A lib help you run test with condition

Environment Variable

Run test case when the environment variable is set. A solution for this issue of rust-lang.

```rust

[cfg(test)]

mod tests {

// PWD environment variable exists
#[test_with::env(PWD)]
fn test_works() {
    assert!(true);
}

// NOTHING environment variable does not exist
#[test_with::env(NOTHING)]
fn test_ignored() {
    panic!("should be ignored")
}

} ```

Result of cargo test ```text running 2 tests test tests::testignored ... ignored test tests::testworks ... ok

test result: ok. 1 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 0.00s ```

If the test depends on more than one environment variables, you can write it with multiple variables, #[test_with::env(VAR1, VAR2)].

File/Folder

Run test case when the file or folder exist. This is good for testing with database config. If you want to check the folder exist or not, please use path.

```rust

[cfg(test)]

mod tests {

// hostname exists
#[test_with::file(/etc/hostname)]
fn test_works() {
    assert!(true);
}

// nothing file does not exist
#[test_with::file(/etc/nothing)]
fn test_ignored() {
    panic!("should be ignored")
}

// etc exists
#[test_with::path(/etc)]
fn test_works_for_path() {
    assert!(true);
}

} ```

If the test depends on more than one file or path, you can write it with multiple file/path, #[test_with::file(/file1, /file2)] or #[test_with::path(/folder, /file)].

Http/Https Service

Run test case when the http/https service available. This is good for integration testing.

```rust

[cfg(test)]

mod tests {

// https service exists
#[test_with::https(www.rust-lang.org)]
fn test_works() {
    assert!(true);
}

// There is no not.exist.com
#[test_with::https(not.exist.com)]
fn test_ignored() {
    panic!("should be ignored")
}

} ```

If the test depends on more than one service, you can write it with multiple service, #[test_with::http(service1, service2)] or #[test_with::http2(service1, service2)].

TCP socket

Run integration test case when the remote tcp socket is listening.

```

[cfg(test)]

mod tests { #[testwith::tcp(8.8.8.8:53)] fn testworks() { assert!(true); }

#[test_with::tcp(193.194.195.196)]
fn test_ignored() {
    panic!("should be ignored")
}

} ```

Remote Server Online Status

Run integration test case when the remote server online. Please note the user running test case should have capability to open socket.

```

[cfg(test)]

mod tests {

// localhost is online
#[test_with::icmp(127.0.0.1)]
fn test_works() {
    assert!(true);
}

// 193.194.195.196 is offline
#[test_with::icmp(193.194.195.196)]
fn test_ignored() {
    panic!("should be ignored")
}

} ```
