#Trailhead Challenges2.427 diskutieren mit

Hi  Trailblazers ,

Unable to complete the challenge for Write Positive Tests - Advanced Apex Testing , I have checked the code for the required naming of the test method as well as the syntax.

I am not understanding what is causing the below error , while checking the challenge.

Any pointers towards where I am making an error , will be greatly appreciated.

Thanks in advance
