# 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.
