问题
I'm using Karma and Jasmine for testing my Angular JS code. I managed to run all the tests in my project using Karma, but if I try to run just a single file I'm getting the following error: ReferenceError: describe is not defined. Is it possible to run just a single test file and if yes then how?
P.S. I'm using Intellij IDEA.
回答1:
Although it's not ideal, you can replace describe (and it) with fdescribe (and fit) so only those tests will be executed
On the other hand, xdescribe / xit excludes the tests from your suite
If you use Gulp, you can combine gulp-karma & yargs to pass in a pattern as argument.

If you are like me and you've inherited a suite of tests that are controlled by a task runner (e.g. gulp) and you are getting failures but are unsure which file is actually failing you can sanity check an individual file by running jasmine directly against it:
1.) Make sure you have jasmine installed (it may not be if wrapped inside your task runner configuration)
npm install jasmine
2.) Run jasmine against file:
./node_modules/.bin/jasmine /path/to/my/spec/file.js
or
./node_modules/jasmine/bin/jasmine.js /path/to/my/spec/file.js
