Agile Test Estimation Tool (QA Tools)

Agile Test Estimator

User Story Points to Hours Factor

Total User Story Test Effort: 0 hours

Other Tasks

QA Environment Preparation

Negative Testing Effort

Exploratory Testing Effort

Regression Testing Effort

Other Testing (Performance, Security etc.) Effort

Defects Logging and Re-testing Effort

Total Test Effort: 0 hours

How to Use Agile Test Estimator

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 Agile Test Estimation tool tutorial.

To use the Agile Test Estimator:

1. Review the User Story Points to Hours Factor. If needed, adjust it according to your project.
2. Enter the following information for each user story:
   • User Story ID (optional): An identifier for each user story. If entered, it will appear in JSON and CSV exports.
   • Testing Points: 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).
   • Testing Effort: The test effort is the product of Testing Points and User Story Points to Hours Factor. It will be displayed automatically.
3. Enter the estimated effort in hours required for the following tasks, as needed:
   • QA Environment Preparation
   • Negative Testing
   • Exploratory Testing
   • Regression Testing
   • Other Testing (such as performance testing, security testing, etc., as in your Test Strategy)
   • Defects Logging and Re-testing
4. The total test effort will be displayed in the "Total Test Effort" field automatically.

Example Output:

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

Agile Test Estimator Usage Notes:

• 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.
• 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.
• The Agile Test Estimator can be used to estimate the testing effort for individual user stories or for your entire project.
• The Agile Test Estimator can export the test effort estimates to JSON format, for integration with test management tools or reporting tools.
• 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.

Asynchronous JavaScript

Great job on starting a new lesson! In the FAQ, test yourself by clicking the correct answer for each question. Then, click Next button at bottom right to continue.

Asynchronous JavaScript

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.

What is Asynchronous in JavaScript?

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.

Asynchronous JavaScript vs Synchronous

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.

Where is Asynchronous JavaScript Used?

Asynchronous JavaScript is used in various scenarios, including:

1. Fetching data from APIs
2. Performing file I/O operations
3. Handling user interactions and events

Asynchronous JavaScript Example

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();

This example uses the fetchData() function, which returns a promise that resolves after a delay of 5000 milliseconds. The displayData() function uses await to wait for the promise to resolve and then logs the result.

3. What are promises and how do they handle asynchronous operations?
   Promises in asynchronous JavaScript are used for synchronous operations.
   Promises in asynchronous JavaScript represent the eventual completion or failure of an asynchronous operation and allow you to handle the result using then() and catch() methods.
   Promises in asynchronous JavaScript are limited to handling only simple operations.

JavaScript Arrays

Great job on starting a new lesson! In the FAQ, test yourself by clicking the correct answer for each question. Then, click Next button at bottom right to continue.

JavaScript Arrays

You can use arrays in JavaScript to store multiple values in a single variable. JavaScript arrays allow you to organize and manipulate collections of data. They are useful for storing lists, sets of values, or any data element that you can access by its index number.

What are JavaScript Arrays?

JavaScript arrays are a type of object that holds multiple values in a specific order. They can contain any data type, including numbers, strings, objects, or even other arrays. Arrays in JavaScript are zero-indexed, meaning the first element is at index 0.

JavaScript Arrays Example

// JavaScript array example
// Create a JavaScript array called fruits
var fruits = ['apple', 'banana', 'cherry'];
for (var i = 0; i < fruits.length; i++) {
  document.write(fruits[i] + '<br/>');
}
document.write("Array length: " + fruits.length);
