Module assert_command

Assert 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.

Command standard output

Compare command standard output to another command standard output:

• assert_command_stdout_eq2!(command1, command2) ≈ command1 stdout = command2 stdout
• assert_command_stdout_ne2!(command1, command2) ≈ command1 stdout ≠ command2 stdout
• assert_command_stdout_lt2!(command1, command2) ≈ command1 stdout < command2 stdout
• assert_command_stdout_le2!(command1, command2) ≈ command1 stdout ≤ command2 stdout
• assert_command_stdout_gt2!(command1, command2) ≈ command1 stdout > command2 stdout
• assert_command_stdout_ge2!(command1, command2) ≈ command1 stdout ≥ command2 stdout

Compare command standard output to an expression:

• assert_command_stdout_eq!(command, expr) ≈ command stdout = expr
• assert_command_stdout_ne!(command, expr) ≈ command stdout ≠ expr
• assert_command_stdout_lt!(command, expr) ≈ command stdout < expr
• assert_command_stdout_le!(command, expr) ≈ command stdout ≤ expr
• assert_command_stdout_gt!(command, expr) ≈ command stdout > expr
• assert_command_stdout_ge!(command, expr) ≈ command stdout ≥ expr

Assert command standard output as a string:

• assert_command_stdout_string_contains!(command, containee) ≈ command stdout string contains containee
• assert_command_stdout_string_is_match!(command, matcher) ≈ command stdout string is a matcher match

Command standard error

Compare command standard error to another command standard error:

• assert_command_stderr_eq2!(command1, command2) ≈ command1 stderr = command2 stderr
• assert_command_stderr_ne2!(command1, command2) ≈ command1 stderr ≠ command2 stderr
• assert_command_stderr_lt2!(command1, command2) ≈ command1 stderr < command2 stderr
• assert_command_stderr_le2!(command1, command2) ≈ command1 stderr ≤ command2 stderr
• assert_command_stderr_gt2!(command1, command2) ≈ command1 stderr > command2 stderr
• assert_command_stderr_ge2!(command1, command2) ≈ command1 stderr ≥ command2 stderr

Compare command standard error to an expression:

• assert_command_stderr_eq!(command, expr) ≈ command stderr = expr
• assert_command_stderr_ne!(command, expr) ≈ command stderr ≠ expr
• assert_command_stderr_lt!(command, expr) ≈ command stderr < expr
• assert_command_stderr_le!(command, expr) ≈ command stderr ≤ expr
• assert_command_stderr_gt!(command, expr) ≈ command stderr > expr
• assert_command_stderr_ge!(command, expr) ≈ command stderr ≥ expr

Assert standard error as a string:

• assert_command_stderr_string_contains!(command, containee) ≈ command stderr string contains containee
• assert_command_stderr_string_is_match!(command, matcher) ≈ command stderr string is a matcher match

Example

use assertables::*;
use std::process::Command;

let mut a = Command::new("bin/printf-stdout");
a.args(["%s", "alfa"]);
let mut b = Command::new("bin/printf-stdout");
b.args(["%s%s%s%s", "a", "l", "f", "a"]);
assert_command_stdout_eq2!(a, b);
