Template Class OperatorTestHarness

• Defined in File test_harness.hpp

Base Types

• public holoscan::Application (Class Application)

• public std::enable_shared_from_this< OperatorTestHarness< OperatorType, Args... > >

template<typename OperatorType, typename ...Args>
class OperatorTestHarness : public holoscan::Application, public std::enable_shared_from_this<OperatorTestHarness<OperatorType, Args...>>

Test application wrapper for testing a Holoscan operator’s compute method.

This class provides a test harness for testing a Holoscan operator’s compute method. It supports an arbitrary number of input and output ports with arbitrary types. It also supports adding conditions to the operator under test.

Template Parameters

• OperatorType – The type of the operator to test

• Args – The types of the operator’s arguments

Public Functions

template<typename T>
inline std::shared_ptr<OperatorTestHarness> add_input_port(const std::string &name, const std::vector<T> &data)

inline virtual void compose() override

Compose a graph.

The graph is composed by adding operators and flows in this method.
