build_test 3.3.0-dev.3

build_test: ^3.3.0-dev.3 copied to clipboard

• Read build configs using AssetReader so they're easier to test: you can now pass in build.yaml like any other asset.
• Bug fix: don't crash when a builder logs during a testBuilder or resolveSource call outside a test.
• Remove unused deps: async, convert.
• Remove unused dev_deps: collection.

• Files loaded from disk for resolveSources and testBuilders that are in the same package as explicitly-passed test inputs are now loaded if they match the default globs, such as lib/**, instead of ignored. This more closely matches version 2 behavior.

• Use build 3.0.0-dev.1.
• Use build_resolvers 3.0.0-dev.1.

• Fixes when passing a readerWriter to testBuilders: don't count initial assets as outputs; do set up packages for initial assets; only apply builders to packages mentioned in sourceAssets.
• Add readAllSourcesFromFilesystem parameter to resolveSources. Set it to true to make the method behave as it did in build_test 2.2.0.
• Fix to resolveSources error handling.

• Add inputsTrackedFor and resolverEntrypointsTrackedFor to ReaderWriterTesting, so tests can determine what each build step read and resolved.
• Add loadIsolateSources to ReaderWriterTesting. It loads all real sources visible to the test into memory.
• testBuilder default onLog now works outside of tests: it falls back to print instead of crashing.
• Update README.md.

Breaking changes:

• Breaking change: removed tearDown parameter to resolveSources for keeping resolvers across multiple tests.
• Breaking change: tests must use new TestReaderWriter instead of InMemoryAssetReader and InMemoryAssetWriter.
• Breaking change: testBuilder no longer accepts a reader and a writer. Instead it returns a TestBuilderResult with the TestReaderWriter that was used.
• Breaking change: resolveSources no longer automatically reads non-input files from the filesystem; specify explicitly which non-input files the test should read in nonInputsToReadFromFilesystem.
• Breaking change: remove MultiAssetReader. Load the source into one TestReaderWriter instead.
• Breaking change: TestReaderWriter.assetsRead does not take into account details of the build, it's just what was actually read. Use TestReaderWriter.inputsTracked for what was recorded as an input. Note that resolver entrypoints are now tracked separately from inputs, see TestReaderWriter.resolverEntrypointsTracked.
• Breaking change: Remove StubAssetReader. Use TestReaderWriter instead.

Other user-visible changes:

• resolveSources and testBuilder now do a full build_runner build, with configuration as much as possible based on the some parameters.
• Add testBuilders to run a test build with multiple builders.
• Add optionalBuilders to testBuilders to have some builders be optional.
• Add visibleOutputBuilders to testBuilders to have some builders write their output next to their inputs.
• Add testingBuilderConfig to testBuilders to control builder config override.
• Add resolvers parameter to testBuild and testBuilders.
• Add readerWriter and enableLowResourceMode parameters to testBuild and testBuilders.
• TestReaderWriter writes and deletes are notified to FakeWatcher.
• TestReaderWriter tracks assetsWritten.
• Support checks on reader state after a build action in resolveSources.

• Allow analyzer version 2.x.x.

• Migrate internal builders of this package to null safety
• Require build_config version 1.0.0.

• Migrate package:build_test/build_test.dart to null safety.
• Update to build 2.x.
• Update to build_resolvers 2.x.

• Use $package$ placeholder instead of $test$.

• Add support for running generated .browser_test.dart directly instead of expecting the test runner with the query string directRun=true. It is no longer necessary to create a build config which generates for *_test.dart files in build_web_compilers, the default config generates for .browser_test.dart files which are used by debug.html.

• Allow package:build versions through 1.5.x.

• Improve/fix testBuilder documentation.
• Update test bootstrap builder to copy language version comments from the test file if present.

• Add support for recognizing custom platforms in TestOn annotations during bootstrapping.

• Add support for enabling experiments via withEnabledExperiments zones from package:build, as well as forwarding the packageConfig argument from resolve* apis through to the default Resolver.
  • Note: If passing your own Resolver these things are still your responsibility.
• Added the ability to pass a PackageConfig to testBuilder, which is used to set the language version of each package.
  • The resolver created from testBuilder will also now respect the withEnabledExperiments zone.

• Removed dependency on package:package_resolver, changed to package:package_config.
  • All apis which used to take a PackageResolver now take a PackageConfig.
• Require SDK version 2.7.0.

• Allow the latest test_core package (0.3.x).

• Fix a bug with the resolve* apis where they would leak unhandled async errors to client code if the provided action callback threw an error.

