build_test 0.9.2

build_test: ^0.9.2 copied to clipboard

• Add inputExtension argument to CopyBuilder. When used the builder with throw if any assets are provided that don't match the input extension.

• Allow build_barback version 0.5.x. The breaking behavior change should not impact test uses that don't already have a version constraint on that package.

• Added the TestBootstrapBuilder under the builder.dart library. This can be used to bootstrap tests similar to the test/pub_serve Transformer.
  • Known Issue: Custom html files are not supported.
• Breaking: All AssetReader#findAssets implementations now return a Stream<AssetId> to match the latest build package.
• Breaking: The DatedValue, DatedString, and DatedBytes apis are now gone, since timestamps are no longer used by package:build. Instead the InMemoryAssetReader and other apis take a Map<AssetId, dynamic>, and will automatically convert any String values into List<int> values.
• Breaking: The outputs map of testBuilder works a little bit differently due to the removal of DatedValue and DatedString.
  • If a value provided is a String, then the asset is by default decoded using UTF8, and matched against the string.
  • If the value is a matcher, it will match againt the actual bytes of the asset (in List<int> form).
  • A new matcher was added, decodedMatches, which can be combined with other matchers to match against the string contents. For example, to match a string containing a substring, you would do decodedMatches(contains('some substring')).

• InMemoryAssetReader, MultiAssetReader, StubAssetReader and PackageAssetReader now implement the MultiPackageAssetReader interface.
• testBuilder now supports Builders that call findAssets in non-root packages.
• Added a GlobbingBuilder which globs files in a package.
• Added the RecordingAssetReader interface, which adds the Iterable<AssetId> get assetsRead getter.
• InMemoryAssetReader now implements RecordingAssetReader.
• Breaking: The MultiAssetReader now requires all its wrapped readers to implement the MultiPackageAssetReader interface.
  • This should not affect most users, since all readers provided by this package now implement that interface.

• Add mapAssetIds argument to checkOutputs for cases where the logical asset location recorded by the builder does not match the written location.

• Add recordLogs, a top-level function that invokes scopeLog and captures the resulting Stream<LogRecord> for testing. Can be used with the provided anyLogOf, infoLogOf, warningLogOf, severeLogOf matchers in order to test a build process:

test('should log "uh oh!"', () async {
  final logs = recordLogs(() => runBuilder());
  expect(logs, emitsInOrder([
    anyLogOf('uh oh!'),
  ]);
});

• Add the constructors forPackages and forPackageRoot to PackageAssetReader - these are convenience constructors for pointing to a small set of packages (fake or real) for testing purposes. For example:

test('should resolve multiple libraries', () async {
  reader = new PackageAssetReader.forPackages({
    'example_a': '_libs/example_a',
    'example_b': '_libs/example_b',
  });
  expect(await reader.canRead(fileFromExampleLibA), isTrue);
  expect(await reader.canRead(fileFromExampleLibB), isTrue);
  expect(await reader.canRead(fileFromExampleLibC), isFalse);
});

• Switch to a typedef from function type syntax for compatibility with older SDKs.

• Breaking: resolveSource and resolveAsset now take an action to perform with the Resolver instance.

• Allow package:build_barback v0.4.x

• Allow package:build v0.10.x
• AssetReader implementations always return Future from canRead

• Added resolveAsset, which is similar to resolveSource but specifies a real asset that lives on the file system. For example, to resolve the main library of package:collection:

var pkgCollection = new AssetId('collection', 'lib/collection.dart');
var resolver = await resolveAsset(pkgCollection);
// ...

• Supports package:build_barback >=0.2.0 <0.4.0.

• Internal version bump.

• Declare an output extension in _ResolveSourceBuilder so it is not skipped

• Support build 0.9.0
  • Rename hasInput to canRead in AssetReader implementations
  • Replace declareOutputs with buildExtensions in Builder implementations
• Breaking CopyBuilder no longer has an outputPackage field since outputs can only ever be in the same package as inputs.

• Add MultiAssetReader to the public API.

• Add PackageAssetReader, a standalone asset reader that uses a PackageResolver to map an AssetId to a location on disk.
• Add resolveSource, a top-level function that can resolve arbitrary Dart source code. This can be useful in testing your own code that uses a Resolver to do type checks.

• Add findAssets implementations to StubAssetReader an InMemoryAssetReader
• BREAKING: InMemoryAssetReader constructor uses named optional parameters

• Make scopeLog visible so tests can be run with an available log without going through runBuilder.

• Bug Fix: Correctly identify missing outputs in testBuilder

Updates to work with build version 0.7.0.

New Features #

• The testBuilder method now accepts List<int> values for both sourceAssets and outputs.
• The checkOutputs method is now public.

Breaking Changes #

• The testBuilder method now requires a RecordingAssetWriter instead of just an AssetWriter for the writer parameter.
• If a Matcher is provided as a value in outputs, then it will match against the same value that was written. For example if your builder uses writeAsString then it will match against that string. If you use writeAsBytes then it will match against those bytes. It will not automatically convert to/from bytes and strings.
• Deleted the makeAsset and makeAssets methods. There is no more Asset class so these don't really have any value any more.
• The signature of addAssets has changed to void addAssets(Map<AssetId, dynamic> assets, InMemoryAssetWriter writer). Values of the map may be either String or List<int>.
• InMemoryAssetReader#assets and InMemoryAssetWriter#assets have changed to a type of Map<AssetId, DatedValue> from a type of Map<AssetId, DatedString>. DatedValue has both a stringValue and bytesValue getter.
• InMemoryAssetReader and InMemoryAssetWriter have been updated to implement the new AssetReader and AssetWriter interfaces (see the build package CHANGELOG for more details).
• InMemoryAssetReader#cacheAsset has been changed to two separate methods, void cacheStringAsset(AssetId id, String contents) and void cacheBytesAsset(AssetId id, List<int> bytes).
• The equalsAsset matcher has been removed, since there is no more Asset class.

• Additional capabilities in testBuilder:
  • Filter sourceAssets to inputs with isInput
  • Get log records
  • Ignore output expectations when outputs is null
  • Use a custom writer

• BREAKING removed testPhases utility. Tests should be using testBuilder
• Drop dependency on build_runner package

• Support the package split into build/build_runner/build_barback
• Expose additional test utilities that used to be internal to build

• Upgrade build package to 0.4.0
• Delete now unnecessary GenericBuilderTransformer and use BuilderTransformer in the tests.

• Add logLevel and onLog named args to testPhases. These can be used to test your log messages, see test/utils_test.dart for an example.

• Allow String or Matcher for expected output values in testPhases.

• Initial version, exposes many basic utilities for testing Builders using in memory data structures. Most notably, the testPhases method.
