What techniques can you use to test text alternatives in web testing?

When testing web pages for text alternatives, I start by looking at each picture, video, and sound piece manually. I use tools like the browser's developer tools to see the text that should describe these non-text items. I check if this text really says what the item is about, is short yet clear, and fits the page's content. I also look for any mistakes in spelling or grammar. This simple way helps me make sure the web page can be understood by everyone, including people who use screen readers.

For testing text alternatives, I also use user testing, especially with people who have disabilities or use assistive tech. Heres how I do it: I find users to help with the test, including those who rely on screen readers. I set up tasks or situations for them to try on the web page. I watch how they use the text alternatives while doing these tasks. I ask for their thoughts on whether the text helps, is clear, and fits what they need. This way, I get to see if the text alternatives really work for users and find any issues I didn’t notice before.

To check if text alternatives work well, I test on many browsers and devices. Here's what I do: I open the web page on different gadgets like computers, tablets, and phones. I use browsers like Chrome, Firefox, Safari, and Edge to see how things look there. I change the screen size and the way it's turned to check everything still looks okay. Doing this helps me make sure the text that describes pictures or videos is good everywhere, no matter what device or browser someone is using. It's a simple way to catch problems early. :)

Cross-browser compatibility is crucial for ensuring a consistent user experience across various platforms. iOS devices, particularly when using Safari, can present unique challenges due to its distinct rendering methods & handling of web standards. Safari often implements certain features or interprets code differently compared to other browsers like Chrome, Firefox, or Edge. This can lead to inconsistencies in styling, or functionality, requiring developers to employ specific workarounds to address these differences. To ensure a seamless experience, web developers often need to conduct thorough testing across multiple browsers & devices, including iOS devices, to identify & address any compatibility issues early in the development process.
