Write Positive Test Unit has still problem

Hello everyone,

the issues into the challenge control still persists.

As a Premise, I have tried different suggestions with 2 different trail-head org, a previously used and a fresh new one, the language is set to English and I have checked the spelling and coverage.

In my opinion is the challenge check that's not working properly due to the fact It's asking to call a test method isHighPriority with the same name of the AccountWrapper method, which we have to test.

Following the examples:

AccountWrapper piece of code

---------------------------------------------------------------

  public Boolean isHighPriority() {

    if (getRoundedAvgPriceOfOpps() > 100000.00) {

      return true;

    }

    return false;

  }

---------------------------------------------------------------

If I use into the test class a name like this:

  @isTest static void testIsHighPriorityFalse() {

   //TEST CODE

    Test.startTest();

    for(AccountWrapper a : accounts){

      System.assertEquals(a.isHighPriority(), false, 'Priority expected to be high');

      System.debug('get rounded price of opps for accounts b:'+ a.getRoundedAvgPriceOfOpps());

      }

    Test.stopTest();

    }

I get this error:

We can't find the method “isHighPriority()” in the “AccountWrapperTests” class.

If I use into the test class a name like this:

  @isTest static void IsHighPriority() {

   //TEST CODE

    Test.startTest();

    for(AccountWrapper a : accounts){

      System.assertEquals(a.isHighPriority(), false, 'Priority expected to be high');

      System.debug('get rounded price of opps for accounts b:'+ a.getRoundedAvgPriceOfOpps());

      }

    Test.stopTest();

    }

I get this error:

We can't find the expected declarations for the test method “isHighPriority” in the AccountWrapperTests class.

Is there someone that can help providing suggestions o fixing the issue?

Thanks 

Attached the coverage I got, the class and test class I have tried with this chellange.

The coverage is around 93%
