A dot ''.'' cause a problem to run the test

Hi,

In the ‘‘Applied Visual Design: Use the strong Tag to Make Text Bold’’ exercice.

When I’m trying to test.
I’ve found that if the ‘’.’’ dot is inside the solution to test … it wont work.
By removing it … it works!

In the video solution, the ‘’.’’ is there.

If you can just add the ‘’.’’ dot when trying to test.
This could help others.

Thank’s!

Can you share the code you are talking about?
