My jasmine test seems to have gone into hiding, thanks to Karma and its sne

While attempting to execute my jasmine test, which is assessing my angular customer directive "book directive" utilizing the test-runner karma, I am encountering a series of output errors: (I'm receiving various TypeErrors from each script file, unable to even locate my test and identify a failing test)

How can I successfully run my tests?

Answer №1

Your main directory path should be set as basePath: '../',. Therefore, your files array must contain the following:

files: [
        "../scripts/angular.js",
       "../scripts/angular-route.js",
       "../scripts/angular-mocks.js",
       "../scripts/angular-sanitize.js",
       "../scripts/angular-scenario.js",
       "../scripts/jasmine.js",
       "../tests/newfeaturetests/directivetest.js",
       "../tests/test-main.js"
    ]

Please ensure that the base path is correct.

Also, make sure to review your index.html file to confirm that you have included all necessary JS scripts and listed them in the files Array. Failure to do so may result in errors if any of those scripts are dependencies for others.

In your jasmine test, remove the line beforeEach(module('Js/NewFeature/Book.html')); as it is incorrect and not a registered module name with the angular app.

Additionally, refer to the directive testing documentation for further information.
