+In preparation for the epoch release, we will continue to invest in Rust’s library ecosystem in four ways:
 
 
 - **Quality**. Building on our 2017 work, we will bring the API Guidelines to a 1.0 status and build out additional resources to aid library authors.
 - **Discoverability**. We will continue to work with the crates.io team on discoverability improvements, as well as push the Cookbook (or something like it) to 1.0 status as a means of discovering libraries.
 - **Domain-specific content**. We will work with library authors in the four domains of focus this year to sharpen our offerings in each domain (elaborated more below).
+- **Testing**. To ensure the quality of these offerings, we will also work with authors of testing libraries to make testing easy and more widely used. A working group for testing, reporting to the core team, will be formed to consolidate efforts and strive for better integration.

 And a couple of goals that are probably a stretch for 2018 at all, let alone for the epoch release:
 
-- **Custom test frameworks**. There’s been [a lot of interest in this area](https://internals.rust-lang.org/t/past-present-and-future-for-rust-testing/6354/1), and it may be possible that with a dedicated working group we can implement and stabilize test frameworks in 2018.

If not, custom test frameworks should at least be available as an unstable feature and a merged eRFC, such as [RFC 2318](https://github.com/rust-lang/rfcs/pull/2318), with which we may gain confidence.
 - **Compiler-driven code completion for the RLS**. Today the RLS still uses a purely heuristic approach for auto-completion. If the compiler’s new “query-based” architecture can be pushed far enough during the year, it maybe become feasible to start using it to deliver precise auto-complete information.
