Automated SQL Test Case Generator Using Syntax Permutations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual creation and execution of a large set of test cases for SQL queries is inefficient and time-consuming, as it lacks automation in generating and validating permutations of syntax elements for comprehensive database query testing.
Innovation Solution
A computer-implemented method and system that receives a mark-up language-based description of a syntax diagram, uses a parser to validate and generate permutations of elements, and stores test case queries on a computer-readable medium, enabling automated generation and validation of SQL test cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual creation of test cases is used, then test case coverage can be achieved, but the process is inefficient and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-defining syntax diagrams and language elements in a mark-up language format before test case generation. The system parses these predefined syntax definitions and automatically generates all possible test case permutations, eliminating the need for manual test case creation while ensuring comprehensive coverage of all syntax variations.
Solution Approach 2:
The system applies self-service by using automated parsers and permutation calculation algorithms to generate test cases from syntax definitions without human intervention. The computer reads the mark-up language descriptions, validates the syntax diagrams, and autonomously generates the complete set of test case queries, replacing manual test case development with self-automated processes.
2Reliability
If comprehensive test case coverage is pursued, then SQL component validation is improved, but the number of test cases becomes very large
Solution Approach 1:
The patent applies segmentation by breaking down the SQL syntax into discrete language elements and variations that can be independently defined in the mark-up language. Each syntax component is segmented and represented as a separate element in the syntax diagram, allowing the system to systematically generate test cases by combining these segmented elements according to the defined syntax rules.
Solution Approach 2:
The system applies universality by creating a generic test case generation framework that can handle any SQL syntax diagram defined in the mark-up language. The parser and permutation calculation mechanisms are designed to work universally with different syntax definitions, making the system adaptable to various SQL dialects and syntax variations without requiring custom test case generation logic for each scenario.
3Productivity
If automated generation of test cases is implemented, then efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a mark-up language as an intermediate representation layer between the SQL syntax definitions and the test case generation process. This intermediate format allows syntax diagrams to be described in a structured, parser-friendly manner, simplifying the automation process. The mark-up language acts as a mediator that translates human-readable syntax definitions into a format suitable for automated parsing and permutation calculation.

AI summary
A system and computer implemented method includes receiving an input file containing a mark-up language based description of a syntax diagram having multiple elements and variations for multiple elements describing a set of test case queries, checking and validating the syntax diagram via a parser running on a processor, and generating and storing, on a computer readable medium, the set of test case queries by calculating permutations of the elements in the syntax diagram.
