create_temporary_directory()

auto arene::base::testing::filesystem::create_temporary_directory ( ) -> arene::base::filesystem::temporary_directory

inline

construct a temporary directory within the test runtime

Constructs a temporary directory with special handling when the test binary is invoked with Bazel.

When a test is run under Bazel, Bazel defines the environment variable TEST_TMPDIR. This is guaranteed by Bazel to be unique for each invocation of bazel test and the directory where tests should create files.

This function creates a temporary directory under a root path where:

• the root path is TEST_TMPDIR if it is defined;
• otherwise, the root path is TMPDIR if it is defined;
• otherwise, the default root path used by temporary_directory

Returns

the created temporary_directory value
