Metamorphic testing is a powerful technique that provides additional test coverage by applying a number of transformations to test input, and then checking if certain relations still hold between the outputs. Marble will automatically run through all possible combinations of these transformations.
Metamorphic testing does not aspire to replace oracle based input/output testing, but should rather be viewed as a new gadget in the toolbox. While it requires some creativity and effort to come up with a good metamorphic test, you might be rewarded with the uncovering of issues that would otherwise go unnoticed. This applies not only to correctness tests, but also non-functional tests such as performance.
Here's a [great introduction by](https://www.cockroachlabs.com/blog/metamorphic-testing-the-database/) Cockroach Labs. I highly recommend reading before using this library.
The repository contains a few [test examples](https://github.com/cryptocode/marble/blob/main/src/example_tests.zig)
