Soft-Test-Failures
Multiple test failures, any one of which will result in a failed test. Like gtest's EXPECT_*
rather than ASSERT_*
.
#[test]
fn expect_failures() {
let x = 4;
let y = "is not";
let z = 5;
expect!(2 + 2 == 5, "{} surely {} {}", x, y, z);
expect!(1 + 1 == 2);
expect!(3 - 7 == -4);
expect!(3 - 7 == -3);
let_fail!();
}

lib.rs
:
This crate trackes assertions during the execution of a test, delaying panicks until the end of execution. This ensures that if two assertions were to fail, the first does not clobber the second. This is most useful when writing large tests with many assertions that may begin to fail simultaneously, as you can pinpoint exactly which ones failed.
Usage
Replace your normal assert!()
assertions with expect!()
from this crate. At the end of your test, call let_fail!()
#[test]
fn expect_failures() {
let x = 4;
let y = "is not";
let z = 5;
expect!(2 + 2 == 5, "{} surely {} {}", x, y, z);
expect!(1 + 1 == 2);
expect!(3 - 7 == -4);
expect!(3 - 7 == -3);
let_fail!();
}
