You can have a look of this library in this blog post, showing 6 simple examples of Mockito usage.
A short example:
@Test
public void iteratorWillReturnHelloWorld(){
//arrange
Iterator i = mock(Iterator.class);
when(i.next()).thenReturn("Hello").thenReturn("World");
//act
String result = i.next() + " " + i.next();
//assert
assertEquals("Hello World", result);
}
Edit regarding your requirements:
It seems that Mockito runs quite well on Java 1.4 and JUnit 3, as stated in this blog post.
The same example as above, but for Java 1.4:
public void testIteratorWillReturnHelloWorld(){
//arrange
Iterator i = Mockito.mock(Iterator.class);
Mockito.when(i.next()).thenReturn("Hello").thenReturn("World");
//act
String result = i.next() + " " + i.next();
//assert
assertEquals("Hello World", result);
}

The rapid shift in the use of technology has impacted testing and quality assurance significantly, especially around the cloud adoption of agile development methodologies. With this, the increasing importance of quality and automation testing has risen enough to deliver quality work.
The fact is not alien to us anymore that cross browser testing is imperative to enhance your application’s user experience. Enhanced knowledge of popular and highly acclaimed testing frameworks goes a long way in developing a new app. It holds more significance if you are a full-stack developer or expert programmer.
Unit testing is typically software testing within the developer domain. As the QA role expands in DevOps, QAOps, DesignOps, or within an Agile team, QA testers often find themselves creating unit tests. QA testers may create unit tests within the code using a specified unit testing tool, or independently using a variety of methods.
Lack of training is something that creates a major roadblock for a tester. Often, testers working in an organization are all of a sudden forced to learn a new framework or an automation tool whenever a new project demands it. You may be overwhelmed on how to learn test automation, where to start from and how to master test automation for web applications, and mobile applications on a new technology so soon.
Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
