[macOS] Refactor the `flutter run` macOS console output test #114645

loic-sharma · 2022-11-03T22:10:51Z

The run_release_test_macos integration test verifies that that the console output of flutter run -d macos --release is expected. This change introduces a RunOutputTask abstraction so that the test's logic can be reused by other platforms like Android and Windows. This new RunOutputTask mirrors other existing device lab tasks like BuildTestTask and PerfTest.

In the future, we will:

Move the existing run_release_test Android integration test to RunOutputTask
Add a new flutter run console output integration test for Windows (see Test that flutter run doesn't introduce new debug spew #111577)
Consider adding flutter run console output tests for other platforms like iOS, Linux, web

Part of #111577

FYI I removed this logic to ignore standard output as it had no effect on the test. The _findNextMatcherInList helper used to verify console output can skip lines.

This may cause out-of-band failures when Xcode is updated, since Xcode loves to add debugging spew, and the macOS build output filtering is very manual:

flutter/packages/flutter_tools/lib/src/macos/build_macos.dart

Lines 22 to 28 in 850f3b3

/// When run in -quiet mode, Xcode should only print from the underlying tasks to stdout.

/// Passing this regexp to trace moves the stdout output to stderr.

///

/// Filter out xcodebuild logging unrelated to macOS builds:

/// xcodebuild[2096:1927385] Requested but did not find extension point with identifier Xcode.IDEKit.ExtensionPointIdentifierToBundleIdentifier for extension Xcode.DebuggerFoundation.AppExtensionToBundleIdentifierMap.watchOS of plug-in com.apple.dt.IDEWatchSupportCore

/// note: Using new build system

final RegExp _filteredOutput = RegExp(r'^((?!Requested but did not find extension point with identifier|note\:).)*$');

(as opposed to iOS where the tool output comes from parsing the Xcode build result, not from Xcode build stdout, would really really love macOS to adopt this)

flutter/packages/flutter_tools/lib/src/ios/mac.dart

Lines 406 to 409 in 8aad119

final XCResultIssueDiscarder warningDiscarder = XCResultIssueDiscarder(typeMatcher: XCResultIssueType.warning);

final XCResultIssueDiscarder dartBuildErrorDiscarder = XCResultIssueDiscarder(messageMatcher: RegExp(r'Command PhaseScriptExecution failed with a nonzero exit code'));

final XCResultGenerator xcResultGenerator = XCResultGenerator(resultPath: resultBundle.absolute.path, xcode: globals.xcode!, processUtils: globals.processUtils);

xcResult = await xcResultGenerator.generate(issueDiscarders: <XCResultIssueDiscarder>[warningDiscarder, dartBuildErrorDiscarder]);

Either we can make this more flexible and accept any upcoming line, or we can accept that additional filters may need to be applied as part of updating Xcode.

I don't think this is a problem as this test ignores unmatched lines. It only checks that the expected lines are in standard output in the correct order. Any Xcode log spew on standard output would be ignored by this test.

Please let me know if I misunderstood your concern!

Nah I just have Friday brain, your logic LGTM.
