An excellent return on investment for large-scale test automation requires integration in all stages of the automation, check-in, and bug tracking systems A successful solution greatly reduces the need for manual intervention analyzing test results and failures Another use of AFA is in analyzing trends in test failures For example, analysis can indicate that parameter validation errors contributed to 12 percent of the test pass failures over the last six months, or that UI timing issues contributed to 38 percent of the test pass failures over the last six months This data can be used effectively to understand and target risk areas of the product AFA in Action: Three Short Stories Use of an AFA system delivers numerous additional benefits The following scenarios describe some of the possibilities that occur in such a system Bob the Developer has just checked in the fix for bug ID 4321.

Table 7-3: XSLT Instructions for Control Flow Instruction Description Applies the internal template only if <xsl:if test=" "> the specified XPath expression </xsl:if> evaluates to true. Similar to the C# switch statement; <xsl:choose> <xsl:when test=" "> represents a multiple-choice </xsl:when> statement. Each test is expressed <xsl:otherwise> using an <xsl:when> statement, </xsl:otherwise><xsl:choose> while the <xsl:otherwise> element represents the default choice. The statement evaluates all the <xsl:when> blocks until the test expression returns true. When that happens, the corresponding template is applied. If no test is successful, the <xsl:otherwise> template is invoked. Although this list of commands lacks a for statement, you can still realize a loop that runs a specified number of times by using the XPath position function. Of course, position returns the index of the current context node and is not a general variable counter. On the other hand, XSLT instructions are designed to work on XPath nodesets, not to arrange general-purpose programs. Layout Instructions A typical task for an XSLT script is the creation of new elements and attributes. Sometimes attributes and node elements can be hard-coded in script; sometimes this is just impossible to do. The XSLT statements listed in Table 7-4 let you programmatically create layout elements. Table 7-4: XSLT Instructions for Layout Instruction <xsl:element name = " " namespace = " "> </xsl:element>

Table 7-8: Calling Conventions Calling Convention Argument Passing Stack Maintenance 280 Name Decoration Notes

When checking in the code to the source code management (SCM) system, bug 4321 was automatically resolved in the bug database The failure analysis system notes that the bug is marked as fixed and automatically moves all of the tests that were failing because of this bug to the front of the automation queue so that the verification of the fix can occur early in the test run Several test cases have been failing for the past few weeks because of bug 7734 On today's automated test pass, the tests failed again, but the failure analysis system noted that two of the tests failed differently from how they had in the past A new bug is automatically created The bug contains information about the failure as well as a link to bug 7734.

Table 2-1: Public Properties of the XmlReader Class Property Description Prefix Gets the namespace prefix associated with the current node QuoteChar Gets the quotation mark character used to enclose the ReadState Value XmlLang XmlSpace value of an attribute Gets the state of the reader from the ReadState enumeration Gets the text value of the current node Gets the xml:lang scope within which the current node resides Gets the current xml:space scope from the XmlSpace enumeration (Default, None, or Preserve) When you read any sort of documentation about XML, you are usually bombarded by a storm of similar-looking acronyms: URI, URL, and URN Let's review these terms A Uniform Resource Identifier (URI) is a string that unequivocally identifies a resource over the network There are two types of URI: Uniform Resource Locator (URL) and Uniform Resource Name (URN).

Table 7-8: Calling Conventions Calling Convention __cdecl Argument Passing Right to left. Stack Maintenance Caller removes arguments from the stack. This calling convention is the only one that allows variable argument lists. Callee removes its own arguments from the stack. Name Decoration Underscore prefixed to function names, as in _Foo. Notes The default for C and C++ functions.

Underscore prefixed to function name, and @ appended followed by the number of decimal bytes in the argument list, as in _Foo@12. An @ is prefixed to the name, and @ is appended followed by the number of decimal bytes in the argument list, as in @Foo@12. None.

