Mockito.thenReturn (...) does not work

Question

Testing class

public class CollectionImplementationUnitTest {

  CollectionImplementation colImp;

  public void setup() throws Exception {
    ...
    colImp = Mockito.spy(new CollectionImplementation());
    ...
  }

  private String mockHistoryFromStrgyTable() {
    String value1 = "myValue";
    return value1;
  }

  @Test 
  public void testgetinfo (){
    ...
    Mockito.when(
      colImp.historyFromStrgyTable(
         Mockito.anyString(),Mockito.anyString(),Mockito.anyString()
      )
    )
    .thenReturn(mockHistoryFromStrgyTable());

    CollectionsAccount Info = colImp.accountInfo(
      "string1","string2","string3", new IdentityAcc(), TableLst
    );

    //sometestmethods and asserts
  }
}

Class under the test

public class CollectionImplementation {
  ...
  @Override
  public CollectionsAccount accountInfo(("string1","string2","string3", new IdentityAcc(), TableLst)) {
      DetailsHelper helper = new (db2, "string",getmethod());
      return helper.accountInfo("string1","string2", new IdentityAcc(), TableLst); 
  }

  public String historyFromStrgyTable(){
    //contains a call to the data base
  }
}

DetailsHelper

public class DetailsHelper{
  public CollectionsAccount accountInfo((String string1,String string2,String string3, new IdentityAcc(), TableLst)){
  ...
  String paymentdetails = historyFromStrgyTable();  
  }
   public String historyFromStrgyTable(){
   //contains a call to the data base
   }
}

When I try to make fun of the data for the HistoryFromStrgyTable () method, it actually accesses HistoryFromStrgyTable () instead of getting from mockHistoryFromStrgyTable ().

My test cases do not work on this line

Mockito.when(col_Imp.HistoryFromStrgyTable(Mockito.anyString(),
  Mockito.anyString(),Mockito.anyString())).thenReturn(  mockHistoryFromStrgyTable());

Can anyone help me with this. I don’t understand what happened. I also changed the mockHistoryFromStrgyTable () method from private to public, since mockito cannot mock private methods.

Mockito.doReturn(mockHistoryFromStrgyTable()).when(colImp).
    historyFromStrgyTable(Mockito.anyString(),Mockito.anyString(),Mockito.anyString());
