![]() Cutting down on the number of lines of code in each test, making each one much more readable. Containing each function call in its own page object. It reminds me of the goal of the page object model which I use in all of my Selenium frameworks. Conclusionīeing able to use Helium code as well as Selenium’s own is probably what makes this such an interesting library. As well as make low-level calls to Selenium’s own API if they so wish. This allows users of Helium to take advantage of the various methods built-into the library. For example: # A Helium function:ĭriver.execute_script("alert('Hello World!') ") Which enables users of Helium to mix Selenium’s own API calls with Helium. All you need to add to the start_chrome() call is:įirefox works for this as well! Use Selenium’s own APIĪs mentioned, Helium is a wrapper around the core methods of Selenium. If you do want to turn on headless browsing in Helium though. However, if you wish to monitor your tests running or perform visual checks, using a headless option might not be the best solution for your needs. They allow you to run your tests, perform actions like web scraping, and monitor network performance in no time at all. Headless browsers, as a result, are much faster than their traditional counterparts. Not having to deal with a clunky interface that can slow down your test scripts, or consume those valuable resources that you need. Headless browsers have many advantages over the regular UI based applications that we interact with every day. Enabling the ability to test in multiple browsers very easily. This gives you the option to change browers without having to use configuration files or modify your settings. You can also easily change the browser which is used by entering: start_firefox Menu_text = Text(to_right_of='Login').valueĭef test_docket_should_have_register_text(): Please note that if you want to run the example, you will need pytest. It accesses the application and ensures that the top menu text contains the ‘Register’ text option. ![]() Here is a sample script which I wrote to test the menu structure for Docket. Allowing users to write code that is much more high-level, shorter and easier to read. At the same time, you don’t lose anything by using Helium, because you can freely mix it with Selenium.Įssentially, Helium is a wrapper around Selenium’s inbuilt functions and methods. Your automation scripts become 50% shorter, easier to read and more stable. It wraps around Selenium-python to provide an API that is much easier to use. Helium is a Python library for automating browsers such as Chrome and Firefox. But that stopped being offered at the end of last year and the Python code was open-sourced. There was a paid version that included Java code. It’s important to note here that the Helium is only for Python. Helium describes itself as ‘Lighter web automation based on Selenium’. This is what led me to discovering Helium. It’s fairly easy to lose hours at a time reading the various posts on the site and discovering new and exciting projects. It collects news articles from peoples own submissions and displays them to visitors. Which I’m sure many people reading this blog are familiar with.īut in case you’re not, Hacker News is what is known as a news aggregator. One of my favourite places to go to find out about new open-source projects is Hacker News. Finally, releasing their project for free on Github for us all to consume, modify and learn from. Often working with only the recognition of the community to appreciate their efforts. I find it allows people to be expressive and creative with their programming abilities. Time spent trying to solve issues with your framework is a barrier to a positive result. Your goal needs to be making a quick ROI on the investment you are making. When building a new automation framework. Leading to tests failing and lost time in trying to debug the cause of your newest error message. Selenium is also prone to flaky tests if they are not coded well. Or know your CSS selector from your XPATH. A learning curve that can be quite steep if you don’t know your way around the DOM. One of the problems that Selenium has is there is a learning curve to using it well. And have been proven to be the right solution for most peoples needs. These tools have been tried and tested by many people, in many situations. Whether it’s an eCommerce site, CRM tool, or SaaS product. These established libraries are perfect for building frameworks that test the whole of your web application. You might instinctively be drawn to Selenium, Cypress or maybe alternative solutions like Puppeteer. ![]() When assessing the tools to take care of browser automation to test your new web app.
