npm install cypress

Cypress automatically generates a directory with several subfolders on installation, namely fixtures, integration, plugins, support, screenshots, and videos.

Initialize Cypress with the following command:

npx cypress open

This opens up the interactive Cypress app.

Step Two: Writing Cypress Tests

Below we have a basic Cypress test which covers navigation through different routes and authentication in a ReactJS app:

describe('Gallery App', () => {
    cy.visit('http://localhost.com');
    
    it('should display the home page', () => {
        cy.contains('Welcome to the Gallery App').should('be.visible');
    });

    it('should navigate to Sign In page', () => {
        cy.contains('Sign In').click();
        cy.url().should('include', '/signin');
    });

    it('should navigate to Sign Up page', () => {
        cy.contains('Sign Up').click();
        cy.url().should('include', '/signup');
    });

    it('should navigate to Gallery page', () => {
        cy.contains('Gallery').click();
        cy.url().should('include', '/gallery');
    });
});

Now, to execute Cypress tests, simply run:

./node_modules/.bin/cypress open

Running Cypress Tests on Sauce Labs

To run tests on Sauce Labs, adjust the Cypress environment variable CYPRESS_BASE_URL and CYPRESS_VIDEO_COMPRESSION. Tip: Add your Sauce Labs username and accessKey in the config file.

Use the command as before to run the tests. The results should display all tests as passing.

Some Challenges to Keep in Mind

Despite its many advantages, there are some potential pitfalls with Cypress you should be aware of:

  • Flaky Tests: Due to Cypress running tests against real browsers, unstable network connections or server loads can sometimes cause failures.

  • Limited Browser Compatibility: While Chrome, Firefox, and Edge are supported, Safari and older browsers are not.

  • Speed: Extensive Cypress tests can become slow to execute due to the actual spinning up of real browsers.

  • Debugging: While powerful, Cypress debugging tools can still be complex and difficult, particularly for more extensive applications.

Best Practices for Cypress Testing

Let’s wrap up with some key practices to mind while you’re using Cypress:

  1. Independence: Keep each test focused on one functionality and independent of others.

  2. Use Page Objects: This will help to keep your tests DRY and maintainable.

  3. Brevity: Keep your tests short and focused. This aids in easy debugging and maintenance.

  4. Annotation: Keep commenting on your tests to convey their intent.

  5. Review Practices: As your understanding grows, your best practices will evolve, so revisit them regularly.

Conclusion

Cypress is a powerful and reliable tool for end-to-end testing in your ReactJS applications. It helps to improve the speed, effectiveness, and reliability of your tests.

Enhance Your Coding with JavaScript and TypeScript Shorthand Techniques

Optimizing your workflow is one of the key steps to becoming a proficient developer, and a great way to do that is by learning and implementing shorthand alternatives in your code. Two languages that offer many opportunities for shorthand coding are JavaScript and TypeScript. This guide will walk you through several shorthand alternatives that can make your code cleaner, more scalable, and easier to read.

Table of Contents

Ternary Operator

A ternary operator is a shortcut for an if...else statement, and is made up of three parts: a condition, a result for true, and a result for false. Here’s an example of how it can simplify your code:

// Longhand
const mark = 80;
if (mark >= 65) {
  return 'Pass';
} else {
  return 'Fail';
}

// Shorthand
const mark = 80;
return mark >= 65 ? 'Pass' : 'Fail';

Short-circuit Evaluation

This is a less-known yet handy feature that uses the OR (||) operator. It allows you to run an operation not when the first operand is true, but when the first operand is false.

// Longhand
let str = '';
let finalStr = str || 'default string';

// Shorthand
let str = '';
let finalStr;
if (str !== null && str !== undefined && str != '') {
  finalStr = str;
} else {
  finalStr = 'default string';
}

Nullish Coalescing Operator

The nullish coalescing operator checks whether a provided variable is null or undefined and returns a provided default value if it is null or undefined. It’s a shorter and more intuitive way to default-assign your variables.

// Longhand
let num = null;
if (num !== null && num !== undefined) {
  actualNum = num;
} else {
  actualNum = 0;
}

// Shorthand
let num = null;
let actualNum = num ?? 0;

Template Literals

Template literals, introduced with the ES6 syntax, allow for easier string manipulation. They are a new way to create strings and allow embedded expressions, multiline strings, and string formatting.

// Longhand
const name = 'Iby';
const hobby = 'to read';
const fullStr = name + ' loves ' + hobby;

// Shorthand
const name = 'Iby';
const hobby = 'to read';
const fullStr = `${name} loves ${hobby}`;

Object Property Assignment Shorthand

In JavaScript and TypeScript, you can assign a property to an object in shorthand. This simply involves mentioning the variable in the object literal.

// Longhand
const obj = {
  x: 1,
  y: 2,
  z: 3,
}

// Shorthand
const x = 8;
const y = 10;
const obj = {x, y};

Optional Chaining

The optional chaining operator permits reading the value of a property located deep within a chain of connected objects without having to check that each reference in the chain is valid.

