This article will explain in detail how the default implementation of xunit is, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Default implementation

To make it easy for you to get started quickly, every behavior component and structure component added in the editor has a default implementation. All of these behavior components have a common default implementation:

DefaultUnitImpl

DefaultUnitImpl provides a static String constant that can be recognized and displayed by the editor by defining the beginning of the PROP_KEY. If the behavior component is DefaultUnitImpl, the editor displays its property values as follows:

The default features of DefaultUnitImpl include:

Default Validator and Locator implementation

Allows you to specify validate or locate according to a specific field in Context. EvaluateField needs to be specified. When running, first match the getter that conforms to the java bean naming convention according to the given field name, and if it cannot be found, directly access the corresponding attributes in the Context according to the field name.

Allows you to specify to call a specific method in Context to do validate or locate. EvaluateMethod needs to be specified. At run time, the method in the corresponding Context is called according to the given name

Set the default value of validate

The validateDefault property needs to be specified. At run time, this value is returned directly when the property or method required by validate is not specified.

Display specific information as Processor and Converter display the given information

The showMessage property needs to be specified. The runtime displays the given content directly

Show application level properties

The showApplicationProperties property needs to be specified. Property names are separated by ",".

If the user provides a well-defined Context, this default implementation provides the functionality of Valiator and Locator. This is equivalent to covering 50% of the functionality of the four behavioral components, including Processor and Converter. Users can only focus on the development of Processor and Converter, thus reducing the workload and improving the development efficiency.

On how the default implementation of xunit is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
