Hi Anusha,

Please try the below code:
  
@isTest
public class Integration_ExampleTest {
    public testmethod static void dogetTest(){
        Account acc = new Account(Name = 'Test Account');
        insert acc;
        
        Test.startTest();
        RestResponse res = new RestResponse();
        RestRequest req = new RestRequest();
        req.params.put('Id', acc.Id);
        req.httpMethod = 'Get';
        req.addHeader('Content-Type', 'application/json'); 
        req.requestURI = '/services/apexrest/v1/Accountmanager/' ;  
        RestContext.request = req;
        RestContext.response = res;
        Account a = Integration_Example.doget();
        Test.stopTest();
    }
    
    public testmethod static void doDeleteTest(){
        Account acc = new Account(Name = 'Test Account',AccountNumber = '1234', Phone = '1234567890', Website = 'Test@test.com');
        insert acc;
        
        Test.startTest();
        RestResponse res = new RestResponse();
        RestRequest req = new RestRequest();
        req.params.put('Id', acc.Id);
        req.httpMethod = 'Get';
        req.addHeader('Content-Type', 'application/json');

        RestContext.request = req;
        RestContext.response = res;
        Account a = Integration_Example.doDelete();
        Test.stopTest();
    }
    
    public testmethod static void doPostTest(){
        RestResponse res = new RestResponse();
        RestRequest req = new RestRequest();
        req.httpMethod = 'Post';
        req.addHeader('Content-Type', 'application/json');
