Hello Nishad,

Please check below sample code for write the test class for REST webservice.

Test Class: 
@isTest
private class MyAccountRestTest{
    static testMethod void testDelete() {

        Account objAcc = new Account();
        objAcc.Name = 'Test Account';
        insert objAcc;
        
        //do request
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();

        req.requestURI = '/services/apexrest/MyAccount12/' + objAcc.id;  
        req.httpMethod = 'GET';
        RestContext.request = req;
        RestContext.response = res;

        MyAccountRest.doDelete();
    }

    static testMethod void testGet() {
        
        Account objAcc = new Account();
        objAcc.Name = 'Test Account';
        insert objAcc;
        
        //do request
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();

        req.requestURI = '/services/apexrest/MyAccount12/' + objAcc.id;  
        req.httpMethod = 'GET';
        RestContext.request = req;
        RestContext.response = res;

        Account acc = MyAccountRest.doGet();
    }
    
    static testMethod void doPost() {
        
        //do POST request
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();
        
        req.requestURI = '/services/apexrest/MyAccount12/';
        req.httpMethod = 'POST';
        RestContext.request = req;
        RestContext.response = res;

        String results = MyAccountRest.doPost('Test Account', '123456', 'http://www.test.com');
    }
}

Hi,

Use this.
  
static testMethod void testInsertLead() {
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();
        insertUser();
        req.requestURI = '/servicerequest/apexrest/MyAccount12';  
        req.httpMethod = 'POST';
        RestContext.request = req;
        RestContext.response = res;
//Use starTest, stoptest to make callout.
        Test.startTest();
            ClassName.doPost('20011100','xyz','11111','Insert','True');
        Test.StopTest();
    }

Use test.StartTest() and Test.StopTest() to make callout.
