# Description Adds a `nu-plugin-test-support` crate with an interface that supports testing plugins. Unlike in reality, these plugins run in the same process on separate threads. This will allow testing aspects of the plugin internal state and handling serialized plugin custom values easily. We still serialize their custom values and all of the engine to plugin logic is still in play, so from a logical perspective this should still expose any bugs that would have been caused by that. The only difference is that it doesn't run in a different process, and doesn't try to serialize everything to the final wire format for stdin/stdout. TODO still: - [x] Clean up warnings about private types exposed in trait definition - [x] Automatically deserialize plugin custom values in the result so they can be inspected - [x] Automatic plugin examples test function - [x] Write a bit more documentation - [x] More tests - [x] Add MIT License file to new crate # User-Facing Changes Plugin developers get a nice way to test their plugins. # Tests + Formatting Run the tests with `cargo test -p nu-plugin-test-support -- --show-output` to see some examples of what the failing test output for examples can look like. I used the `difference` crate (MIT licensed) to make it look nice. - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] Add a section to the book about testing - [ ] Test some of the example plugins this way - [ ] Add example tests to nu_plugin_template so plugin developers have something to start with |

Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
