Usage:
|
|
node bisect.js --good <revision> --bad <revision> <script>
|
|
|
|
Parameters:
|
|
--good revision that is known to be GOOD, defaults to the chromium revision in src/revision.ts in the main branch
|
|
--bad revision that is known to be BAD, defaults to the chromium revision in src/revision.ts
|
|
--no-cache do not keep downloaded Chromium revisions
|
|
--unit-test pattern that identifies a unit tests that should be checked
|
|
--script path to a script that returns non-zero code for BAD revisions and 0 for good
|
|
|
|
Example:
|
|
node utils/bisect.js --unit-test test
|
|
node utils/bisect.js --good 577361 --bad 599821 --script simple.js
|
|
node utils/bisect.js --good 577361 --bad 599821 --unit-test test
