In today’s rapidly evolving software development industry, it’s essential to have a robust and efficient testing infrastructure. Protractor is a popular end-to-end testing framework for AngularJS applications that allows developers to automate their testing process and ensure that their applications are functioning as expected. However, mastering Protractor can be a daunting task, especially for those new to the framework. This article aims to provide essential tips and tricks that will help you become an expert in Protractor and improve the efficiency of your testing process. Whether you’re a beginner or an experienced developer, this article has something for everyone. So, let’s dive in and learn how to master Protractor!
Revving Up Your Protractor Tests: Tips and Tricks for Lightning-Fast Automation
Protractor is a popular end-to-end testing framework for Angular applications. It’s a great tool for automating tests, but as your test suite grows, the time it takes to run your tests can start to become a bottleneck. In this article, we’ll cover some tips and tricks for speeding up your Protractor tests and making your automation lightning-fast.
1. Use async/await
One of the biggest advantages of Protractor is that it supports asynchronous testing out of the box. However, if you’re still using callbacks, you’re missing out on the power of async/await. Using async/await can make your code much cleaner and easier to read, and it can also speed up your tests by reducing the amount of time spent waiting for promises to resolve.
2. Use the right locators
Choosing the right locator strategy can have a big impact on the speed of your tests. CSS selectors are generally faster than XPath, but they can also be less reliable. If you’re having trouble with flaky tests, it might be worth trying a different locator strategy to see if it improves your test performance.
3. Use page objects
Page objects are a design pattern that can help to make your tests more maintainable and easier to read. They can also help to speed up your tests by reducing the amount of time spent searching for elements on the page. By encapsulating the logic for interacting with a page in a separate class, you can avoid repeating code and make your tests more modular.
4. Run tests in parallel
Protractor supports running tests in parallel, which can be a great way to speed up your test suite. By running multiple tests at the same time, you can make better use of your testing infrastructure and reduce the overall time it takes to run your tests. However, it’s important to make sure that your tests are designed to run in parallel and that they don’t interfere with each other.
5. Use headless mode
Starting a browser can be one of the slowest parts of running a Protractor test. By running your tests in headless mode, you can skip the time it takes to open and close a browser window. This can be a great way to speed up your tests, especially if you’re running them on a remote Selenium Grid.
By following these tips and tricks, you can make your Protractor tests lightning-fast and more efficient. Whether you’re running a small test suite or a large one, these techniques can help you to get the most out of your automation efforts.
Mastering Automated Testing: A Guide to Protractor Testing
Automated testing has become an essential part of any software development process. It is a technique that is used to verify whether the software is working as expected or not. Protractor is a popular end-to-end testing framework for Angular applications. This guide will help you in mastering automated testing with Protractor.
Why do we need automated testing?
Automated testing helps in reducing the time and effort required to test the application manually. It also helps in detecting bugs and issues early in the development process, which leads to faster and efficient development.
What is Protractor?
Protractor is an end-to-end testing framework for Angular applications. It is built on top of WebDriverJS and supports both Angular and non-Angular applications. Protractor provides a simple and easy-to-use API for testing Angular applications.
How to set up Protractor?
To set up Protractor, you need to have Node.js and npm installed on your system. You can install Protractor using the following command:
npm install -g protractor
Once Protractor is installed, you can start using it to write tests for your Angular applications.
Writing your first Protractor test
To write your first Protractor test, you need to create a new file and add the following code:
describe(‘Protractor Demo App’, function() {
it(‘should have a title’, function() {
browser.get(‘http://juliemr.github.io/protractor-demo/’);
expect(browser.getTitle()).toEqual(‘Super Calculator’);
});
});
This test will open the Super Calculator application and check whether the title is correct or not.
Using locators in Protractor
Locators are used to identify the elements on a web page. Protractor supports several types of locators such as by.model, by.css, by.id, by.name etc. Here’s an example of using locators in Protractor:
element(by.model(‘first’)).sendKeys(1);
element(by.model(‘second’)).sendKeys(2);
element(by.id(‘gobutton’)).click();
expect(element(by.binding(‘latest’)).getText()).toEqual(‘3’);
This test will input the values 1 and 2 in the first and second input fields of the Super Calculator application, click on the Go button and check whether the result is correct or not.
Conclusion
Protractor is a powerful and easy-to-use end-to-end testing framework for Angular applications. It provides a simple and efficient way to write tests and helps in detecting bugs and issues early in the development process. By mastering Protractor, you can become a proficient automated tester and improve the overall quality of your software.
