It was an honor to receive the award for the best #VISSOFT2022 artifact #ICSME2022 's ROSE festival 🥳🙏🏼😊 Thank you for everyone who came by to see our visualization! Curious about a graph that shows behavior and impact of your test? 👇🏼 youtu.be/R5KDR_viFRA

I'm on the job market! I design, build, and evaluate human-AI systems with a focus on human-centered criteria such as understandability, effectiveness, & reliability. I'm interested in both industry and academic positions. Please reach out if you know of relevant opportunities!

- some additional coverage far away, other is not? → far coverage might be accidental! → it'll not be helpful to understand the intent of the test case. 👉🏼 We should look into more fine-grained coverage criteria that take test-distance into account 👈🏼

Developers can use this to decide on refactoring tests: - line only covered by far coverage? → likely not covered by a dedicated unit test - additional coverage only in far away methods? → possibly adapt new test case to a more specific unit test

3) Thanks to our visualization we gained a new way to look at additional/differential coverage: How far away is this coverage from the test case? close → more unit-test-like far → more integration-test -like

2) It's difficult to visualize added instruction coverage using line highlighting were instructions on the line covered before? which? are all instructions covered now? which not? 👉🏼 We need a precise way to visualize covered instructions with the source code 👈🏼

👉🏼 We need to develop a visualization that gives them *access* to this information 👈🏼 Challenge for the future: how do we provide access to the information in a way they find it, but without overwhelming them by just showing it always?

1) Developers are interested in a lot of varied information about the test cases For example: - control flow in & between methods - parameter and variable values - which other tests execute this code? - should we cover this code ?

Our prototype was the basis for our think-aloud experiment 🔬 Goal: understand better how we should build such a visualization for test case inspection. Participant's task: "Describe what scenario is newly covered by this test case. " Main results 👇🏼

By default: showing only executed methods with additional/new coverage and their connection to the test. The developer can interactively open method call branches to understand what happens during the test execution.
