This repository contains

  • a server to test scrapers against
  • tests to test the server

The package works under Python 2 and 3.

You can view the live docker instance at http://scrst.quelltext.eu/

Installation

Using pip, you can install all dependencies like this:

.. code:: shell

pip install --user schul_cloud_resources_server_tests

When you are done, you can import the package.

.. code:: Python

import schul_cloud_resources_server_tests

Installation for Development

If you want to work on the module, you need to install it differently.
If you set it up for development, you can add new tests and features.

First, you need to have git installed. Then, clone the repository:

.. code:: shell

git clone https://github.com/schul-cloud/schul_cloud_resources_server_tests.git
cd schul_cloud_resources_server_tests

If you have pip installed, you can now install the packages:

.. code:: shell

pip install --user -r requirements.txt pip-tools==1.6.5

Now, as long as you are in the schul_cloud_resources_server_tests folder, you can run the commands as mentioned below.
Additionally, you can use git to create pull-requests with your edited code.

Usage

This section describes how to use the server and the tests.

Server


You can find the API_ definition.
The server serves according to the API_.
It verifies the input and output for correctness.

To start the server, run

.. code:: shell

    python -m schul_cloud_resources_server_tests.app

The server should appear at http://localhost:8080/v1.

Tests
~~~~~

You always test against the running server.
**Tests may delete everyting you can reach.**
If you test the running server, make sure to authenticate in a way that does not destroy the data you want to keep.

.. code:: shell

    python -m schul_cloud_resources_server_tests.tests --url=http://localhost:8080/v1/

http://localhost:8080/v1/ is the default url.

Steps for Implementation
~~~~~~~~~~~~~~~~~~

If you want to implement your server you can follow the TDD steps to implement
one test after the other.

.. code:: shell

python -m schul_cloud_resources_server_tests.tests -m step1
python -m schul_cloud_resources_server_tests.tests -m step2
python -m schul_cloud_resources_server_tests.tests -m step3
...
  • step1 runs the first test
  • step2 runs the first and the second test
  • step3 runs the first, second and third test
  • ...

You can run a single test with

.. code:: shell

python -m schul_cloud_resources_server_tests.tests -m step3only

Test Authentication


The test server supports api key authentication and basic authentication.
If you test authentication over the internet.
Use https to protect the secrets.
Thus, an example test call to your api could look like this:

.. code:: Python

    python -m schul_cloud_resources_server_tests.tests  \
           --url=https://url.to/your/server               \
           --noauth=false --basic=username:password

If you have an api key, you can test that the server works.

.. code:: Python

    python -m schul_cloud_resources_server_tests.tests   \
           --url=http://url.to/your/server                \
           --noauth=false --apikey=apikey

By default the test server accepts authentication with several credentials

- no authentication
- basic:

  - user ``valid1@schul-cloud.org`` password ``123abc``
  - user ``valid2@schul-cloud.org`` password ``supersecure``
- api key: ``abcdefghijklmn`` for the user ``valid1@schul-cloud.org``.
  The client does not send the user name to the server.

To test these, you can add the ``--basic`` and ``--apikey``
parameters several times to the tests.
The ``--noauth=true`` parameter is default.
If the api only accepts authenticated requests, set ``--noauth=false``.

.. code:: Python

    python -m schul_cloud_resources_server_tests.tests    \
           --basic=valid1@schul-cloud.org:123abc           \
           --basic=valid2@schul-cloud.org:supersecure      \
           --apikey=valid1@schul-cloud.org:abcdefghijklmn  \
           --noauth=true

All tests are run with the different authentication options.
If we have several ways to authenticate, the tests test if the user sees the other users' data.

It is assumed, that adding ``invalid`` to the password,
user name and api key will make it invalid.
Tests use the invalid credentials to test the server behavior in rejected cases.

Example Travis Configuration
----------------------------

If you want to implement a crawler or server, you can use Travis-CI to test
it.
An example travis configuration can be found in the `test-example
<https://github.com/schul-cloud/schul_cloud_resources_server_tests/blob/test-example/.travis.yml>`__ branch.
You can view the `output
<https://travis-ci.org/schul-cloud/schul_cloud_resources_server_tests/branches>`__
The configuration is generic.
It will run under any other language you configure.

Usage in Crawler
----------------

The `url-crawler <https://github.com/schul-cloud/url-crawler#readme>`__ uses the test server to test synchronization.

Use the server in pytest
------------------------

You can use the sever in Python tests.
There are fixtures available that start and stop the server.

.. code:: Python

    from schul_cloud_resources_server_tests.tests.fixtures import *

    def test_pytest(resources_server):
        """pytest using the server"""

The following attributes are available:

- ``resources_server.url`` The url of the server.
- ``resources_server.api`` A ``schul_cloud_resources_api_v1.ResourcesApi`` object connected to the server.
- ``resources_server.get_resources()`` A function to return a list of resources on the server.

For more information, see the module ``schul_cloud_resources_server_tests.tests.fixtures``.
You can add support for more test frameworks.

Docker
------

You can build the this image with the following docker command:

.. code:: shell

    docker build -t schulcloud/schul_cloud_resources_server_tests .

Or you can pull the docker container and run it.

.. code:: shell

    docker run schulcloud/schul_cloud_resources_server_tests

This starts the server at the port 8080 as in the examples above.

Docker-Compose

There is a docker-compose.yml file, so you can use the docker-compose command.
The server will be available at http://localhost:80/v1
It uses a memory limit of 60MB.


You can edit this document on Github <https://github.com/schul-cloud/schul_cloud_resources_server_tests/blob/master/README.rst#readme>
