What test roles is a developer most likely to perform?

The most suitable test roles for a developer would involve executing component integration tests and performing static analysis. Developers are often deeply involved in the testing processes related to the components they build, which includes integration testing. This type of testing focuses on verifying the interactions between integrated components and ensuring they work together as expected.

Static analysis, on the other hand, is a technique used to evaluate code without actually executing it. Developers usually utilize static analysis tools to identify potential issues in their code, such as coding standard violations or possible bugs. This proactive approach helps to enhance code quality and preemptively fix problems before they transition into more complex integration or system testing stages.

The other scenarios, while they might involve testing aspects, are less directly tied to the core responsibilities that developers typically handle. For instance, deciding on the extent of automation might be a task more aligned with testers or test managers, while setting up the test environment is usually managed by dedicated roles within a testing team. Thus, the choice of executing component integration tests and static analysis accurately reflects the primary testing responsibilities commonly associated with developers.
