-"""Wraps jscoverage to instrument a single file more efficently. |
- |
-JScoverage crawls directories recursively to copy and instrument everything |
-under a directory. This turns out to be too slow for our use, because our |
-generated .js files live in directories with > 100K files. Even though |
-jscoverage has a flag ('--exclude') to skip some files for |
-instrumentation/copying, it stills crawls recursively everything under the |
-directory. |
- |
-This script is a simple wrap on top of jscoverage. It creates a temporary |
-directory, copies the file we want to instrument alone, and runs jscoverage |
-within this small directory. |
