Usage
This is a VTK regression testing framework. Looks like this:
vtkTesting* t = vtkTesting::New();
Two options for setting arguments
Option 1: for ( cc = 1; cc < argc; cc ++ ) { t->AddArgument
(argv[cc]); }
Option 2: t->AddArgument("-D"); t->AddArgument(my_data_dir);
t->AddArgument("-V"); t->AddArgument(my_valid_image);
...
Two options of doing testing:
Option 1: t->SetRenderWindow(renWin); int res = t-
>RegressionTest(threshold);
Option 2: int res = t->RegressionTest(test_image,
threshold);
...
if ( res == vtkTesting::PASSED ) { Test passed } else { Test
failed }
To create an instance of class vtkTesting, simply invoke its
constructor as follows
obj = vtkTesting
Methods
The class vtkTesting has several methods that can be used.
They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkTesting class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkTesting = obj.NewInstance ()
* vtkTesting = obj.SafeDownCast (vtkObject o)
* obj.SetFrontBuffer (int ) - Use front buffer for tests. By
default use back buffer.
* int = obj.GetFrontBufferMinValue () - Use front buffer for
tests. By default use back buffer.
* int = obj.GetFrontBufferMaxValue () - Use front buffer for
tests. By default use back buffer.
* obj.FrontBufferOn () - Use front buffer for tests. By
default use back buffer.
* obj.FrontBufferOff () - Use front buffer for tests. By
default use back buffer.
* int = obj.GetFrontBuffer () - Use front buffer for tests.
By default use back buffer.
* int = obj.RegressionTest (double thresh) - Perform the
test and return result. At the same time the output will
be written cout
* int = obj.RegressionTest (vtkImageData image, double
thresh) - Compare the image with the valid image.
* int = obj.CompareAverageOfL2Norm (vtkDataSet pdA,
vtkDataSet pdB, double tol) - Compute the average L2 norm
between all point data data arrays of types float and
double present in the data sets "dsA" and "dsB" (this
includes instances of vtkPoints) Compare the result of
each L2 comutation to "tol".
* int = obj.CompareAverageOfL2Norm (vtkDataArray daA,
vtkDataArray daB, double tol) - Compute the average L2
norm between two data arrays "daA" and "daB" and compare
against "tol".
* obj.SetRenderWindow (vtkRenderWindow rw) - Set and get the
render window that will be used for regression testing.
* vtkRenderWindow = obj.GetRenderWindow () - Set and get the
render window that will be used for regression testing.
* obj.SetValidImageFileName (string ) - Set/Get the name of
the valid image file
* string = obj.GetValidImageFileName () - Set/Get the name
of the valid image file
* double = obj.GetImageDifference () - Get the image
difference.
* obj.AddArgument (string argv) - Pass the command line
arguments into this class to be processed. Many of the Get
methods such as GetValidImage and GetBaselineRoot rely on
the arguments to be passed in prior to retrieving these
values. Just call AddArgument for each argument that was
passed into the command line
* obj.CleanArguments ()
* string = obj.GetDataRoot () - Get some paramters from the
command line arguments, env, or defaults
* obj.SetDataRoot (string ) - Get some paramters from the
command line arguments, env, or defaults
* string = obj.GetTempDirectory () - Get some paramters from
the command line arguments, env, or defaults
* obj.SetTempDirectory (string ) - Get some paramters from
the command line arguments, env, or defaults
* int = obj.IsValidImageSpecified () - Is a valid image
specified on the command line areguments?
* int = obj.IsInteractiveModeSpecified () - Is the
interactive mode specified?
* int = obj.IsFlagSpecified (string flag) - Is some
arbitrary user flag ("-X", "-Z" etc) specified
* obj.SetBorderOffset (int ) - Number of pixels added as
borders to avoid problems with window decorations added by
some window managers.
* int = obj.GetBorderOffset () - Number of pixels added as
borders to avoid problems with window decorations added by
some window managers.
* obj.SetVerbose (int ) - Get/Set verbosity level. A level
of 0 is quiet.
* int = obj.GetVerbose () - Get/Set verbosity level. A level
of 0 is quiet.
