[edit] Getting Started

You must install the TestTrack SDK as part of your server installation. If you haven't done this, you'll need to run the TestTrack installer for the version you have installed. Once installed, there are 2 files of interest.

  • http://yourserver/cgi-bin/ttsoapcgi.exe - CGI Executable that all TestTrack SDK commands go through. It's not important to understand CGI, just know where this file was installed.
  • http://server/ttsoapcgi.wsdl - The WSDL file that defines the language you use when talking to the CGI executable. Anyone that uses the TestTrack SDK uses this wsdl, there is no need to generate a specific wsdl for your installation. Everything is genericized so that, no matter how you customize TestTrack, this one wsdl file will handle it.

If you are using Visual Studio 2008 you will need to edit the ttsoapcgi.wsdl before referencing it. The wsdl defines all date types as a simple object 'date'. But in C#, date is a complex DateTime object. Because the C# system.xml.serializable soap reflection importer does not have a complex type for 'date', it will throw an exception for the SoapElementAttribute.DataType property the first time you try to instantiate the ttsoapcgi object. To work around this problem, change all the wsdl-defined xsd:date to xsd:dateTime. [Be careful not to change the actual date field of the CEvent object, only its data type.]

Now you're ready to pull the wsdl into Visual Studio. Within your Visual Studio project, right-click the project and choose Add Web Reference. In the URL field, enter the address to your TestTrack SDK installation, something like:

http://myserver/ttsoapcgi.wsdl

Click Go. Visual Studio should find one web reference at that address. Change the web reference name to TTSoap then click Add Reference.

Finally, import the namespace and you're ready to roll.

using ProgramNamespace.TTSoap;
e.g. using MyApp.TTSoap;

An alternative method is to generate the stub code manually, from the wsdl. The downside is you'll have to do this each time you upgrade to a newer version of TestTrack.

[edit] Create a Connection

The TestTrack SDK requires authentication before you can retrieve and save data.

ttsoapcgi cgiengine = new ttsoapcgi();

// Set the URL, based on your SDK installation.
cgiengine.Url = "http://myserver/cgi-bin/ttsoapcgi.exe";

// Fetch a list of projects you have access to.
CProject[] aproject = cgiengine.getProjectList( "administrator", "");

// Or, build your own.
CProject project = new CProject();
project.database = new CDatabase();
project.database.name = "MyProject";
project.options = new CProjectDataOption[3];
project.options[0] = new CProjectDataOption();
project.options[0].name = "TestTrack Pro"; // add TTP functionality.
project.options[1] = new CProjectDataOption();
project.options[1].name = "TestTrack TCM"; // add TCM functionality.
project.options[2] = new CProjectDataOption();
project.options[2].name = "TestTrack RM"; // add RM functionality.

// Login.
long lSession = cgiengine.ProjectLogon( project, "administrator", "");

   ...do some stuff...

// When you're finished, log off.
cgiengine.DatabaseLogoff(lSession);

Things to Know:

  • You cannot login via the TestTrack SDK if you are already logged in via one of the TestTrack clients. It's best to use a dedicated account for your SDK scripting to ensure you'll always be able to login.
  • If you do not explicitly call DatabaseLogoff, your user will remain logged in until the TestTrack SDK times out. This could present a problem if you try to re-run the script inside that timeframe. It's important to use try/catch exception handling to ensure that an exception in your program doesn't skip logging you off.
  • The CProjectDataOption array governs what licenses you use and functionality you have access to. For example, you can't use a TestTrack TCM license if you don't specify one in the CProjectDataOption array.

[edit] Query Objects

There are two ways to retrieve data through the TestTrack SDK. You can explicitly call a getObject method or you can call the getRecordListForTable method.

[edit] getObject

Calling the get method on an object is useful when you know exactly which object you need. For performance reasons, this is not recommended when you want to extract data from multiple objects of the same type.

