Snapshooter is a flexible .Net testing tool, which can be used to validate all your test results with one single assert. It creates simply a snapshot of your test result object and stores it on the file system. If the test is executed again, the test result will be compared with the stored snapshot. If the snapshot matches to the test result, the test will pass.
The Snapshooter snapshot testing is based on the concept of Jest Snapshot Testing.
Supported Test Frameworks
The Snapshooter snapshot testing is available for the following .Net Test Frameworks:
- NUnit (coming soon)
- MsTest (coming soon)
To get started in a few minutes, we have prepared an example with xUnit, which explains you the most important steps and shows you how to handle the snapshots.
To understand the basic concept and idea of the snapshot testing, go to the Basic Concepts. It also explains where and in which format the snapshots are stored on the file system.
On Github we have prepared some common examples, which you can use as a template or as best practices for also more complex snapshot test cases.
