The invention discloses a combined test case generation method based on parameter abstract modeling, and belongs to the field of software engineering. The method comprises the steps of 1, preliminarily constructing a parameter abstract model; guaranteeing the integrity of abstract values by using a boundary value method to optimize the abstract model; 2, defining a relationship and constraints according to standards such as an association relationship between parameters, coverage strength and semantic correctness, then reducing constraint conditions by depending on the association relationship between the constraints and the association relationship between the constraint conditions and constraint objects, and finally completing construction of an abstract model; and 3, setting reasonable combination factors according to the abstract model, generating an abstract test case through a PICT combination test tool, then converting the abstract test case into a specific test case according to related rules, and then testing the program object. According to the method, the test efficiency is improved while the defect detection effect is ensured.
Description
technical field [0001] The invention belongs to the field of test case generation in software testing, and relates to a method for generating combined test cases based on parameter abstract modeling. Background technique [0002] In all stages of software testing, test case generation is one of the most important activities and also one of the most critical challenges, which has a great influence on the effectiveness and efficiency of the whole testing process. Among them, combined testing is one of the widely used test case generation methods. Combinatorial testing methods systematically cover the interactions among any τ parameters by carefully constructing a set of test cases. The study found that about 70% of the faults in software development are usually triggered by one parameter or the interaction between two parameters, and the parameters related to the fault are often no more than six. The input parameter model represents the input space of the system under test t...
