[−][src]Struct cli_test_dir::TestDir
This code is inspired by the WorkDir
pattern that BurntSushi uses to
test CLI tools like ripgrep
and xsv
.
Methods
impl TestDir
[src]
pub fn new(bin_name: &str, test_name: &str) -> TestDir
[src]
Create a new TestDir
for the current test. You must specify
bin_name
(the name of a binary built by the current crate) and
test_name
(a unique name for the current test).
If our output directory exists from a previous test run, it will be deleted.
pub fn cmd(&self) -> Command
[src]
Return a std::process::Command
object that can be used to execute
the binary.
pub fn path<P: AsRef<Path>>(&self, path: P) -> PathBuf
[src]
Construct a path relative to our test directory.
let testdir = TestDir::new("touch", "path_builds_paths"); let mut cmd = testdir.cmd(); cmd .arg("example.txt") .expect_success(); assert!(testdir.path("example.txt").exists());
pub fn src_path<P: AsRef<Path>>(&self, path: P) -> PathBuf
[src]
Return a path relative to the source directory of the current crate. Useful for finding fixtures.
pub fn create_file<P, S>(&self, path: P, contents: S) where
P: AsRef<Path>,
S: AsRef<[u8]>,
[src]
P: AsRef<Path>,
S: AsRef<[u8]>,
Create a file in our test directory with the specified contents.
pub fn expect_path<P: AsRef<Path>>(&self, path: P)
[src]
If path
does not point to valid path, fail the current test.
pub fn expect_no_such_path<P: AsRef<Path>>(&self, path: P)
[src]
If path
does not point to valid path, fail the current test.
pub fn expect_file_contents<P, S>(&self, path: P, expected: S) where
P: AsRef<Path>,
S: AsRef<[u8]>,
[src]
P: AsRef<Path>,
S: AsRef<[u8]>,
Verify that the file contains the specified data.
pub fn expect_contains<P>(&self, path: P, pattern: &str) where
P: AsRef<Path>,
[src]
P: AsRef<Path>,
Verify that the contents of the file match the specified pattern.
Someday this should support std::str::pattern::Pattern
so that we
can support both strings and regular expressions, but that hasn't
been stabilized yet.
pub fn expect_does_not_contain<P>(&self, path: P, pattern: &str) where
P: AsRef<Path>,
[src]
P: AsRef<Path>,
Verify that the contents of the file do not match the specified pattern.
Someday this should support std::str::pattern::Pattern
so that we can
support both strings and regular expressions, but that hasn't been
stabilized yet.
