What are the differences between Cucumber and JUnit?

Cucumber is a behavior-driven development (BDD) framework, while JUnit is a unit testing framework. Cucumber focuses on testing the behavior of an application from the user's perspective, using plain language, whereas JUnit is more about testing individual components of the code.

Can you give me an example of how to use Cucumber?

Sure! In Cucumber, you write scenarios in Gherkin language. For example:

Feature: User login
  Scenario: Successful login
    Given the user is on the login page
    When the user enters valid credentials
    Then the user should be redirected to the dashboard

How does JUnit handle assertions?

JUnit provides various assertion methods like assertEquals, assertTrue, and assertFalse to verify expected outcomes. For example:

@Test
public void testAddition() {
    assertEquals(5, 2 + 3);
}

Which one should I use for my project?

It depends on your project's needs. If you're focusing on behavior and collaboration with non-technical stakeholders, Cucumber is great. If you need to test individual units of code, JUnit is more suitable.
