Invocation
==========
Test multiples hosts
~~~~~~~~~~~~~~~~~~~~
By default Testinfra launch tests on local machine, but you can also
test remotes systems using `paramiko <https://www.paramiko.org>`_ (a
ssh implementation in python)::
$ pip install paramiko
$ pytest -v --hosts=localhost,root@webserver:2222 test_myinfra.py
====================== test session starts ======================
platform linux -- Python 2.7.3 -- py-1.4.26 -- pytest-2.6.4
plugins: testinfra
collected 3 items
test_myinfra.py::test_passwd_file[localhost] PASSED
test_myinfra.py::test_nginx_is_installed[localhost] PASSED
test_myinfra.py::test_nginx_running_and_enabled[localhost] PASSED
test_myinfra.py::test_passwd_file[root@webserver:2222] PASSED
test_myinfra.py::test_nginx_is_installed[root@webserver:2222] PASSED
test_myinfra.py::test_nginx_running_and_enabled[root@webserver:2222] PASSED
=================== 6 passed in 8.49 seconds ====================
You can also set hosts per test module::
testinfra_hosts = ["localhost", "root@webserver:2222"]
def test_foo(host):
[....]
Parallel execution
~~~~~~~~~~~~~~~~~~
If you have a lot of tests, you can use the pytest-xdist_ plugin to run tests using multiples process::
$ pip install pytest-xdist
# Launch tests using 3 processes
$ pytest -n 3 -v --host=web1,web2,web3,web4,web5,web6 test_myinfra.py
Advanced invocation
~~~~~~~~~~~~~~~~~~~
::
# Test recursively all test files (starting with `test_`) in current directory
$ pytest
# Filter function/hosts with pytest -k option
$ pytest --hosts=webserver,dnsserver -k webserver -k nginx
For more usages and features, see the Pytest_ documentation.
