Testing your modules

Ryna allows you to annotate functions in order to test your modules. Let's take a look at how.

Creating tests

In order to create a test you have to annotate a function with the @test annotation, which takes no arguments. This function must take no arguments and must return a logical value. The test will be considered successful if and only if the function returns true. Let's take a look at an example extracted from prelude:

@test
fn fill_test() -> Bool {
    let res = arr_with_capacity<Int>(3);
    res.fill(100);

    for i in res {
        if i != 100 {
            return false;
        }
    }

    return true;
}

This test should always pass, since it's filling an array with a value and then checking the contents, but this can be useful when changing your code or when programming with TDD.

Testing

In order to execute the tests inside your module you have to use the use the following command:

ryna run <PATH> --test

You can also add optimization and recompilation flags, as seen in the Getting Started section.