// Longhand
const obj = {
  x: {
    y: 1,
    z: 2
  },
  others: ['test', 'tested']
};
if (obj.hasOwnProperty('others') && obj.others.length >= 2) {
  console.log('2nd value in others: ', obj.others[1]);
}

// Shorthand
const obj = {
  x: {
    y: 1,
    z: 2
  },
  others: ['test', 'tested']
};
console.log('2nd value in others: ', obj.others?.[1]);

Object Destructuring

Object destructuring allows you to create a new variable by extracting some properties from an object and can greatly simplify your code.

// Longhand
const obj = {
  x: {
    y: 1,
    z: 2
  },
  other: 'test string',
};
console.log('Value of z in x: ', obj.x.z);
console.log('Value of other: ', obj.other);

// Shorthand
const obj = {
  x: {
    y: 1,
    z: 2
  },
  other: 'test string',
};
const { x, other } = obj;
const { z } = x;
console.log('Value of z in x: ', z);
console.log('Value of other: ', other);

Spread Operator

The spread operator allows an iterable to be expanded in places where zero or more arguments or elements are expected. In simpler terms, it’s a quick, easy way to copy all properties from one object to another or to combine two different arrays.

// Longhand
const arr = [1, 2, 3];
const biggerArr = [4, 5, 6].concat(arr);

const smallObj = {
  x: 1
};
const otherObj = Object.assign(smallObj, { y: 2 });

// Shorthand
const arr = [1, 2, 3];
const biggerArr = [...arr, 4, 5, 6];

const smallObj = {
  x: 1
};
const otherObj = { ...smallObj, y: 2 };

JavaScript is one of the primary programming languages for web browsers, enabling you to create interactive and dynamic web applications. In recent years, TypeScript, a statically-typed superset of JavaScript, has gained popularity for its ability to enhance JavaScript development. Make sure to delve deep into JavaScript fundamentals, libraries, and frameworks like React and Angular.

Git: Version Control for Efficient Collaboration

Git has become the de facto standard for version control in the software development industry. Every full-stack developer should be proficient in essential Git operations such as committing code, merging branches, and managing repositories on platforms like GitHub, GitLab, or BitBucket. Embrace Git workflows to collaborate effectively with other developers and ensure the integrity and manageability of your codebase.

Mobile App Development: Extending Your Reach

Full-stack development encompasses mobile app development as well. To cover all bases, familiarize yourself with mobile application development frameworks and languages. Swift is the language for developing applications for iOS devices, while Kotlin is the language of choice for Android development. Alternatively, you can use a cross-platform framework like React Native to build apps for both iOS and Android simultaneously.

Building RESTful APIs: Connecting Clients and Servers

Developing RESTful APIs is a crucial skill for full-stack developers. Master the art of designing and building API gateways that allow clients to access server resources. Understand how to consume RESTful APIs from client-side applications and secure them through authentication and encryption. Create scalable, reliable APIs that facilitate seamless communication between clients and servers using JSON as the data exchange format.

SQL and Relational Databases: Managing Data Effectively

While NoSQL databases are gaining popularity, relational databases remain the backbone of many enterprise-scale applications. Full-stack developers should have a solid understanding of structured query language (SQL) and the principles of relational database management. Learn to work with large-scale databases that store vast amounts of data, and grasp optimization techniques to ensure efficient data retrieval and manipulation.

Middle Tier Technologies: Bridging the Gap

The middle tier acts as a bridge between the client and backend database tiers. As a full-stack developer, you need to familiarize yourself with middle-tier programming languages and associated technologies. Java is a popular choice for integrating with application servers and cloud APIs. Python shines when it comes to machine learning or AI projects, while JavaScript provides a versatile option that spans different layers of the stack.

Cloud-Native Deployment with YAML: Infrastructure as Code

Cloud-native development is revolutionizing the way applications are built and deployed. Familiarize yourself with YAML, the standard app configuration language for cloud-native technologies. Use YAML to configure infrastructure as code with tools like Terraform, implement continuous integration and deployment pipelines with platforms like GitHub Actions, deploy applications using containers with Docker and Kubernetes, and manage network gateways on AWS.

Getting Close to the Metal: Low-Level Programming

While many full-stack developers focus on high-level languages, some projects may require low-level programming skills. Rust, Go, and C are languages that allow you to code components for operating systems, embedded systems, hypervisors, cryptography, and security. These languages eliminate the need for an abstraction layer, providing direct control over hardware resources.

Committing to the 12-Factor App: Cloud-Native Best Practices

To stay ahead in the world of cloud-native development, commit to the 12-Factor App principles. These practices provide guidelines for building scalable, resilient, and maintainable cloud-native applications. Whether deploying microservices, serverless functions, or lambda procedures, ensure your applications adhere to the 12 factors and take full advantage of cloud-native environments.
