2. Place your test data in testbed directory as urls.txt The grammar of urls.txt is as follows:

file = (URL , expected? | options)*

URL: URL to be tested.

expected (optional): expected result of FindProxyForURL(url, host) function.

options: -date yyyy-mm-dd -time hh:mm[:ss] -timezone timezone -myIpAddress address -hosts (name address ...)

2 Running it by Gradle

1. Arrange ext { ... } section of build.gradle
2. Run as in follows:

gradle run [>report.txt]
