From 66dbd29cd194a4c84f796f32827429895c2a3bba Mon Sep 17 00:00:00 2001 From: Joe Wilm Date: Sat, 19 Nov 2016 16:16:20 -0800 Subject: Add support for recording/running ref tests 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`. --- src/renderer/mod.rs | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/renderer/mod.rs') diff --git a/src/renderer/mod.rs b/src/renderer/mod.rs index 333604f6..dfaf6b30 100644 --- a/src/renderer/mod.rs +++ b/src/renderer/mod.rs @@ -1100,6 +1100,7 @@ impl From for ShaderCreationError { /// /// The strategy for filling an atlas looks roughly like this: /// +/// ```ignore /// (width, height) /// ┌─────┬─────┬─────┬─────┬─────┐ /// │ 10 │ │ │ │ │ <- Empty spaces; can be filled while @@ -1112,6 +1113,7 @@ impl From for ShaderCreationError { /// │ │ │ │ │ <- Row considered full when next glyph doesn't /// └─────┴─────┴─────┴───────────┘ fit in the row. /// (0, 0) x-> +/// ``` #[derive(Debug)] struct Atlas { /// Texture id for this atlas -- cgit v1.2.3-54-g00ecf
