Ref tests use a recording of the terminal protocol and a serialization of the grid state to check that the parsing and action handling systems produce the correct result. Ref tests may be recorded by running alacritty with `--ref-test` and closing the terminal by using the window "X" button. At that point, the recording is fully written to disk, and a serialization of important state is recorded. Those files should be moved to an appropriate folder in the `tests/ref/` tree, and the `ref_test!` macro invocation should be updated accordingly. A couple of changes were necessary to make this work: * Ref tests shouldn't create a pty; the pty was refactored out of the `Term` type. * Repeatable lines/cols were needed; on startup, the terminal is resized * by default to 80x24 though that may be changed by passing `--dimensions w h`. * Calculating window size based on desired rows/columns and font metrics required making load_font callable multiple times. * Refactor types into library crate so they may be imported in an integration test. * A whole bunch of types needed symmetric serialization and deserialization. Mostly this was just adding derives, but the custom deserialization of Rgb had to change to a deserialize_with function. This initially adds one ref test as a sanity check, and more will be added in subsequent commits. This initial ref tests just starts the terminal and runs `ll`. |
