Naming Conventions

Naming of variables should descriptive where needed. Loop Control Variables can use i if warranted. Most of these conventions are enforced through the clang-tidy and clang-format configuration files. See the file simplnx/docs/Code_Style_Guide.md for a more in depth explanation.

Filter Checklist

The help file simplnx/docs/Porting_Filters.md has documentation to help you port or write new filters. At the top is a nice checklist of items that should be noted when porting a filter.

Unit Testing

The idea of unit testing is to test the filter for proper execution and error handling. How many variations on a unit test each filter needs is entirely dependent on what the filter is doing. Generally, the variations can fall into a few categories:

• 1 Unit test to test output from the filter against known exemplar set of data
• 1 Unit test to test invalid input code paths that are specific to a filter. Don't test that a DataPath does not exist since that test is already performed as part of the SelectDataArrayAction.

Code Cleanup

• No commented out code (rare exceptions to this is allowed..)
• No API changes were made (or the changes have been approved)
• No major design changes were made (or the changes have been approved)
• Added test (or behavior not changed)
• Updated API documentation (or API not changed)
• Added license to new files (if any)
• Added example pipelines that use the filter
• Classes and methods are properly documented
