背景: 项目中有多个测试用例,测试用例使用yaml的配置文件,各个测试用例的yaml配置文件中有一些共有的属性,
把这些共有的属性抽取出来放在一个yaml文件中,问题来了:如何在测试用例的Yaml文件引用这些共享的Yaml文件:
测试用例的yaml文件:document.yml
languages:
- Ruby
- Perl
- Python
websites:
YAML: yaml.org
Ruby: ruby-lang.org
Python: python.org
Perl: use.perl.org
test: !include doc01.yml
共享的yaml文件: doc01.yml
demo01:
- Ruby
python实现:
import yaml
import os
def yaml_include(loader, node):
# Get the path out of the yaml file
file_name = os.path.join(os.path.dirname(loader.name), node.value)
with file(file_name) as inputfile:
return yaml.load(inputfile)
yaml.add_constructor("!include", yaml_include)
stream = file('document.yml', 'r')
print yaml.dump(yaml.load(stream))
打印结果:
languages: [Ruby, Perl, Python]
test:
demo01: [Ruby]
websites: {Perl: use.perl.org, Python: python.org, Ruby: ruby-lang.org, YAML: yaml.org}
