Assert
process::Command
- Easy command initialization and assertions.
assert_cmd
aims to simplify the process for doing integration testing of CLIs, including:
- Finding your crate's binary to test
- Assert on the result of your program's run.
Add to your Cargo.toml
:
[dependencies]
assert_cmd = "0.12.1"
Here's a trivial example:
use assert_cmd::Command;
let mut cmd = Command::cargo_bin("bin_fixture").unwrap();
cmd.assert().success();
See the docs for more.
Other crates that might be useful in testing command line programs.
- escargot for more control over configurin the crate's binary.
- duct for orchestrating multiple processes.
- or commandspec for easier writing of commands
- rexpect for testing interactive programs.
assert_fs
for filesystem fixtures and assertions.- or tempfile for scratchpad directories.
- dir-diff for testing file side-effects.
