Move android_obfuscate_test from devicelab into tools integration.shard #169798

jmagman · 2025-05-30T23:12:41Z

android_obfuscate_test is currently being schedule to run on a limited devicelab physical phone bot. However, it's only checking if --obfuscate works, not running anything on the device, so can move into the tools test integration shard.

https://ci.chromium.org/ui/p/flutter/builders/prod/Linux_pixel_7pro%20android_obfuscate_test/7722/overview

The test only takes < 2 minutes, spinning up an entire build for it, especially on a devicelab bot, is wasteful.

Similar to #80161

A better version of

Lines 278 to 298 in 11bf180

testWithoutContext('validate obfuscation', () {

// Not present in binary.

outputAppFrameworkBinary.path,

]);

// Does not match exits 1.

expect(grepResult.exitCode, 1);

});

});

Inspired by

Lines 61 to 65 in 11bf180

final Archive archive = ZipDecoder().decodeBytes(outputFile.readAsBytesSync());

+      'build',
+      'apk',
+      '--target-platform=android-arm',
+      '--obfuscate',


I confirmed both of these tests fail with --no-obfuscate passed instead.

 Future<void> main() async {

+  // TODO(jmagman): Remove this file once the infra repo no longer contains "Linux_pixel_7pro android_obfuscate_test".


I'm unsure if this extra step is necessary, or I can remove this file in the same PR.

Moving this to a draft, @gmackall was working in here and I need to fix merge conflicts.

Was conflicted with #171165 adding stack traces to devicelab tests, which we won't need any more when it's moved to the integration test.
