Published: 2023-09-04 00:36:09

**_Manual Testing_**
Manual testing is a software testing method where testers execute test cases and verify the software functionality, usability, and other features manually, without using any automation tools or scripts. In manual testing, human testers play a vital role in identifying defects, verifying whether the software meets the specified requirements, and ensuring that it functions as expected.

**_Benefits of Manual Testing_**

-  Manual testing allows testers to interact with the software just like end-users would which gives insights to the actual user experience and identifying usability issues which are all  unnoticed during automated testing.
-  Human testers have the ability to explore the software in an ad hoc manner, and identifying the  unexpected issues and scenarios that are all not covered by predefined test cases.
- Manual Testing is highly effective on Non Functional testing in a way of user experience and interface which are all not easy in automated testing.
- Manual testing is well-suited for  complex scenarios testing which involves multiple variables or interactions that are difficult to automated testing
- Manual Testers provide early feedback on software usability, feel, look and other aspects of non functionality of application which are not easy in automation.

**_Drawbacks of Manual Testing_**

- Manual testing is highly  time-consuming and requires large amount of  human resources to execute test cases,  efficiency of manual testing on large  scale or repetitive task is very low.
- Human errors occurs during  the  execution of  test cases, potentially leading to inaccurate results or missed defects.
- Investment of time & money is so high on Manual Testing like hiring the skilled professional requires more time & cost during the product making
- Regression testing, which involves repeatedly executing the same test cases which become monotonous and error-prone for testers.
- The manual documentation of test cases, results, and defects are time-consuming process

**_Examples for Manual Testing:_**

- Ad Hoc Testing: Testers perform unplanned testing to identify defects or issues in specific areas of the application or software in a quickly manner.
- User Acceptance Testing (UAT): client representatives manually test the software to validate whether it meets their requirements and expectations which are all conducted in three levels (Alpha,Beta,Gamma)
- Security Testing: Testers manually finds the security flaws and identify vulnerabilities  in the software, such as data leakage risks or weak authentication mechanisms.

**_Functional Testing:_**
Functional testing is a type of software testing technique that verifying the software application's functions work as intended and meet the specified requirements. it validate the functionalities of the software and behaves on user perspective. functional testing comes under the black box testing method. it performed to find the functioning of software as the specified requirement.
 

- Unit testing, integration testing, system testing, user acceptance testing, regression testing are comes under functional testing.
- Test cases are design are based on functional requirements, often specified in user stories, or functional specifications.
-  It works on identifying defects related to incorrect functionality, such as incorrect outputs, improper calculations.
- software testing is highly focuses on validation like checking whether the software meets user needs and requirements.
- usually this type of testing  conducted throughout the development cycle, including unit testing, integration testing, system testing, and user acceptance testing.
- Examples:
- **_Login Functionality:_** Testing login functionality of the application using valid and invalid credentials.
- **_Form Submission:_** Verifying the software or web application that  collects forms  and store user data accurately and securely.

**_Non Functional Testing:_**
Non-functional testing is a type of software testing evaluates the attributes of a software application that are not directly related to its specific functions. Unless functional testing it assess the performance of task under various conditions and how well it handles different condition and quality attributes.

- load testing, stress testing, Performance testing, security testing, usability testing  are comes under non functional testing
- Non-functional testing aims to evaluate the software's attributes  like , security, usability  performance, and more.
- Test scenarios  are based on security standards, performance targets, and usability guideline.
- It mainly identifies defects related to , security vulnerabilities,  performance bottlenecks, security vulnerabilities, usability issues.
- It works on verification like checking whether the software meets quality   and  technical  attributes. it  executed  after functional testing
-  **_Examples:_**
- **_Performance Testing: _**Assessing the response time of a web application under different user loads.
- **_Compatibility Testing:_** Verifying a mobile app works seamlessly works in various devices, such as smartphones and tablets, with different screen sizes and resolutions.

Utilizzare i Partial in React per Componenti Configurabili
Published: 2023-09-03 22:09:39

L'utilizzo dei partial in React può migliorare notevolmente la modularità e la flessibilità dei componenti, consentendo di creare componenti configurabili con facilità. In questo articolo, esploreremo come sfruttare i partial in React attraverso un esempio concreto.

## Concetto di Partial in React

In React, i partial possono essere implementati come funzioni che restituiscono componenti con alcune prop preimpostate. Questo approccio consente di creare componenti altamente personalizzabili e riutilizzabili senza dover ripetere costantemente la stessa configurazione.

