Failing to cover the code and pass the test

I am a beginner in unit testing. I am trying to write a test script, but I am stuck. I'd like to understand what I am doing wrong.
public ConvertExcelDocumentResponse ConvertExcelDocument(ConvertExcelDocumentRequest request)
{
var logger = Bootstrapper.Resolve<ILogger>();
ConvertExcelDocumentResponse response = new ConvertExcelDocumentResponse();
if (!string.IsNullOrEmpty(request.FileName) &&
System.IO.Path.GetExtension(request.FileName).ToLowerInvariant() == ".xls" &&
request.FileContent != null && request.FileContent.Length > 0)
{
response.FileContent = _httpClient.ConvertExcelDocument(request.FileContent, request.FileName);
response.FileName = System.IO.Path.GetFileNameWithoutExtension(request.FileName) + ".xlsx";
response.Success = true;
}
else
{
logger.LogError("Unable to convert Excel Document '" + request.FileName + "' only .xls files are allowed.");
response.FileContent = new byte[] { };
response.Success = false;
}
return response;
}
Here is my test:
/// <summary>
/// Test to Convert XLS to XLSX
/// </summary>
[TestCategory("DocumentService")]
[TestMethod]
public void Test_ConvertExcelDocumentResponse()
{
byte[] filecontent = new byte[] { };
string filename = "file";
using (ShimsContext.Create())
{
ConvertExcelDocumentRequest excelDocumentRequest1 = new ConvertExcelDocumentRequest()
{
FileName = "filename",
FileContent = new byte[] {},
};
ConvertExcelDocumentRequest excelDocumentRequest2 = new ConvertExcelDocumentRequest()
{
FileName = "",
FileContent = new byte[] {},
};
ShimDocumentService.AllInstances.ConvertExcelDocumentConvertExcelDocumentRequest = ((#this, Success) =>
{
return new ConvertExcelDocumentResponse()
{
FileContent=filecontent,
Success = true,
FileName = filename,
};
});
ShimHttpClientBase.AllInstances.ConvertWordDocumentByteArrayString = ((#this, fileContent, fileName) =>
{
return fileContent;
});
//Act
ILogger logger = Bootstrapper.Resolve<ILogger>();
var docService = new DocumentService();
//IDocumentService DocumentService = Bootstrapper.Resolve<IDocumentService>();
var excelResponse1 = docService.ConvertExcelDocument(excelDocumentRequest1);
var excelResponse2 = docService.ConvertExcelDocument(excelDocumentRequest2);
//Assert
Assert.AreEqual(excelResponse1.FileContent, filecontent );
Assert.AreEqual(excelResponse1.FileName, filename);
Assert.IsTrue(excelResponse1.Success, "Expects true");
Assert.AreEqual(excelResponse2.FileContent, filecontent);
Assert.AreEqual(excelResponse2.FileName, filename);
Assert.IsTrue(excelResponse2.Success, "Expects true");
}
}
This is passing the test but code coverage is 0%. I don't know where I am going wrong. I tried covering filename = null and few other conditions. not sure why it isn't covering my code

It looks like you'll need to also write a test where the filename is null or empty. That way you will cover the code in the else block.
Increasing code coverage often involves making your test exercise pieces of code that are not likely to be normally hit.

Parse WebCacheV01.dat in C#

I'm looking to parse the WebCacheV01.dat file using C# to find the last file location for upload in an Internet browser.
%LocalAppData%\Microsoft\Windows\WebCache\WebCacheV01.dat
I using the Managed Esent nuget package.
Esent.Isam
Esent.Interop
When I try and run the below code it fails at:
Api.JetGetDatabaseFileInfo(filePath, out pageSize, JET_DbInfo.PageSize);
Or if I use
Api.JetSetSystemParameter(instance, JET_SESID.Nil, JET_param.CircularLog, 1, null);
at
Api.JetAttachDatabase(sesid, filePath, AttachDatabaseGrbit.ReadOnly);
I get the following error:
An unhandled exception of type
'Microsoft.Isam.Esent.Interop.EsentFileAccessDeniedException' occurred

Additional information: Cannot access file, the file is locked or in use
string localAppDataPath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);

Is it not possible to read this without making modifications?

