As mentioned at https://chromium-review.googlesource.com/c/chromium/src/+/735820#message-e8b199498d8b850f2612c46648069d819dd47517, the typical Windows behavior for symbolic links requires administrative privileges. Symbolic links are available to non-administrators in Windows 10.0.15063 and later (1703, Creators Update), provided that developer mode has been enabled and SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE is passed to CreateSymbolicLink(). See https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/. This adds SYMBOLIC_LINK_FLAG_ALLOW_UNPRIVILEGED_CREATE to uses of CreateSymbolicLink(), and creates test::CanCreateSymbolicLinks() to determine whether symbolic link creation is possible. Tests that exercise symbolic links are adapted to gate all symbolic link operations on this test.

//! gtest only provides a mechanism for tests to be disabled statically, by

//! necessary to disable tests dynamically, gtest provides no assistance. This
|

//! environment tear-down before the test executable exits.
|

//!
|
||
//! This macro may only be invoked from the context of a gtest test.

//! href="https://groups.google.com/d/topic/googletestframework/Nwh3u7YFuN4">gtest
|
||
//! feature request</a> to provide this functionality directly in gtest, but

//! since it hasn’t been implemented, this macro provides a local mechanism to
|
