NodeDevel_test Class Reference

Description

Test:

verify support for developing Render Node functionality.

• raw processing functions to generate and manipulate TestFrame data, including hash chaining.
• a »TestRand-Ontology«, which is a test helper framework, and mimics a real Domain Ontology (as would be accessible through the adapter plug-in of a specific media handling library.
• some convenience shortcuts to build test-nodes

Test:

multichannel data hash-chain manipulation

• use multichannel pseudo random input data
• store away a clone copy before manipulation
• the #manipulateMultichan() operates in-place in the buffers
• each buffer has been marked with a new checksum afterwards
• and each buffer now differs from original state
• verify that corresponding data points over all channels have been linked by a hashcode-chain, seeded with the param and then consecutively hashing in data from each channel.

Test:

function to apply a numeric computation to test data frames;

Remarks

here basically the same hash-chaining is used as for #manipulateMultichan, but only one hash-chain per data point is used and output is written to a different buffer.

testRand_buildFilterNode()

void testRand_buildFilterNode ( )

inlineprivate

Test:

use the »TestRand«-framework to setup a filter node

• implementation is backed by the ont::manipulateFrame() function
• it thus operates on TestFrame data and results can be verified
• the generated spec-recod provides a processing-functor binding and node-spec
• can build and wire a Node processing chain with a source node and a »filter« node based on this data manipulation, which exactly reproduces the data content generated by the stand-alone invocation.

Remarks

such a test-setup thus not only allows to prove that the function was invoked, but also the order in which the processing took place, due to hash-chaining applied to every single data word in the TestFrame buffer.

Test:

use the »TestRand«-framework to setup a two-chain mixer node

• demonstrate convenience setup to package the ont::combineFrames() as »mix« Node
• this time, we need two source chains, both generating TestFrame data
• complete processing with all steps can be verified by performing similar computations directly and comparing the result checksum.
