nightwatch-data-driven

Provides tool for emulating data driven tests in Nightwatch.js.

Forked from https://github.com/wsbaser/nightwatch-data-driven

Installation

npm i nightwatch-data-driven --save

Example 1: Simple usage

1. Create DataDrivenTest instance passing a browser object, provided by Nightwatch and function representing the body of the test (the ArrangeActAssert function).
2. Call forCases method with object containing names and data for test cases. Use disabled parameter to deactivate test case(see example).

import DataDrivenTest from 'nightwatch-data-driven';
import {authConfig}  from '../configs/auth';

var test = {
    before: function (browser) {
        browser.init();
    },
    'Valid credentials => successfull login': function (browser) {
        // . Initialize DataDrivenTest with browser and AAA function
        //   and call it for a set of test cases
        new DataDrivenTest(browser, function(data, name){
            // . Arrange
            browser.logout();
            // . Act
            browser.page.login().loginAndWaitForRedirect(data.email, data.pass);
            // . Assert
            browser.page.workspace().assertIsCurrentPage(name);
        })
        .forCases({
            "Valid credentials": {email: authConfig.main.EMAIL, pass: authConfig.main.PASS},
            "Ignore leading space in email": {email: ' ' + authConfig.main.EMAIL, pass: authConfig.main.PASS},
            "Email in upper case": {
                email: authConfig.main.EMAIL.toUpperCase(),
                pass: authConfig.main.PASS,
                disabled: true
            }
        });
    },
    after: function (browser) {
        browser.end();
    }
};
export = test;

Example 2: Building and reusing of "test blanks"

1. Create DataDrivenTest instance without parameters for our "test blank".
2. Call withArrange method passing Arrange function of "test blank".
3. Call withAct method passing Act function of "test blank".
4. Call withBrowser method(in before hook for example), passing Nightwatch browser object.
5. Now you can reuse "test blank" calling withAssert and forCases methods with different Assert functions and data in each particular test.

import DataDrivenTest from 'nightwatch-data-driven';
import {mother} from '../mother';

// . Create "test blank"
let submitLoginForm = new DataDrivenTest()
	.withArrange(function(cb) {
		this.browser.logout(cb)
	})
	.withAct(function(dt) {
		this.browser.page.login().section.loginForm.fillAndSubmit(dt.email, dt.pass)
	});
	
 var test = {
    before: function (browser) {
        browser.init();
        // . Initialize "test blank" with browser
        submitLoginForm.withBrowser(browser);
    },
    'Login is invalid email: show error': function (browser) {
        // . Use "test blank" with specific assertion and test cases
        submitLoginForm
            .withAssert((dt, nm) => browser.page.login().assertNoProgress(nm))
            .forCases({
                "1. ": {email: "a", pass: mother.Valid.PASS},
                "2. ": {email: "@b", pass: mother.Valid.PASS},
                "3. ": {email: "@b.", pass: mother.Valid.PASS},
                "4. ": {email: "@b.c", pass: mother.Valid.PASS},
                "5. ": {email: "a@b", pass: mother.Valid.PASS},
                "6. ": {email: "a@b.", pass: mother.Valid.PASS},
                "7. ": {email: "a@b.c", pass: mother.Valid.PASS},
                "8. ": {email: "й@ц.ук", pass: mother.Valid.PASS},
            });
    },
    'Login is valid email: show progress': function (browser) {
        // . Use "test blank" with specific assertion and test cases
        submitLoginForm
            .withAssert((dt, nm) => browser.page.login().assertProgressDisplayed(nm))
            .forCases({
                "1. ": {email: "[e-mail]"},
                "2. ": {email: "1#$%&'*+/=?^-_`{|}~[e-mail]"},
                "3. ": {email: "[e-mail]"},
                "4. ": {email: "a@b.12"}
            });
    },
    after: function (browser) {
        browser.end();
    }
}
export = test;
