Module assertables::assert_command

Assert macros for comparing commands and their stdout & stderr.

These macros help with calling external commands, then capturing the standard output stream and standard error stream.

These macros have corresponding the macros in the module assert_program_args.

Compare command standard output string:

• assert_command_stdout_eq!(command1, command2) ≈ command1 stdout = command2 stdout

• assert_command_stdout_eq_expr!(command, expr) ≈ command stdout = expr

• assert_command_stdout_contains!(command, containee) ≈ command stdout contains containee

• assert_command_stdout_is_match!(command, matcher) ≈ command stdout is a matcher match

Compare command standard error string:

• assert_command_stderr_eq!(command1, command2) ≈ command1 stderr = command2 stderr

• assert_command_stderr_eq_expr!(command, expr) ≈ command stderr = expr

• assert_command_stderr_contains!(command, containee) ≈ command stderr contains containee

• assert_command_stderr_is_match!(command, matcher) ≈ command stderr is a matcher match

Example

use std::process::Command;

let mut a = Command::new("bin/printf-stdout");
a.args(["%s", "hello"]);
let mut b = Command::new("bin/printf-stdout");
b.args(["%s%s%s%s%s", "h", "e", "l", "l", "o"]);
assert_command_stdout_eq!(a, b);