Finally, an automatic scan of recent code changes takes place, and the bug is assigned to the developer who most likely caused the new failure to occur This morning Jane the Test Manager saw that the latest test pass had 48 new failures The AFA system identified the same root cause for all 48 of the failures and noted the failure pattern in the bug report With AFA, the team can focus on new issues as they occur Much of the risk in analysis of test results is in losing important variations in the noise of expected variations When investigating a series of failures it is natural (and common) to make evaluations such as "This test point failed last week; this week's failure is probably the same as last week's.

A URL is specified by the protocol prefix, the host name or IP address, the port (optional), and the path A URN is simply a unique descriptive string for example, the human-readable form of a CLSID (the 128bit identifier of a COM object) is a URN A bit misleading is the fact that URNs are often created using URLlike strings This regularly happens with XML namespaces, for example The reason for this practice is that a URL has a high likelihood of being unique, especially if you use a path within your company's Web site An XML reader can pass through several different states All the possible states are defined by the ReadState enumeration and are listed in Table 2-2.

Used automatically by C++ class methods unless you specify standard call. COM methods are declared as standard call.

Table 7-8: Calling Conventions Calling Convention naked Argument Passing Right to left. Stack Maintenance Caller removes arguments from the stack. Name Decoration None. Notes Used when you need custom prolog and epilog.

" An AFA system is capable of removing the tedium from test pass analysis and removing avoidable analysis errors by using rules of analysis when deciding whether a failure has been previously observed Furthermore, these rules are not relaxed because of familiarity with the tests or frequency of the observed test point failure mentioned in 9, "Managing Bugs and Test Cases," a test point is an instantiation of that test case in a unique environment..

The ReadState property contains a ReadState enumeration value and is expected to return the current state of the reader, but actual implementations of a reader class must ensure that the property always holds the correct value Table 2-2: Reader States State Description Closed The reader is closed EndOfFile Error Initial Interactive The end of the file has been reached successfully, but the reader is not yet closed A critical error occurred, and the read operation can't continue The reader is in its initial position, waiting for the Read method to be called for the first time The reader is open and functional 23.

Changing the calling convention is done as part of the function declaration and definition For example, the following shows where to place the calling convention There are also compilation switches to CLEXE that you can specify to change the default calling conventions for the compile, but I would recommend against using those switches and explicitly specify the calling convention on each function so there is no possible confusion for maintenance programmers // Declaring a __stdcall function: void __stdcall ImAStandardCallFunction ( void ) ; If you've never been exposed to the different calling conventions, you might wonder why the different types exist The differences between the C declaration and the standard call are subtle In a standard call function, the callee cleans up the stack, so it has to know exactly how many parameters to expect Therefore, a standard call function can't be a variable argument function such as printf.

The BaseURI property actually returns the URL of the node Normally, the URL of a node more generally, the URI is bound to the resource name, be it a local file, a networked document, or a Web document In these cases, the BaseURI property simply returns the URL-styled name of the resource The following are examples of values that would be returned under these circumstances: file://c:/myfolder/mydocxml http://wwwcpandlcom/myfolder/mydocxml An XML document can result from the aggregation of various chunks of data entities, schemas, and DTDs coming from different network locations In these cases, the BaseURI property tells you where these nodes come from If the XML document is being processed through a stream (for example, an in-memory string), no URI is available and the BaseURI property returns the empty string Base Methods of XML Readers Table 2-3 lists the public methods exposed by the XmlReader class.

Microsoft test teams use massive labs filled with desktop computers and walls of rack-mounted systems. The computers are a finite resource and are in demand for use as build machines or for nightly or weekly manual and automated test passes. Microsoft Hyper-V (formerly known as Windows Server Virtualization) is quickly gaining ground as an alternative that is allowing test teams to use virtual machines. (The most simple definition of a virtual machine, or VM, is an implementation of a computer that runs as a program on a host system.) Hypervisor-based virtualization (like Hyper-V) has much better performance and security than does hosted virtualization (where the VM runs as a program inside the host operating system).
