In this exercise, you will create a simple bug-reporting application. The focus, at this stage, is to create a preliminary application that identifies the basics of how to make the program you need. To start out, here is a bullet-point list of what you will be doing: Get the tester s name, the application s name and build number, the date the bug is reported, the bug description, and the name of the file that stores the bug report. Collect all the data and format it into a string before you save it. Open a file and save the data. 1. Create an initial interface design on paper. Figure 6-1 shows the design we came up with for a simple bug-reporting application. While your application can look different, please do not add additional items at this stage.

Figure 6-1. Bug Reporter form 2. Now that we have created a preliminary design, create a new .NET project named BugReporter. 3. Although Visual Studio always starts you off with a form called Form1, please rename this form to BugReporterForm.vb or BugReporterForm.cs, depending on the language you are using. You can change the name of the file to match the new class name by right-clicking and renaming it in Solution Explorer (see Figure 6-2): Rename in VB .NET, and Refactor Rename in C#.

Note Using one of the new features in Visual Studio 2005, you could have also gone to the code view of the form, right-clicked on the name of the class, and chosen to Rename in VB .NET or Refactor Rename in C# from the pop-up menu. The problem is that this option does not change the filename. Choosing to rename the code file instead is convenient in this case, but there are times when one code file will contain two or more classes. If a second class is in the same file, then the second class would not be renamed. So, you would have to manually change it yourself. Either way works, though and in the end, it really does not matter too much. When Visual Studio 2005 compiles your code, all the code files are combined into an .exe or .dll output file.

CHAPTER 6 CREATING TESTWARE COMPONENTS
Note We are using a Comma Separated Value (CSV/.csv) file because it is so useful in actual production
applications. CSV files are really just text files. So, you can open them with Notepad if you like. Still, they are more useful when working with spreadsheet programs (like Microsoft Excel) or database programs (like Microsoft Access or SQL Server). For instance, if you have Excel installed on your computer, you will notice that double-clicking on the CSV file opens a new spreadsheet.
