SharePoint API Test Series-OM methods operations on recorded item (the magical work of delegates)

To test the recorded item dynamic call OM methods, the interface is as follows:

Enter the site's url,file relative URL in SharePoint, select the OM action type, and click Test for testing. The code is as follows:

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Windows.Forms;usingMicrosoft.SharePoint;namespacerecordsomtest{ Public Partial classForm1:form { PublicForm1 () {InitializeComponent (); OMMETHODS_COMBOBOX.ITEMS.ADD ("Rename"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Item Delete"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Delete"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Item Recycle"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Recycle"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Undo Check out"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Check in"); OMMETHODS_COMBOBOX.ITEMS.ADD ("File Check out"); }         Public Delegate voidCallommethod (SPFile file); Private voidTest_button_click (Objectsender, EventArgs e) {            /*Block Delete Test. */            //Rename test.Callommethod Rename = file + {file. item["Name"] ="Kkk.txt"; file. Item.update ();            }; //Delete Test 1.Callommethod delete1 = File = ={file. Item.delete ();            }; //Delete Test 2.Callommethod Delete2 = File = ={file. Delete ();            }; //Delete Test 3.Callommethod Delete3 = File = ={file. Item.recycle ();            }; //Delete Test 4.Callommethod delete4 = File = ={file. Recycle ();            }; /*Block Edit and delete test. */            //undocheckout test.Callommethod undockout = File = ={file. UndoCheckout ();            }; //CheckIn test.Callommethod Ckin = file + {file. CheckIn ("Check in.");            }; //CheckOut test.Callommethod ckout = File = ={file. CheckOut ();            }; Switch(ommethods_combobox.text) { Case "Rename":                    //Rename test.doomtest (Rename);  Break;  Case "File Item Delete": Doomtest (delete1);  Break;  Case "File Delete": Doomtest (DELETE2);  Break;  Case "File Item Recycle": Doomtest (Delete3);  Break;  Case "File Recycle": Doomtest (DELETE4);  Break;  Case "File Undo Check out": Doomtest (undockout);  Break;  Case "File Check in": Doomtest (Ckin);  Break;  Case "File Check out": Doomtest (ckout);  Break; }        }        Private voiddoomtest (callommethod cm) {using(SPSite site =NewSPSite (Siteurl_textbox.text)) {SPWeb Web=site.                RootWeb; SPFile file=web.                GetFile (Filepath_textbox.text); Try{ cm.                    Invoke (file); //Reach This step means test failed.Result_richtextbox.text ="Test failed.\r\n"; Result_richtextbox.selectioncolor=color.red; }                Catch(Exception ex) {Result_richtextbox.text="Test passed.\r\n"; Result_richtextbox.select (0, result_richTextBox.Text.Length); Result_richtextbox.selectioncolor=Color.green; Result_richtextbox.text+=string.                Concat (ex); }             }        }    }}

Extract the public part of each OM methods unit test as a doomtest (Callommethod cm) method, in lieu of calling a delegate method ( Orange font ) for different parts of each test. Then we declare the type of the delegate method (the delegate method needs to pass in a parameter of type SPFile):

 Public Delegate void Callommethod (SPFile file);

Then instantiate the delegate according to the different parts of each test:

//Rename test.Callommethod Rename = file + {file. item["Name"] ="Kkk.txt"; file. Item.update (); };//Delete Test 1.Callommethod delete1 = File = ={file. Item.delete (); };//Delete Test 2.Callommethod Delete2 = File = ={file. Delete (); };//Delete Test 3.Callommethod Delete3 = File = ={file. Item.recycle (); };//Delete Test 4.Callommethod delete4 = File = ={file. Recycle (); };//undocheckout test.Callommethod undockout = File = ={file. UndoCheckout (); };//CheckIn test.Callommethod Ckin = file + {file. CheckIn ("Check in."); };//CheckOut test.Callommethod ckout = file + {file. CheckOut (); };

This is the magic of commissioning in testing, greatly reducing the amount of repetitive code.
