How is unit testing used in middleware testing?


Asked by Maci Solomon on Dec 14, 2021 FAQ



Using Middleware unit testing you can test parts of code which is placed in program. You can also get more detail result of your testing. Using these you can customize data structures, like HttpContext, directly within the test.
Besides,
As we know Middleware is a component that is used in the application pipeline to handle requests and responses which can also help perform pre and post-operation within the API pipeline. While you add these customizations in the form pre or post request or response, you may want to Unit Test these components the robust code.
Keeping this in consideration, Middleware is often tested in isolation with Test Server. It allows you to instantiate an app pipeline containing only the components that you simply got to test. Requests are sent in-memory instead of being serialized over the network. Exceptions within the middleware can flow directly back to the calling test.
And,
– Developers significantly make use of Unit test frameworks or unit testing tools for developing automated test cases. – While executing the test cases, the unit test frameworks help to flag and report the failed test cases. Also, based on the failures in the test cases, the unit test frameworks help to stop the related testing.
Just so,
Although not a common practice, unit testing middleware ensures that we have a complete test suite. Also, it saves us time in that we don’t have to build out a whole feature, and then write feature tests just to be sure that some piece of middleware works as expected.
