A Python implementation of the test suite for WMO Core Metadata Profile

Project description

Build Status

WMO Core Metadata Profile Test Suite

This library implements validation against WMO Core Metadata Profile 1.3, specifically Part 2, Section 2.

Installation

python3 -m venv pywcmp
cd pywcmp
. bin/activate
git clone https://github.com/wmo-im/pywcmp.git
cd pywcmp
pip3 install -r requirements.txt
python3 setup.py build
python3 setup.py install

Running

From command line:

# fetch version
pywcmp --version

# abstract test suite

# validate metadata against abstract test suite (file on disk)
pywcmp ats validate --file /path/to/file.xml

# validate metadata against abstract test suite (URL)
pywcmp ats validate --url http://example.org/path/to/file.xml

# adjust debugging messages (CRITICAL, ERROR, WARNING, INFO, DEBUG) to stdout
pywcmp ats validate --url http://example.org/path/to/file.xml --verbosity DEBUG

# write results to logfile
pywcmp ats validate --url http://example.org/path/to/file.xml --verbosity DEBUG --logfile /tmp/foo.txt

# key performance indicators # note: running KPIs automatically runs the ats
pywcmp kpi validate --url http://example.org/path/to/file.xml --verbosity DEBUG

Using the API

# test a file on disk
>>> from lxml import etree
>>> from pywcmp.ats import ats
>>> exml = etree.parse('/path/to/file.xml')
>>> ts = ats.WMOCoreMetadataProfileTestSuite13(exml)
>>> ts.run_tests()  # raises ValueError error stack on exception
# test a URL
>>> from urllib2 import urlopen
>>> from StringIO import StringIO
>>> content = StringIO(urlopen('http://....').read())
>>> exml = etree.parse(content)
>>> ts = ats.WMOCoreMetadataProfileTestSuite13(exml)
>>> ts.run_tests()  # raises ValueError error stack on exception
# handle ats.TestSuiteError
# ats.TestSuiteError.errors is a list of errors
>>> try:
...    ts.run_tests()
... except ats.TestSuiteError as err:
...    print('\n'.join(err.errors))
>>> ...
>>> from pywcmp.kpi import WMOCoreMetadataProfileKeyPerformanceIndicators
>>> kpis = WMOCoreMetadataProfileKeyPerformanceIndicators(exml)
>>> kpis['totals']
