    <p>I have two prototypes I want to test:</p> <pre><code>var Person = function() {}; Person.prototype.pingChild = function(){ var boy = new Child(); boy.getAge(); } var Child = function() {}; Child.prototype.getAge = function() { return 42; }; </code></pre> <p>What exactly I want to test: <strong>to check that <code>getAge()</code> method is called inside of the <code>pingChild()</code> method</strong></p> <p>That is Jasmine specs I try to use for this purpose:</p> <pre><code>describe("Person", function() { it("calls the getAge() function", function() { var fakePerson = new Person(); var chi = new Child(); spyOn(fakePerson, "getAge"); fakePerson.pingChild(); expect(chi.getAge).toHaveBeenCalled(); }); }); describe("Person", function() { it("calls the getAge() function", function() { var fakePerson = new Person(); spyOn(fakePerson, "getAge"); fakePerson.pingChild(); expect(fakePerson.getAge).toHaveBeenCalled(); }); }); describe("Person", function() { it("calls the getAge() function", function() { var fakePerson = new Person(); var chi = new Child(); spyOn(chi, "getAge"); fakePerson.pingChild(); expect(chi.getAge).toHaveBeenCalled(); }); }); </code></pre> <p>but all of them shows just errors:</p> <blockquote> <ul> <li>getAge() method does not exist</li> <li>getAge() method does not exist</li> <li>Expected spy getAge to have been called</li> </ul> </blockquote> <p><em><strong>So, is there any way to test such cases using Jasmine, and if yes - how can it be done?</em></strong></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
