This chapter explained in detail about how web performance testing works, and how the recording of web tests takes place for the web applications. We have learned the usage of the different properties of web performance tests including copying the tests, cleaning the unwanted recorded requests, and extracting the details from the request whether it has Form POST parameters or QueryString parameters. This chapter also explained about setting the rules for validating and extracting the details based on certain conditions. The current version of Visual Studio has brought in a few new features, such as adding loops and adding conditions to the requests which are very useful for tests. Transactions are useful to group a set of similar requests and give it a name. We have learnt how to include different data sources and map the fields to the data source fields and also parameterize fields and web server names.

The final section of this chapter explained about executing the tests and collecting the results. Some more advanced web testing features using custom code in tests are covered in detail in the next chapter. The advanced web testing features comprise generating code from the web test recording and then customizing the code as per the need. The other features include debugging and adding custom rules to the code.
