package:test should not depend on Dart SDK internals #2210
Description
Currently package:test seems to depend on an internal location and name of an AOT-compiled snapshot of e.g. dart2wasm compiler, see pkgs/test_core/lib/src/runner/wasm_compiler_pool.dart:
var platformDill =
p.join(sdkRoot, 'lib', '_internal', 'dart2wasm_platform.dill');
var dartPrecompiledRuntimePath = p.join(sdkRoot, 'bin', 'dartaotruntime');
var dart2wasmSnapshotPath =
p.join(sdkRoot, 'bin/snapshots', 'dart2wasm_product.snapshot');
var process = await Process.start(dartPrecompiledRuntimePath, [
dart2wasmSnapshotPath,
'--dart-sdk=$sdkRoot',
'--platform=$platformDill',
'--packages=${(await packageConfigUri).path}',
for (var experiment in enabledExperiments)
'--enable-experiment=$experiment',
wrapperPath,
outWasmPath,
]);3rd parties should not depend on <dart-sdk>/lib/_internal/* or <dart-sdk/bin/snapshots/*.
Why can package:test not use dart compile wasm instead?
