NHibernate Session Manager needs HttpContext for NUnit testing

C#, NHibernate, NUnit, unit testing, Web

In a codebase I work in, NHibernate needs an HttpContext to get its current session – like this:


public static ISession GetCurrentSession()
{
var context = HttpContext.Current;
var currentSession = context.Items[CurrentSessionKey] as ISession;
...

To get my hands on a session for a NUnit test – I put this in the setup:


HttpContext.Current = new HttpContext(
new HttpRequest(null, "http://tempuri.org", null),
new HttpResponse(null));

 

Also, I wipe the context in the teardown:

<code>

[TearDown]
public void TearDown()
{
HttpContext.Current = null;

}

</code>

Downloading a file from MVC controller to .ascx using javascript ajax

ajax, C#, javascript, MVC, Web, , , ,

Here is a simple way to download a file to a .net user control from a newer MVC controller.

The Controller code:

public FileResult DownloadSweetFile()
{
var downloadDirectory = _appSettings.PathToFile;
var filePathAndName = Path.Combine(downloadDirectory, "MySweetFile.pdf");

var cd = new System.Net.Mime.ContentDisposition
{
FileName = "MySweetFile.pdf",
Inline = false, //NOTE: This forces always prompting the user to download, not open file in the browser
};
Response.AppendHeader("Content-Disposition", cd.ToString());

return File(filePathAndName, "application/pdf");
}

I used a button on the page to fire the javascript

button type="button" id="btnSweetDownload" onclick="downloadSweetFile();" Click here to download a Sweet File!
(I removed the button tag so this will show correctly)

And here is the javascript to use in the .ascx file:

function downloadSweetFile() {
var url = '/MyControllerName/DownloadSweetFile';
window.location = url;
};
