This paper reports the results of the deployment of Rich-State Simulated Populations at Meta for both automated and manual testing. We use simulated users (aka test users) to mimic user interactions and acquire state in much the same way that real user ...

Code comments are important artifacts in software systems and play a paramount role in many software engineering (SE) tasks related to maintenance and program comprehension. However, while it is widely accepted that high quality matters in code ...

• The studies in the last decade (2011–2020) analyze comments of multiple systems.
• 87% of the studies analyze comments from Java systems.
• 50% of the studies focus on specific comment types, e.g., method, or inline.
• 21 quality ...

A class may need to obey temporal constraints in order to function correctly. For example, the correct usage protocol for an iterator is to always check whether there is a next element before asking for it; iterating over a collection when there are no ...

Code comments are the primary means to document implementation and facilitate program comprehension. Thus, their quality should be a primary concern to improve program maintenance. While much effort has been dedicated to detecting bad ...

• Comment clones can be a bad practice just as code clones
• They may represent ...

Software testing depends on effective oracles. Implicit oracles, such as checks for program crashes, are widely applicable but narrow in scope. Oracles based on formal specifications can reveal application-specific failures, but ...

• Automatically deriving metamorphic relations is relevant for software testing.
• ...

Procedure specifications are useful in many software development tasks. As one example, in automatic test case generation they can guide testing, act as test oracles able to reveal bugs, and identify illegal inputs. Whereas formal specifications are ...

Code comments are the primary means to document implementation and ease program comprehension. Thus, their quality should be a primary concern to improve program maintenance. While a lot of effort has been dedicated to detect bad smell in code, little ...
