certainly! mockito is a popular java library used for unit testing, particularly for mocking objects in order to isolate and test specific parts of your code. in this tutorial, we will focus on testing a void method using mockito.

what is a void method?
a void method is a method that does not return any value. in java, this is defined using the `void` keyword in the method signature. testing void methods often involves verifying the side effects of the method, such as changes to the state of the object or calls to other methods.

setting up mockito
to use mockito, you need to include it in your project. if you are using maven, you can add the following dependency to your `pom.xml`:



example scenario
let’s say we have a simple service class that has a void method for sending notifications. we'll create a test class to verify that the method behaves as expected.

#### step 1: create the service class
here’s a simple `notificationservice` class with a void method `sendnotification`.



and an `emailsender` interface that our service uses to send emails:



#### step 2: create the test class
now, let's write a test class for `notificationservice` using mockito.



explanation of the code
1. **mocks and setup**:
we create a mock instance of `emailsender` using `mockito.mock(emailsender.class)`.
we initialize `notificationservice` with this mock.

2. **test for successful notification**:
in `testsendnotification_callssendemail`, we call the `sendnotification` method with a sample message.
we use `verify` to check that `sendemail` was called exactly once with the correct argument.

3. **test for exception handling**:
in `testsendnotification_withemptymessage_throwsexception`, we check that calling `sendnotification` with an empty message throws an `illegalargumentexception`.

running the tests
you can run the tests using your ide or through the command line with maven:
