A Method of Making Single Function Tests for Constituting Scenario Tests

In designing scenario tests, it is difficult to suppose how the target software will be used. We regard a scenario test as testing a flow of multiple functions. And we propose a method to design scenario tests by combining single function tests in a structured way. In our method, a single-function test consists of one trigger and some conditions. In this way, the single-function tests are easily combined for designing scenario tests. Our method can generate single-function tests for each function and scenario tests in a systematic manner at low cost.
