1. Install barryvdh/laravel-dompdf Package In Your Application
composer require barryvdh/laravel-dompdf
2. Add Service Provider And Aliase, After package installation, we will add service provider and aliase in config/app.php.
'providers' => [
	
	Barryvdh\DomPDF\ServiceProvider::class,
],

'aliases' => [
	
	'PDF' => Barryvdh\DomPDF\Facade::class,
],
 3. Now create a new controller and writhe the following command in header of that controller
 use PDF;
Now make a function to generate pdf and enter the following code

 $customer = Part::find($id);
         $pdf = PDF::loadView('customers.partPDF', compact('customer'))->setPaper('a4');
         return $pdf->stream('customerPDF.pdf');
4. Now make a blade file and then wite the following smaple code 


<style>
     td, th {
        border: 1px solid gray;
        padding: 8px;
    }
    table{

reate a new branch named Homework17 using GitHub Desktop.

2. Create a new file, Homework17.java in IntelliJ IDEA.

3. Create a test case, addSongToPlaylist() using @Test annotation
and the helper/reusable methods we created.

4. Navigate to "https://bbb.testpro.io/".

5. Log in with your credentials.

6. Search for a song (choose any song of your choice).

7. Click View All to display the search results.

8. Click the first song in the search results.

9. Click ADD TO...

10. Choose the playlist to add it to, (we can create a new one with a unique name).

11. Verify that the notification message appears.

12. Verify that notification message has the text, "Added 1 song into {your playlist}".

13. Commit your changes to the new branch Homework17.

14. Push your code to the remote repository.

15. Create a pull request.


Note: Your work will be auto graded so you can continue with the next assignment in less than a minute (just refresh the results page).
