Macro init_test_suite 

macro_rules! init_test_suite {
    ($test_suite:ident) => { ... };
    ($test_suite:ident, $($test_name:expr),*) => { ... };
}

The test suite initializer that constructs test suits based on the provided name (first parameter) and the provided functions (the comma-delimited list afterwards). Every function that is provided is expected only to return type ExtelResult, and should have no parameters.

These tests are stateless in nature, relying on their environment and hard-coded CLI args to handle configuration and valid setup.

Example

use std::process::Command;
use extel::prelude::*;

/// Run end-to-end test of application.
fn echo_no_arg_e2e() -> ExtelResult {
    match Command::new("echo").status() {
        Ok(exit_code) => {
            let code: i32 = exit_code.code().unwrap_or(-1);
            extel_assert!(code == 0, "failed with exit code: {}", code)
        },
        Err(msg) => {
            fail!("failed to execute with error: {}", msg)
        }
    }
}

// Outputs:
//  Test #1 (echo_no_arg_e2e) ... ok
init_test_suite!(EchoTestSuite, echo_no_arg_e2e);
EchoTestSuite::run(TestConfig::default());
