Implementations

impl TestFiles

pub fn file(&self, path: &str, content: &str) -> &Self

Creates a plain file under temporary directory, with specified content.

Examples

use indoc::indoc;
use std::fs;

let temp_dir = test_files::TestFiles::new();
temp_dir.file("a/b/c.txt", indoc!{"
    ok
"})
.file("b/c/d.txt", indoc!{"
    fine
"});

let file_path = temp_dir.path().join("a").join("b").join("c.txt");
let written_content = fs::read_to_string(file_path).unwrap();
assert_eq!(written_content, "ok");

let file_path = temp_dir.path().join("b").join("c").join("d.txt");
let written_content = fs::read_to_string(file_path).unwrap();
assert_eq!(written_content, "fine");

pub fn new() -> Self

Creates a new temporary directory that is removed when it goes out of scope.

Panics on failure

Examples

let temp_dir = test_files::TestFiles::new();

assert!(temp_dir.path().is_dir());

pub fn path(&self) -> &Path

Returns the path of the underlying temporary directory.

Examples

let temp_dir = test_files::TestFiles::new();

assert!(temp_dir.path().is_dir());

pub fn try_file(&self, path: &str, content: &str) -> Result<&Self>

Tries to create a plain file under temporary directory with specified content.

Examples

use indoc::indoc;
use std::fs;

let temp_dir = test_files::TestFiles::new();
temp_dir.try_file("a/b/c.txt", indoc!{"
    ok
"})?
.try_file("b/c/d.txt", indoc!{"
    fine
"})?;

let file_path = temp_dir.path().join("a").join("b").join("c.txt");
let written_content = fs::read_to_string(file_path).unwrap();
assert_eq!(written_content, "ok");

let file_path = temp_dir.path().join("b").join("c").join("d.txt");
let written_content = fs::read_to_string(file_path).unwrap();
assert_eq!(written_content, "fine");

pub fn try_new() -> Result<Self>

Tries to create a new temporary directory that is removed when it goes out of scope.

Examples

let temp_dir = test_files::TestFiles::try_new();

assert!(temp_dir.is_ok());
assert!(temp_dir.unwrap().path().is_dir());