Utils
Task Scheduler Wrapper
You can use Microsoft.Win32.TaskScheduler.TaskService Wrapper to stop it using c#, just add this Nuget package [nuget]:https://taskscheduler.codeplex.com/
Usage
public static FileInfo CopyLockedFileRtl(DirectoryInfo directory, FileInfo fileInfo, string remoteEndPoint)
{
FileInfo copiedFileInfo = null;
using (var ts = new TaskService(string.Format(#"\\{0}", remoteEndPoint)))
{
var task = ts.GetTask(#"\Microsoft\Windows\Wininet\CacheTask");
task.Stop();
task.Enabled = false;
var byteArray = FileHelper.ReadOnlyAllBytes(fileInfo);
var filePath = Path.Combine(directory.FullName, "unlockedfile.dat");
File.WriteAllBytes(filePath, byteArray);
copiedFileInfo = new FileInfo(filePath);
task.Enabled = true;
task.Run();
task.Dispose();
}
return copiedFileInfo;
}

I was not able to get Adam's answer to work. What worked for me was making a copy with AlphaVSS (a .NET class library that has a managed API for the Volume Shadow Copy Service). The file was in "Dirty Shutdown" state, so I additionally wrote this to handle the exception it threw when I opened it:
catch (EsentErrorException ex)
{ // Usually after the database is copied, it's in Dirty Shutdown state
// This can be verified by running "esentutl.exe /Mh WebCacheV01.dat"
logger.Info(ex.Message);
switch (ex.Error)
{
case JET_err.SecondaryIndexCorrupted:
logger.Info("Secondary Index Corrupted detected, exiting...");
Api.JetTerm2(instance, TermGrbit.Complete);
return false;
case JET_err.DatabaseDirtyShutdown:
logger.Info("Dirty shutdown detected, attempting to recover...");
try
{
Api.JetTerm2(instance, TermGrbit.Complete);
Process.Start("esentutl.exe", "/p /o " + newPath);
Thread.Sleep(5000);
Api.JetInit(ref instance);
Api.JetBeginSession(instance, out sessionId, null, null);
Api.JetAttachDatabase(sessionId, newPath, AttachDatabaseGrbit.None);
}
catch (Exception e2)
{
logger.Info("Could not recover database " + newPath + ", will try opening it one last time. If that doesn't work, try using other esentutl commands", e2);
}
break;
}
}

I'm thinking about using the 'Recent Items' folder as when you select a file to upload an entry is written here:
C:\Users\USER\AppData\Roaming\Microsoft\Windows\Recent
string recent = (Environment.GetFolderPath(Environment.SpecialFolder.Recent));

Perforce Api - How to command "get revision [changelist number]"

I would like to implement the Perforce command "Get Revision [Changelist Number]" using the Perforce .NET API (C#). I currently have code that will "Get Latest Revision", but I need to modify it to get a specific changelist.
To sync the data with a changelist number, what should I do?
Source
// --------Connenct----------------
Perforce.P4.Server server = new Perforce.P4.Server(
new Perforce.P4.ServerAddress("127.0.0.1:9999"));
Perforce.P4.Repository rep = new Perforce.P4.Repository(server);
Perforce.P4.Connection con = rep.Connection;
con.UserName = m_P4ID;
string password = m_P4PASS;
Perforce.P4.Options opconnect = new Perforce.P4.Options();
opconnect.Add("-p", password);
con.Connect(opconnect);
if (con.Credential == null)
con.Login(password);
//----------Download----------
string clientPath = #"C:\P4V\";
string ws_client = clientPath;
Perforce.P4.Client client = new Perforce.P4.Client();
client.Name = ws_client;
client.Initialize(con);
con.CommandTimeout = new TimeSpan(0);
IList<Perforce.P4.FileSpec> fileList = client.SyncFiles(new Perforce.P4.Options());
//----------Disconnect------------
con.Disconnect();
con.Dispose();
Edit: Attempt 1
Perforce.P4.DepotPath depot = new Perforce.P4.DepotPath("//P4V//");
Perforce.P4.LocalPath local = new Perforce.P4.LocalPath(ws_client);
Perforce.P4.FileSpec fs = new Perforce.P4.FileSpec(depot, null, local,
Perforce.P4.VersionSpec.Head);
IList<Perforce.P4.FileSpec> listFiles = new List<Perforce.P4.FileSpec>();
listFiles.Add(fs);
IList<Perforce.P4.FileSpec> foundFiles = rep.GetDepotFiles(listFiles,
new Perforce.P4.Options(1234)); // 1234 = Changelist number
client.SyncFiles(foundFiles, null);
Error Message
Usage: files/print [-o localFile -q] files...Invalid option: -c.
I do not know the problem of any argument.
Or there will not be related to this reference source?
Edit 2
I tried to solve this problem. However, it does not solve the problem yet.
Perforce.P4.Changelist changelist = rep.GetChangelist(1234);
IList<Perforce.P4.FileMetaData> fileMeta = changelist.Files;
In this case, I could get only the files in the changelist. I would like to synchronize all files of the client at the moment of changelist 1234.

