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!();
}
