Define Anchor functions only for tests

Question

I'm writing an Anchor program and would like to include a couple functions that modify certain values during tests in a way that would be tedious to do with the real program interface. I don't want to keep this for my production code. What is the standard way of doing this in Anchor?

Answer 1

You should be able to use conditional compiling like this:

#[cfg(feature = "is-test")]
pub fn increase_counter_function(mut count: u64) -> u64 {
    count += 1;
    count
}

and then you set the value in the cargo.toml

[features]
is-test = []
