simple-stacktrace
built this from the answers here https://github.com/visionmedia/mocha/issues/545 for the purpose of changing my stack traces from things like this:
1) Router POST /boards Import JSON column #1 has the right # of cards:
AssertionError: expected 0 to equal 5
+ expected - actual
+5
-0
at Context.<anonymous> (/Users/keyvan/Projects/mib/test/server/router_test.js:274:15)

to something more like this:
1) Router POST /boards Import JSON column #1 has the right # of cards:
AssertionError: expected 0 to equal 5
+ expected - actual
+5
-0
at Context.<anonymous> (test/server/router_test.js:274:15)
at processImmediate [as _immediateCallback] (timers.js:336:15)
which is easier to read and fits nicely without wrapping or robbing context
install
npm install simple-stacktrace
usage
mocha -w ./test/ 2>&1 | simple-stacktrace
options
These are passed in for you automatically when using the pipe form above. If you wish, you can use the following form.
require('simple-stacktrace')({
root: require('path').resolve(__dirname, '..')
})
This may be preferred for additional configuration, although in this case it would be better to expand on the simple-stacktrace
binary and allow it to accept these options:
root
: define where the root of your project lives if you want it to be stripped
node_modules
: a false
value hides any line that contains the string node_modules/ effectively hiding stack traces that occur outside your module. defaults to false
