pyogctest

pyogctest is a Python tool to run OGC test suites from your terminal. This is done by using the REST API provided by Teamengine. Then the resulting XML report is parsed and displayed to be humanly readable "à la" pytest (as much as possible).

pyogctest has been developed and tested with QGIS Server in mind thanks to QGIS.org. However, there's nothing specific to QGIS Server itself (excepted for the HTML report CSS theme), so it should work with other map servers too (while not tested).

For now, only the next test suites are supported:

• WMS 1.3.0
• OGC API FEATURE 1.0

Install

To install Python dependencies:

$ git clone https://github.com/pblottiere/pyogctest
$ cd pyogctest
$ virtualenv venv
$ source venv/bin/activate
(venv) $ pip install poetry
(venv) $ poetry install

Some system dependencies are also necessary:

• docker because Teamengine is used through Docker images provided on Dockerhub.
• xmlstarlet to convert a XML document into a HTML report (useful when the html format option is activated)

Usage

pyogctest allows to run OGC tests on a map server instance, so the first thing you need is an URL pointing to the map server itself. In this documentation, we're going to use an online instance of QGIS Server (the one used for official certifications).

To run the WMS 1.3.0 test suites:

$ ./pyogctest.py -s wms130 -u http://qgis4.qgis.org:8080/certification_qgisserver_master

In case of failure, a descriptive message is displayed for all failing tests:

Verbose

If you want more details about tests, you can use the -v option when the format is prompt:

$ ./pyogctest.py -s wms130 -v -u http://qgis4.qgis.org:8080/certification_qgisserver_master
======================================== OGC test session starts =========================================
testsuite: WMS 1.3.0

data-independent::basic_elements::param-rules::extra-GetCapabilities-param PASSED
data-independent::basic_elements::version-negotiation::negotiate-no-version PASSED
...

Regex

We cannot control tests which are genuinely executed by Teamengine, but we can filter the report. A -r option is available when the prompt format is activated. It's not a "real" regular expression parameter, only a simple pattern matching:

$ ./pyogctest.py -r transparent -s wms130 -v -u http://qgis4.qgis.org:8080/certification_qgisserver_master
======================================== OGC test session starts =========================================

data-independent::getmap::transparent::transparent-false PASSED
data-independent::getmap::transparent::transparent-default PASSED
data-independent::getmap::transparent::transparent-opaque-layer PASSED
basic::getmap::transparent::transparent-true PASSED

======================================== 183 passed in 74 seconds ========================================

HTML report

By default the output format is prompt but you can also the the -f html option to generate a HTML report. In this case, you can control the next parameters:

• -o for the output directory with a QGIS CSS theme file
• -b for the branch name to use in the report
• -c for the commit number to use in the report

Docker binding port

The default binding port for the Docker container is 8081 but you may have an error if this port is already in use on your system:

$ ./pyogctest.py -s wms130 http://qgis4.qgis.org:8080/certification_qgisserver_master
docker.errors.APIError: 500 Server Error: Internal Server Error ("driver failed programming external connectivity on endpoint pyogctest: Error starting userland proxy: listen tcp 0.0.0.0:8081: bind: address already in use")

In this case you have to use the -p option to use another port:

$ ./pyogctest.py -s wms130 -p 8088 -u http://qgis4.qgis.org:8080/certification_qgisserver_master

Help

To take a look at all available options, you can use the -h parameter:

$ ./pyogctest.py --help
usage: pyogctest.py [-h] [-u URL] [-p PORT] [-n NETWORK] [-d] [-w] [-x] [-f {prompt,html}] [-s {wms130}] [-r REGEX] [-v] [-o OUTPUT] [-c COMMIT] [-b BRANCH]

optional arguments:
  -h, --help            show this help message and exit
  -u URL, --url URL     URL

  -s {wms130}, --suite {wms130,ogcapif}
                        Test suite (default: 'wms130')
