XP is an Agile methodology that emphasizes software quality and customer satisfaction. It involves practices such as test-driven development (TDD), continuous integration (CI), and pair programming. The team works closely with the customer to ensure that the software meets their needs.
Sample code snippet for XP:
public class Test {
public void testAdd() {
Calculator calc = new Calculator();
int result = calc.add(2, 3);
assertEquals(5, result);
}
}
public class Calculator {
public int add(int x, int y) {
return x + y;
}
}
public class ContinuousIntegration {
public void build() {
// Compile and run tests
// Deploy to staging environment
// Send notification to team
}
}
public class PairProgramming {
public void pairProgram()
