Abstract

Automatic unit test generators such as EvoSuite are able to automatically generate unit test suites with high coverage. This removes the burden of writing unit tests from developers, but the generated tests are often difficult to understand for them. In this paper, we introduce the MicroTestCarver approach that generates unit tests starting from manual or scripted end-toend (E2E) tests. Using carved information from these E2E tests, we generate unit tests that have meaningful test scenarios and contain actual test data. When we apply our MicroTestCarver approach, we observe that 85% of the generated tests are executable. Through a user study involving 20 participants, we get indications that tests generated with MicroTestCarver are relatively easy to understand.