// retrieve defect #45, with attachments.
CDefect def = cgiengine.getDefect(lSession, 45, "", true);

// retrieve test case #312, with attachments.
CTestCase tCase = cgiengine.getTestCase(lSession, 312, "", true);

// retrieve requirement #23, with attachments.
CRequirement req = cgiengine.getRequirement(lSession, 23, "", true);

// retrieve requirement document #3, with attachments.
CRequirementDocument reqDoc = cgiengine.getRequirementDocument(lSession, 3, "", true);

[edit] getRecordListForTable

If you'd rather query multiple objects of the same type, similar to a SELECT statement in SQL, use getRecordListForTable. This method allows you to specify what data you want to retrieve and apply a filter to the results.

// #, summary, custom field, product and type
string[] astrFields = new string[] {"Number", "Summary", "My Custom", "Product", "Type"};
CTableColumn[] atc = new CTableColumn[astrFields.Length];
for (int i = 0; i < astrFields.Length; ++i)
{
   atcFetch[i] = new CTableColumn();
   atcFetch[i].name = astrFields[i];
}

// fetch all defects
CRecordListSoap rows = cgiengine.getRecordListForTable( lSession, "Defect", "", atcFetch);

When calling getRecordListForTable you must specify both the object type you want to query and an array of fields you want to retrieve. You can also optionally specify a filter that you've pre-configured in TestTrack.

All of this information can be hard-coded as shown in the previous example, or dynamically passed as shown below.

// What object types can I query?
CDatabaseTable[] adt = cgiengine.getTableList(lSession);

// What field data is available for a given object type?
CTableColumn[] atc = cgiengine.getColumnsForTable( lSession, adt[?]);

// What filters are available?
CFilter[] af = cgiengine.getFilterList(lSession);

Things to Know:

  • TableColumn elements use the field's Short Label value.
  • You can use getRecordListForTable to retrieve pretty much anything you can view in a list view column within the GUI clients.

[edit] Querying the Requirement Document

A Requirement Document is a collection of requirements. If you need a list of the requirements associated with a specific document you can use the getRequirementIDsForDocument() call.

//get a list of requirement numbers associated with Requirement Document #4

long[] reqs = cgiengine.getRequirementIDsForDocument(lSession, 4);

//Returns requirement numbers, not record ids.

[edit] Create Object

Adding an object is simply a matter of creating a new instance and calling the addObject method.

For example, to create a defect:

// Create the CDefect object.
CDefect def = new CDefect();
def.summary = "This is a new defect";
def.product = "My Product";
def.priority = "Immediate";

// Add the defect to TestTrack.
long lNewNum = cgiengine.addDefect(lSession, def);

Things to Know:

  • When setting drop-down list values, you must match exactly (case-sensitive) with an existing value in the drop-down list.
  • When setting date/time values, you must also set the set{FieldName} value to true.

[edit] Update Object

Before updating an object, you must first lock it for editing by calling editObject.

// Open defect #11 for editing.
CDefect def = cgiengine.editDefect(lSession, 11, "", true);

// Change the Priority.
def.priority = "Immediate";

// Save the defect changes
cgiengine.saveDefect(lSession, def);

// Or, you can release the edit lock w/o saving changes.
cgiengine.cancelSaveDefect(lSession, def2.recordid);

Things to Know:

  • You cannot edit an object that is being edited by another user. For example, if someone else had defect #11 open for edit in their client, the previous example would fail.
  • If you successfully lock a defect for editing, that lock remains until you save it, cancel the save or logout. You should use try/catch exception handling to ensure that you release the lock as soon as possible.

[edit] Update Custom Field

// Lock the defect for edit.
CDefect def = cgiengine.editDefect(lSession, 1284, "", false);

// Find and update the 'My Custom' custom field.
for (int i = 0; i < def.customFieldList.Length; ++i)
{
   if (def.customFieldList[i].name == "My Custom")
      ((CStringField)def.customFieldList[i]).value = "Testing";
}

// Save changes.
cgiengine.saveDefect(lSession, def);

Things to Know:

  • The customfieldlist array holds the base-class CField objects, which must be casted as appropriate before you can set a value. In the example, 'My Custom' is a text field so we casted to CStringField. See the TestTrack SDK Types page for a full list of supported field types.

