Objective

There is NA-MIC funded infrastructure in place to regression test the command line programs found in Applications/CLI. Surprisingly, of the over 50 command line programs in the current Slicer3 distribution, only 11 have tests. This project will illustrate the importance of testing and show how easy it is to create tests for command line programs using the existing infrastructure. The project will document the process, create tests and help others to create tests.

Approach, Plan

Using the existing infrastructure, the project will create regression tests for many of the existing command line programs in Applications/CLI. The project will provide expert assistance to those who feel that creating a test is difficult. A Wiki page will provide step-by-step procedures to test the command line programs.

Progress

There is really no excuse for the lack of testing in Applications/CLI. The infrastructure that has been in place for a few years makes it almost painless to test command line programs. Better documentation and peer pressure will help improve the situation.

Tests have been created for all of the command line programs in Applications/CLI (not including sub directories). Three types of tests exist:

1. --help tests just run the command line program with the --help flag. These tests are as basic as a test can be. All they really test is whether or not the command line program and build, link and report help.
2. Smoke tests run the program put do not check the results of the program. These are one step above the --help tests and should be the minimum test for each program.
3. Regression tests run the program and compare the resulting output with a baseline output. Currently only image regression testing is available. Each command line program that produces an image should have a regression test.

Documentation: TODO

Status

The table shows each command line program and its testing status. Under Test Type, the item in parentheses is a test that has been added as part of this project.
