Quality Assurance Awareness in Open Source Software Projects on GitHub

Software engineers employ a variety of approaches to ensure the quality of software systems, including software testing, modern code review, automated static analysis, build automation, and continuous integration. To make effective decisions regarding quality assurance (QA), software engineers need to have an awareness of (1) the QA approaches...

When to Let the Developer Guide: Trade-offs Between Open and Guided Test Amplification

Test amplification generates new tests by mutating existing, developer-written tests and keeping those tests that improve the coverage of the test suite. Current amplification tools focus on starting from a specific test and propose coverage improvements all over a software project, requiring considerable effort from the software engineer to...

Generating Understandable Unit Tests through End-to-End Test Scenario Carving

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...

Removing Redundant Statements in Amplified Test Cases

Test amplification generates new tests by modifying existing, manually written tests.<br/>Up until now, this process preserves statements that were relevant for the original test case but are no longer needed for the behavior of the new test case.<br/>These unnecessary statements impact the readability of the tests in question.<br/>As a part of...

Naming Amplified Tests Based on Improved Coverage

Test amplification generates new test cases that improve the coverage of an existing test suite. To convince developers to integrate these new test cases into their test suite, it is crucial to convey the behavior and the improvement in coverage that the amplified test case provides. In this paper, we present NATIC, an approach to generate names...
