{#- Java test method template for JUnit 5
Context variables:
- method_name: method name (UpperCamelCase)
- description: fixture description
- builder_expressions: string containing pre-generated builder expressions (or empty)
- setup_lines: list of setup line strings (e.g., handle creation)
- throws_clause: " throws Exception" or ""
- expects_error: boolean
- declared_error_check: string containing the rendered declared-value assertion, or empty
- call_expr: the complete function call expression
- result_var: result variable name
- returns_void: bool — whether the call returns void (Rust `()` / `Result<(),E>`)
- void_not_error: bool — returns_void call whose only meaningful check is `not_error`;
wraps call_expr in assertDoesNotThrow so the check is a real, visible assertion instead
of a bare statement
- assertions_body: string containing all rendered assertions
- unrenderable_error_assertions: skip markers for error-path assertions this backend cannot render
#}

// the C# `Assert.ThrowsAnyAsync(() => client.X(Type.FromJson(...)))`
// pattern.
