MockMontyPlatform class

A mock implementation of MontyPlatform for testing.

Configure expected return values before calling methods:

final mock = MockMontyPlatform();
mock.runResult = MontyResult(value: 42, usage: usage);
final result = await mock.run('1 + 1');
expect(mock.lastRunCode, '1 + 1');

For start, resume, and resumeWithError, enqueue progress values using enqueueProgress:

mock.enqueueProgress(MontyPending(functionName: 'fetch', arguments: []));
mock.enqueueProgress(MontyComplete(result: result));

Methods

cancel() → Future<void>
Cancels the current execution. Idempotent — safe to call multiple times.
override
dispose() → Future<void>
Releases resources held by this interpreter instance.
override
enqueueProgress(MontyProgress progress) → void
Adds a MontyProgress to the FIFO queue consumed by start, resume, resumeWithError, resumeAsFuture, and resolveFutures.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
resolveFutures(Map<int, Object?> results, {Map<int, String>? errors}) → Future<MontyProgress>
Resolves pending futures with their results, and optionally errors.
override
restore(Uint8List data) → Future<MontyPlatform>
Restores interpreter state from a binary snapshot data.
override
resume(Object? returnValue) → Future<MontyProgress>
Resumes a paused execution with the given returnValue.
override
resumeAsFuture() → Future<MontyProgress>
Resumes a paused execution by creating a future for the pending call.
override
resumeWithError(String errorMessage) → Future<MontyProgress>
Resumes a paused execution by raising an error with errorMessage.
override
run(String code, {MontyLimits? limits, String? scriptName}) → Future<MontyResult>
Executes code and returns the result.
override
snapshot() → Future<Uint8List>
Captures the current interpreter state as a binary snapshot.
override
start(String code, {List<String>? externalFunctions, MontyLimits? limits, String? scriptName}) → Future<MontyProgress>
Starts a multi-step execution of code.
override
toString() → String
A string representation of this object.
