I think these are some good resources:

Unit Testing in Motoko

Motoko: How to write unit tests?

We are still experimenting with the best way to test Motoko and canisters. There are several tools around today that can help with unit testing: Built-in assert: see examples from the base library: motoko-base/test at master · dfinity/motoko-base · GitHub The Motoko matcher library: GitHub - kritzcreek/motoko-matchers. It’s best to test with library code, i.e. without service actors. ic-repl: GitHub - chenyan2002/ic-repl. This is designed at the canister level, so that you can use the tool to…

Motoko: How to write unit tests?

In addition to the approaches listed by @chenyan above, there is also the approach to use the ic-hs IC simulator as a library, and use Haskell to script the testing of the compiled canister. As it works with the compiled wasm, it works with both Motoko and Rust canisters. This is the approach chosen by the Internet Identity project:
