necdotal evidence indicates that functional programming frequently leads to a substantially reduced bug rate for good programmers This is primarily because programs built using functional techniques tend to be highly compositional, building correct programs out of correct building blocks Functional programming style, moreover, avoids or substantially reduces the use of side effects in the program, one property that makes programs more compositional However, debugging and testing are still essential activities to ensure that a program is as close as possible to its specifications Bugs and misbehaviors are facts of life, and F# programmers must learn techniques to find and remove them As a result, software testing is an important activity when developing large systems Tests are initially carried out by simply writing small programs and interactively running them, but then a larger infrastructure quickly becomes necessary as a system grows and as new functionalities must preserve the existing ones.

The actual value of the __VIEWSTATE hidden input is hashed and then encrypted by the Framework before it is sent to the browser The Framework does the encryption for you to secure the value and to prevent a malicious user from posting a spoofed value to the server, possibly tricking an application into performing work it would not normally do The algorithm for hashing the value has changed from version 11 to version 20 of the Framework We ll take a look at that in the next section The new algorithm produces a smaller string for encryption, resulting in a smaller ViewState size overall There are a few different types of encryption you can use You can choose from SHA1, MD5, or Triple-DES The key used for the encryption and decryption of the data exists on the web server.

In this chapter, we will discuss how you can perform testing with F# using F# Interactive, using the debugging facilities provided by Visual Studio and the NET infrastructure, and using the NUnit framework for unit testing A widely adopted debugging technique is the do-it-yourself-by-augmenting-your-programwith-printf approach However, this is a technique that suffers from several problems and, although still useful, should not be the only technique you are prepared to apply to the complexities associated with program testing and debugging For testing, there are several strategies to test programs and ensure that they behave as expected, and the testing theory developed by software engineering has introduced several techniques used every day in software development In this chapter, we focus on three aspects of program debugging and testing with F#: Using the Visual Studio debugger and the .

NET debugging framework Using F# Interactive for testing and debugging Doing unit testing using NUnit, a freely available framework for unit testing Alternative tools for debugging and unit testing are available, such as the NET debugger that ships with the NET Framework and the testing framework included in the Team Edition of Visual Studio The concepts behind these tools are similar to those presented here, and the techniques discussed in this chapter can be easily adapted when using them All these techniques.

Attribute Weight Properties Attribute weight properties allow you to set weights on certain attributes of a connection in the connection cache. If the property ClosestConnectionMatch is set to true, then these weights are used to get a closest match to the connection you request. We will look at these properties along with this feature in more detail in the section Using Connection Attributes and Attribute Weights (10g Only). The ValidateConnection Property If you set this property to true, the cache manager tests for validity each connection to be retrieved from the database. The default value is false.

The Framework does the encryption not only for ViewState data, but also for the value of an authentication ticket cookie when using Forms-based authentication as well as to protect session data when it s out of process Since there s no facility to change or add items to ViewState from the client, there s no need for the client to ever be able to read the value The key s sole purpose is to restore state when it s posted back to the server So the server uses a key to encrypt the value, it s sent to the client (where it s truly meaningless) and then it s posted back to the server, where it s unencrypted and used to restore the state of any controls that put values into ViewState when first rendering.

Once an application is done using a connection, the application closes it using the close() method on the connection. There is another variant of this method that we will discuss in the section on Using Connection Attributes and Attribute Weights (10g Only).

and tools are very helpful, but it is important to remember that these are just tools and you must use them in the appropriate way.
