 """Semi-automated tests of Chrome with NVDA.
 
 This file performs (semi) automated tests of Chrome with NVDA
 (NonVisual Desktop Access), a popular open-source screen reader for
 visually impaired users on Windows. It works by launching Chrome in a
 subprocess, then launching NVDA in a special environment that simulates
 speech rather than actually speaking, and ignores all events coming from
 processes other than a specific Chrome process ID. Each test automates
 Chrome with a series of actions and asserts that NVDA gives the expected
 feedback in response.
 
 The tests are "semi" automated in the sense that they are not intended to be
 run from any developer machine, or on a buildbot - it requires setting up the
 environment according to the instructions in README.txt, then running the
 test script, then filing bugs for any potential failures. If the environment
 is set up correctly, the actual tests should run automatically and unattended.

I can't find the winapi module. Did you mean win32api?

I can't find the focusWindow function in win32api, where is it defined?

You'll need an editable text field here for this to work.