• Add support for the new $package$ placeholder.

Potentially Breaking Change #

• Only add the non-lib placeholders when a root package is specified
  • Infer the root package when there is only one package in the sources
  • This is being released as a non-breaking change because the only expected use cases already would have been broken - findAssets calls already required a root package.

• Allow reading of assets written from the same build step.
  • This mirrors the latest behavior in build_runner_core.
• Require SDK version 2.6.0 to enable extension methods.

• Fix the DebugTestBuilder on windows.
• Fix PackageAssetReader on windows.

• Allow tracking of reported unused assets in testBuilder calls with the reportUnusedAssetsForInput(AssetId input, Iterable<AssetId> unused) callback.

• Allow a custom AssetReader to be passed to testBuilder. This will be used as a fallback for any sources that don't exist in the sourceAssets map.

• Handle the case where the root package in a PackageAssetReader is a fake package.

• Avoid throwing for missing files from PackageAssetReader.canRead.

• Allow build_config 0.4.x.

• Support the latest version of package:html.
• Only generate bootstrap scripts for supported platforms based on TestOn annotations.

• Allow build_resolvers version 1.0.0.

• Improve error messages for unresolvable URIs in the PackageAssetReader.

• Allow using PackageAssetReader when the current working directory is not the root package directory as long as it uses a pub layout.

• Increased the upper bound for package:analyzer to <0.35.0.

• Increased the upper bound for package:analyzer to '<0.34.0'.

• Declare support for package:build version 1.0.0.

• Increased the upper bound for the sdk to <3.0.0.

• Require test version ^0.12.42 and use TypeMatcher.
• Improve performance of test methods which use a Resolver by keeping a cached instance of AnalyzerResolvers.

• Allow the latest build_config.

• Remove package:build_barback dependency, and use public apis from package:test to directly do the bootstrapping instead of wrapping the transformer.

• Avoid looking for files from Uri.path paths.

• Add back an implementation of findAssets in PackageAssetReader.

• Added a DebugIndexBuilder, which by default generates a test/index.html with links to debug tests in your test/**_test.dart folder, linking to the generated *_test.debug.html files. NOTE: This only works for web-based tests.
• Fix PackageAssetReader when running with a package map pointing to a "packages" directory structure, as is generated by build_runner. Drop support for a broken findAssets implementation.

• Replace BarbackResolvers with AnalyzerResolvers from build_resolvers by default.

• Allow overriding the Resolvers used for resolve* utilities.
• Bug Fix: Don't call the action multiple times when there are multiple sources passed to resolve*.

• Added automatic generation of .debug.html files for all tests, which can be loaded in the browser to directly run tests and debug them without going through the package:test runner.
• Update to package:build version 0.12.0.
• Removed CopyBuilder in favor of TestBuilder which takes closures to change behavior rather than adding configuration for every possible modification.
• Added support for the special placeholder {$lib/$test/$web} assets supported by the build_runner and bazel_codegen implementations of package:build. For an example see test/test_builder_test.dart. Note that this is technically a BREAKING CHANGE, as additional inputs will be matched for overzealous builders (like TestBuilder).
• Added resolverFor as an optional parameter to resolveSources. By default a Resolver is returned for the first asset provided; to modify that the name of another asset may be provided. This is a BREAKING CHANGE, as previously the last asset was used.

• Added InMemoryAssetReader.shareAssetCache constructor. This is useful for the case where the reader should be kept up to date as assets are written through a writer.
• Added buildInputs stream to CopyBuilder which emits an event for each BuildStep.inputId at the top of the build method.
• CopyBuilder automatically skips the placeholder files (any file ending in $). This is technically breaking but should not affect any real users and is not being released as a breaking change.
• Changed TestBootstrapBuilder to only target _test.dart files.

• Added resolveSources, a way to resolve multiple libraries for testing, including any combination of fake files (in-memory, created in the test) and real ones (from on-disk packages):

test('multiple assets, some mock, some on disk', () async {
  final real = 'build_test|test/_files/example_lib.dart';
  final mock = 'build_test|test/_files/not_really_here.dart';
  final library = await resolveSources(
    {
      real: useAssetReader,
      mock: r'''
        // This is a fake library that we're mocking.
        library example;

        // This is a real on-disk library we are using.
        import 'example_lib.dart';

        class ExamplePrime extends Example {}
      ''',
    },
    (resolver) => resolver.findLibraryByName('example'),
  );
  final type = library.getType('ExamplePrime');
  expect(type, isNotNull);
  expect(type.supertype.name, 'Example');
});

• 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.
