Abstract: A data processing system defines a unit test for a dataflow graph comprising a plurality of executable components. The system receives an indication of a portion of a dataflow graph for testing. The system receives a parameter set indicating expected output data to be generated by execution of a component of the graph. The system receives input data for the component. The input data are indicated by the parameter set and configured to test a functionality of the component. The system defines a unit test of the component based on the parameter set. The unit test provides the input data to inputs of the dataflow graph, causes processing of the input data by the component of the dataflow graph to generate output data, and generates results data indicating a correspondence between the output data and the expected output data indicated by the parameter.

Abstract: A specification including a description of a first directed graph including a first plurality of components interconnected by a first set of one or more directed links is received. A graph interface is formed for the first plurality of components including: forming a first interface element of the graph interface, the first interface element being associated with a first port of a first component of the first number of components, and configuring one or more properties of the first interface element such that the first port of the first component is consistent with the one or more properties of the first interface element. A first implementation of the graph interface is formed including the first number of components, the forming including forming a first correspondence between the first interface element and the first port of the first component of the first number of components.

Abstract: In certain aspects, a method includes: receiving a first graph that includes components and flows, the components representing operations performed on data records, the flows representing flows of data records between components; receiving a specification that is separate from the first graph, the specification defining one or more insertions, each of the insertions associated with a flow of the first graph; generating one or more components that each corresponds to one of the insertions; and generating a second graph that includes components and flows that correspond to at least some of the components and flows of the first graph and the one or more generated components.

Abstract: Configurable testing of a computer program includes: storing a set of one or more testing specifications, and attribute information defining one or more attributes of a recognizable portion of the computer program; and processing, using at least one processor, the computer program according to at least a first testing specification associated with the computer program. The processing includes: traversing a representation of the computer program that includes elements that represent recognizable portions of the computer program, and while traversing the representation, recognizing recognizable portions of the computer program, and storing values of attributes, defined by the attribute information, of the recognized portions of the computer program.
