Prevent test folder deletion on running `flutter create --empty` on an existing app project #147160

victoreronmosele · 2024-04-22T13:04:41Z

This PR modifies the flutter create --empty command to not delete the test/ folder when run on an existing app project.

Before:

flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty  
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test does not exist

After:

flutter create my_app --empty
mkdir my_app/test
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists
flutter create my_app --empty  
if test -d my_app/test; then echo "test exists"; else echo "test does not exist"; fi # test exists

Fixes #134928

packages/flutter_tools/test/commands.shard/permeable/create_test.dart

+  testUsingContext('does not remove the test/ directory when recreating an application project with the --empty flag', () async {
+    await _createProject(
+      projectDir,
+      <String>['--no-pub', '--empty'],
+      <String>[],
+    );
+
+    projectDir.childDirectory('test').childFile('example_test.dart').createSync(recursive: true);
+
+    return _createProject(
+      projectDir,
+      <String>['--no-pub', '--empty'],
+      <String>['test/example_test.dart'],
+    );
+  });


It looks like this test is missing an assertion

_createProject implicitly asserts that test/example_test.dart exists but I agree with adding an explicit assertion too.

I will include it.

LGTM

When not creating a new project, won't this recreate test/widget_test.dart if it doesn't exist?

Ideally, this should probably just never write a file to test at all, and skip the delete step.

Indeed, this seems to be the case.

Ideally, this should probably just never write a file to test at all, and skip the delete step.

Agreed.

Agreed. Will make this change.

I've modified the create command so that when run with --empty, it doesn't write to the test/ directory, for either new or existing projects.

gspencergoog

Thanks!! This is much cleaner, and the tests are great.

gspencergoog · 2024-05-22T00:19:38Z

@andrewkolos Can you re-review this now that it's been updated?

andrewkolos

LGTM! Thanks for the continued work on this!
