Webdriver.IO: How do I run a specific 'it' statement in Jasmine using WDIO

Question

I am trying to pull out a smoke suite from my regression suite written using the Jasmine framework (wdio-jasmine-framework).

Is it possible to just add a tag on specific testcases in Jasmine?

Answer 1

If I remember correctly from my Jasmine/Mocha days, there were several ways to achieve this. I'll detail a few, but I'm sure there might be some others too. Use the one that's best for you.

1. Use the it.skip() statement inside a conditional operator expression to define the state of a test-case (e.g: in the case of a smokeRun, skip the non-smoke tests using: (smokeRun ? it.skip : it)('not a smoke test', () => { // > do smth here < });).

Here is an extended example:

// Reading the smokeRun state from a system variable:
const smokeRun = (process.env.SMOKE ? true : false);

describe('checkboxes testsuite', function () {

    // > this IS a smoke test! < //
    it('#smoketest: checkboxes page should open successfully', () => {
        CheckboxPage.open();
        // I am a mock test... 
        // I do absolutely nothing!
    });

    // > this IS NOT a smoke test! < //
    (smokeRun ? it.skip : it)('checkbox 2 should be enabled', () => {
        CheckboxPage.open();
        expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(false);
        expect(CheckboxPage.lastCheckbox.isSelected()).toEqual(true);
    });

    // > this IS NOT a smoke test! < //
    (smokeRun ? it.skip : it)('checkbox 1 should be enabled after clicking on it', () => {
        CheckboxPage.open();
        expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(false);
        CheckboxPage.firstCheckbox.click();
        expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(true);
    });
});

2. Use it.only() to achieve mainly the same effect, the difference being the test-case refactor workload. I'll summarize these ideas as:

• if you have more smoke tests than non-smoke tests, use the it.skip() approach;
• if you have more non-smoke tests than smoke tests, use the it.only() approach;

You can read more about pending-tests here.

3. Use the runtime skip (.skip()) in conjunction with some nested describe statements.

It should look something like this:

// Reading the smokeRun state from a system variable:
const smokeRun = (process.env.SMOKE ? true : false);

describe('checkboxes testsuite', function () {

    // > this IS a smoke test! < //
    it('#smoketest: checkboxes page should open successfully', function () {
        CheckboxPage.open();
        // I am a mock test... 
        // I do absolutely nothing!
    });

    describe('non-smoke tests go here', function () {
        before(function() {
            if (smokeRun) {
                this.skip();
            }
        });
        // > this IS NOT a smoke test! < //
        it('checkbox 2 should be enabled', function () {
            CheckboxPage.open();
            expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(false);
            expect(CheckboxPage.lastCheckbox.isSelected()).toEqual(true);
        });
        // > this IS NOT a smoke test! < //
        it('checkbox 1 should be enabled after clicking on it', function () {
            CheckboxPage.open();
            expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(false);
            CheckboxPage.firstCheckbox.click();
            expect(CheckboxPage.firstCheckbox.isSelected()).toEqual(true);
        });
    });
});

!Note: These are working examples! I tested them using WebdriverIO's recommended Jasmine Boilerplace project.

!Obs: There multiple ways to filter Jasmine tests, unfortunately only at a test-file(testsuite) level (e.g: using grep piped statements, or the built-in WDIO specs & exclude attributes).
