ossim-batch-test

ossim-batch test is a command line test application that can execute programs, test the results against expected results, and log the output with differences between expected results and run times. So you can easily test for changes in output and changes in output times.

Example of ossim-orthoigen test on a NITF image with RPC model:

For this test three things.
1) The height about the center of the test image. Because this image has a RPC sensor model which is affected by elevation, the first test is the height at the center of the image. If this changes the output bounds will also change.
2) The initial output of ossim-info -d -i -p of the source test image. This alone will test many changes in the code.
3) The orthoigen output. Test reprojecting image to an output file. Testing the histogram checks for pixel changes. Testing the ossim-info -d -i -p <output-image> tests for geometry changes.
