# 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](../testing.json). ## Dart 1.0 Compilation * Status file: [legacy.status](legacy.status) * Standalone test: [pkg/front_end/test/fasta/legacy_test.dart](../test/fasta/legacy_test.dart) * Expectation prefix: `.direct.expect` * How to update expectations: ``` ./pkg/front_end/tool/fasta testing -DupdateExpectations=true compile/test1 compile/test2 ... ``` ## Dart 1.0 Outlines * Status file: [outline.status](outline.status) * Standalone test: [pkg/front_end/test/fasta/outline_test.dart](../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](strong.status) * Standalone test: [pkg/front_end/test/fasta/strong_test.dart](../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.
