Struct cli_test_dir::TestDir
source · pub struct TestDir { /* private fields */ }
Expand description
This code is inspired by the WorkDir
pattern that BurntSushi uses to
test CLI tools like ripgrep
and xsv
.
Implementations§
source§impl TestDir
impl TestDir
sourcepub fn new(bin_name: &str, test_name: &str) -> TestDir
pub fn new(bin_name: &str, test_name: &str) -> TestDir
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.
sourcepub fn cmd(&self) -> Command
pub fn cmd(&self) -> Command
Return a std::process::Command
object that can be used to execute
the binary.
sourcepub fn path<P: AsRef<Path>>(&self, path: P) -> PathBuf
pub fn path<P: AsRef<Path>>(&self, path: P) -> PathBuf
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());
sourcepub fn src_path<P: AsRef<Path>>(&self, path: P) -> PathBuf
pub fn src_path<P: AsRef<Path>>(&self, path: P) -> PathBuf
Return a path relative to the source directory of the current crate. Useful for finding fixtures.
sourcepub fn create_file<P, S>(&self, path: P, contents: S)
pub fn create_file<P, S>(&self, path: P, contents: S)
Create a file in our test directory with the specified contents.
sourcepub fn expect_path<P: AsRef<Path>>(&self, path: P)
pub fn expect_path<P: AsRef<Path>>(&self, path: P)
If path
does not point to valid path, fail the current test.
sourcepub fn expect_no_such_path<P: AsRef<Path>>(&self, path: P)
pub fn expect_no_such_path<P: AsRef<Path>>(&self, path: P)
If path
does not point to valid path, fail the current test.
sourcepub fn expect_file_contents<P, S>(&self, path: P, expected: S)
pub fn expect_file_contents<P, S>(&self, path: P, expected: S)
Verify that the file contains the specified data.
sourcepub fn expect_contains<P>(&self, path: P, pattern: &str)
pub fn expect_contains<P>(&self, path: P, pattern: &str)
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.
sourcepub fn expect_does_not_contain<P>(&self, path: P, pattern: &str)
pub fn expect_does_not_contain<P>(&self, path: P, pattern: &str)
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.
