# CMP0064

Added in version 3.4.

Recognize `TEST` as a operator for the `if()` command.

The `TEST` operator was added to the `if()` command to determine if a given test name was created by the `add_test()` command.

The `OLD` behavior for this policy is to ignore the `TEST` operator. The `NEW` behavior is to interpret the `TEST` operator.

This policy was introduced in CMake version 3.4. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, and uses `OLD` behavior.

Note

The `OLD` behavior of a policy is `deprecated by definition` and may be removed in a future version of CMake.
