Macro forgetest_init

macro_rules! forgetest_init {
    ($(#[$attr:meta])* $test:ident, |$prj:ident, $cmd:ident| $e:expr) => { ... };
    ($(#[$attr:meta])* $test:ident, $style:expr, |$prj:ident, $cmd:ident| $e:expr) => { ... };
}

Same as forgetest but returns an already initialized project workspace (forge init)
