How can I build a basic Page Object Model for login testing in Puppeteer using Node/ES7? For example:
(async () => {
const browserInstance = await require('puppeteer').launch();
const loginScreen = await browserInstance.newPage();
await loginScreen.goto('http://example.com', { timeout: 4000 });
await loginScreen.waitForSelector('input#username');
await loginScreen.type('input#username', 'Alice');
await loginScreen.type('input#password', 'secret123');
await loginScreen.click('button.login');
await loginScreen.waitForSelector('div.success');
await browserInstance.close();
})();
I implemented a similar approach where I encapsulated page specific functions into a dedicated class, which greatly improved the clarity of my tests. For example, I created a LoginPage class that wraps the Puppeteer page instance and provides methods like enterUsername, enterPassword, and submitLogin. This separation allowed for reusable code and simplified maintenance when selectors change or additional validations are required. In my experience, this method reduces repetitive code and makes the overall device easier to scale and debug.
I have been utilizing the Page Object Model approach in my Puppeteer projects for several months now. My implementation involves creating small utility classes that manage specific web page functions, such as handling navigation and form submissions. I found that this setup not only increases code maintainability but also drastically reduces the overhead when updating selectors or adding new features. This method made debugging much more straightforward as I could easily track issues back to individual page methods, and overall it streamlined my test workflow.
hey charlie, tried splitting funcs into tiny page classes. helps alot when updating selectors cuz u only change one place. its real messy if u keep everything in one block. works pretty well and keeps tests clean, in my exp.
