runAppTests function

Future<(int, String)> runAppTests(GeneratedApp generated, MatrixApp app, List<MatrixAppTest> tests, { MatrixFlutter flutter = _flutter, FileSystem fileSystem = const LocalFileSystem(), })

Adds tests to generated, the app of the matrix app, with addAppTests, and runs the appTestCommands with flutter until one fails; returns its exit code and the output up to it, which says which command failed, or 0 and the output of all. A problem of the files of the tests is a failure too, with the exit code 1.

Implementation

Future<(int, String)> runAppTests(
  GeneratedApp generated,
  MatrixApp app,
  List<MatrixAppTest> tests, {
  MatrixFlutter flutter = _flutter,
  FileSystem fileSystem = const LocalFileSystem(),
}) async {
  final List<String> added;
  try {
    added = addAppTests(
      tests,
      app: app,
      directory: generated.path,
      packageName: generated.name,
      fileSystem: fileSystem,
    );
  } on MatrixAppTestException catch (error) {
    return (1, error.message);
  }
  final output = StringBuffer('Added the tests ${added.join(', ')}.\n');
  for (final arguments in appTestCommands(tests)) {
    final (code, text) = await flutter(arguments, generated.path);
    output.write(text);
    if (code != 0) {
      output.write('\nflutter ${arguments.join(' ')} exited with $code.');
      return (code, '$output');
    }
  }
  return (0, '$output');
}
