| //! Helper for writing test cases. |
| //! |
| //! Create a TempTestEnv to provide some lite isolation in the way of a |
| //! temporary HOME, PATH env settings, etc.. These will be removed/restored when |
| //! the temp env is dropped. |
| //! |
| //! It's strongly advised to use with some form of test serialization such as |
| //! the serialize_test crate. The env is global to the process, so running tests |
| //! with env changes in parallel will be confusing. |
| //! |
| //! ``` |
| //! #[cfg(test)] |
| //! mod tests { |
| //! use {super::*, temp_test_env::TempTestEnv, serial_test::serial}; |
| //! |
| //! #[test] |
| //! #[serial] |
| //! fn test_something() { |
| //! let test_env = TempTestEnv::new()?; |
| //! [...] |
| //! } |
| //! } |
| //! ``` |
