System and method for generating test data and testcases to test an application programming interface

A method for generating test data and test cases to examine an application programming interface comprising:

• identifying, by a trace collection module of a processing subsystem to be executed by a processor of a computer-implemented system, one or more variable names and corresponding one or more variable types to generate a schema of the application programming interface;
• recognizing, and generating, by a schema inference module of the processing subsystem, the schema of the application programming interface and application programming interface data related to the application programming interface, wherein the schema comprises the one or more variable names and the corresponding one or more variable types;
• generating, by a semantic profile generation module of the processing subsystem, a predefined set of semantic profiles;
• enabling, by the semantic profile generation module of the processing subsystem, a user to define a custom semantic profile by a plugin mechanism;
• deducing, by the semantic profile generation module of the processing subsystem, the custom semantic profile for a plurality of parameters using a plurality of heuristics and pattern matching based on a plurality of patterns;
• applying, by the semantic profile generation module of the processing subsystem, restriction on a value pertaining to at least one variable type of the one or more variable types corresponding to at least one variable name of the one or more variable names;
• dividing, by the semantic profile generation module of the processing subsystem, the at least one variable name into a plurality of individual components based on a plurality of boundaries to filter out a plurality of words ineffective to the custom semantic profile;
• expanding, by the semantic profile generation module of the processing subsystem, a plurality of abbreviated components among the plurality of individual components into complete words based on the plurality of heuristics and the plurality of patterns of the complete words to match the plurality of individual components with one of a plurality of predefined semantic profile names associated with the predefined set of semantic profiles;
• generating, by a test case generation module of the processing subsystem, a plurality of test cases using test data generated based on at least one of the predefined set of semantic profiles and the custom semantic profile, wherein the plurality of test cases is a set of input data for testing the application programming interface;
• organizing and grouping, by the test case generation module of the processing subsystem, the generated test cases into at least one of a plurality of test suites, including regression test cases, security test cases, and negative test cases;
• executing, by a test execution and learning module of the processing subsystem, the generated test cases and collecting results of the execution, learning from the collected results of the executed test cases on a system under test;
• and
• enabling, by the test execution and learning module of the processing subsystem, the user to override the generated test cases upon providing an input by the user in relation to the at least one of the predefined set of semantic profiles and the custom semantic profile.
