Read ... would include a test where x is equal to 5, forcing the condition to evaluate as true. A second test where x is greater than 5 would force the conditional expression to evaluate as false. With two tests we are able to evaluate both the true and false outcomes of the conditional clause, but these two tests do not adequately test the relational operator. Testing the relational operator requires an additional test where x is less than 5. Although this third test seems self-evident, incorrect usage of relational operators is one of the leading causes of boundary class defects. Decision tests also do not effectively evaluate control flow of a compound conditional clause. For example, the looping structure in the SimpleSearch function contains two conditional clauses or subexpressions. Decision tests are designed to evaluate compound conditional clauses to their true and false outcomes regardless of the number of conditional expressions. So, if we pass a string of ABC as the myString parameter, and a character of B as the myCharacter parameter to the SimpleSearch function, we can evaluate both the true and false outcomes of the looping structure. However, we didn't adequately evaluate the false outcome of the conditional subexpression that evaluates the index against the length of the string array. For adequate testing of compound conditional clauses with multiple conditional subexpressions, we use a slightly different structural technique called condition testing. // Do the prolog. SNAPPROLOG ( stInitialCtx ) ; eRet = eDUMP_SUCCEEDED ; // Check the string parameter. ASSERT ( FALSE == IsBadStringPtr ( szDumpName , MAX_PATH ) ) ; if ( TRUE == IsBadStringPtr ( szDumpName , MAX_PATH ) ) { eRet = eBAD_PARAM ; } if ( eDUMP_SUCCEEDED == eRet ) { // Zero out the final context structure. ZeroMemory ( &stFinalCtx , sizeof ( CONTEXT ) ) ; // Indicate I want everything in the context. stFinalCtx.ContextFlags = CONTEXT_FULL CONTEXT_CONTROL CONTEXT_DEBUG_REGISTERS CONTEXT_FLOATING_POINT | | | ; // Get all the groovy context registers and such for this // thread. bRetVal ,&stFinalCtx); = GetThreadContext ( GetCurrentThread ( ) This chapter focused on XML serialization. For a more thorough coverage of object serialization in general, look at Programming Visual Basic .NET by Francesco Balena (Microsoft Press, 2002). 11 of that book provides a comprehensive explanation of run-time object serialization in the .NET Framework, including XML serialization. SOAP was also repeatedly mentioned in this chapter. A good introduction to SOAP that successfully weds philosophy and technology can be found in Don Box's article "Young Person's Guide to the Simple Object Access Protocol: SOAP Increases Interoperability Across Platforms and Languages," in MSDN Magazine, March 2000. 421 Sometimes control flow through a function depends on the outcome of multiple conditional clauses. But rather than writing cascading conditional clauses, developers can often simplify the function by writing a single conditional clause composed of multiple Boolean subexpressions that are separated by logical AND or logical OR operators. For example, the IsNumberBetweenMinAndMax function checks for a number between minimum and maximum values. This implementation uses two simple conditional clauses to return either a true or false output. IsNumberBetweenMinAndMax() Function ASSERT ( TRUE == bRetVal ) ; if ( TRUE == bRetVal ) { COPYKEYCONTEXTREGISTERS ( stFinalCtx , stInitialCtx ) ; // instruction // that got us into this function. All the rest of the // registers are set up before the call so I'll ensure the // instruction pointer is set that way too. UINT_PTR dwRetAddr = (UINT_PTR)_ReturnAddress ( ) ; bRetVal dwRetAddr ); = CalculateBeginningOfCallInstruction ( Get the return address and hunt down the call ASSERT ( TRUE == bRetVal ) ; if ( TRUE == bRetVal ) { // Set the instruction pointer to the beginning of the // call instruction. stFinalCtx.Eip = (DWORD)dwRetAddr ; // Call the common function that does the actual write. eRet , szDumpName , = CommonSnapCurrentProcessMiniDump ( eType A good source for learning about SOAP in general terms and not specifically from a .NET Web service perspective is Understanding SOAP, by Kennard Scribner and Mark Stiver (SAMS, 2000). For an in-depth reference discussing both SOAP and Web services from a .NET Framework angle, try Building XML Web Services for the Microsoft .NET Platform, by Scott Short (Microsoft Press, 2002). private static bool IsNumberBetweenMinAndMax (int number) { int minValue = 1; int maxvalue = 10; if !(number < minValue) { if !(number > maxValue) { return true; } } return false; } &stFinalCtx ); } else { eRet = eGETTHREADCONTEXT_FAILED ; } } } // Do the epilog. SNAPEPILOG ( eRet ) ; 512 The Microsoft NET Framework infrastructure for remoting is the set of system services that enable NET applications to communicate and exchange data and objects In this chapter and 13, you'll find an annotated overview of the two technologies that constitute the NET answer to the universal demand for a seamless and effective mechanism for building distributed and interoperable applications: NET Remoting and Web services Before we begin our technical examination of the NET Remoting architecture, a broader perspective is necessary to understand how NET Remoting that is, a nonXML technology fits into a book about XML Interprocess Communications in the NET Framework Web services and NET Remoting are distinct, stand-alone technologies that share a common root but have different sets of features and, more important, different goals Both Web services and NET Remoting let you publish functions over a network and handle incoming calls. } // I had to pull this out of SnapCurrentProcessMiniDumpA/W as it's naked // so can't use SEH. BOOL CalculateBeginningOfCallInstruction ( UINT_PTR & dwRetAddr ) { BOOL bRet = TRUE ; // Protect everything inside exception handling. I need to be extra // careful here as I'm reading up the stack and could possibly bump // off whacking // the possible __try { BYTE * pBytes = (BYTE*)dwRetAddr ; if ( 0xE8 == *(pBytes - k_CALLNEARBACK) ) { dwRetAddr -= k_CALLNEARBACK ; } else if ( 0xFF == *(pBytes - k_CALLFARBACK) ) { dwRetAddr -= k_CALLFARBACK ; } else { bRet = FALSE ; } } __except ( EXCEPTION_EXECUTE_HANDLER ) { bRet = FALSE ; } return ( bRet ) ; } the top. As I when don't you want call SnapCurrentProcessMiniDump it, I've got to eat any But we can rewrite the two simple conditional clauses using a logical AND operator to separate the two Boolean expressions in this function. The advantages to refactoring the code as illustrated in the following example include the reduction of lines of code, increased maintainability index, and reduced number of blocks. In the preceding function, the number of decision tests is three, and in the following refactored code, the number of condition tests is also three if we assume short-circuiting.
