Method env

src/cmd.rs:318–325

Inserts or updates an environment variable mapping. Note that environment variable names are case-insensitive (but case-preserving) on Windows, and case-sensitive on all other platforms. # Examples Basic usage: ```no_run use assert_cmd::Command; Command::new("ls") .env("PATH", "/bin") .unwrap_err(); ```

(&mut self, key: K, val: V)

    ///         .unwrap_err();
    /// ```
    pub fn env<K, V>(&mut self, key: K, val: V) -> &mut Self
    where
        K: AsRef<ffi::OsStr>,
        V: AsRef<ffi::OsStr>,
    {
        self.cmd.env(key, val);
        self
    }

    /// Adds or updates multiple environment variable mappings.
