But that's also the case when using the -I option, or any option which allow to restrict the set of tests. The ITK tests for example don't seem to have a dependency on other tests. And the itkTestDriver program can now be used to easily run a test program and test the output images in a single ADD_TEST() command, so there is no dependencies on other tests like with ImageCompare. That's surely not possible for all the projects, but being able to run the tests in parallel as an option (-j ?) would definitively be a nice feature. > > -Mathieu > > On 7/24/07, Dr. Alex.
