/** This function tests the ExtractROI application. It verifies that, for different sets of parameters,
* the ROI computed by the application (startx, starty,sizex and sizey) is correct. The tested mode are :
* - Standard mode with invalid size (output is the full image)
* - Extent mode with invalid size (output is the full image)
* - Radius mode with invalid size (output is the full image)
* - Standard mode
* - Extent mode with pixel units
* - Extent mode with lonlat unit
* - Extent mode with phy unit
* - radius mode with pixel center and radius
* - radius mode with phy center and radius
* - radius mode with lonlat center and pixel radius
* - fit mode with image input
* For all these tests the application executed, but nothing is written to disk, and the output image is not updated.
* This means that the multiChannelExtractROI filter is not updated.
* Finally, in a last test, the channel option is set and the output is updated.
* Note that this test does not test the fit mode with vector data, which is tested in another test.
