Hi, I tryed to reproduced your example, but I'm blocked on the error about the button "Generate File" visibility. I'm using playwright as NBomber project extention. Any suggestion ? how I can set a different timeout on a single element in my code ? thanks.

[@vijayalakshmivenkatesan2084]

Thanks for the video Koushik. How did you manage to download the file in that particular location? Where we need to add the path for this?

[@LambdaTest]

Hey Vijayalakshmi, In order to download a file to a specific location using Selenium, you can use the "download.default_directory" Chrome option to specify the path to the desired directory. We can create a ChromeOptions object and add an experimental option to it. The "download.default_directory" option specifies the path to the desired download directory. Note: You'll need to replace "/path/to/download/directory" with the actual path to the directory on your system. I hope this helps! Let me know if you have any other questions.

Thank you it was really helpful as I am new to playwright this basic example will help me to perform my task.

[@LambdaTest]

Glad it was helpful! 😇

How do you explicitly download and save as a file in a specific folder by providing a path?

[@LambdaTest]

Hey Almas, With Playwright, you can intercept file chooser dialogs and direct downloads to your desired path, Please refer to the sample code: const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch(); const page = await browser.newPage(); await page._setFileChooserIntercepted(true); page.on('filechooser', async (fileChooser) => { await fileChooser.setFiles('/your/download/path'); }); await page.goto('website.com/downloadlink'); await page.click('button#downloadButton'); await page.waitForTimeout(10000); // wait for download await browser.close(); })(); Let us know if this works

Hey @LambdaTest, how to download a PDF which has a href tag but the url does not contain any .pdf extension.

[@LambdaTest]

Hey Maruf, To download a PDF file that has a href tag but the URL does not contain any .pdf extension, you can use the fetch API in Playwright with TypeScript to retrieve the file as a response object and then save it as a PDF file.

Thank you, but I have no Input Object or "file" in the button for uploading files , what can I do?

[@LambdaTest]

Hey there, If there's no input field for file upload, the site may use a JavaScript-based upload mechanism. Playwright can handle this by intercepting the file picker dialog when clicking the upload button: const [fileChooser] = await Promise.all([ page.waitForEvent('filechooser'), page.click('button[id="upload-button-id"]'), // replace with your actual selector ]); await fileChooser.setFiles('path/to/your/file');

[@s.harihari3796]

waitforEvent('filechooser') is just stopping the execution, not even terminatingn the execution both setFiles and Setinputfiles cant able to upload the files in mac

[@LambdaTest]

Hey there, This issue might occur if the event you are waiting for is never emitted, often because the action that triggers the file chooser dialog in the application isn't occurring as expected. Here are a few steps to debug the issue: - Ensure Trigger is Working: Make sure that the action which is supposed to trigger the file chooser is working as intended. If it's a button click or any other event, confirm that it is properly automated in your script and that it's actually happening in the browser. - Correct Event: Confirm that you are waiting for the correct event. Playwright's waitforEvent is case-sensitive and should match exactly with the event being listened to. - Timing Issues: There could be a timing issue where the waitforEvent is called after the event has already been emitted. Ensure that the waitforEvent call precedes the action that triggers the file chooser. - Context and Page Instances: Ensure that you are waiting for the event on the correct context and page instances where the file chooser is expected to appear. Please let us know if this helps.

Bro, when you performed manually, you got windows pop up, but with playwright, it downloaded without showing up wundiws pop up. I tried yout code, but still it's throwing pop up.

[@LambdaTest]

Hey Pavan, Thanks for reaching out. If you're experiencing a pop-up, it might be due to different browser settings or some other script interfering. Can you please check are you on the lastest Playwright version. If you are still facing the issue, please reach us out at [e-mail] and we help resolve them.

[@MoriaHilaArama]

hi, the click on download button doesn't performed because of waiting to the download event... the error: Test timeout of 80000ms exceeded. page.waitForEvent: Page closed =========================== logs =========================== waiting for event "download" ============================================================

[@LambdaTest]

Hey Moria, Can you please run the test in debug or headed mode and see where the test is stuck. Refer here : playwright.dev/docs/debug

Hello, how can I upload file using Mac

[@LambdaTest]

Hey Khe, You can upload the file similarly with FileChooser class to select the file you want to upload.

[@parimalajangam76]

what if i want to upload multiple files, getting error by passing multiple paths in array

[@LambdaTest]

Hey Parimala To upload multiple files in Playwright, navigate to the page, select the file input element, and use setInputFiles() with an array of file paths. Ensure the input element has the multiple attribute to allow multiple file selection. If errors persist, provide more details for further assistance.

This code not working with plupload non-input field.

[@LambdaTest]

Handling file uploads, especially with non-input elements like those managed by Plupload, can be challenging in automated tests due to the way these elements are typically scripted to handle files differently from standard HTML input elements. Playwright offers several ways to interact with the web elements and automate file uploads, but when dealing with complex JavaScript implementations like Plupload, you might need to take a different approach. Here are some general strategies you can try with Playwright to handle file uploads for non-input fields, such as those managed by Plupload: 1. Use JavaScript to Set the File Directly (if possible) Some applications allow you to set the file path directly onto the JavaScript object managing the upload. This would involve using Playwright’s page.evaluate() function to execute custom JavaScript within the context of the page: await page.evaluate(() => { // Assuming there's a JavaScript function or Plupload configuration that can be manipulated to set the file directly window.pluploadInstance.files.add(/* file details */); window.pluploadInstance.start(); // Start the upload }); This approach requires a good understanding of how the file upload is implemented on the website you are testing. 2. Interact with the File Picker Dialog If the Plupload component triggers a file picker dialog, you can use Playwright's capability to listen for the dialog event and interact with it: const [fileChooser] = await Promise.all([ page.waitForEvent('filechooser'), // Wait for the file chooser dialog to open page.click('selector-for-upload-button'), // Trigger the file chooser dialog ]); await fileChooser.setFiles('path/to/file'); This method works if the action on your page triggers the native file picker dialog.

[@akshaylohana1256]

Getting the error as: TypeError: Cannot read properties of undefined (reading 'suggestedFilename'), looks like suggestedFilename is not working for my code and also the file is getting download with alpha-numeric name. Please suggest how to resolve this.

[@akshaylohana1256]

Working now... Thanks!
