Tackle-test also leverages some existing and commonly used test-generation strategies to maximize code coverage. The test plan can be generated at different, user-configurable interaction levels, where higher levels result in the generation of more test cases and more thorough testing, but at the cost of increased test-generation time. It then generates a test plan consisting of coverage goals from the model and synthesizes test sequences for covering rows of the test plan. A CTD algorithm automatically constructs a subset of the set of valid tests to cover all legitimate value combinations of every t parameters, where t is usually a user input.Īlthough CTD is typically applied to program inputs in a black-box manner and the CTD model is created manually, Tackle-test automatically builds a parameter-type-based white-box CTD model for each method under test. A valid test in the test space is defined as an assignment of one value to each parameter that satisfies the constraints.

It typically requires a manual definition of the test space in the form of a CTD model, consisting of a set of parameters, their respective values, and constraints on the value combinations. CTD is a well-known, effective, and efficient test-design technique. Tackle-test uses a novel test-generation technique that applies combinatorial test design (CTD)-also called combinatorial testing or combinatorial interaction testing -to method interfaces, with the goal of performing rigorous testing of methods with “complex interfaces,” where interface complexity is characterized over the space of parameter-type combinations that a method can be invoked with.

Overview of Tackle-testĪt its core, Tackle-test is an automatic generator of unit test cases for Java applications.
Tackle-test is an automated testing tool designed to address this challenge. In some reported case studies, testing accounted for approximately 70% to 80% of the time spent on modernization projects. Therefore, validation is mainly done manually in most modernization projects-it is a process that is time-consuming and may not test the application sufficiently. A poorly maintained test suite might also contain many obsolete tests (accumulated over time as the application evolved). Legacy applications often do not have automated test cases, or, if available, test coverage might be inadequate, both in general and specifically for covering modernization-related changes. Unfortunately, this can be tedious and hard to perform. One of the key tasks is validating that the modernized application preserves the functionality of the legacy application. Modernizing and transforming legacy applications is a challenging activity that involves several tasks.
