PackageContextForTest class
Creates a temporary directory with a pubspec using the test_descriptor
package, installs dependencies with dart pub get, and sets up an analysis
context for the package.
Source files can then be added to the package with addFile, which will return a FileContext wrapper for use in tests.
Use this to setup tests for Suggestors that require the resolved AST, like
the AstVisitingSuggestor when shouldResolveAst() returns true. Doing so
will enable the analyzer to resolve imports and symbols from other source
files and dependencies.
test('MySuggestor', () async {
var pkg = await PackageContextForTest.fromPubspec('''
name: pkg
version: 0.0.0
environment:
sdk: '>=3.0.0 <4.0.0'
dependencies:
meta: ^1.0.0
''');
var context = await pkg.addFile('''
import 'package:meta/meta.dart';
@visibleForTesting var foo = true;
''');
var suggestor = MySuggestor();
var expectedOutput = '...';
expectSuggestorGeneratesPatches(suggestor, context, expectedOutput);
});
