Run 1

The code exhibits poor readability due to several factors. The structure appears tangled with incomplete context (the opening of the first loop is missing), and the nested try-catch blocks with empty catch clauses make error handling ambiguous. The while loop with an empty condition and incremental timeout pattern is non-idiomatic and unclear. Each loop contains multiple actions, reducing action granularity. Variable names like 'second' are poorly chosen, and repeated code blocks for similar timeout checks suggest poor abstraction. The reading flow is disrupted by abrupt exception handling and unclear break/continue logic.

Run 2

The code exhibits moderate readability but suffers from several structural issues. It uses deeply nested control flow with try-catch blocks that silently swallow exceptions, reducing clarity of intent. The polling loops are somewhat disorganized, with unclear magic numbers (90 seconds, 1000ms) and redundant visibility checks. Action granularity is acceptable, but the empty catch blocks and repeated polling patterns make the code unnecessarily long and ambiguous. Logical organization is weak—no helper methods or comments to explain the sign-out/sign-in verification process. Nesting depth is moderate but could be flattened. The reading flow is interrupted by empty exception handlers and lack of abstraction. Overall, the code is understandable but would benefit from refactoring the polling logic into a reusable method and handling exceptions explicitly.

Run 3

The code lacks overall structure and starts mid-logic, making it difficult to understand context. It contains deeply repetitive polling loops with swallowed exceptions, weakening clarity and error handling. The intent is partially clear—waiting for UI elements—but the absence of helper functions or comments makes it ambiguous. Lines are mostly concise, but repeated try-catch blocks and long waits add unnecessary length. Each line generally performs one action, yet the empty catch blocks and nested conditionals hinder readability. Reading flow is disrupted by abrupt variable names like 'second' and magic numbers such as 90 and 1000, which would benefit from named constants or configuration. Overall, the code works but lacks maintainable structure, clear logging, and abstraction, resulting in a low readability score.

Run 1

Code Structure: The sign-out action and subsequent sign-in visibility check are logically sequenced, but the fragment starts mid-loop and duplicates polling logic. Nesting: Moderate nesting within the loop and try/if blocks is manageable. Clarity of intent: Selenium calls make the logout workflow apparent, but empty catch blocks hide failures, and hard-coded timeouts lack explanation. Code length: Fairly concise, though a reusable wait helper could reduce repetition. Action granularity: Each statement performs one action, supporting readability. Reading flow: Sequential actions and whitespace help, but incomplete opening context, unusual infinite-loop syntax, and silently swallowed exceptions interrupt understanding.

Run 2

Code Structure: The sign-out action and subsequent polling are logically ordered, but the snippet starts mid-block and duplicates polling logic. Nesting: Loop, try, and conditional blocks create moderate nesting that remains manageable. Clarity of intent: Selenium calls clearly indicate signing out and waiting for Sign In, but empty catch blocks conceal failures, and magic timeout values lack explanation. Code length: Relatively short, though a reusable wait helper could eliminate boilerplate. Action granularity: Each statement performs a single action, making individual steps easy to identify. Reading flow: The sequence is mostly natural, with whitespace separating stages, but the incomplete opening context, silent exception handling, and unconventional infinite-loop syntax interrupt comprehension.

Run 3

Code Structure: The sign-out action and subsequent polling are logically ordered, but the snippet begins inside an omitted loop, reducing structural completeness. Nesting: Loop, try, and if blocks create moderate nesting. Clarity of intent: Selenium calls clearly express signing out and waiting for the sign-in control, but empty exception handlers hide failures, and hard-coded timeout values lack explanation. Code length: Fairly concise, although repeated polling logic could be extracted into a helper. Action granularity: Each statement generally performs one action, aiding readability. Reading flow: Sequential actions and consistent formatting make the flow understandable, but exception-driven polling, an infinite-loop header, and missing opening context interrupt it.
