TestArchitect Tutorial Part 3: Extending TestArchitect Lesson #11: Creating Excel reports using TAUtilities Creating a summary report in Excel

 Implementing the interface

Implementing the interface

In this topic, the procedure generateMethod(), which interfaces with the TAUtilities APIs, is implemented.

Before proceeding:At this point, your Excel spreadsheet should be created, with a Generate button and a macro attached to it. The macro code is defined in the Creating the macro in Microsoft Excel topic.

You will now create the code for the generateMethod() procedure, which implements the interface to TAUtilities.

1. In the generateMethod() procedure, store the input parameters in cells $B$1 thru $B$7 into their respective variables, declared previously in step 4:

   'Get server information
   g_server = Trim(Cells(1, "B").Value)
   g_serverPort = val(Trim(Cells(2, "B").Value))
   g_repository = Trim(Cells(3, "B").Value)
   g_project = Trim(Cells(4, "B").Value)
   g_username = Trim(Cells(5, "B").Value)
   g_password = Trim(Cells(6, "B").Value)
   g_folder = Trim(Cells(7, "B").Value)
   

   Note:

   The Trim() method ensures that returned strings have no leading or trailing spaces.

   The Val() method returns the repository server’s port number as a numeric value.

2. Returned information is to be reported starting at row 18 of the worksheet. Hence, the row variable, also declared in step 4, is assigned a value of 18.

   row = 18
   

3. Create a Repository type object.

   'Create Repository type object
   Set repo = CreateObject("TAUtilities.Repository")
   

4. Note:

   The Repository type object has a method called Connect(). This is used to set up a connection to the TestArchitect repository. Connect() needs the following arguments:

   • server IP address or hostname,
   • server port address, and
   • repository name.

   If the connection is successful, the Connect() method returns a value of 1.

   Enter the following code lines:

   'Set up connection to TestArchitect repository
   If repo.Connect(g_server, g_serverPort, g_repository) = 1 Then
       ‘To-be-implemented
   End If
   

5. Log on to the specified repository with the Login() method.

   The ‘To-be-implemented line above can now be replaced with the login code. The Login() method requires username and password arguments. If the logon succeeds, this method returns a value of 1.

   'Log on to the specified repository
   If repo.Login(g_username, g_password) = 1 Then
       ‘To-be-implemented
   End If
   

6. To access objects in a specified TestArchitect project within a repository, the getProject() method is used.

   The ‘To-be-implemented line below the call to the Login() method can now be replaced with the following call to getProject(). Note that getProject() requires one argument, the name of the project.

   'Access objects in a TestArchitect project
   Set sProject = repo.getProject(g_project)
   

7. Before attempting to use it, validate the format of the test module folder path as it was entered into the Excel cell.

   The path is currently stored in the variable g_folder. It’s a valid path if one of the following is the case:

   • g_folder is empty
   • g_folder’s contents begin with the format "/" & g_project & "/Tests". For example, Car Rental/Tests/Action-based Testing Basics/, where, Car Rental is name of the project, Tests is the tree node on TestArchitect explorer tree, and Action-based Testing is the desired test module folder.

   'Validate the format of the test module folder’s path
   If g_folder = "" Or g_folder = "/" & g_project & "/Tests" Then
       Set TestFolderList = sProject.GetTestFolders(1)
       Set testModuleCollection = sProject.GetTestModules(1)
       WriteCell row, 1, "/" & g_project & "/Tests/"
       flag = 1
   Else
       Set atestFolder = sProject.GetTestFolder(g_folder)
       WriteCell row, 1, g_folder
       If atestFolder Is Nothing Then
           MsgBox "' " & g_folder & " '" & " is wrong folder path! Please check again"
       Else
           Set testModuleCollection = atestFolder.GetTestModules(1)
           flag = 1
       End If
   End If
   

   The method getTestFolders(1) and GetTestModules(1) returns recursively a collection of the test module folder TestFolderList object, and the test module testModuleCollection object.

   Important:
   The isRecursive parameter belonging to getTestFolders() and GetTestModules() only accepts the following boolean values (learn more):
   • Microsoft Component Object Model (COM):

     • 0: Gets project items at the top level only.

       Note:
       If an invalid value is specified, the value of 0 is used by default.

     • 1: Gets project items recursively at all levels.

   • Java:
     • false: Gets project items at the top level only.
     • true: Gets project items recursively at all levels. The macro writes the test module folder path into cell A18 by calling the method WriteCell()

   When the test module’s path validation is complete, the variable flag is set to a value of 1.

8. Once flag is set to the value of 1, the following code exports the data into the given cells.

   If flag = 1 Then
       'Get the number of items in the test module
       asize = testModuleCollection.getSize() 
   
       'Output the total numbers of test modules
       WriteCell 13, 2, asize 
   
       'Export further information starting from the cell with row 19
       row = row + 1 
   
       For i = 0 To asize – 1
           Set testModuleItem = testModuleCollection.getItemAt(i) 
   
           'Output test module's name
           WriteCell row, 1, testModuleItem.getName() 
   
           'Output test module's description
           WriteCell row, 2, testModuleItem.getDescription() 
   
           'Output test module's assigned user
           WriteCell row, 5, testModuleItem.getAssignUser() 
   
           'Output test module's author creating test module
           WriteCell row, 6, testModuleItem.getCreatedBy() 
   
           'Output test module's date of creation
           WriteCell row, 7, testModuleItem.getCreationDate() 
   
           'Output test module's recent result
           WriteCell row, 8, testModuleItem.getRecentResult() 
   
           row = row + 1   
           Next
   End If
   

   In the above code, the number of items in the test module testModuleCollection object are retrieved with the call to the getSize() method. WriteCell 13, 2, asize exports the total number of test modules into cell B13.

   Then name, description, assigned user, author, date of creation, and recent result of each test module is also reported in the specified cells in consecutive rows, one row per test module.

9. The following code line disconnects the connection:

   'Terminate the connection
   repo.Disconnect
   

10. To handle the possibility an error occurring in any of the TAUtilities functions, use the static getLastErrorMessage() method of the Repository class to catch the most recent exception message.

    MsgBox repo.getLastErrorMessage
    

In summary, the macro code in its entirety should resemble following:

Dim g_server As String
Dim g_serverPort As Long
Dim g_repository As String
Dim g_project As String
Dim g_username As String
Dim g_password As String
Dim g_testpath As String
Dim atestFolder
Dim testModuleCollection
Dim flag As Long
Dim row
