<h4>How to Use Mock Data Generator</h4>
<p>The Mock Data Generator is a tool that can be used to generate realistic and meaningful mock data for testing software. The tool can be used to generate a variety of data types, including:</p>
<ul>
<li>Names</li>
<li>UserNames</li>
<li>Passwords</li>
<li>Emails</li>
<li>Handles</li>
<li>Phone Numbers</li>
<li>Street Addresses</li>
<li>Postal/Zip Codes</li>
<li>Countries</li>
<li>And much more!</li>
</ul>
<p>The Mock Data Generator can be used to generate normal, lower boundary, upper boundary and erroneous mock data for a variety of purposes, such as:</p>
<ul>
<li>Testing the functionality of a software application</li>
<li>Generating data for training machine learning models</li>
<li>Creating seed data for a database</li>
<li>And many more!</li>
</ul>
<p>To use the Mock Data Generator, simply visit <a href="https://inderpsingh.blogspot.com/2023/11/data-generator.html"> Mock Data Generator</a> web page.</p>
<p>On the website, you will see a dropdown where you can select the types of data you want to generate. In the dropdown, choose one or more option(s). Then click Preview Data. If you want to export mock data of the selected option(s), enter the number of records that you want to generate. Then click Export as CSV.

<h3>How to Use Agile Test Estimator</h3>
<p>The Agile Test Estimator is a tool that helps software development teams estimate the testing effort required for their projects. It allows users to input data for each user story, such as the number of testing points, and then calculates the total test effort based on a variety of factors, including the QA environment preparation effort, negative testing effort, exploratory testing effort, regression testing effort, other testing (performance, security, etc.) effort, and defects logging and re-testing effort. If you want to learn how to use it, please see the <a href="https://youtu.be/oWlrqbsHYds" target="_blank">Agile Test Estimation tool tutorial</a>.</p>
<h4>To use the Agile Test Estimator:</h4>
<ol>
<li>Review the User Story Points to Hours Factor. If needed, adjust it according to your project.</li>
<li>Enter the following information for each user story:
<ul>
<li><strong>User Story ID (optional):</strong> An identifier for each user story. If entered, it will appear in JSON and CSV exports.</li>
<li><strong>Testing Points:</strong> The number of Story Points for testing of that user story. Note that the full Story Points consider the size of all tasks (development, testing, deployment, and so on).</li>
<li><strong>Testing Effort:</strong> The test effort is the product of Testing Points and User Story Points to Hours Factor. It will be displayed automatically.</li>
</ul>
</li>
<li>Enter the estimated effort in hours required for the following tasks, as needed:
<ul>
<li><strong>QA Environment Preparation</strong></li>
<li><strong>Negative Testing</strong></li>
<li><strong>Exploratory Testing</strong></li>
<li><strong>Regression Testing</strong></li>
<li><strong>Other Testing (such as performance testing, security testing, etc., as in your Test Strategy)</strong></li>
<li><strong>Defects Logging and Re-testing</strong></li>
</ul>
</li>
<li>The total test effort will be displayed in the "Total Test Effort" field automatically.</li>
</ol>
<h4>Example Output:</h4>
<pre>
User Story ID,Testing Points,Test Effort (hours)
Login,1,2
Add to Cart,3,6
Other Tasks,Test Effort (hours)
QA Environment Preparation,1
Negative Testing Effort,2
Exploratory Testing Effort,2
Regression Testing Effort,2
Other Testing (Performance, Security etc.) Effort,2
Defects Logging and Re-testing Effort,2
Total Test Effort,19
</pre>
<h4>Agile Test Estimator Usage Notes:</h4>
<ul>
<li>The Agile Test Estimator is a tool, not a replacement for human judgment. Use this tool in conjunction with your own knowledge and experience to estimate the testing effort for your project, release, or sprint.</li>
<li>The default values for the other tasks, such as QA environment preparation effort and negative testing effort, are reasonable for most projects. However, you can adjust these values as needed.</li>
<li>The Agile Test Estimator can be used to estimate the testing effort for individual user stories or for your entire project.</li>
<li>The Agile Test Estimator can export the test effort estimates to JSON format, for integration with test management tools or reporting tools.</li>
<li>The Agile Test Estimator can export the test effort estimates as a CSV report. You can open this CSV report in Excel and share it with your team members or stakeholders.</li>
</ul>

In the FAQ, test yourself by clicking the correct answer for each question. Then, click <b><span style="background-color: red; color: white;">Next</span></b> button at bottom right to continue.</i></p><h4>Asynchronous JavaScript</h4>
<p>Asynchronous JavaScript allows you to perform tasks without freezing the execution of other code. It uses callbacks, promises, and async/await to handle asynchronous operations.</p>
<h4>What is Asynchronous in JavaScript?</h4>
<p>In JavaScript, asynchronous refers to the ability to execute tasks without freezing the execution of other code. Asynchronous operations allow you to handle time-consuming tasks such as making network requests or accessing databases without freezing the entire program.</p>
<h4>Asynchronous JavaScript vs Synchronous</h4>
<p>Asynchronous JavaScript allows code to continue executing while waiting for certain operations to complete, improving responsiveness. In contrast, synchronous JavaScript blocks the execution of other code until an operation is complete, potentially causing delays.</p>
<h4>Where is Asynchronous JavaScript Used?</h4>
<p>Asynchronous JavaScript is used in various scenarios, including:</p>
<ol>
<li>Fetching data from APIs</li>
<li>Performing file I/O operations</li>
<li>Handling user interactions and events</li>
</ol>
<h4>Asynchronous JavaScript Example</h4>
<pre><code>function fetchData() {
return new Promise((resolve, reject) => {
setTimeout(() => {
const data = 'Example data';
resolve(data);
}, 5000);
});
}
async function displayData() {
const result = await fetchData();
console.log(result);
}
// Open Developer Tools Console. The Example data should be displayed after 5 seconds.
displayData();</code></pre>
<p>This example uses the <code>fetchData()</code> function, which returns a promise that resolves after a delay of 5000 milliseconds. The <code>displayData()</code> function uses <code>await</code> to wait for the promise to resolve and then logs the result.</p>

</li>
<li>
<b>What are promises and how do they handle asynchronous operations?</b><br />
<input name="q3" onclick="this.parentNode.style.color = 'red';" type="radio" value="incorrect" />Promises in asynchronous JavaScript are used for synchronous operations.<br />
<input name="q3" onclick="this.parentNode.style.color = 'green';" type="radio" value="correct" />Promises in asynchronous JavaScript represent the eventual completion or failure of an asynchronous operation and allow you to handle the result using <code>then()</code> and <code>catch()</code> methods.<br />
<input name="q3" onclick="this.parentNode.style.color = 'red';" type="radio" value="incorrect" />Promises in asynchronous JavaScript are limited to handling only simple operations.<br />
