From 713efcc2f4764fd7c2a6ad539c45124e60f43656 Mon Sep 17 00:00:00 2001 From: Tig Date: Sat, 22 Nov 2025 21:29:44 -0700 Subject: [PATCH] WIP: Fixed Parallel tests; non-Parallel still broken Refactor application model usage tracking Refactored `ApplicationModelUsage` into a public enum in the new `Terminal.Gui.App` namespace, making it accessible across the codebase. Replaced the private `_modelUsage` field in `ApplicationImpl` with a public static `ModelUsage` property to improve clarity and accessibility. Renamed error message constants for consistency and updated methods like `SetInstance` and `MarkInstanceBasedModelUsed` to use the new `ModelUsage` property. Removed the private `ApplicationModelUsage` enum from `ApplicationImpl`. Updated test cases to use `ApplicationImpl.Instance` instead of `Application.Create` to enforce the legacy static model. Skipped obsolete tests in `ApplicationForceDriverTests` and added null checks in `DriverAssert` and `SelectorBase` to handle edge cases. Commented out an unused line in `WindowsOutput` and made general improvements to code readability, maintainability, and consistency. --- Terminal.Gui/App/Application.Navigation.cs | 1 - Terminal.Gui/App/ApplicationImpl.Lifecycle.cs | 8 ++-- Terminal.Gui/App/ApplicationImpl.cs | 42 +++++++------------ Terminal.Gui/App/ApplicationModelUsage.cs | 16 +++++++ .../Drivers/FakeDriver/FakeInputProcessor.cs | 2 +- .../Drivers/WindowsDriver/WindowsOutput.cs | 2 +- Terminal.Gui/Views/Selectors/SelectorBase.cs | 2 +- .../Application.NavigationTests.cs | 4 +- .../ApplicationForceDriverTests.cs | 6 +-- .../ApplicationImplBeginEndTests.cs | 2 +- .../ApplicationModelFencingTests.cs | 6 +-- .../UnitTests/Application/ApplicationTests.cs | 2 +- Tests/UnitTests/DriverAssert.cs | 28 +++++++++---- .../View/Navigation/CanFocusTests.cs | 2 +- 14 files changed, 71 insertions(+), 52 deletions(-) create mode 100644 Terminal.Gui/App/ApplicationModelUsage.cs diff --git a/Terminal.Gui/App/Application.Navigation.cs b/Terminal.Gui/App/Application.Navigation.cs index 673a76420..031ebac1c 100644 --- a/Terminal.Gui/App/Application.Navigation.cs +++ b/Terminal.Gui/App/Application.Navigation.cs @@ -17,7 +17,6 @@ public static partial class Application // Navigation stuff /// Alternative key to navigate forwards through views.
