Instance Method Summary

• #assert_buffer_lines(buffer : UI::Buffer, expected : Array(String), trim_trailing : Bool = true, file = __FILE__, line = __LINE__) : Nil

  Asserts that the 2D buffer's rendered character grid matches the expected lines.

• #assert_cell(buffer : UI::Buffer, x : Int32, y : Int32, char : Char | Nil = nil, fg : Color | Nil = nil, bg : Color | Nil = nil, bold : Bool | Nil = nil, underline : Bool | Nil = nil, dim : Bool | Nil = nil, italic : Bool | Nil = nil, file = __FILE__, line = __LINE__) : Nil

  Asserts a single cell's exact character and style properties at (x, y).

• #buffer_lines(buffer : UI::Buffer, trim_trailing : Bool = true) : Array(String)

  Extracts the text lines from a buffer.

• #driver_lines(driver : Terminal::MockDriver, trim_trailing : Bool = true) : Array(String)

  Extracts the text lines from a mock driver by inspecting its stripped output or frame.
