Create an input matrix of common or probable scenarios and historical failure indicators. 3. Create an input model file of the variable states for each parameter. 4. Customize the model file to exclude mutually exclusive variable states or invariant parameters. 5. Apply all input files to the PICT tool. 6. Review the tool output. 7. Refine and customize the model file if necessary. 8. Reapply all input files to the PICT tool. 9. Revalidate output. 10.Execute tests. You can examine each step in sequence to understand how to apply this technique correctly on a relatively simple simulation. Say you are testing a simple font dialog box such as the one shown in Figure 5-5. This dialog box lets the user choose one of four possible fonts, a font style of bold and italic, font effects of strikethrough and underline, font color (black, white, red, green, blue, or yellow), and font size (1-1,638 including half sizes). The total number of combinations for exhaustive testing is 1,257,600 (assuming all font size values are tested). Testing all combinations might not be possible or feasible, so you must select a reasonable set of tests that are effective in reducing overall risk. vb.net code to extract text from pdf: C# / VB .

You need to keep in mind the following drawbacks when you're using C++ exception handling First, it doesn't handle your program crashes automatically Second, C++ exception processing isn't free The compiler might do a great deal of work setting up and removing the try and catch blocks even if you never throw any exceptions, so if you're working on performance-sensitive code you might not be able to afford that much overhead If you're new to C++ exception handling, MSDN is a great place to start learning about it Avoid Using C++ Exception Handling Probably one of the most consistently confusing issues that comes up for development shops in my company's consulting business is the issue of C++ exception handling Developers have wasted more effort on C++ exception handling problems than on anything else (except memory corruptions) when it comes to Windows development. vb.net read pdf to text Parsing PDF Files using iTextSharp (C#, .

Figure 5-5: Simple font dialog box illustrating directly dependent and semicoupled parameters. First, identify the interdependent parameters. In this example, the directly dependent parameters are font type and font styles because some font types cannot be bold only or italic only but might be bold and italic or bold or italic, or use no style at all. The font size, color, and effects are semicoupled parameters because they apply to all font types and affect the output accordingly. After you identify the interdependent parameters, you must define the variable states for each parameter. The variable states for font type are Arial, Tahoma, Brush Script MT, and Monotype Corsive. The font style and font effects each have two parameters (bold and italic, and strikethrough and underline) and each parameter has two variable states (select and clear). The font color uses six colors (black, white, red, green, blue, and yellow). There are 3,275 possible values for font size. It might not be reasonable to test all values, so you can construct equivalence ranges of values and randomly select one value from each ECP subset when that subset range is selected. So, for the font size parameter define five variable states using equivalence class subsets of Small (font sizes 1 9.5), Nominal (font sizes 10 12), Large (font sizes 12.5 72), Extra large (font sizes 72.5 XmlSerializer(Type, XmlRootAttribute) XmlSerializer(Type, XmlAttributeOverrides, Type[], XmlRootAttribute, string) Based on all the horrific situations we've resolved, my recommendation is to avoid C++ exception handling because your life will get infinitely simpler and your code will be easier to debug The first problem with C++ exception handling is that it isn't a clean feature of the language In many ways, it looks grafted on and unfinished The fact that we don't have an ANSI standard class that contains information about an exception means that there's no consistent way of handling generic errors Some of you might be thinking about the catch (..) construct as the standard approved catchall mechanism, but in the next section I'll permanently scare you off from ever using that construct again. C++ exception handling is also one of those technologies that looks great in theory but breaks down the minute you implement anything more than "Hello World!" Repeatedly I've seen completely insane situations on teams where someone becomes enamored with C++ exceptions and starts implementing tons of them in his code This forces the rest of the team to deal with C++ exception handling across the application, even though very few developers can deal with the ramifications of designing and using them What invariably happens is that some code forgets to catch some random unexpected exception, and the application goes down Additionally, the maintenance nightmare of trying to extend code that mixes return value failures as well as C++ exceptions