Hello , 

I need a help on Advanced Apex Specialist Step 8 , I have created the test classes and all of them successfully executed , overall coverage is 86 however I am facing this issue.

Challenge Not yet complete... here's what's wrong: 
Ensure that after you clear test data, you run your tests once and the required test coverage is achieved.

can anyone help 

Thanks

Getting the below error message on the "Advanced Apex Specialist" on the last step. Had made sure all test classes are covered and OrderExtension works as expected and there are more than 12 products created. I tried to delete the existing data on the system and recreated it, Very likely that causes the below error message. Have anyone got the similar error message? Would appreciate any suggestions to solve it.

Challenge Not yet complete... here's what's wrong: 
Ensure that you have at least 12 products created and that OrderExtension is still working as specified in the earlier challenge.
 

Hello,
While solving challenge 8 I am getting an error:- 
Challenge Not yet complete... here's what's wrong: 
Ensure that orderTrigger and orderHelper are still working as specified in the earlier challenge.
Please let me know what I am doing wrong else paste the correct code here.
My code goes as follows-:
