Struct GoldenFile 

pub struct GoldenFile {
    pub name: String,
    pub source: String,
    pub expected_ast: String,
    pub actual_ast: Option<String>,
}

A single golden-file test: parse source and compare the printed AST against expected_ast.

The expected_ast should match the output of print_decl exactly (modulo normalised whitespace).

Fields

name: String

Descriptive test name.

source: String

OxiLean source snippet to parse.

expected_ast: String

Expected pretty-printed AST string.

actual_ast: Option<String>

Populated by check with the actual printed AST.

Implementations

impl GoldenFile

pub fn new(name: &str, source: &str, expected_ast: &str) -> Self

Create a new golden-file test.

pub fn check(&mut self) -> bool

Parse self.source, store the result in actual_ast, and return true iff the normalised printed form matches expected_ast.

pub fn diff(&self) -> Option<String>

Returns None when actual_ast matches expected_ast, otherwise a short diff description.
