How to test your website before going live

Testing checklist is designed to pre-plan all the activities required to conduct a browser compatibility test. Developers and testers usually use it to make sure nothing is left behind. Below there are some aspects that should be checked.

Checklist covers 4 aspects: Preparation, Content, Layout and Functionality.

Preparation

Before going on the checklist you need to know what is browser compatibility testing, how to perform it and what browsers to test in. Answer the following questions:

  • Do you know what browsers are used by your target audience?
  • Are all those browsers and their versions available for testing?
  • What devices do you need to run these browser tests?

Content

When testing a product in different browsers, ensure your content is interpreted as intended:

  • All the images are displayed with proper sizes across browsers.
  • Implemented fonts work identically for every browser.
  • Audio files are available for every browser.
  • Content can be used in any browser version.

Layout

While some layout elements may not behave as expected in some browsers, it is necessary to check the following aspects before going live:

  • The layout is consistent across browsers.
  • All layout elements function as expected.
  • Responsive layout works in all browser versions.
  • Both animations and effects run smoothly and as it should.

Functionality

Be sure to keep the following points in mind when checking functionality of your product:

  • All features are usable in the targeted browser versions.
  • All integrations and third party services run as expected.
  • All forms and other dynamic interactions work identically across browsers.
  • All interactions work equally well with touch and mouse.

Preparation before live browser testing

The main purpose of testing is to check how the web resource displays and functions in a given browser or operating system. This usually involves running your website across browsers to validate whether any of the styles, layout, or functionality are different or inappropriate.

The visitors of your website can encounter browser compatibility issues.

The website should be cross-browser compatible to ensure the best user experience. You can't just start testing your product in various browsers without preparation.

Everyone knows: before going live, browser testing is a must. Testing is undoubtedly crucial, but proper preparation is equally important. So, take your time to determine the scope and amount of testing, do not forget to list out the targeted browsers and devices used by your audience.

Once done with preparation, the next step is to go through items from Content, Layout and Functionality groups of the checklist.

Browser compatibility testing checklist: content testing

Content available on your site should be understandable and well structured for each of the browsers. If you do not check the cross-browser compatibility of the resource, content is likely to be interpreted differently.

The following things may happen: images will not be displayed in their standard resolutions, fonts will become unreadable for the user. When do cross browser tests, make sure your audio and video files are working properly and images are optimized.

Browser compatibility testing checklist: layout testing

Layout testing is provided to verify all layout elements and layout itself are consistent regardless of the operating system and browser type. The page layout may break on devices with different resolutions. Therefore, you should test the site to ensure the layout matches the expectations of your design.

Therefore, you website can look differently in different browsers.

Check the alignment of data content on web pages, arrangement of elements, and the spacing between sections, fields, paragraphs, images, data content, and also verify you didn't miss out on elements presented in the mockup.

Take care of browser compatibility at the development stage. When it comes to cross browser compatibility issues and solutions, there are some rules that need to be adhered to. When developing a cross-browser compatible website do not forget to validate HTML and CSS, use CSS resets, check for Doctype. In this way, you will be able to avoid most of the issues related to site display.

Browser compatibility testing checklist: functionality testing

Functional testing is high on the website testing checklist. It ensures that every feature of your website works as it should.

For example, by testing functionality testers check if all forms and other dynamic interactions work consistently across targeted browsers, validate different functionalities like form submit and test navigation links. The functionality of your product plays an immense role and should not be neglected while testing.
