- Around line 24-31: The is_describe_call function currently treats any member
call ending in "describe" as a test suite (e.g., foo.describe()), which is too
permissive; change the logic in is_describe_call to first split
callee.to_trimmed_text() into first and second segments and only accept the
second == "describe" case when the first segment is a known test root (e.g.,
"test", "it", or "describe"), i.e., return true if first is one of "describe" |
"fdescribe" | "xdescribe" OR (second == Some("describe") && first is one of the
allowed roots like "test" | "it" | "describe"); update the matching expression
in is_describe_call accordingly.

In `@crates/biome_js_analyze/src/lint/nursery/no_identical_test_title.rs`:
- Around line 219-230: The extraction currently ignores no-substitution template
literals, so update extract_call_title to also recognize template literal nodes
(e.g., match AnyJsExpression variants representing template literals with a
single quasi and no substitutions) and return their static inner text just like
JsStringLiteralExpression; locate the match in extract_call_title and add a
branch that extracts the template text (using the same inner_string_text() or
equivalent accessor) for single-quasi templates, then add a test fixture that
uses it(`same title`, ...) to ensure duplicate detection catches backtick
no-substitution templates.

Nitpick comments:
In @.changeset/add-no-identical-test-title.md:
- Line 5: The changeset text includes upstream implementation detail ("porting
`jest/no-identical-title` and `vitest/no-identical-title`") that should be
removed; edit the changeset entry for nursery/noIdenticalTestTitle to keep only
the user-facing behavior description ("This rule disallows using the same title
for two `describe` blocks or two test cases at the same nesting level.") and
remove the trailing "porting ..." clause so the description targets end users
rather than developers.

In `@crates/biome_rule_options/src/no_identical_test_title.rs`:
- Around line 3-6: Add a one-line inline rustdoc comment to the
NoIdenticalTestTitleOptions struct to document its purpose (e.g., "Options for
the no_identical_test_title rule.") by placing a /// comment directly above the
pub struct NoIdenticalTestTitleOptions {} declaration; keep it brief and follow
existing docs style used for other rule option types.

In `@crates/biome_js_analyze/src/frameworks/unit_tests.rs`:
- Around line 27-77: The matcher in is_describe_call currently only accepts a
bare "describe" identifier or a single static member whose right-most segment is
"describe", so chained modifier forms like describe.only, describe.skip, and
test.describe.only fall through; update is_describe_call to unwrap
AnyJsExpression::JsStaticMemberExpression chains (traverse member().object()
recursively) to find the right-most name token and accept it if the final
identifier is "describe", then allow additional member segments after that
(e.g., "only", "skip") by treating any further static-member chain as part of
the same describe scope; reference the is_describe_call function, the callee
variable, and AnyJsExpression::JsStaticMemberExpression/member/object traversal
when implementing the change, and add snapshot tests covering describe.only,
describe.skip, test.describe.only, and similar variants under
tests/specs/{group}/{rule}/ to ensure duplicates inside these modified suites
are detected.

Nitpick comments:
In `@crates/biome_rule_options/src/no_identical_test_title.rs`:
- Around line 3-6: Add inline rustdoc to the NoIdenticalTestTitleOptions type to
document that this rule has no configurable options; update the doc comment
immediately above the pub struct NoIdenticalTestTitleOptions {} to a concise
sentence like "Options for the `no_identical_test_title` rule — this rule has no
configurable options." so the generated config/schema surface clearly
communicates there are no options; keep the comment as normal Rust doc (///) and
place it directly above the struct definition.

Duplicate comments:
In `@crates/biome_js_analyze/src/frameworks/unit_tests.rs`:
- Around line 27-78: is_describe_call currently only matches bare describe(...)
or a single JsStaticMemberExpression ending in "describe" and thus misses
chained modifiers like describe.only(...), describe.skip(...), or
test.describe.only(...); update is_describe_call to walk/unwind a chain of
JsStaticMemberExpression on the callee (peeling right-hand members) until you
find the terminal name token and confirm that one of the identifiers in the
chain is "describe" and that any preceding root object is one of the known test
roots ("test", "it", "describe"); treat modifier names ("only", "skip", "each",
etc.) as valid intermediate members rather than failing the match; update the
logic in is_describe_call (and where it checks member().object() and
member().member()) to traverse nested JsStaticMemberExpression nodes, and add
snapshot tests under tests/specs/{group}/{rule}/ covering describe.only,
describe.skip, describe.each, test.describe.only, and chained combinations so
lint rules detect duplicates inside these modified describe blocks.

In `@crates/biome_js_analyze/src/frameworks/unit_tests.rs`:
- Around line 20-26: The docstring falsely claims support for
describe.each(...); fix by updating the matching logic used where
member_is_describe is checked so JsStaticMemberExpression callees also accept
the "each" modifier chain: treat a callee as a describe when either the property
name is "describe" OR the property name is "each" and its object is the
identifier or static member whose final property is "describe" (i.e. allow
patterns like describe.each(...) and test.describe.each(...)); update the check
in the function that uses member_is_describe to recognize this modifier chain
(or alternatively change the docstring to remove the claim if you prefer not to
implement the modifier handling).

In `@crates/biome_js_analyze/src/lint/nursery/no_identical_test_title.rs`:
- Around line 218-229: The code currently maintains a redundant suppression
mechanism (suppressed_scopes / suppressed_nodes) that hides nodes which never
produce signals because scope_statements_for_call already requires a JsScript
parent and nested describes cannot satisfy that; remove the suppressed_scopes
and suppressed_nodes data structures and all code that populates or checks them
(references to suppressed_scopes, suppressed_nodes, and any early returns or
skips based on them) and simplify the signal-generation flow to rely solely on
scope_statements_for_call (and functions it calls like module_statements) so
nodes that naturally return None are simply not signaled; ensure related tests
or comments that referenced suppression are updated or removed.

Nitpick comments:
In `@crates/biome_js_analyze/src/lint/nursery/no_identical_test_title.rs`:
- Around line 175-209: Replace the O(n) Vec lookups for duplicate title
detection with a HashSet: change describe_titles and test_titles to
HashSet<TokenText> (or the actual title type), import std::collections::HashSet,
and when you extract a title in scan_scope use set.insert(title.clone()) (or
check the return value) to determine if it was already present and then push the
call into duplicates; remove the Vec::contains checks and the pushes that add
titles to the vecs and instead insert into the corresponding HashSet; keep
duplicates and suppressed_scopes as Vecs and preserve the behavior around
describe_body_statements, call_from_statement, is_describe_call, is_unit_test,
extract_call_title, and scan_scope while ensuring you clone or borrow titles as
needed to satisfy ownership.