## Esempio di Uso dei Partial in React

Immaginiamo di dover creare una serie di bottoni personalizzati in un'applicazione React, con colori diversi, dimensioni e azioni al clic. Utilizzeremo i partial per semplificare la creazione di questi bottoni.

```jsx
import React from 'react';

// Definiamo un componente di base per i bottoni
function Button({ label, color, size, onClick }) {
  const buttonStyle = {
    backgroundColor: color || 'blue',
    fontSize: size || '16px',
    padding: '10px 20px',
    borderRadius: '5px',
    color: 'white',
    cursor: 'pointer',
  };

  return (
    <button style={buttonStyle} onClick={onClick}>
      {label}
    </button>
  );
}

// Creiamo dei partial per configurare rapidamente i bottoni
function createPrimaryButton(label, onClick) {
  return <Button label={label} color="blue" onClick={onClick} />;
}

function createSecondaryButton(label, onClick) {
  return <Button label={label} color="green" onClick={onClick} />;
}

function createLargeButton(label, onClick) {
  return <Button label={label} size="24px" onClick={onClick} />;
}

function App() {
  const handlePrimaryClick = () => {
    alert('Hai cliccato su un pulsante primario!');
  };

  const handleSecondaryClick = () => {
    alert('Hai cliccato su un pulsante secondario!');
  };

  return (
    <div>
      {createPrimaryButton('Pulsante Primario', handlePrimaryClick)}
      {createSecondaryButton('Pulsante Secondario', handleSecondaryClick)}
      {createLargeButton('Pulsante Grande', () => {})}
    </div>
  );
}

export default App;
```

In questo esempio, abbiamo creato un componente React di base chiamato `Button`, che accetta alcune prop come `label`, `color`, `size`, e `onClick`. Successivamente, abbiamo definito diverse funzioni `createPartialButton` che sono partial del componente `Button`. Questi partial consentono di configurare rapidamente i bottoni con diverse caratteristiche preimpostate come il colore, la dimensione e l'azione al clic.

Nel componente `App`, utilizziamo i partial `createPrimaryButton`, `createSecondaryButton`, e `createLargeButton` per generare i bottoni personalizzati con configurazioni specifiche.

L'utilizzo dei partial in React semplifica notevolmente la creazione e la configurazione di componenti personalizzati, contribuendo a rendere il codice più modulare ed espandibile.
Sfruttare i Partial in JavaScript per un Codice più Modulare ed Espandibile
Published: 2023-09-03 22:08:50

I Partial: Una Strategia per la Modularità del Codice

L'utilizzo dei partial rappresenta una strategia efficace per rendere il codice JavaScript più modulare ed espandibile. In questo articolo, esamineremo il concetto di partial e illustreremo come sfruttarlo in JavaScript per migliorare la struttura e la gestione del codice.

## Comprendere il Concetto di Partial

Un partial, o "parziale" in italiano, è una funzione che prende una funzione esistente e ne restituisce una nuova versione con alcuni argomenti preimpostati. In pratica, i partial consentono di "preconfigurare" una funzione con alcuni valori fissi in modo da semplificarne l'utilizzo in diverse parti del codice.

## Vantaggi dell'Uso dei Partial

L'utilizzo dei partial offre diversi vantaggi nel processo di sviluppo del software:

1. **Riutilizzo del Codice**: I partial permettono di riutilizzare una funzione di base in diversi contesti, evitando duplicazioni di codice.

2. **Leggibilità del Codice**: Rendono il codice più leggibile poiché evidenziano chiaramente quali argomenti sono fissi e quali sono variabili in una chiamata di funzione.

3. **Modularità**: Forniscono una maggiore modularità al codice, poiché le funzioni parziali possono essere facilmente combinate per creare comportamenti complessi.

## Esempio di Uso dei Partial

Supponiamo di avere una funzione `calculateTotal` che accetta tre argomenti: `prezzo`, `quantità`, e `sconto`. Possiamo creare una funzione parziale per calcolare il totale con uno sconto fisso e poi utilizzarla in diverse parti del nostro codice:

```javascript
// Definiamo la funzione di base
function calculateTotal(prezzo, quantità, sconto) {
  return prezzo * quantità * (1 - sconto);
}

// Creiamo una funzione parziale con sconto del 10%
const apply10PercentDiscount = (prezzo, quantità) => calculateTotal(prezzo, quantità, 0.1);

// Utilizziamo la funzione parziale
const total1 = apply10PercentDiscount(50, 2); // Calcola il totale con sconto del 10%
const total2 = apply10PercentDiscount(30, 5); // Calcola il totale con sconto del 10%
```

In questo esempio, abbiamo creato la funzione `apply10PercentDiscount` che è una funzione parziale di `calculateTotal`. Ha fissato l'argomento `sconto` a 0.1 (cioè il 10%). Ora possiamo utilizzare `apply10PercentDiscount` per calcolare il totale con uno sconto del 10% in diverse parti del nostro codice, evitando di specificare sempre lo stesso valore di sconto.

