Golden Diff

Easily compare golden failures and check the difference. A valuable tool to save you time in Flutter development and automated tests.

Features

This extension looks for images of golden test failures on your project, it makes a list with all the files reached. By clicking on one it's possible to see the difference between the expected image and the image that was generated by the golden toolkit.

Once there are test failures on your project, there will be a slider that reveals the expected image above the failure.

Let's see an example:

Imagine you've made some alterations, and suddenly, the tests begin to fail:

Test fails

Locate the failure in list

With the Golden Diff extension, pinpointing errors becomes effortless. Simply navigate to the extension to quickly identify failures, compare expected versus generated outcomes, and save valuable time troubleshooting.

Open the failure and see what happens

Compare the generated images

Here, you can explore the various types of golden tests available, offering insight into what's happening behind the scenes. Golden Diff consolidates this information, streamlining your workflow and saving you precious time:

Failure vs Expected

The Failure image will have a red shadow and the Expected image will show a green shadow to effort the difference.

Isolated image

The isolated mode will present any discrepancies found between the expected image and what was actually detected.

Master Image

The master image will showcase both the expected and failure images overlaid, making it effortless to discern the differences.

Find the test easily
