 """A Windows-only end-to-end integration test for Kasko, Chrome and Crashpad.
 
 This test ensures that the interface between Kasko and Chrome and Crashpad works
 as expected. The test causes Kasko to set certain crash keys and invoke a crash
 report, which is in turn delivered to a locally hosted test crash server. If the
 crash report is received intact with the expected crash keys then all is well.
 
 Note that this test only works against non-component Release and Official builds
 of Chrome with Chrome branding, and attempting to use it with anything else will
 most likely lead to constant failures.
 
 Typical usage (assuming in root 'src' directory):
 
 - generate project files with the following GYP variables:
     branding=Chrome syzyasan=1 win_z7=0 chromium_win_pch=0
-- build the release Chrome binaries:
+- build the release Chrome binaries and driver:
     ninja -C out\Release chrome.exe
+    ninja -C out\Release chromedriver.exe
 - run the test:
-    python chrome/test/kasko/kasko_integration_test.py --chrome-dir=out/Release
+    python chrome/test/kasko/kasko_integration_test.py
 
 Many of the components in this test could be reused in other end-to-end crash
 testing. Feel free to open them up for reuse, but please CC chrisha@chromium.org
 on any associated reviews or bugs!
