Define Sections
Sometimes it is useful to define sections of a page. Sections do 2 things:
- Provide a level of namespacing under the page
- Provide element-level nesting so that any element defined within a section is a descendant of its parent section in the DOM
Declare sections
You can create sections using the sections
property:
nightwatch/pages/samplePage.js
module.exports = {
sections: {
menu: {
selector: '#gb',
elements: {
mail: {
selector: 'a[href*="mail"]'
},
images: {
selector: 'a[href*="imghp"]'
}
}
}
}
};
Using sections in tests
Your tests would use it as follows:
tests/sampleTest.js
describe('sample test with page objects', function() {
it('Test', function (browser) {
var google = browser.page.google();
google.expect.section('@menu').to.be.visible;
var menuSection = google.section.menu;
menuSection.expect.element('@mail').to.be.visible;
menuSection.expect.element('@images').to.be.visible;
menuSection.click('@mail');
browser.end();
});
});
Note that every command and assertion on a section (other than
expect
assertions) returns that section for chaining. If desired, you can nest sections under other sections for complex DOM structures.
Nesting page object sections
nightwatch/pages/samplePage.js
module.exports = {
sections: {
menu: {
selector: '#gb',
elements: {
mail: {
selector: 'a[href*="mail"]'
},
images: {
selector: 'a[href*="imghp"]'
}
},
sections: {
apps: {
selector: 'div.gb_pc',
elements: {
myAccount: {
selector: '#gb192'
},
googlePlus: {
selector: '#gb119'
}
}
}
}
}
}
};
Using a nested section in your test is straightforward:
tests/sampleTest.js
describe('sample test with page objects', function() {
it('Test', function (browser) {
var google = browser.page.google();
google.expect.section('@menu').to.be.visible;
var menuSection = google.section.menu;
var appSection = menuSection.section.apps;
menuSection.click('@appSection');
appSection.expect.element('@myAccount').to.be.visible;
appSection.expect.element('@googlePlus').to.be.visible;
browser.end();
});
});
