Nullean.Snapshots.Images.Assertions
AwesomeAssertions extensions for Nullean.Snapshots.Images: MatchImageSnapshot for PNG bytes and streams, compared by pixels with a diff image on failure.
Install
dotnet add package Nullean.Snapshots.Images.Assertions
Quick start
using AwesomeAssertions;
using Nullean.Snapshots.Images;
public class ChartTests
{
[Test]
public void Draws()
{
byte[] png = Chart.Render();
png.Should().MatchImageSnapshot(); // .verified.png, compared by pixels
png.Should().MatchImageSnapshot(new ImageSnapshotOptions { MaxDifferentRatio = 0.001 }, name: "tolerant");
}
}
On a mismatch the message gives the count, the share and the regions that differ, and points at the received image and its diff image, both in the received folder:
Image did not match snapshot: tests/App.Tests/.snapshots/ChartTests/Draws.verified.png
1,204 of 480,000 pixels differ (0.25%), 0 allowed; 36 anti-aliased pixel(s) left out
2 difference(s):
x 120-184, y 40-58 (65x19): 1,180 pixel(s)
x 610-613, y 402-405 (4x4): 24 pixel(s)
Received: .artifacts/.snapshots/received/App.Tests/ChartTests/Draws.received.png
