Istanbul instrumenter library.
|
||
|
|
|
||
|
|
Version 1.1.x now implements instrumentation using `Babel`. The implementation is inspired
|
||
|
|
by prior art by @dtinth as demonstrated in the `__coverage__` babel plugin.
|
||
|
|
|
||
|
|
It provides 2 "modes" of instrumentation.
|
||
|
|
|
||
|
|
- The old API that is mostly unchanged (except for incompatibilities noted) and
|
||
|
|
performs the instrumentation using babel as a library.
|
||
|
|
|
||
|
|
- A `programVisitor` function for the Babel AST that can be used by a Babel plugin
|
||
|
|
to emit instrumentation for ES6 code directly without any source map
|
||
|
|
processing. This is the preferred path for babel users. The Babel plugin is
|
||
|
|
called `babel-plugin-istanbul`.
|
||
|
|
|
||
|
|
Incompatibilities and changes to instrumentation behavior can be found in
