LESSON 11 OF 20
NVDA
NVDA is a free, open-source Windows screen reader. It is especially useful for routine desktop web testing because teams can install it, learn a small command set, and compare browser behaviour in a repeatable way.
This reference assumes that you have completed the foundation course and understand names, roles, states, focus, and dynamic updates.
Choose an environment
What NVDA testing depends on
Browse mode
NVDA presents web pages and other structured documents through browse mode, where cursor keys and single-letter commands move through the document.
Focus mode
When a user interacts with form fields, widgets, and application controls, NVDA may switch to focus mode so keys are passed to the browser or application.
Browser combinations
NVDA results can differ between Chrome, Firefox, Edge, and embedded browser contexts because the browser and screen reader both interpret exposed accessibility information.
Keyboard layout and settings
Desktop or laptop keyboard layout, selected NVDA modifier keys, speech settings, add-ons, and browser versions should be recorded before interpreting defects.
One reader, several web-testing contexts
| Environment | Primary input | What shapes the experience |
|---|---|---|
| Windows | Keyboard | Desktop web apps, browser documents, forms, browse mode, focus mode, headings, landmarks, and tables |
TRY THIS NOW
Separate reading from interaction
Choose one Windows web task and mark which parts are tested in browse mode and which require focus mode.
- StructureUse headings, landmarks, links, and form-field movement to discover the page.
- InteractionEnter fields, operate controls, and confirm when focus mode is involved.
- BrowserRecord whether the task uses Chrome, Firefox, Edge, or another embedded browser context.
- EvidenceDescribe focus, speech output, exposed structure, task result, and impact separately.
What product teams should take from this
- NVDA with Chrome or Firefox is a practical baseline for Windows desktop web testing.
- A passing NVDA result does not represent JAWS, Narrator, VoiceOver, TalkBack, or every browser engine.
- Test browse-mode reading, focus-mode interaction, form recovery, headings, landmarks, tables, and dynamic updates in the same representative task.
- User observations will be added after credited research with regular users; they are not inferred from documentation.
