Crate arch_test_core 

ArchTest

ArchTest is a rule based architecture testing tool. It applies static analyses on the specified rust project to extract use relationships.

Features

• Detect cyclic dependencies level wise or module wise
• Prohibit parent access
• Define layer relationships like MayNotAccess, MayOnlyAccess, MyNotBeAccessedBy, MayOnlyBeAccessedBy etc.
• For more access rules consult access_rules.

How to use it

You can use the Architecture struct in order to define your architecture. Afterwards you check it for failures.

let architecture = Architecture::new(hash_set!["analyzer".to_owned(), "parser".to_owned(), ...])
.with_access_rule(NoParentAccess)
.with_access_rule(NoModuleCyclicDependencies)
.with_access_rule(NoLayerCyclicDependencies)
...
.with_access_rule(MayNotAccess::new(
    "materials".to_owned(),
    hash_set!["tests".to_owned()],
    true,
));
let module_tree = ModuleTree::new("src/lib.rs");
assert!(architecture.validate_access_rules().is_ok());
assert!(architecture.check_access_rules(&module_tree).is_ok());

If you are interested in the failure you can pretty print it like this:

architecture.check_access_rules(&module_tree).err().unwrap().print(module_tree.tree());
