Methods

compare(Uint8List imageBytes, Uri golden) → Future<bool>
Copy of LocalFileComparator's compare method, except for the fact that it checks if the ComparisonResult.diffPercent is not greater than threshold to decide whether this test is successful or a failure.
override
d(String message) → void
Logs a debug message
inherited
e(String message, [Object? error, StackTrace? stackTrace]) → void
Logs an error message
inherited
generateFailureOutput(ComparisonResult result, Uri golden, Uri basedir, {String key = ''}) → Future<String>
Writes out diffs from the ComparisonResult of a golden file test.
inherited
getFailureFile(String failure, Uri golden, Uri basedir) → File
Returns the appropriate file for a given diff from a ComparisonResult.
inherited
getGoldenBytes(Uri golden) → Future<List<int>>
Returns the bytes of the given golden file.
inherited
getTestUri(Uri key, int? version) → Uri
Returns a new golden file Uri to incorporate any version number with the key.
inherited
i(String message) → void
Logs an info message
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
update(Uri golden, Uint8List imageBytes) → Future<void>
Updates the golden file identified by golden with imageBytes.
inherited
w(String message) → void