## Conclusioni

L'utilizzo dei partial è una strategia efficace per migliorare la modularità e l'espandibilità del codice JavaScript. Consentono il riutilizzo del codice, aumentano la leggibilità e promuovono la modularità, rendendo il tuo codice più manutenibile. Incorporando correttamente i partial nella tua pratica di programmazione, potrai affrontare con successo le sfide di progettazione e manutenzione del software.

I don't know how to start this but there are times we are so disappointed of who we are and what we do!

For example after about 3-4 years of developing different projects and working with different clients individually (freelance) despite my age (22), I felt like going to a great company! but when trying to apply, they have some metrics like years of experience in companies you worked full-time and also the age!

I have no pride, always trying to improve my skills and knowledge but always have the question for those who have no connections in big companies how we can join the team and develop our skills?!

Published: 2023-09-03 21:14:30

In the rapidly evolving field of machine learning, generative models have emerged as powerful tools for understanding data distribution and generating new samples.

Among them, Bayesian generative models stand out for their unique approach to incorporating uncertainty and variability in modelling.

In this article guide, we will delve into the world of Bayesian generative models, exploring how they leverage probabilistic techniques to unlock new possibilities in various applications.

Foundations of Bayesian Generative Models
Understanding Generative Models in Machine Learning
Generative models are a class of algorithms that learn to generate data that resembles a given dataset. They aim to capture the underlying distribution of the data and provide a probabilistic framework for generating new samples. In Bayesian generative models, we take this concept further by incorporating Bayesian statistics.

Bayesian Statistics and Probabilistic Modeling
Bayesian statistics is a mathematical framework that deals with uncertainty by representing probabilities as degrees of belief. In Bayesian generative models, we utilize prior knowledge and data likelihood to compute the posterior probability, which serves as our updated belief after observing new data.

Key Concepts: Prior, Likelihood, and Posterior
The three fundamental components of Bayesian generative models are the prior, the likelihood, and the posterior. The prior represents our initial belief about the parameters of the model. The likelihood quantifies how well the data is explained by the model. Through Bayes’ theorem, we combine the prior and the likelihood to compute the posterior, which represents our updated belief after incorporating the new data.

Published: 2023-09-03 21:08:22

Video Generation has emerged as a groundbreaking application of Deep Learning, enabling machines to create compelling videos that captivate audiences across industries.

In this comprehensive article, we’ll explore various techniques used to create stunning videos using deep learning models.

From frame-by-frame approaches to sequence-based methods, we’ll uncover the secrets behind generating realistic and imaginative video content.

Fundamentals of Deep Learning for Video Generation
To begin our exploration, let’s lay the groundwork by understanding the core principles of deep learning models used in Video Generation.

Understanding Generative Models in Deep Learning
At the heart of Video Generation lies Generative Models, which can create new data instances that resemble a given dataset. Two prominent generative models are:

Generative Adversarial Networks (GANs)
GANs consist of two neural networks, the generator, and the discriminator, engaged in a captivating game. The generator attempts to create realistic videos, while the discriminator aims to differentiate between real and generated videos. This adversarial process leads to the refinement of the generator’s ability to produce high-quality content.

Variational Autoencoders (VAEs)
In contrast to GANs, VAEs employ an encoder-decoder architecture that learns a low-dimensional representation (latent space) of the input data. This latent space enables smooth interpolation and exploration of different video variations.

Data Representation for Video Generation
To generate videos effectively, we need to represent the data in a manner that captures both spatial and temporal dependencies.

Frame-level Representation
Frame-level representation treats each video frame as an individual entity. This approach is suitable for short videos or when temporal coherence is not crucial.

Sequence-level Representation
Sequence-level representation considers the temporal aspect of videos, treating the entire video as a sequence of frames. This approach captures the dynamic nature of videos and enables long-range temporal dependencies.
