Learning Ionic - Second Edition

Executing unit tests

To start the execution process, we will add a script to the package.json file, so we can run tests easily by executing npm test from the command prompt/terminal.

Open package.json and add the following line to the scripts section:

"test": "karma start --reporters html ./test-config/karma.conf.js"

Now run the following command:

npm test

And you should see a browser launch and our test case execute. The command prompt/terminal log should look something like this:
