Field java reflection to webelement3/25/2023 ![]() ![]() The final step is to have Selenium initialize my page beans, i.e. This is mostly a standard Spring context test case, but it also adds my own test execution = SeleniumTestExecutionListener.class,ÄependencyInjectionTestExecutionListener.class }) I start by creating a base class for my Selenium test cases. The framework we have today has a lot of extra features not mentioned above, but I will try to extract the basic classes needed for working with page objects and Spring. I will write a follow-up to this post explaining the other cool stuff we have done with the new framework. We now have a good set of readable tests and we have page objects covering most of the functionality on the site, meaning itâs very cheap to add new tests. The team approved of my design and just last week we refactored the last of the old tests to use the new framework. My page objects became singleton beans which could be injected into test classes and into other page objects. By doing this I could remove the boilerplate code of calling the PageFactory in each page object. By default, the name of the field is matched against the id of the HTML element, but the field can also be annotated with an expression for matching against class names, css, xpath, etc.Īpplying the pattern to our tests really cleaned them up but I wanted to take things one step further by also applying dependency injection. Each field is proxied allowing for a lookup of the corresponding HTML element when the field is accessed. This class uses reflection to find all fields of type WebElement in a page object. The Selenium framework supports this pattern by providing a utility for setting up page objects, the PageFactory class. The pattern can also be applied to parts of pages, where a page object can represent for example a lightbox. Each page on the site is represented by a class containing the logic for locating the elements on that page. The Page object pattern is a design pattern where the logic of navigating and interacting with the site is separated from the actual test code. Thatâs when I stumbled upon the Page object pattern. But I was also determined to come up with a design where we could write readable and maintainable tests, composed of reusable parts. getFields () - Returns an array containing Field objects reflecting all the accessible public. getField (String name) - Returns a Field object that reflects the specified public member field of the class or interface represented by this Class object. There are 4 methods for getting fields of the class. Since the whole team was committed I decided to support the effort. How to get Field object using reflection. When I came back from a couple of months of paternity leave, my team had decided to make a new attempt at creating Selenium tests for the product. And that can only be accomplished by skilled programmers. The value is when you have a suite of well written, easy to understand test cases that can be maintained at a low cost. I donât believe there is any value in creating large amounts of tests in little time. That a person with little or no programming skill can record their actions when they interact with the site and turn this into a test case. I have often been told that itâs a good thing that everyone can create tests. Basically they resembled the output from the Selenium IDE Firefox plugin. They were written in the classic script form were every other line is either a âdriver.findElement(â¦)â or ândKeys(â¦)â, obscuring the purpose of the test. The reason they failed? The tests werenât readable so we couldnât easily understand or extend them and they became a nightmare to maintain. Some months later we threw them all away. They worked hard for months, struggling with the business logic and page design and came up with a huge set of tests. I believe the worst one was when a team of off-site contractors was hired to create a proof of concept. Several attempts have been made over the years, each failing miserably. The project Iâm assigned to is a quite large and complex customer web portal and has always been in need of automated GUI checks. The steps are âgluedâ together using Cucuember.I have to admit, a couple of years ago I wasnât a huge fan of Selenium. The second statement for Pagefactory after FindBy is assigning an of type WebElement class that works exactly similar to the assignment of an element name of type WebElement class as a return type of the method driver.findElement () that is used in usual POM (searchNSETxt in this example).The current structure of our project is something like: mobile In my team weâre doing cross platform UI testing using Appium and the Appium Java-Client. ![]()
