Testing

We have a very rudimentary test script since there is not much else that we need. To write a test, create a file named test_<description>.js inside /tests/source?/. Tests have this format:

<source_program>
// expected output

Note that only the last line is taken as expected output. For the program to even compile it must also be a proper Source comment. Spaces immediately after // does not matter. To test multiple things at the same time, it may be useful to know that display() is varag and you can do display(a,b,c) for example. It is most helpful to look at existing tests and copy/paste them.

There might be some quirks that one must keep in mind to write tests. These occur because there is no effort put into sanitizing things because it is not needed right now.

• All numbers are double. Printed numbers go to 6 decimal places, even for example display(3)
• Booleans are int1. Therefore display(true) gives 1, and display(false) gives 0.
• Display spaces out its arguments with a single space.
