Lately, I've been lending a hand in shaping the jquery.datatables definition over at DefinitelyTyped. Within the repository, you'll find numerous other definition projects, but it's not rare for one or more of them to stumble when put through the test runner (npm test). It baffles me how a fresh pull from the repo can fail like this. Is there any method to limit the test runner to just my specific definition?
Another useful tip alongside wd39's solution is to execute npm run lint jquery.datatables if there is a tslint.json file in the package. This command will both lint and compile a specific package.
As outlined in the DefinitelyTyped README:
Updating an existing package
...
* To edit a package with atslint.json, usenpm run lint package-name. For those without it, just runtscin the package directory.
Occasionally, this issue may arise in larger projects. However, there is a simple solution. You can call upon the TypeScript compiler directly for the type definitions you have generated by using a command like (assuming your project directory is named jquery.datatables):
tsc --project types/jquery.datatables/tsconfig.json
It's important that the configuration is properly set up and already in place. Alternatively, you could attempt running it directly with:
tsc --noEmit types/jquery.datatables/jquery.datatables-tests.ts
Keep in mind, this approach might raise issues if there are dependencies on other files. Using the --noEmit option prevents TSC from generating unnecessary JavaScript code, which could result in complaints from DefinitelyTyped's tests (indicating unused files that should not be included in version control).
