Investigate watcher interactions #7

Worse, of course, is that this breaks dependency tracking in the watcher. The loaded files will be from the build output, so AVA doesn't realize build files are dependencies of test files. If AVA could perform the path rewrites (or maybe invert them), it could track dependencies correctly. Combine that with knowing to wait for the build output of a specific test file to change and we're close to having a functional watcher again. Users should then configure AVA to ignore non-test file updates of sources, so that it's purely watching the build output. |

I think it would be nice if ava would use the watcher on the actual test files to decide which test to rerun, but only rerun those once the build files have also actually changed. That would be the result I would expect (even though all tests are technically rebuilt). Currently the Maybe ava could even have support for executing the precompilation step? |
Yes, that's what this issue is about.

Have the watcher ignore changes to the original TypeScript source files. This way, the watcher will only react to changes to the TypeScript build output. Allow the watcher to resolve the rewritten path of a test file, so it can track it as a dependency of the original TypeScript source file. This way, when the build output changes, the watcher knows to re-run the original test file. Update file patterns to ignore *.d.ts files, as well as any files in the build output. Updated the ignored-by-watcher patterns to ignore source map files from the build output. Fixes #10, #7, #9.

Fixed by #11. |
AVA's watcher may be watching both source files and the TypeScript build output. It must watch the source files, otherwise it won't know to rerun tests. But there's no point in rerunning tests until the build output has changed.
Delaying the watcher may work but this is not configurable. Perhaps if the watcher could figure out it should wait for a rewritten path to be updated too that may work. It'll require changes to how AVA and this package interact.
