When testing your web page designs, it is important that you take every part of the process seriously. You should document most of the process by creating screenshots for every browser and test subject, listing your expected results, and adding notes to explain each problem individually.
It is also recommended that you note the date of the test, along with the ‘revision id’ of the version control system the test resides on. Using a version control system is a bit more effort, but this effort is well worth it if you want to prevent accidentally deleting something, overwriting the incorrect code, or for cases in which your work machine breaks down irreparably.
As for the test itself, if the test indicates that something is in need of repair, you should not only make the necessary modifications, but you should also perform another test afterwards. Remember to note any modifications performed, along with the code. These steps should be repeated until you believe your deign is sufficient in terms of all tested browsers. Finally, it is recommended that you also test for cases in which certain features on your website are not available to the viewer, such as Adobe Flash or Java Script. This is another opportunity to apply the principles of progressive enhancement.
Issues While Testing
At times, a testing session may continue in non-progressive circles and get stuck. This may be due to the design’s complexity, the strict requirements, or the various browsers chosen to test. In many instances, it is a combination of all these issues.
If the problem resides in the IE, you can use conditional comments to load a custom style sheet for the troublemaker. Besides this, certain software systems allow you to search for different browsers and serve separate styles, which could also help the situation. If you are unsure of the issues, you can research it online to find others who may have posted how to solve the issue.
Testing Additional Changes
The key to all of these processes is estimating which changes will have affects first, and then concentrating your testing in these areas. In order to figure this out, you should draw from your knowledge of HTML and CSS, along with the history of previous changes you have made during the project. Should you be aware that a certain change is not supported by a browser, or that it may appear differently, this is always an opportunity to test it first. This practice applies to new technology as well.

As a general practice, the more structured and organized you are during your testing, the less time you will have to waste searching for issues during the initial implementation, as well as further down the line when you have to perform maintenance. Many test case procedures seem tedious at first, but effective management of tasks makes the process productive. If you follow through with all procedures properly, your web page design will look good on every target browser. Your target audience will be able to appreciate the work, and you will have an easier time making alterations in the future.
