Test Class for @HTTP Post

Hi Everyone,
         I have written a @HTTP Post method which works fine. I need a sample code to write it's test class . Can anyone  please help me with this? My test method is giving an error saying that method doPost() does not exist (second last line).

Apex Code:

@RestResource(urlMapping='/v1/cans/*')
global with sharing class MyRestResource {
  @HttpPost
    global static DocWrapper doPost(String Description, String ParentId, String FilePathname, String Name, String Type) {
        DocWrapper response=new DocWrapper();
        Document__c doc= new Document__c();
        doc.Doc_Name__c=Name;
        doc.Type__c=Type;
        doc.CAN__c=ParentId;
        doc.Link__c=FilePathname;
        doc.Description__c=Description;
        insert doc;
        response.message='Doc Inserted';
        return response;
        
     }
       global class DocWrapper {          
          public String message;
     }
}

Test Method:


static testMethod void testDoPost(){
        
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();
        
        RecordType RecType = [Select Id From RecordType  Where SobjectType = 'CAN__c' and Name = 'CAN Fed'];    
        CAN__c cf = new CAN__c (Name='Test CAN 1',RecordTypeId=RecType.Id);
        insert cf;
        String CanId=cf.id;
        
        req.requestURI = '/services/apexrest/v1/cans/';  
        req.addParameter('Description', '0000000');
        req.addParameter('ParentId',CanId);
        req.addParameter('FilePathname', 'www.google.com');
        req.addParameter('Name', '1wer2547');
        req.addParameter('Type', '1wer2547');

        req.httpMethod = 'POST';
        RestContext.request = req;
        RestContext.response = res;
        
        Test.startTest();
        MyRestResource.DocWrapper results = MyRestResource.doPost();
        Test.stopTest();
        

    }

Hi,
the problem is that your doPost method is expecting some parameters (String Description, String ParentId, String FilePathname, String Name, String Type).

Try something like this:
Test.startTest();
MyRestResource.DocWrapper results = MyRestResource.doPost('000000', CanId, 'www.google.com', '1wer2547', '1wer2547');
Test.stopTest();
