4. PerfectPixel

When testing the UI — the look and feel of web application — it is important to check every pixel. In addition, many customers, when ordering a layout or a site, indicate in the terms of reference that the layout should be pixel-perfect. This means that it must match to the finest details to what is drawn on the site design mockup in Photoshop (PSD mockup).

 

The PerfectPixel Extension allows you to make sure that all pixels are in place. Using it, you can superimpose a semi-transparent image on top of HTML page and do a pixel analysis.

 

The extension is distinct in a convenient and user-friendly interface, high functionality, easy connect and comfort settings that allow you to test the product faster and more efficiently.

5. Lorem Ipsum Generator

When developing a web page, it is filled with specially generated Lorem Ipsum text. This is a so called dummy text. Lorem Ipsum generators are effective for testers and web designers to use. For instance, QA experts use the extension for the Lorem Ipsum Generator browser when they need to quickly fill in fields for the form testing.

 

In addition, such dummy text saves time for web designers (they do not have to wait for ready-made content to appear) and allows the customer to focus on evaluating the product design. Moreover, the customer cannot always immediately provide the designer with already prepared advertising slogans, texts describing the product contents or a set of articles for the site under development. In this case, the Lorem Ipsum generator helps significantly.

 

With this extension, you can also adjust the text size for the dummy text. You just need to copy the finished placeholder from the online generator page and paste it on the site.

6. FakeFiller 

The Chrome Extension that helps fill the input data on a page with fake information. The form developers and testers are actively using it as it obviates the need to manually enter the values ​​into fields. All data are filled with randomly generated names, e-mails, phone numbers, etc. What the plugin can do:

• With one button, all fields are filled in at once — either 7, 25 or 110.
• Each time the extension fills in the fields with different values. So you can easily create 10 different users, product cards, etc.
• Supports the maxLength property.
• Randomly fills in the dropdowns, checkboxes, and radio buttons.
• Ignores CAPTCHA, hidden, disabled or read-only fields.

Visual impairments can also be related to color blindness or the way the brain processes images (e.g., dyslexia).
