println call in nargo tests should start on a new line

[vezenovm]

Problem

When running a test like such:

#[test]
fn test_multiple_prints()
{
    dep::std::println("hello");
    dep::std::println("world");
}

We will get this output:

[testing] Testing test_multiple_prints... "hello"
"world"

Happy Case

"hello" should start on the line after the test name.

[testing] Testing test_multiple_prints... 
"hello"
"world"

Hello, my name is Jakub and I am a student of Technical University in Kosice and software developer in Siemens Healthineers and I would be very happy if I could work on this issue. It would be the part of the course where we have to help a project on GitHub. Could you assign me to it, please?

Hi @yekxp! For sure, thank you for taking this on.

nargo test output changed a bit recently. If you run it with --show-output for the example above, this is the output:

[one] Running 1 test function
[one] Testing test_multiple_prints... ok
--- test_multiple_prints stdout ---
hello
world
-----------------------------------
[one] 1 test passed

So the output already starts in separate lines 🎉
