Automatically generate test cases from boundary values of input parameters. Efficiently test areas where bugs are likely to occur.
Set the parameter name, minimum, and maximum values. Use presets or add manually.
Choose Normal (boundaries only), Robust (include outside), or Comprehensive.
Click "Generate Test Cases" to create boundary value test cases and export in CSV or Markdown format.
Set the valid range for each parameter
Boundary Value Analyzer is an online tool that automatically generates boundary value test cases from the valid range of input parameters. Since software bugs often occur near boundaries, boundary value testing is crucial for quality assurance. You can choose from three analysis types: Normal, Robust, and Comprehensive to efficiently create test cases.
Boundary value analysis is a testing technique that tests the boundaries of valid input ranges (minimum and maximum values and their neighbors). Since program bugs often occur at boundary conditions, it enables efficient bug detection.
Normal tests only min and max values. Robust tests both inside and outside boundaries (min-1, min, max, max+1). Comprehensive tests all boundary +/-1 values (min-1, min, min+1, max-1, max, max+1).
Values within the configured min-max range are valid, and values outside are invalid. Invalid value test cases are used to verify that the system properly handles errors.
Set the data type to 'Decimal' and specify the precision in the Step field. For example, setting 0.1 generates test cases at boundary +/-0.1.
Download in CSV format for use in Excel or test management tools, or copy in Markdown format to paste into documentation. Use them as a checklist during test execution.
