Could you please tell me how to write test class for restresource api

global class GetContactFromUKOrg{

  global static String insertContact()
    String jsonBody = RestContext.request.requestBody.toString().trim();
    System.debug('jsonBody'+jsonBody );
    List<Contact> ConObj = (List<Contact>)JSON.deserialize(jsonBody,List<Contact>.class);
       List<Contact> ConObjInsert = new List<Contact>();
       List<Contact> ConObjUpdate = new List<Contact>();
   Iterator<Contact> keys = ConObj.iterator();
                  Contact key = keys.next();
                 if(key.Id != null){
                 }else {
          if(ConObjUpdate != null){
              update ConObjUpdate;
          if(ConObjInsert != null){
              insert ConObjInsert;
              return JSON.serialize(ConObjInsert);
      }catch(Exception e){
         return JSON.serialize('Error while creating Contact');
     return 'Success';

You can write test class like below.

Note:- You may need make some changes. You can modify this test class as per your requirement.

private class GetContactFromUKOrgTest {

    static testMethod void myUnitTest() {
         RestRequest req = new RestRequest(); 
         RestResponse res = new RestResponse();

         req.addHeader('httpMethod', 'POST');
         req.requestUri = '/services/apexrest/sfdcCallingContact/';       
         String postData = 'Your actual request which covers both scenario in JSON format';
         String JsonMsg=JSON.serialize(postData);
         req.requestBody = Blob.valueof(JsonMsg);
         RestContext.request = req; 
         RestContext.response= res;


Also, refer below link for more info.

Let me know if this helps :)

Seems that your JSON file that you have inserted into Apex test clas in invalid.

Please make sure that you are using the same JSON as you are using at the time of testing the functionaloty.
