affinitic.verifyinterface 0.1

在测试运行器中的简单示例

默认情况下，egg为所有包中的 zope.interface.implements 和 zope.interface.classImplements 启用接口合约验证

>>> write('buildout.cfg',
... """
... [buildout]
... parts =
...     test
...
... [test]
... recipe = zc.recipe.testrunner
... eggs = affinitic.verifyinterface
...        zope.exceptions
... defaults = ['-m', 'module']
... """)

>>> print system(buildout)
Installing test.
...

>>> from os.path import join
>>> print system(join('bin', 'test')),

Running zope.testing.testrunner.layer.UnitTests tests:
  Set up zope.testing.testrunner.layer.UnitTests in 0.000 seconds.
  Ran 2 tests with 0 failures and 0 errors in 0.000 seconds.
Tearing down left over layers:
  Tear down zope.testing.testrunner.layer.UnitTests in 0.000 seconds.

限制验证

但你可以限制需要执行此验证的包（有时你不在乎你依赖的包是否正确实现了接口）。

这通过添加环境变量 verifyinterface 来完成，其中指定了你要验证接口的包/模块（通常用n分隔）。

以下是一个简单示例，我只希望对模块1使用的接口的错误实现发出警告

>>> write('buildout.cfg',
... """
... [buildout]
... parts =
...     test
...
... [test]
... recipe = zc.recipe.testrunner
... eggs = affinitic.verifyinterface
...        zope.exceptions
... defaults = ['-m', 'module']
... environment = testenv
...
... [testenv]
... verifyinterface = affinitic.verifyinterface.tests.test_module1
... """)

>>> print system(buildout)
Uninstalling test.

>>> from os.path import join
