Enable running tests with specific filter conditions:

The --filter option limits which test modules are executed by node test. The default pretest step is still node-gyp rebuild -C test, so npm test --filter=... still performs a full rebuild of the test addon targets before the filtered tests run.

Example:

• perform the default test rebuild, then run only the objectwrap test module

    npm test --filter=objectwrap

Wildcards are also possible:

Example:

• perform the default test rebuild, then run all test modules ending with reference (function_reference, object_reference, and reference)

    npm test --filter=*reference

Multiple filter conditions are also allowed

Example:

• perform the default test rebuild, then run all tests under threadsafe_function and typed_threadsafe_function, and also the objectwrap test module

    npm test --filter='*function objectwrap'