[edit] Creating a defect with a custom field

When creating a defect with a custom field, it appears that you have to fill in all of the custom fields. Otherwise you get a "Well-formedness error". To do this:

CDefect def = new CDefect();
// ...fill in the other fields...

CField[] customFields = cgiengine.getCustomFieldsDefinitionList(lSession, "Defect");

// Fill in the "Customer" field (a little LINQ here):
CStringField customerField = (CStringField)customFields.First(f => f.name == "Customer");
customerField.value = "ACME";

def.customFieldList = customFields;
long recordId = cgiengine.addDefect(lSession, def);

[edit] Update Workflow State

TestTrack calculates state based on event history. This means you can't simply set a value to change state. Instead, you have to apply the necessary events to move the object into the desired state.

// Lock the defect for edit.
CDefect def = cgiengine.editDefect(lSession, 1284, "", false);

// Create the Fix event.
CEvent de = new CEvent();
de.name = "Fix";
de.resultingstate = "Fixed";
de.user = "System Administrator";
de.date = DateTime.Now;
de.fieldlist = new CField[1];
de.fieldlist[0] = new CDropdownField();
de.fieldlist[0].name = "Resolution";
((CDropdownField)de.fieldlist[0]).value = "Code Change";

// Add the event to defect's eventlist.
if (def.eventlist == null || def.eventlist.Length==0)
{  // No events, so we can just create a new list.
   def.eventlist = new CEvent[1];
   def.eventlist[0] = de;
}
else
{  // Append new event to end of existing list.
   ArrayList list = new ArrayList();
   for (int i = 0; i < def.eventlist.Length; ++i)
      list.Add(def.eventlist[i]);

   def.eventlist = new CEvent[def.eventlist.Length + 1];

   for (int i = 0; i < list.Count; ++i)
      def.eventlist[i] = (CEvent)list[i];
   def.eventlist[def.eventlist.Length] = de;
}

// Save our changes.
cgiengine.saveDefect(lSession, def);

[edit] Linking Objects

You can link defects, test cases, test runs, requirements and requirement documents within TestTrack.

[edit] Defect Link

CLink link = new CLink();
link.linkDefinitionName = "Related Items";
link.comment = "This is a new link!";

link.childList = new CLinkedItem[2];
link.childList[0] = new CLinkedItem();
link.childList[0].tablename = "Defect";
link.childList[0].entityID = 1; // CDefect.recordid (not DefNum)

link.childList[1] = new CLinkedItem();
link.childList[1].tablename = "Defect";
link.childList[1].entityID = 2; // CDefect.recordid (not DefNum)

long lResult = cgiengine.addLink(lSession, link);

[edit] Test Case Link

CLink link = new CLink();
link.linkDefinitionName = "Related Items";
link.comment = "This is a new link!";

link.childList = new CLinkedItem[2];
link.childList[0] = new CLinkedItem();
link.childList[0].tablename = "Defect";
link.childList[0].entityID = 5; // CDefect.recordid (not DefNum)

link.childList[1] = new CLinkedItem();
link.childList[1].tablename = "Test Case";
link.childList[1].entityID = 2; // CTestCase.recordid (not TCNum)

long lResult = cgiengine.addLink(lSession, link);

[edit] Test Run Link

CLink link = new CLink();
link.linkDefinitionName = "Parent/Child";
link.comment = "This is a new link!";

link.linkparent = new CLinkedItem();
link.linkparent.tablename = "Defect";
link.linkparent.entityID = 5; // CDefect.recordid (not DefNum)

link.childList = new CLinkedItem[1];
link.childList[0] = new CLinkedItem();
link.childList[0].tablename = "Test Run";
link.childList[0].entityID = 2; // CTestRun.recordid (not TRNum)

long lResult = cgiengine.addLink(lSession, link);

