testReader method

Future<List<PendingTest>> testReader (
  1. BuildContext context,
  2. {String suiteName}
)

Reads and returns zero or more tests from the assets defined by testAssets. This ignores the context that is passed in. This will never throw an error or return null and will instead return an empty array if it encounters issues loading the tests.

If the suiteName is not-null, this will exclude any tests that are not same test suite.

Implementation

Future<List<PendingTest>> testReader(
  BuildContext context, {
  String suiteName,
}) async {
  var files = <String>[];

  if (testAssetIndex?.isNotEmpty == true) {
    try {
      var indexData = await rootBundle.loadString(testAssetIndex);
      files = List<String>.from(json.decode(indexData));
    } catch (e, stack) {
      _logger.severe('Error in AssetTestStore.testReader', e, stack);
    }
  } else {
    files = testAssets;
  }

  var tests = <PendingTest>[];

  if (files?.isNotEmpty == true) {
    for (var asset in files) {
      try {
        var text = await rootBundle.loadString(asset);
        if (text?.isNotEmpty == true) {
          var parsed = json.decode(text);

          tests.addAll(TestStore.createMemoryTests(parsed));
        }
      } catch (e, stack) {
        _logger.severe('Error in AssetTestStore.testReader', e, stack);
      }
    }

    tests?.removeWhere(
      (test) => suiteName?.isNotEmpty == true && suiteName != test.suiteName,
    );
  }

  return tests ?? <PendingTest>[];
}
