This page can be used to smoke test the screen reader usage with VS Code. In the following always have screen reader accessibility mode toggled on.

• For macOS use VoiceOver. The gold standard is XCode.
• For windows use NVDA. The golden standard is Visual Studio.

In the following tests use the following example code:

export interface IRange {	start: number;	end: number; } export interface IRangedGroup {	range: IRange;	size: number; } export namespace Range {	/** * Returns the intersection between two ranges as a range itself. * Returns `{ start: 0, end: 0 }` if the intersection is empty. */	export function intersect(one: IRange, other: IRange): IRange {	if (one.start >= other.end || other.start >= one.end) {	return { start: 0, end: 0 };	}	const start = Math.max(one.start, other.start);	const end = Math.min(one.end, other.end);	if (end - start <= 0) {	return { start: 0, end: 0 };	}	return { start, end };	}	export function isEmpty(range: IRange): boolean {	return range.end - range.start <= 0;	}	export function intersects(one: IRange, other: IRange): boolean {	return !isEmpty(intersect(one, other));	}	export function relativeComplement(one: IRange, other: IRange): IRange[] {	const result: IRange[] = [];	const first = { start: one.start, end: Math.min(other.start, one.end) };	const second = { start: Math.max(other.end, one.start), end: one.end };	if (!isEmpty(first)) {	result.push(first);	}	if (!isEmpty(second)) {	result.push(second);	}	return result;	} } 

• Place the cursor on (1, 1). Move cursor down, move cursor up.
• Verify the screen reader reads the full first line.

macOS:

• Verify there is a black box surrounding the line that is read
• Move cursor right to (1, 2) with the right arrow. Verify it reads e.
• Move cursor right to (1, 3) with the right arrow. Verify it reads x.

windows:

• Verify there is a black box surrounding the line that is read
• Move cursor right to (1, 2) with the right arrow. Verify it reads x.
• Move cursor right to (1, 3) with the right arrow. Verify it reads p.

• Set the setting editor.wordWrapColumn to 10
• Set the setting editor.wordWrap to wordWrapColumn
• Place the cursor on (1, 1).
• Put cursor down once, verify it reads: interface
• Put cursor down once, verify it reads: IRange {

macos:

• Consider the keybindings:
  • Option + leftArrow to read the previous word
  • Option + rightArrow to read the next word
• Place the cursor on (1, 1)
• Jump to the next word. The screen reader should read export
• Jump to the next word. The screen reader should read interface
• Jump to the previous word. The screen reader should read export

windows:

• Consider the keybindings:
  • NVDA + ctrl + leftArrow to read the previous word
  • NVDA + ctrl + rightArrow to read the next word
• Place the cursor on (1, 1)
• Jump to the next word. The screen reader should read interface
• Jump to the previous word. The screen reader should read export
