pywcmp

WMO核心元数据配置文件测试套件

pywcmp为WMO WIS核心元数据配置文件（WCMP）提供验证和质量评估功能。

• 针对WCMP2（草案）进行验证，特别是附件A：一致性类抽象测试套件，实现针对ATS的可执行测试套件
• 针对WCMP关键性能指标进行质量评估

安装

pip

从PyPI安装最新稳定版本。

pip3 install pywcmp

从源代码

安装最新开发版本。

python3 -m venv pywcmp
cd pywcmp
. bin/activate

cd pywcmp
pip3 install -r requirements.txt
python3 setup.py install

运行

从命令行

# fetch version
pywcmp --version

# sync supporting configuration bundle (schemas, topics, etc.)
pywcmp bundle sync

# abstract test suite

# validate WCMP2 metadata against abstract test suite (file on disk)
pywcmp ets validate /path/to/file.json

# validate WCMP2 metadata against abstract test suite (URL)
pywcmp ets validate https://example.org/path/to/file.json

# validate WCMP2 metadata against abstract test suite (URL), but turn JSON Schema validation off
pywcmp ets validate https://example.org/path/to/file.json --no-fail-on-schema-validation

# adjust debugging messages (CRITICAL, ERROR, WARNING, INFO, DEBUG) to stdout
pywcmp ets validate https://example.org/path/to/file.json --verbosity DEBUG

# write results to logfile
pywcmp ets validate https://example.org/path/to/file.json --verbosity DEBUG --logfile /tmp/foo.txt

# key performance indicators

# all key performance indicators at once
pywcmp kpi validate https://example.org/path/to/file.json --verbosity DEBUG

# all key performance indicators at once, but turn ETS validation off
pywcmp kpi validate https://example.org/path/to/file.json --no-fail-on-ets --verbosity DEBUG

# all key performance indicators at once, in summary
pywcmp kpi validate https://example.org/path/to/file.json --verbosity DEBUG --summary

# selected key performance indicator
pywcmp kpi validate --kpi title /path/to/file.json -v INFO

使用API

>>> # test a file on disk
>>> import json
>>> from pywcmp.wcmp2.ets import WMOCoreMetadataProfileTestSuite2
>>> with open('/path/to/file.json') as fh:
...     data = json.load(fh)
>>> # test ETS
>>> ts = WMOCoreMetadataProfileTestSuite2(datal)
>>> ts.run_tests()  # raises ValueError error stack on exception
>>> # test a URL
>>> from urllib2 import urlopen
>>> from StringIO import StringIO
>>> content = StringIO(urlopen('https://....').read())
>>> data = json.loads(content)
>>> ts = WMOCoreMetadataProfileTestSuite2(data)
>>> ts.run_tests()  # raises ValueError error stack on exception
>>> # handle pywcmp.errors.TestSuiteError
>>> # pywcmp.errors.TestSuiteError.errors is a list of errors
>>> try:
...    ts.run_tests()
... except pywcmp.errors.TestSuiteError as err:
...    print('\n'.join(err.errors))
>>> ...
>>> # test KPI
>>> from pywcmp.kpi import WMOCoreMetadataProfileKeyPerformanceIndicators
>>> kpis = WMOCoreMetadataProfileKeyPerformanceIndicators(data)
>>> results = kpis.evaluate()
>>> results['summary']
