custom_test_frameworks
The tracking issue for this feature is: #50297
The custom_test_frameworks
feature allows the use of #[test_case]
and #![test_runner]
. Any function, const, or static can be annotated with #[test_case]
causing it to be aggregated (like #[test]
) and be passed to the test runner determined by the #![test_runner]
crate attribute.
#![feature(custom_test_frameworks)] #![test_runner(my_runner)] fn my_runner(tests: &[&i32]) { for t in tests { if **t == 0 { println!("PASSED"); } else { println!("FAILED"); } } } #[test_case] const WILL_PASS: i32 = 0; #[test_case] const WILL_FAIL: i32 = 4;
