON output formated with Python data structures, you
may use it to assert a minimalist schema:
```py
tgen = get_topogen()
json_output = tgen.gears['r1'].vtysh_cmd("show ip route json", isjson=True)
expect = {
'1.1.1.1/32': {
'protocol': 'ospf'
}
}
assertmsg = "route 1.1.1.1/32 was not learned through OSPF"
assert json_cmp(json_output, expect) is None, assertmsg
```
`json_cmp` function description (it might be outdated, you can find the
latest description in the source code at [lib/topotest.py](lib/topotest.py)):
```text
JSON compare function. Receives two parameters:
* `d1`: json value
* `d2`: json subset which we expect
Returns `None` when all keys that `d1` has matches `d2`,
otherwise a string containing what failed.
Note: key absence can be tested by adding a key with value `None`.
```
## Pausing execution
Preferably, choose the `sleep` function that `topotest` provides, as it
prints a notice during the test execution to help debug topology test
execution time.
```py
# Using the topotest sleep
from lib import topotest
topotest.sleep(10, 'waiting 10 seconds for bla')
# or just tell it the time:
# topotest.sleep(10)
# It will print 'Sleeping for 10 seconds'.
# Or you can also use the Python sleep, but it won't show anything
from time import sleep
sleep(5)
```
## `ip route` Linux command as JSON
`topotest` has two helpers implemented that parses the output of
`ip route` commands to JSON. It might simplify your comparison needs by
only needing to provide a Python dictionary.
```py
from lib import topotest
tgen = get_topogen()
routes = topotest.ip4_route(tgen.gears['r1'])
expected = {
'10.0.1.0/24': {},
'10.0.2.0/24': {
'dev': 'r1-eth0'
}
}
assertmsg = "failed to find 10.0.1.0/24 and/or 10.0.2.0/24"
assert json_cmp(routes, expected) is None, assertmsg
```