SyncFiles takes an optional FileSpec arg. You can specify a file path and a revision specifier with that FileSpec arg. Here are the relevant docs:
FileSpec object docs
SyncFiles method docs
You don't need to run GetDepotFiles() to get the FileSpec object; you can just create one directly as shown in the FileSpec object docs. The error you are getting with GetDepotFiles() is because it expects the change number to be specified as part of the FileSpec object passed into as the first argument to GetDepotFiles().
To expand further, GetDepotFiles() calls the 'p4 files' command when it talks to Perforce. new Perforce.P4.Options(1234) generates an option of '-c 1234' which 'p4 files' doesn't accept. That's why the error message is 'Usage: files/print [-o localFile -q] files...Invalid option: -c.'

I struggled with the same problem as well. Finally based on Matt's answer I got it working. Please see simple example below.
using (Connection con = rep.Connection)
{
//setting up client object with viewmap
Client client = new Client();
client.Name = "p4apinet_solution_builder_sample_application_client";
client.OwnerName = "p4username";
client.Root = "c:\\clientRootPath";
client.Options = ClientOption.AllWrite;
client.LineEnd = LineEnd.Local;
client.SubmitOptions = new ClientSubmitOptions(false, SubmitType.RevertUnchanged);
client.ViewMap = new ViewMap();
client.ViewMap.Add("//depotpath/to/your/file.txt", "//" + client.Name + "/clientpath/to/your/file.txt", MapType.Include);
//connecting to p4 and creating client on p4 server
Options options = new Options();
options["Password"] = "p4password";
con.UserName = "p4username";
con.Client = new Client();
con.Connect(options);
con.Client = rep.CreateClient(client);
//syncing all files (in this case 1) defined in client's viewmap to the changelist level of 12345
Options syncFlags = new Options(SyncFilesCmdFlags.Force, 100);
VersionSpec changeListLevel = new ChangelistIdVersion(12345);
List<FileSpec> filesToBeSynced = con.Client.ViewMap.Select<MapEntry, FileSpec>(me => new FileSpec(me.Left, changeListLevel)).ToList();
IList<FileSpec> results = con.Client.SyncFiles(filesToBeSynced, syncFlags);
}

