You're using the syntax of jasmine-reporters 2.x with the 1.x branch. Specifically, you are passing an object of options but you need to send positional arguments.
Don't do this:
jasmine.getEnv().addReporter(new jasmine.JUnitXmlReporter({
savePath: "output/"
}));
Instead, you should do this:
jasmine.getEnv().addReporter(new jasmine.JUnitXmlReporter("output/"));
You can check out the source for the list of available options. Here are the current options:
/**
* Generates JUnit XML for the given spec run.
* Allows the test results to be used in java based CI
* systems like CruiseControl and Hudson.
*
* @param {string} [savePath] where to save the files
* @param {boolean} [consolidate] whether to save nested describes within the
* same file as their parent; default: true
* @param {boolean} [useDotNotation] whether to separate suite names with
* dots rather than spaces (ie "Class.init" not
* "Class init"); default: true
* @param {string} [filePrefix] is the string value that is prepended to the
* xml output file; default: 'TEST-'
* @param {boolean} [consolidateAll] whether to save test results from different
* specs all in a single file; filePrefix is then the whole file
* name without extension; default: false
*/
var JUnitXmlReporter = function(savePath, consolidate, useDotNotation, filePrefix, consolidateAll) {
/* ... */
}
