Description

AssertExample class contains methods for demonstrating current behavior. There are two base methods - printFirstNameWhenNotNull and printFirstNameWhenNotNullAndNotBlank, which have two simple assert statements.

For each method, there are accompanying methods with _likeGenerated and _likeGenerated_fixed suffixes. Methods with _likeGenerated suffix contain equivalent code as is generated for assert statements today. Methods with _likeGenerated_fixed suffix try to demonstrate a minimal change in generated code which would fix the problem of branch coverage for assert statements.
