Late (wildcard) variables don't get evaluated until they're read, so when we lower them, we should be lowering all of them to EmptyExpressions regardless of if they have an initializer expression.

Overview
The testcases in this directory and its subdirectory are all compiled in various different configurations designed to test various aspects of Fasta (or more generally, package:front_end).
The configurations are described below.
The source of truth for these configurations is the file pkg/front_end/testing.json.
Updating all expectations
To update test expectations for all tests at once, run:
dart pkg/front_end/tool/update_expectations.dart
Note that this takes a long time and should only be used when many tests need updating.
Updating expectations for a single test
To update the expectations for a specific test, provide the folder and test name as an argument.
For example, if you want to update the test expectations for a test, such as pkg/front_end/testcases/general/abstract_instantiation.dart, then run:
dart pkg/front_end/tool/update_expectations.dart general/abstract_instantiation
Updating expectations for all tests in a folder
If you want to update the test expectations for a specific folder of tests such as the pkg/front_end/testcases/general/ folder, then run:
dart pkg/front_end/tool/update_expectations.dart general/...
Dart 1.0 Outlines
- Status file: outline.status
- Standalone test: pkg/front_end/test/fasta/outline_test.dart
- Expectation prefix:
.outline.expect - How to update expectations:
./pkg/front_end/tool/fasta testing -DupdateExpectations=true outline/test1 outline/test2 ...
Dart 2.0 (strong mode)
- Status file: strong.status
- Standalone test: pkg/front_end/test/fasta/strong_test.dart
- Expectation prefix:
.strong.expect - How to update expectations:
./pkg/front_end/tool/fasta testing -DupdateExpectations=true -DupdateComments=true strong/test1 strong/test2 ...
Note: strong mode configuration additionally parses comments in the test file and can precisely match internal details of the compiler such as the inferred type of an expression or if a warning was emitted at a given location.
