31-Aug-2023To create custom expectations in .NET Core, you can use the
IAsyncExpectation
interface. This interface provides a way to define custom expectations for asynchronous operations.To create a custom expectation, you need to inherit from the
IAsyncExpectation
interface and implement theHandle
method. TheHandle
method is called when the asynchronous operation is complete.In the
Handle
method, you can check the outcome of the asynchronous operation and raise an error if the outcome is not as expected.Here is an example of how to create a custom expectation that checks the status code of an HTTP response:
C#
This custom expectation will check the status code of the HTTP response and raise an error if the status code is not equal to the expected status code.
You can consider creating custom expectations when you need to check the outcome of an asynchronous operation in a specific way. For example, you might need to check the status code of an HTTP response, or the value of a property in a JSON response.
Here are some additional things to consider when creating custom expectations:
