spid-sp-test 0.5.0

SAML2 SPID Service Provider validation tool that can be run from the command line

spid-sp-test

spid-sp-test is a SAML2 SPID Service Provider validation tool that can be executed from the command line. This tool was born by separating the test library already present in spid-saml-check.

Features

spid-sp-test is:

• extremely faster in execution time than spid-saml-check
• extremely easy to setup
• able to test a SAML2 SPID Metadata file
• able to test a SAML2 SPID AuthnRequest
• able to test ACS behaviour, how a SP reply to a SAML2 Response
• able to dump the response sent to an ACS and the HTML of the SP's response
• able to handle Attributes to send in Responses or test configurations of the Responses via json configuration files
• integrable in CI
• able to export a detailed report in json format, in stdout or in a file.

Setup

apt install libxml2-dev libxmlsec1-dev libxmlsec1-openssl
pip install spid-sp-test --upgrade --no-cache

Overview

spid-sp-test can test a SP metadata file, you just have to give the Metadata URL, if http/http or file, eg: file://path/to/metadata.xml. At the same way it can test an Authentication Request.

In a different manner spid-sp-test can send a huge numer of fake SAML Response, for each of them it needs to tigger a real Authentication Request to the target SP.

If you want to test also the Response, you must give the spid-sp-test fake idp metadata file to the target SP. Get fake IdP metadata and copy it to your SP metadatastore folder

spid_sp_test --idp-metadata > /path/to/spid-django/example/spid_config/metadata/spid-sp-test.xml

To get spid-sp-test in a CI you have to:

• configure an example project to your application
• use the spid-sp-test fake idp metadata, configure it in your application and execute the example project, with its development server in background
• launch the spid-sp-test commands

An example of CI is here

Examples

Run spid_sp_test -h for inline documentation.

  --html-path HTML_PATH, -hp HTML_PATH
                        Only works with Response tests activated. Path where the html response pages will be dumped after by the SP
  --exit-zero, -ez      exit with 0 even if tests fails

Given a metadata file and a authn file (see tests/metadata and tests/authn for example) export all the test response without sending them to SP:

spid_sp_test --metadata-url file://tests/metadata/spid-django-other.xml --authn-url file://tests/authn/spid_django_post.html --extra --debug ERROR -tr -nsr

Test Responses and html dumps

By enabling the response dump with the --html-path HTML_PATH option, you will get N html files (page of your SP) as follows:

• test description, commented
• SAML Response sent, commented
• SP html page, with absolute src and href (god bless lxml)

Here an example of 1_True.html, where 1 is the test name and True is the status.

Extending tests

spid-sp-test offers the possibility to extend and configure the tests to be performed. The user can:

• customize the test suite to run by configuring a json file similar to tests/example.test-suite.json and passing this as an argument with --test-jsons option. More than one json file can be entered by separating it by a space

• customize the attributes to be returned by configuring these in a json file similar to example/example.attributes.json and passing this with the --attr-json option

• customize xml templates to be used in tests, indicating them in each test entry in the configuration file configured via --test-jsons and also the templates directory with the option --template-path. The templates are Jinja2 powered, so it's possible to extend src/spid_sp_test/responses/templates/base.xml with our preferred values

Looking at src/spid_sp_test/responses/settings.py or tests/example.test-suite.json we found that every test have a response attribute. Each element configured in would overload the value that will be rendered in the template. Each template can load these variable from its template context or use which ones was statically defined in it.
