Struct ParserTester 

pub struct ParserTester { /* private fields */ }

A concurrent parser testing utility that can run tests against multiple files with timeout support.

The ParserTester provides functionality to test parsers against a directory of files with specific extensions, comparing actual output against expected results stored in JSON files, with configurable timeout protection.

Implementations

impl ParserTester

pub fn new<P: AsRef<Path>>(root: P) -> Self

Creates a new parser tester with the specified root directory and default 10-second timeout.

pub fn with_extension(self, extension: impl ToString) -> Self

Adds a file extension to test against.

pub fn with_timeout(self, timeout: Duration) -> Self

Sets the timeout for parsing operations.

Arguments

• timeout - The maximum duration to wait for parsing to complete

Returns

A new ParserTester with the specified timeout

pub fn run_tests<L, P>(self, parser: &P) -> Result<(), OakError>

where P: Parser<L> + Send + Sync, L: Language + Send + Sync, L::SyntaxKind: Serialize + Debug + Sync + Send,

Run tests for the given parser against all files in the root directory with the specified extensions.

Arguments

• parser: The parser to test.

Examples

use oak_core::helpers::parsing::ParserTester;

let tester = ParserTester::new("tests/parser").with_extension("tex");
tester.run_tests(my_parser)?;
