Test case generation method for Go language

In software industry, the quality of software products should became a primary concern. One of many elements that affects to the software quality is testing. Creating a lot of test cases consumes a lot of time and tedious work. These issues can be solved by create a generator that automates the generation of input test data. Go language, or Golang for short, is a new programming language that developed by Google and has been used by many companies for their projects. However, Golang currently does not have any test generator that is able to generate test data with code coverage adequacy. In this research, we propose a process generation of test cases using Genetic Algorithm for Go language. We also have developed a tool based on this process generation. The tool does not only produce test data, but also the test code. By automating the generation, it is expected to reduce the amount of effort and time to generate manually. We have evaluated this process using eight different Golang source code. We found that the process and tool have facilitated the process of unit testing.
