Needs Environment Variable

Early return from a test (or method in general) if an environment variable is undefined or does not match a specific value.

Example

some_test will be skipped if MY_ENVIRONMENT_VARIABLE is not defined (example 1) or does not match 1 (examples 2).

use needs_env_var::*;

#[needs_env_var(MY_ENVIRONMENT_VARIABLE)]
#[test]
fn some_test() {
    assert!(1 == 1);
}

// or if its specified value not matched
#[needs_env_var(MY_ENVIRONMENT_VARIABLE=1)]
#[test]
fn some_test() {
    assert!(1 == 1);
}
