YouTube playlist exporter

 

The point here is about how simple is in our days to make a simple script as a programmer.

I wanted to export my playlists ( 5 minutes .NET , Export Word Exce l PDF  , EF 6 , Traceability ) videos into a simple HTML file that I could put into my website.

I searched first on internet – however, I found just you tube google api .

So I read the documentation (e.g. https://developers.google.com/youtube/v3/docs/videos/list)  , grab a developer key from https://console.developers.google.com/ and made a simple project.

Used also a NuGet package for JSON( Newtonsoft.Json) and one for export in Excel /Word /HTML / PDF /ODS (ExporterWordExcelPDF).

Total time : 2 hours. You can find the project here https://github.com/ignatandrei/YouTube . It has only console application  – but it will have soon a GUI .

The point is that in our days it is easy to use third party application – and , for a programmer, easy as pie( eating, not making ; – ) )

Let’s suppose that we have a program that have Departments and Employees.

And we want to make sure that, when we add an employee, the department must exists.

We can ensure this from database ( by foreign key) but we can pro-actively search for the department and throw a more meaningful validation .

More, I like more validation than errors.

So, let’s suppose that in the Validation for the Employee we must check in the database for the IdDepartment to see if there is such a department.

How could we make a test for that runs without a database ?

With some trick:  we first Record with a database  – then we can Play the file – and we do not need anymore the database. The test is self contained. 

 

Let’s see in action here

 

Database.SetInitializer<ContextForDatabase>(null);
            #region set record EF
            var record = new InterceptionRecordOrPlay(@"VerifyIValidatableWorks.zip", ModeInterception.Play);

            DbInterception.Add(record);
            #endregion
            var e= new Employee();
            e.ValidateEmployee = true;
            e.IDDepartment = 60000;
            var err= e.Validate(null).ToArray();
            Assert.IsNotNull(err);
            Assert.AreEqual(1, err.Length);

Entity Framework Record And Play

With this helper you can record and then play the actions in Entity Framework(>= 6).

For recording actions just reference the dll and use

DbInterception.Add(new InterceptionRecordOrPlay(@"a.zip", ModeInterception.Record)); 

(Note: For ASP.NET you will use Server.MapPath("~/a folder that supports write/namefile.zip")

For replay use

DbInterception.Add(new InterceptionRecordOrPlay(@"a.zip", ModeInterception.Play));

This can be use for

  1. Unit Testing
  2. Making demos
  3. Recording user actions when a bug occurred

 

Source code is available at  https://github.com/ignatandrei/EFRecordAndPlay/wiki/

and has also a test 😉

There is also a NuGet package at https://www.nuget.org/packages/EFRecordAndPlay/
