In this chapter, we will have a look at some of the things that you cannot do with Selenium, and some of the things that you should not do with Selenium. We will have a look at some solutions that will work around its limitations. The topics we will cover in this chapter are:

• File downloads
• Checking network traffic
• Load testing

The first topic we are going to look at is something that I regularly end up talking about—downloading files with Selenium.