The following code should allow you to sync a depot to a particular revision (changelist number).
string uri = "...";
string user = "...";
string workspace = "...";
string pass = "...";
int id = 12345; // the actual changelist number
string depotPath = "//depot/foo/main/...";
int maxItemsToSync = 10000;
Server server = new Server(new ServerAddress(uri));
Repository rep = new Repository(server);
server = new Server(new ServerAddress(uri));
rep = new Repository(server);
Connection con = rep.Connection;
con.UserName = user;
con.Client = new Client();
con.Client.Name = workspace;
// connect
bool connected = con.Connect(null);
if (connected)
{
try
{
// attempt a login
Perforce.P4.Credential cred = con.Login(pass);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
con.Disconnect();
connected = false;
}
if (connected)
{
// get p4 info and show successful connection
ServerMetaData info = rep.GetServerMetaData(null);
Console.WriteLine("CONNECTED TO " + info.Address.Uri);
Console.WriteLine("");
try
{
Options opts = new Options();
// uncomment below lines to only get a preview of the sync w/o updating the workspace
//SyncFilesCmdOptions syncOpts = new SyncFilesCmdOptions(SyncFilesCmdFlags.Preview, maxItemsToSync);
SyncFilesCmdOptions syncOpts = new SyncFilesCmdOptions(SyncFilesCmdFlags.None, maxItemsToSync);
VersionSpec version = new ChangelistIdVersion(id);
PathSpec path = new DepotPath(depotPath);
FileSpec depotFile = new FileSpec(path, version);
IList<FileSpec> syncedFiles = rep.Connection.Client.SyncFiles(syncOpts, depotFile);
//foreach (var file in syncedFiles)
//{
// Console.WriteLine(file.ToString());
//}
Console.WriteLine($"{syncedFiles.Count} files got synced!");
}
catch (Exception ex)
{
Console.WriteLine("");
Console.WriteLine(ex.Message);
Console.WriteLine("");
}
finally
{
con.Disconnect();
}
}
}

Trying to download file from FileCabinet in NetSuite using C# program

I need to download JPG file from FileCabinet in NetSuite. For that I know the file name, so I searched file and assigned to FileObject. I got the object right, but got NULL content. I am providing here some code. Can anybody point out the error or any missing step here? Thank you.
var result = _service.search(flSearch);
if (result.totalRecords > 0)
{
recordList = result.recordList;
Record[] records = new Record[recordList.Length];
for (int j = 0; j < recordList.Length; j++)
{
if (recordList[j] is File)
{
File itemImage = (File)(recordList[j]);
byte[] data;
data = new Byte[(int)itemImage.fileSize];
data = itemImage.content; //Here getting NULL value
FileStream inFile;
using (inFile = new FileStream("newImage.jpg", FileMode.Create, FileAccess.Write))
{
inFile.Write(data, 0, data.Length);
}
}
}
}

itemImage is just a string - base64.
take that string and do a base64 decode and save that to your local file.

If the search is based on the internal id of the file you want to search, then the following code may help
var service = LoginNetSuite();
Tuple<string, string> fileContent = null;
FileSearch fileSearch = new FileSearch();
FileSearchBasic fileSearchBasic = new FileSearchBasic();
// Specify the folder in which the search is to be done.
SearchMultiSelectField folderFilter = new SearchMultiSelectField();
folderFilter.#operator = SearchMultiSelectFieldOperator.anyOf;
folderFilter.operatorSpecified = true;
RecordRef[] folder = new RecordRef[1];
folder[0] = new RecordRef();
folder[0].internalId = "78990"; // 78990 => Internal id of the folder.
folderFilter.searchValue = folder;
fileSearchBasic.folder = folderFilter;
// Specify the file internal id.
SearchMultiSelectField fileFilter = new SearchMultiSelectField();
fileFilter.#operator = SearchMultiSelectFieldOperator.anyOf;
fileFilter.operatorSpecified = true;
RecordRef[] rec = new RecordRef[1];
rec[0] = new RecordRef();
rec[0].internalId = "345656"; // 345656 => Internal id of the file.
fileFilter.searchValue = rec;
fileSearchBasic.internalId = fileFilter;
fileSearch.basic = fileSearchBasic;
var result = service.search(fileSearch);
var recordList = (Record[])result.recordList;
if (recordList != null && recordList.Length != 0)
{
var file = (File)result.recordList.First();
fileContent = new Tuple<string, string>(file.url, file.name);
}
In this code the folder internal id and the file internal id is given as the search parameters. So the file search will be done in the specified file cabinet with specified file id.
The response from netsuite will consist of the internal id, file name, url, folder name etc. The file can be downloaded from the url location.

Thanks for your help.

The error message is correct, you cannot create an instance of that class, it is declared abstract.
http://msdn.microsoft.com/en-us/library/system.servicemodel.channels.messageheader.aspx
See if the static method MessageHeader.CreateHeader will work for you. Note there is several overloads, so pick the best one for you.
