How to reuse beforeEach/afterEach in Jasmine JS?

Question

When writing tests with JasmineJS I have many tests that have similar beforeEach/afterEach code.

Is there a way to implement an inheritance model using JasmineJS test suites?

I can group all tests in a single describe but in this case I will end with a single HUGE JS file containing all tests.

I would like to split the tests for each page.

Here is an example:

describe('Services Page', function() {

    beforeEach(function() {
        login_as_admin()
    })

    beforeEach(function() {
        browser().navigateTo('/services')
    })

    if('Some test for services page', function() {})

    afterEach(function() {
        logout()
    })

})


describe('Administrators Page', function() {

    beforeEach(function() {
        login_as_admin()
    })

    beforeEach(function() {
        browser().navigateTo('/administrators')
    })

    if('Some test for administrators page', function() {})

    afterEach(function() {
        logout()
    })

})

I think this is partially examined in this blog post and also answered here but i'm adding an adapted answer for your example:

Reusable code:

function sharedSetup(startPage) {
    beforeEach(function() {
        login_as_admin();
        browser().navigateTo(startPage);
    });

    afterEach(function() {
        logout();
    });
};

How to use it:

describe('Services Page', function() {
    sharedSetup('/services');

    it('Some test for services page', function() {});
});

describe('Administrators Page', function() {
    sharedSetup('/administrators');

    it('Some test for administrators page', function() {});
});
