The value of structural testing lies in the ability of the tester to critically analyze control flow through a function and design tests that ensure various control flow paths are executed at least once. In the following SimpleSearch function example, we can exercise all statements in this function with one test by passing a string argument of AB and a character argument of B to the function's input parameters. With one simple test, control flow would enter the while loop because the index variable is less than the length of the array, and the character variable passed to the function through the myCharacter parameter is not equal to the element in the array indicated by the current index value. In the while loop, we execute a statement to increment the index variable by 1 and loop back around to evaluate both conditional clauses in the while loop again. The value of the index variable is still less than the length of the array, but the second element in the array is the character B, which is equal to the myCharacter variable. The second conditional clause is true because the value of the index variable is less than the length of the array, so we enter this block and increment the value of index by 1 and assign it to the retVal variable. Finally, control flow exits the decision block and returns the value of the retVal variable to the calling function. So, with one simple test we are able to execute all statements in this function. However, no professional tester would be satisfied with one simple test of this function!

With SAX, the client application receives any data the parser is designed to push and can discard it if that result is of no interest The data is always sent, however The application has to build fairly sophisticated code to isolate the pieces of information it really needs (that is, the nodes of interest) and, more importantly, to add them to a custom data structure that represents the state XML readers tout the pull model, in which the parser is just one tool managed and governed by the caller application This model allows for more selective processing the application just skips over unneeded data and even for an optimized interaction In fact, the application puts data of interest directly in its final buffers rather than having the parser create and pass on temporary buffers. return ( _T ( "EXCEPTION_IN_PAGE_ERROR" ) ) ; case EXCEPTION_ILLEGAL_INSTRUCTION break ; vb.net read pdf line by line: Convert a pdf file into byte - CodeProject vb.net read pdf file itextsharp Read text from PDF using iTextSharp

For the first block test, we would pass this function a string A and a character A to the first and second parameters, respectively. This test would execute 9 of the 11 blocks, as illustrated in Figure 6-2. NET class named SaxParser: Public Class SaxParser Public ContentHandler As SaxContentHandler Public Sub Parse(ByVal file As String) Dim reader As XmlTextReader = New XmlTextReader(file) While (readerRead()) ContentHandlerProcess(readerName, readerNodeType) End While readerClose() End Sub End Class The SaxParser class has a property named ContentHandler that refers to a userdefined object in charge of processing the found nodes The Parse method parses the content of the XML document using a reader, and whenever a new node is found, the method calls the content handler The content handler class has a fixed interface represented by the following abstract class: Public MustInherit Class SaxContentHandler Public MustOverride Sub Process(_ ByVal name As String, _ ByVal value As String, _ 40 readerValue,. return ( _T ( "EXCEPTION_STACK_OVERFLOW" ) ) ; return ( _T ( "EXCEPTION_INVALID_DISPOSITION" ) ) ; ByVal type As XmlNodeType) End Class After the two classes have been compiled into an assembly, a client SAX application can simply reference and instantiate the parser and the content handler class. The world's simplest content handler class is shown here: Public Class MyContentHandler Inherits SaxContentHandler Public Overrides Sub Process(_ ByVal name As String, _ ByVal value As String, _ ByVal type As XmlNodeType) If type = XmlNodeType.Element Then MsgBox(name) End If End Sub End Class The SAX application initializes the parser as follows: Dim saxParser As New SaxParser() Dim myHandler As New MyContentHandler() saxParser.ContentHandler = myHandler saxParser.Parse(file) Of course, the parser discussed here is fairly minimal, but the design guidelines are concrete and effective. As an aside, consider the fact that in the client application, the content handler class and the form are different classes, which makes updating the user interface from the content handler class a bit complicated. Note The full source code discussed here is provided in this book's sample files. The application is named SaxParser. Figure 6-2: Block coverage results of first test. In the second test, we pass a string argument of A and a character argument of B to the function and execute 10 of the 11 blocks, as illustrated in Figure 6-3. Notice that this second test now executes the previously untested blocks, but also skips over one block that was exercised in the previous test. With these two simple block tests we can achieve 100 percent block coverage of this function. return ( _T ( "EXCEPTION_GUARD_PAGE" ) ) ; In 8, we saw the ExecuteXmlReader method exposed by the SqlCommand class in the SQL Server managed provider. The ExecuteXmlReader method executes a command against the database and returns an XML reader if the output of the command can be expressed as a well-formed XML document or fragment. Let's see what's needed to transform that output into an instance of a class. The following code is at the heart of the example. You call into a method, the method executes an SQL XML 411 return ( _T ( "EXCEPTION_INVALID_HANDLE" ) ) ; Figure 6-3: Block coverage results of second test. Modeling Control Flow Control flow diagrams (CFDs) are simply models of a function or a class. A CFD must have one entry point and an exit point. Between the entry and exit points of a function the CFD provides an abstract representation or model of the program's code to help a tester trace the control flow as it could traverse the various paths through a complex function. There are two basic types of CFDs, as illustrated in Figure 6-4. return ( _T ( "Microsoft C++ Exception" ) ) ; command, the data flows into the serializer, and an instance of a particular class is returned. Employee emp = LoadEmployeeData(empID); The following code shows the body of the LoadEmployeeData method: private Employee LoadEmployeeData(int empID) { // Create the serializer XmlSerializer ser = PrepareEmployeeTypeSerializer(); // Prepare the connection and the SQL command SqlConnection conn = new SqlConnection(NWindConnection); SqlCommand cmd = PrepareSqlCommand(empID, conn); conn.Open(); // Execute the command Employee emp = null; XmlTextReader reader = (XmlTextReader) cmd.ExecuteXmlReader(); // Deserialize the incoming data if(ser.CanDeserialize(reader)) emp = (Employee) ser.Deserialize(reader); else Console.WriteLine("Cannot deserialize"); // Clean-up reader.Close(); conn.Close(); return emp; } The serializer is tailor-made for the Employee class shown here: public class Employee { public string FirstName; public string LastName; public string Position; public DateTime Hired; } The SQL command used in our example is shown here: SELECT firstname, lastname, title, hiredate FROM employees 412 Figure 6-4: Control flow diagram examples A basic CFD uses typical flowchart symbols to model the function The basic CFD uses a rectangle to represent statements or blocks of statements, and a diamond to represent decisions or conditional clauses Basic CFDs are easier to read and understand by people unfamiliar with the function and essentially model the control flow step by step through process blocks and conditional clauses The simplified CFD uses circles to represent decision points in the function where control flow can change depending on the outcome of a relational condition The simplified CFD is a more abstract representation of the function because it does not explicitly model blocks of statements This level of abstraction is sometimes confusing at first, but it increases the efficiency of the modeling process. // Set up the symbol engine. DWORD dwOpts = SymGetOptions ( ) ; // Turn on line loading. SymSetOptions ( dwOpts SYMOPT_LOAD_LINES // Force the invade process flag on. BOOL bRet = SymInitialize ( GetCurrentProcess ( ) , NULL TRUE ASSERT ( TRUE == bRet ) ; g_bSymEngInit = bRet ; } } // Cleans up the symbol engine if needed void CleanupSymEng ( void ) { if ( TRUE == g_bSymEngInit ) { VERIFY ( SymCleanup ( GetCurrentProcess ( ) ) ) ; g_bSymEngInit = FALSE ; } } , ) ; | ) ; vb.net code to extract text from pdf Reading PDF content with itextsharp dll in VB .