[edit] Requirement Link

CLink link = new CLink();
link.linkDefinitionName = "Parent/Child";
link.comment = "This is a new link!";

link.linkparent = new CLinkedItem();
link.linkparent.tablename = "Defect";
link.linkparent.entityID = 5; // CDefect.recordid (not DefNum)

link.childList = new CLinkedItem[1];
link.childList[0] = new CLinkedItem();
link.childList[0].tablename = "Requirement";
link.childList[0].entityID = 2; // CRequirement.recordid (not ReqNum)

long lResult = cgiengine.addLink(lSession, link);

[edit] Requirement Document Link

CLink link = new CLink();
link.linkDefinitionName = "Parent/Child";
link.comment = "This is a new link!";

link.linkparent = new CLinkedItem();
link.linkparent.tablename = "Defect";
link.linkparent.entityID = 5; // CDefect.recordid (not DefNum)

link.childList = new CLinkedItem[1];
link.childList[0] = new CLinkedItem();
link.childList[0].tablename = "Requirement Document";
link.childList[0].entityID = 2; // CRequirementDocument.recordid (not ReqDocNum)

long lResult = cgiengine.addLink(lSession, link);

[edit] Add File Attachment

// Lock the defect for edit.
CDefect def = cgiengine.editDefect(lSession, 1284, "", false);

// Create the file attachment.
string strFile = "C:\\readme.txt";

CFileAttachment file = new CFileAttachment();
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();

StreamReader reader = new StreamReader(strFile);
file.mstrFileName = Path.GetFileName(strFile);
file.mpFileData = enc.GetBytes(reader.ReadToEnd());
reader.Close();

// Add the attachment to the defect.
CReportedByRecord reprec = def.reportedbylist[0];
CFileAttachment[] afile = reprec.attachmentlist;
if (afile == null)
{
   def.reportedbylist[0].attachmentlist = new CFileAttachment[1];
   def.reportedbylist[0].attachmentlist[0] = file;
}
// should add else here, to handle defects with existing attachments.

// Save our changes.
cgiengine.saveDefect(lSession, def);

[edit] Promote User/Customer

At times you may need to turn a local user or customer into a global account. There are essentially two ways to do this. You can promote them as a new global user, or you can link them to an existing global user.


In the examples below, John Bark is a local user in our TestTrack project, Sarah Kaiser is a global user in the Seapine License Server.

// Promte as new global user
int iResult = cgiengine.promoteUser(lSession, "John Bark", null, "jbark");

// check that iResult == 0


// Promte to existing global user
int iResult = cgiengine.promoteUser(lSession, "John Bark", "Sarah Kaiser", null);

// check that iResult == 0

Note: The name parameters are searched based on your user settings in TT. So if you have names setup to display as 'lname, fname', then that's the format you should use when passing them to the call. If you passed them exactly as shown in the examples above (fname lname), they won't be found and the promote will fail.

[edit] Adding Drop-down Values

The basic process is very easy, you just create a value object and add it to the field.

CFieldValue[] aval = new CFieldValue[1];
aval[0] = new CFieldValue();
aval[0].value = "TEST1";
cgiengine.addDropdownFieldValuesForTable( lSession, "Test Run", "Type", aval);

For a complete listing of the tables and fields available, you can run this:

CDatabaseTable[] atable = cgiengine.getTableList(lSession);
for (int i = 0; i < atable.Length; ++i)
{
   try {
      CTableField[] afld = cgiengine.getDropdownFieldForTable( lSession, atable[i].name);
   } catch (Exception p_exception) { /* throws exception, if no fields exist on table */ }
}

[edit] Troubleshooting

With C# and Visual Studio, using the TestTrack SDK is pretty simple but it never hurts to have some tools to help with debugging.

  • MS SOAP Toolkit - This is a small Microsoft application that helps you trace SOAP requests. Start a formatted trace, point your SOAP client toward the tool's listening port, then have the tool redirect to the real web server port. With that configured, you can intercept the response/request loop and see exactly what is being communicated to the TestTrack Server.
  • soap UI - A free tool that lets you send raw SOAP envelopes. We sometimes use this internally to debug issues, since you can control the data being being sent. Going through C#, you're depending on their parser to translate objects into XML and pass those to the server.
