What methods have you used to automate testing in your last project?

In my last project, test automation was implemented using the following methods:

• Unit tests with frameworks (such as JUnit for Java or Jest for JavaScript) to test individual modules.
• Integration tests to verify interactions between components.
• UI test automation using Selenium WebDriver, which allowed testing user scenarios.
• CI/CD integration, where tests were run automatically on each commit, providing quick feedback.
• Use of Mock objects and stubs to isolate tested components.

Example of a simple unit test in Java with JUnit:

import static org.junit.Assert.*;
import org.junit.Test;

public class CalculatorTest {
    @Test
    public void testAdd() {
        Calculator calc = new Calculator();
        assertEquals(5, calc.add(2, 3));
    }
}
