Mock Dio flutter

Mockito is a mocking framework for unit tests written in Java . It is an open source framework available at github. You can use Mockito with JUnit to create and use mock objects during unit testing. To start using Mockito, download the JAR file and place it in your project class.

JUnit is the Java library used to write tests (offers support for running tests and different extra helpers – like setup and teardown methods, test sets etc.). Mockito is a library that enables writing tests using the mocking approach .

The Mockito. mock() method allows us to create a mock object of a class or an interface . We can then use the mock to stub return values for its methods and verify if they were called. We don’t need to do anything else to this method before we can use it.
