Pattern B: @Given("^the user has (\\d+) items worth \\$(\\d+) in their basket$") What is the structural issue causing this runtime collision, and what is the cleanest programmatic remedy?

A) Cucumber cannot interpret regular expressions and Cucumber expressions inside the same project runtime environment.

B) The literal dollar sign in Pattern A is conflicting with the regex end-of-string anchor symbol $, causing both expressions to evaluate identically against the target string.

C) The execution engine matches both methods to the exact same text string because both definitions resolve to identical capture sequences for the integers.

D) The step definition file lacks an explicit priority parameter within its annotation structure to arbitrate which pattern runs first.

E) Pattern B is failing because the escaped backslashes for digits are not supported within standardized Java or JavaScript regular expression string wrappers.

F) The test runner cannot process data expressions containing multiple variables unless they are explicitly passed via a structured data table format.

Why it is correct: Cucumber throws an AmbiguousStepDefinitionsException when the text string inside a feature file matches more than one defined step pattern during execution. In this scenario, both the Cucumber expression in Pattern A (using {int}) and the standard Regular Expression in Pattern B (using (\d+)) successfully parse the exact same text sequence. Since Cucumber does not inherently prioritize one style over the other, it stops execution to prevent unintended side effects.

Why alternative options are incorrect:

Option B is incorrect: While the dollar sign is a special character, standard escaping avoids structural confusion; it does not cause a dual-match signature collision on its own.

Option D is incorrect: Cucumber step definitions do not possess an inline "priority" or "weight" attribute within standard annotations to bypass unambiguous match errors.

Option E is incorrect: Escaped backslashes are standard syntax requirements for representing regex digit matchers within multi-language string blocks.

Option F is incorrect: Step lines are fully capable of capturing multiple inline variable primitives without forcing a migration to multi-row data tables.

Method 2: @Before(order = 1)

Method 3: @After(order = 2)

Method 4: @After(order = 1) Assuming a single scenario executes without throwing an intermediate crash, in what explicit sequential order will these four hooks execute relative to the core step execution?

A) Method 2 -> Method 1 -> [Scenario Steps Execution] -> Method 4 -> Method 3

B) Method 1 -> Method 2 -> [Scenario Steps Execution] -> Method 3 -> Method 4

C) Method 1 -> Method 2 -> [Scenario Steps Execution] -> Method 4 -> Method 3

C) Method 2 -> Method 1 -> [Scenario Steps Execution] -> Method 3 -> Method 4

E) All @Before hooks execute simultaneously via background parallel threads, followed by steps, followed by all @After hooks.

F) Method 1 -> Method 2 -> [Scenario Steps Execution] -> Both @After hooks run concurrently based on system thread safety settings.

Why it is correct: In Cucumber, @Before hooks run in ascending order based on their designated integer value (lowest number executes first). Conversely, @After hooks execute in descending order (highest number executes first) to create a standard "Last In, First Out" teardown pattern. Therefore, Method 2 (order = 1) runs before Method 1 (order = 2). After the step definitions complete, Method 3 (order = 2) runs before Method 4 (order = 1).

Why alternative options are incorrect:

Option B is incorrect: This suggests an ascending flow for both setup and teardown, which disrupts standard cleanup dependencies.

Option C is incorrect: This sequence treats both cycles incorrectly, violating the engine's built-in ordering framework rules.

Option E is incorrect: Hooks within a single scenario block run sequentially within a single thread context to prevent critical state race conditions.

Option F is incorrect: Teardown blocks are strictly deterministic and run sequentially rather than branching into unpredictable parallel threads.

B) DataTables automatically compile down into a parallel-execution format at runtime, whereas Examples blocks must run sequentially.

C) A Scenario Outline terminates the entire feature execution if row 3 fails, while a DataTable skips errors to run remaining items.

D) Examples tables are strictly restricted to capturing alpha-numeric text strings, whereas DataTables can parse multi-layered JSON payloads directly.

E) The Examples block structure requires an external file connection like Excel, while a DataTable is always coded inline.

F) Scenario Outlines require a separate step definition pattern for every unique data row present within the testing criteria block.

Why it is correct: This is a fundamental lifecycle difference. When using a Scenario Outline with an Examples: block, the Cucumber engine instantiates, runs, and tears down the entire scenario lifecycle (including running all @Before and @After hooks) for every individual data row. When utilizing a DataTable inside a standard step, the scenario runs exactly once, and the collection of data is managed entirely within that single step definition method.

Why alternative options are incorrect:

Option C is incorrect: If an item in a DataTable fails without explicit error wrapping, the single scenario stops immediately. In contrast, subsequent rows in a Scenario Outline continue executing independently.

Option D is incorrect: Both structures accept basic tabular strings, which are then parsed into specific programmatic datatypes by the framework.

Option E is incorrect: Examples: tables are natively defined inline beneath the outline steps using standard pipe delimiters.

Option F is incorrect: A Scenario Outline maps to a single set of step definitions, dynamically injecting values using placeholder headers like <variableName>.
