Is this the best way to use expectEqual
?
fn add(a: i64, b: i64) i64 {
return a + b;
}
test "basic test" {
try std.testing.expectEqual(@as(i64, 10), add(3, 7));
}
Without the @as
the test doesn’t even compile:
./src/main.zig:12:40: error: expected type 'comptime_int', found 'i64'
try std.testing.expectEqual(10, add(3, 7));
Having to use @as
seems makes the test less readable. It seems to me inferring the type of expected
from the type of actual
would make more sense.
I am not sure if there is already an issue for this. But I usually just switch expected with actual in the arguments. As you mentioned, reading the failing test output is then harder obviously.
