Do you know any types of testing?

Yes, I know.

Main types of testing:

• Functional testing:

  • Smoke Testing
  • Sanity Testing
  • Integration Testing
  • System Testing
  • Regression Testing
  • Acceptance Testing - including alpha and beta testing.

• Non-functional testing:

  • Performance Testing - includes load, stress, and volume testing.
  • Security Testing
  • Usability Testing
  • Compatibility Testing
  • Reliability Testing
  • Accessibility Testing
  • Localization Testing
  • Internationalization Testing

• Change-related testing:

  • Smoke Testing
  • Regression Testing

• Structural testing (based on code):

  • Unit Testing
  • White Box Testing

• Experience-based testing:

  • Exploratory Testing
  • Checklist-based Testing
  • Scenario-based Testing

Examples of application of some types:

Testing Type	Brief Description	When Applied
Smoke Testing	Checking main functions after build or deployment.	Each new build.
Regression Testing	Checking that changes did not introduce new defects into existing functionality.	After each change or defect fix.
Load Testing	Checking system behavior under expected load.	Before commissioning, during architecture changes.
Unit Testing	Testing individual components or code modules.	During development, by developers.

In test automation, we most often automate regression tests, integration tests, and sometimes performance and security tests.

// Example of Unit tests (JUnit)
public class Calculator {
    public int add(int a, int b) {
        return a + b;
    }
}

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;

class CalculatorTest {
    @Test
    void testAdd() {
        Calculator calculator = new Calculator();
        assertEquals(5, calculator.add(2, 3), "Adding 2 and 3 should be 5");
    }
}

# Example of Selenium Webdriver test (Python)
from selenium import webdriver

driver = webdriver.Chrome()
driver.get("https://www.google.com")
print(driver.title)
driver.quit()
