 """A Windows-only end-to-end integration test for Kasko and SyzyAsan.
 
 This test ensures that the interface between SyzyAsan, Kasko and Chrome works
 as expected. The test causes a crash that should be detected by SyzyAsan and
 delivered via Kasko to a locally hosted test crash server.
 
 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:
     syzyasan=1 win_z7=0 chromium_win_pch=0
 - build the release Chrome binaries:
-    ninja -C out\Release chrome.exe
+    ninja -C out\Release chrome.exe chromedriver.exe
 - run the test:
     python chrome/test/kasko/syzyasan_integration_test.py
