Despite its complex architecture, AutoFixture exposes a very simple programming interface wrapped by the
Developers can use its parameterless constructor to obtain an instance based on the default configuration. This configuration includes the wiring for the different parts of the framework and configurations for the most common types of the Base Class Library.
IFixtureinterface. The properties and methods of this interface are used to configure the specimens generation and the creation of the specimens via AutoFixture's fluent API.
IFixtureexposes the following properties
Behaviors: a list of decorators whose execution wraps the execution of each builder
Customizations: a list of customizations that are used to create values before using default builders
ResidueCollectors: a collection of builders to be used as fallback in case no default builder nor customization was able to serve the request
OmitAutoProperties: specifies whether properties should receive a value, default is
RepeatCount: specifies the amount of items to be added when creating a collection, default is
Build<T>(): initiates the creation of an instance of the given type ignoring all prior customizations
Customize<T>(): customizes the creation algorithm for all instances of a given type
Customize(): applies a customization to the current
On top of the methods above, several extension methods are defined on the
IFixturetype. These extension methods are all built on the basic operations exposed by
IFixture. The most important ones will be presented in depth later on.
