To better follow conventional pytest style, this removes the outer wrapper class in favor of a function for some tests. These tests were picked as they are relatively simple and presented no barriers to a quick port. The assert* methods are replaced with assert statements. When necessary, a fixture is used to create a temporary directory. This commit does not convert the entire test suite to this style as some test classes use methods or other advanced features that are difficult to automatically convert. The goal is to address these issues in followup commits. Refs #4193
