The enum had six reasons and the code needed a seventh
Up front, the weakest part of this story: when I re-injected the defect I'm about to describe, every runtime test in the workspace stayed green. The only thing that went red was a source scan, a test that reads the pipeline file as text and checks each construction site. If your instinct is that source-scan gates are a smell, hold that thought, because the runtime test that catches this case…
During a recent development, a team encountered a critical issue in their codebase related to a rollback operation. The team had six established reasons for declining to attempt a rollback, but when the code was re-injected, it revealed a seventh reason that had previously gone unnoticed. The source scan test, which verifies the pipeline file as text, caught this issue and highlighted the need for a new variant in their enumeration.
After thorough examination, they determined that the seventh reason, "PromisedPostStateWasWrong," best described the situation. This addition not only addressed the existing issue but also prevented potential future problems. Implementing this change required minimal modifications, adding only a new possible string to a diagnostic member.
The update was seamlessly integrated without causing any additional runtime failures, ensuring the code's integrity and reliability.
