Iframe test
Instead of testing the existence of scroll bars, the tester might simply use text locators to validate that the content exists in the DOM. The engineer might choose not to exercise the scroll bars, and leave that task to the user later.
But, validation and assertion technologies limit traditional functional test approaches.įor example, a tester may get a version of the app with scroll bars in a nested iFrame. Also, there are dependencies on the version of the application itself. Selenium can accomplish iFrame resizing and scrolling, but the efforts to do these tasks depend very much on the test engineer. Selenium Testing iFrame Application Versions If a scroll bar does not exist, can the user see data that does not show up on the page? How does a tester use an automated tool to expose this behavior? Hidden content can create problems in testing, because the test may not uncover the error.Īnd, thus, the issue of scroll bars. When pages resize and frame content gets hidden, the user may not know the content exists, or its values. Hidden ContentĪnother complication involves the hidden parts of frames.

This is a lot of redundant code needed to navigate around to each iFrame. Here is a highlight of the code used to change context: Finally, you select one of the four embedded iFrames. In the code that follows, Raja shows the redudnant code you need to add to navigate the different nested iFrames. And, you have to extract your context to go back to the page outside the iFrame. Each time you navigate in an iFrame, you must change the context of the iFrame you’re inspecting.
The first is the challenge of navigating iFrames – especially if you have nested them. There are several complications he exposes. Raja walks into the legacy approach to testing iFrames – using Selenium to apply a test behavior and then measure the response of the page. And, in some cases, there may not be scroll bars – meaning a user must manually resize the page to see the data. Depending on the design approach, this hidden data may not become visible unless the user scrolls the data manually. As the page is resized, the top-level iFrame resizes, and the content in the nested iFrame gets hidden. Raja imagines a test of a table in a nested iFrame. How do you test the iFrame? Testing iFrames with Selenium Or not – some iFrame implementations are fixed with no scroll bars. The big problems occur with testing iframes sized smaller than their contents – which results in scroll bars on the iFrame to access all the content. In this example, Raja points out design considerations that your developers may not have considered when designing your app. In other designs, the mobile device behavior might not be acceptable. For some designs, the behavior works fine on a mobile device but gets lost on a desktop or laptop scree. These behaviors get complicated by how you define your iframe and ensure its boundaries. You will want to ensure that buttons behave as expected, scrolling regions scroll, and expected information gets presented to the user. You will want to test the data and functionality in your iFrames. They have their own behaviors that need to be tested. These iFrames have their own contents, buttons, and scrolling regions. Buttons and functionality inside the iFrame will need to be tested. When you test iFrames designed for users interaction, the iFrame can behave as if is part of your app. The challenge comes around building interactive iFrames. As I mentioned, some are one or zero pixels high. IFrames can be built to the size of the user’s screen, or any subset of your app page. How do you test an iFrame? Possible iFrame Errors They are embedded in your web app – sometimes nested. What matters, then, are the pages that include iFrames for extended functionality. They will exist in your DOM, but end users won’t know about their existence. The existence of zero pixel iFrames cannot be detected in your end-user and integration testing. In fact, some of these tracking iFrames are zero pixel iFrames, meaning they are invisible on your page. You can use the tracking pieces to know where your customers go on your web app. Yup, this code will embed a Google Map of Alice Springs, Northern Territory, Australia.
