Jasmine: Ways to invoke a function with a specific context parameter

Looking for guidance as a newbie to Jasmine on calling a method with context as a parameter.

Example: function locationInit(context) {
}

Appreciate any help and advice!

Answer №1

My approach would be to thoroughly debug and identify all possible values that context can have.

When it comes to writing tests, the method varies depending on the testing framework being used.

In my experience with AngularJS code, let's consider Angular as an example. If we have a service like the one below:

var app = angular.module('myApp', [])

app.service('serviceA', function() {
  return {
    methodName: function(context) {
      return context;
    }
  }
});

For testing the methodName from serviceA, here is how I would structure my test case:

describe('service: serviceA', function() {

  var serviceA;

  beforeEach(function() {
    module('myApp');
  });

  beforeEach(inject(function(_serviceA_) {
    serviceA = _serviceA_;
  }));

  describe('method: methodName', function() {
    it('should set up initial variables', function() {
      expect(serviceA).toBeDefined();
      var context = "Hello World!"
      expect(serviceA.methodName(context)).toEqual("Hello World! is the context.");
    });
  });
});

I hope this explanation helps you in understanding the process. The details provided were based on the information given in your question. If you require more assistance, please provide additional information such as the framework you are using, what specific aspect you wish to test (controller or service), etc.
