dylint_testing

This crate provides convenient access to the compiletest_rs package for testing Dylint libraries.

Specifically, this crate provides the following three functions. Note: If your test has dependencies, you must use ui_test_example or ui_test_examples. See the question_mark_in_expression example in this repository.

ui_test - test a library on all source files in a directory
```
pub fn ui_test(name: &str, src_base: &Path)
```
- name is the name of a Dylint library to be tested. (Often, this is the same as the package name.)
- src_base is a directory containing:
  - source files on which to test the library (.rs files), and
  - the output those files should produce (.stderr files).
ui_test_example - test a library on one example target
```
pub fn ui_test_example(name: &str, example: &str)
```
- name is the name of a Dylint library to be tested.
- example is an example target on which to test the library.
ui_test_examples - test a library on all example targets
```
pub fn ui_test_examples(name: &str)
```
- name is the name of a Dylint library to be tested.

For most situations, you can add the following to your library's lib.rs file:

#[test]
fn ui() {
    dylint_testing::ui_test(
        env!("CARGO_PKG_NAME"),
        &std::path::Path::new(env!("CARGO_MANIFEST_DIR")).join("ui"),
    );
}

And include one or more .rs and .stderr files in a ui directory alongside your library's src directory. See the examples in this repository.

Additional documentation on compiletest_rs can be found in its repository.
