Debugger

Testing
Conceptos Fundamentales

¿Qué es un Debugger?

Herramienta de desarrollo que permite ejecutar código paso a paso, inspeccionar variables y analizar el flujo de ejecución para identificar y resolver errores.

Funcionamiento Básico

Ejecución Controlada: Pausa la ejecución en puntos específicos
Inspección de Estado: Acceso a variables y memoria en tiempo de ejecución
Análisis de Flujo: Seguimiento del camino de ejecución del programa

Componentes del Debugger

Call Stack

Seguimiento de Llamadas: Muestra la pila de ejecución de funciones/métodos
Navegación Jerárquica: Permite ver qué función llamó a la actual
Contexto de Ejecución: Cada frame muestra variables locales y parámetros

Breakpoints

Puntos de Interrupción: Marcadores que pausan la ejecución
Condicionales: Se activan solo cuando se cumple una condición específica
Temporales: Se eliminan automáticamente después de activarse

Inspección de Variables

Variables Locales: Valores en el contexto actual de ejecución
Variables Globales: Estado del ámbito global
Watch Expressions: Expresiones personalizadas para monitorear

Step Through

Step Into: Entra en la función/método actual
Step Over: Ejecuta la línea actual sin entrar en funciones
Step Out: Sale de la función actual y continúa
Continue: Reanuda la ejecución hasta el próximo breakpoint

Debugging en JavaScript

Herramientas Específicas

// Console debugging
console.log('Variable value:', variable);
console.table(arrayOfObjects);
console.trace('Execution trace');

// Debugger statement
function problematicFunction() {
    debugger; // Pausa la ejecución si el debugger está abierto
    // código problemático
}

Chrome DevTools

// Breakpoints avanzados
// - Line breakpoints
// - Conditional breakpoints  
// - DOM breakpoints
// - Event listener breakpoints
// - XHR/fetch breakpoints

// Ejemplo de watch expressions
const user = { name: 'John', age: 30 };
// Watch: user.name
// Watch: JSON.stringify(user)

Node.js Debugging

# Iniciar con inspector
node --inspect app.js
node --inspect-brk app.js # Pausa al inicio

# Con nodemon para desarrollo
nodemon --inspect app.js

Diferencias entre Lenguajes

JavaScript vs Java

// Java debugging - más estructurado
public class DebugExample {
    public static void main(String[] args) {
        int result = calculate(5, 3);
        System.out.println("Result: " + result);
    }
    public static int calculate(int a, int b) {
        // Punto de interrupción tradicional
        int sum = a + b;
        return sum * 2;
    }
}

Características Comparativas

JavaScript: Dinámico, tipado débil, debugging en navegador y Node.js
Java: Tipado fuerte, debugging con IDEs robustas (IntelliJ, Eclipse)
Python: Debugging interactivo, tipado dinámico
C++: Debugging a nivel de memoria, pointers, más complejo

Técnicas Avanzadas de Debugging

Conditional Breakpoints

// Solo se activa cuando se cumple la condición
function processUsers(users) {
    for (let user of users) {
        // Breakpoint condicional: user.age > 65
        if (user.age > 65) {
            processSenior(user);
        }
    }
}

Watch Expressions Avanzadas

const data = {
    users: [
        { id: 1, active: true },
        { id: 2, active: false }
    ]
};

// Watch expressions útiles:
// data.users.filter(u => u.active).length
// data.users.map(u => u.id)
// JSON.stringify(data, null, 2)

Call Stack Analysis

function a() {
    b();
}

function b() {
    c();
}

function c() {
    console.trace(); // Muestra call stack completo
    throw new Error('Debug this!');
}

a();

Debugging en Diferentes Entornos

Frontend (Browser)

Chrome DevTools: Console, Sources, Network tabs
Firefox Developer Tools: Similar funcionalidad
Browser Extensions: React DevTools, Vue DevTools

Backend (Node.js)

// Debugging remoto
const inspector = require('inspector');
inspector.open(9229, '0.0.0.0', true);

// Logging estructurado
const debug = require('debug')('app:server');
debug('Server started on port %d', 3000);