means that many companies find it better to throw out the code and start again, thus massively increasing their costs. Let's review the code necessary to set up and use an XML serializer class: [Serializable] public class Employee { protected int m_ID; public int ID { get {return m_ID;} } public string FirstName; public string LastName; public string Position; public int[] Territories; 393 1638), and Half sizes (font sizes 1.5 1637.5) to ensure that you force at least one test combination with a font size that is not an integer value. By creating equivalent class subsets of font size ranges, the test designer gives greater flexibility to the tester (or well-designed test automation) to select a test value in the specified range for a given combination. In this example, partitioning the range of font sizes into equivalence class subsets also eliminates hard-coded test values, which unnecessarily restrict the test data to a very small set of data values, which might or might not be interesting values to include in tests. After you have thoroughly analyzed the features to determine which parameters are interdependent and have decomposed the variable states for each parameter to select the appropriate variables to test with, you can create a BC matrix, as shown in Figure 5-6. The BC matrix is important because studies have demonstrated that the inclusion of a base choice matrix in conjunction with higher levels of n-wise tests increases the likelihood of exposing a greater number of potential defects resulting from parameter interaction, and pair-wise or n-wise combination tests might not necessarily include BC combinations. The BC matrix generally defines the most common variable state combination, and then changes the variable state for each parameter one at a time while holding the other parameter variable states to the original value until all variables are tested at least once. Many people throw (pun intended!) out the argument that the best reason for using C++ exceptions is that developers never check return values from functions Not only is this a 462. public Employee() { m_ID = -1; } public Employee(int empID) { m_ID = empID; } public override string ToString() { return LastName + ", "+ FirstName; } } This class has one read-only member (ID), a couple of constructors, and a protected member. To begin, let's use the simplest constructor and see what happens: Employee emp = new Employee(1); emp.LastName = "Esposito"; emp.FirstName = "Dino"; StringWriter writer = new StringWriter(); XmlSerializer ser = new XmlSerializer(typeof(Employee)); ser.Serialize(writer, emp); string xmlText = writer.ToString(); writer.Close(); The output generated is rather compact and does not include null and less than public fields, as shown here: < xml version="1.0" encoding="utf-16" > <Employee xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <FirstName>Dino</FirstName> <LastName>Esposito</LastName> </Employee> The read-only ID property is ignored, as are all protected members. In addition, public properties set to null are blissfully discarded. Caution If the class being serialized does not provide the default constructor, an exception is thrown and the class won't be processed further. The XmlSerializer class raises an InvalidOperationException exception stating that the class can't 394 Figure 5-6: BC combinatorial test matrix for MyFontDialog example. A common problem with many combinatorial testing tools is the inability of the tester to define highly probable combinations in the output. PICT overcomes this limitation with an important feature that allows the tester to define and pass in a tab-delimited file with seeded combinations as input into the tool. A tab-delimited input file with seeded combinations gives the tester greater control over specific combinations to test while still allowing the tool to determine the complete set of test variables for complete n-wise coverage. So, after completing the BC test matrix the next step is to identify any common customer combinations or combinations that might be especially problematic based on failure indicators that aren't defined in the BC matrix. You can list these combinations in a tab-delimited seed file that will be passed to the PICT tool and used as part of the output of test combinations, as shown in Figure 5-7. For example, if you know that a combination of the Arial font with a style of Bold and an effect of Underline and a large font size is commonly used by a large segment of customers, you can include that in a seed file. You might also assert that a combination of Tahoma font with Bold, Italic, Strikethrough, and Underline selected and a font color of Yellow and a small font size has historically resulted in erroneous outputs, so you will also specify this combination in the seed file. The seed file forces the PICT tool to include these combinations in the output and guarantees that highly probable and highly problematic combinations always get tested. itextsharp read pdf line by line vb.net How to read pdf line by line and fetch the data in c# - C# Corner
