registry = QgsSourceSelectProviderRegistry()
registry.addProvider(ConcreteSourceSelectProvider())
registry.addProvider(ConcreteSourceSelectProvider2())
self.assertEqual(['MyTestProviderKey', 'MyName'], [p.name() for p in registry.providers() if p.providerKey().startswith('MyTestProviderKey')])
self.assertTrue(registry.removeProvider(registry.providerByName('MyName')))
self.assertEqual(['MyTestProviderKey'], [p.name() for p in registry.providers() if p.providerKey().startswith('MyTestProviderKey')])
self.assertTrue(registry.removeProvider(registry.providerByName('MyTestProviderKey')))
self.assertEqual([], [p.name() for p in registry.providers() if p.providerKey().startswith('MyTestProviderKey')])示例2: _testRegistry
