after the codegen. Any requests that a page does, including XHRs and fetch requests, can be tracked, modified and handled. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The following snippet would not be a subject to cors and will give access to the raw bytes. But yes I agree that Playwright is a lot better than Cypress. A that completes when the json body is parsed, yielding a representation of response body. const response = await page.waitForResponse(as. My team is working against several single page applications that will likely already be running locally. 02 Solution 1 03 Solution 2 04 Solution 3 05 Final Words Solution 1 I would use waitForResponse that will return the response matching the predicate. For example, the page fixture provides a new web page to run a test. @mxschmitt perhaps you could call it .fetch() instead of ._request() on the Page & BrowserContext to avoid confusion with browser request events. Have a question about this project? Now that I read you request to the end, I see that you use different state for each test. FYI there's https://github.com/apify/got-scraping that mimics the browser fingerprint as closely as possible (TLS, headers casing, headers order etc.). I've updated my example TypeScript project to include these API calls directly using both page and request which looks like: 1. The English language draws a terminological distinction (which does not exist in every language) between translating (a written text) and interpreting (oral or signed communication between users of different languages); under this distinction, translation can begin only . I don't know that it's core to my use case, though. I can see the request response in chrome developer tools network tab while making the program. edited by pavelfeldman. When server is updated I will re-create snapshots. // It is important to call waitForEvent before click to set up waiting. Emitted when a request finishes successfully after downloading the response body. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Check your inbox or spam folder to confirm your subscription. This plugin configures pytest fixtures that provide building blocks you need for end-to-end browser testing. Besides the perf tests it can do everything youve asked for in your answer. @mxschmitt a+b this would also be great for supporting performance testing. The api call I was trying to make was a POST request to a files endpoint to upload a file, in the below case a .png. 10 contemporary playwrights you should know - UNCSA A Night of Thoughtful Fright Oct 31, 2022 Oskar Espina-Ruiz, Clarinet, and Dmitri Vorobiev, Piano, in Recital Nov 1, 2022 Omar Thomas with the UNCSA Wind Ensemble and the Piedmont Wind Symphony Nov 4, 2022 Another example: managing test data, for example, deleting a user on the backend after the test. I personally like ruby's VCR implementation which allows you to wrap any code block to check & record the extrenal requests and save it as a file, then reuse it for future runs. @lifeart I have updated my lib (playwright-request-mocker), now it can read an existing HAR file also, sorry for the delay. At the moment I am writing autotests for two projects, I use cypress on one and Playwright on the other, so I involuntarily start comparing these tools, each has pros and cons. Would it be possible to detect that we are retrying a test and only configure page.routeFromHAR if this is the case? Your email address will not be published. Additionally, I haven't actually started using Playwright yet. The endpoint specified that the request of type multipart/form-data would be required. Yeah, you have to call context.cookies on the current status of the context. But you are right cy will also not work. Also would be great if the requested feature would work with other runners, not just @playwright/test. The text was updated successfully, but these errors were encountered: It sounds like you want to serve network requests from a har file, and also a cli command to record a har file. Have you checked out playwright? 'use strict'; const playwright = require('playwright-aws-lambda'); module.exports.pltest = async event => { let browser = null; try { const browser = await playwright.launchchromium(); const context = await browser.newcontext(); const page = await context.newpage(); page.on('request', request=> { let url = request.url(); let body = I might be running a web server that serves my static files and I want to mock only XHR requests to the backend. cors issue (sometime even have to disable security feature) etc. FairyDust only knows how to check the expiration of the auth token, to request a new one from BigApp. 1. Search: Puppeteer Intercept Request Response. Hi, @mxschmitt. to your account. 409K impressions in July22. See here: https://playwright.dev/docs/next/api-testing. Single file upload Here we are using the setInputFiles playwright method to select the files for file upload. Closing since we're releasing it with v1.16. Notice below that we need to pass some body as part of POST request (unlike a GET request) . It sounds like it could be useful for exercising multiple test cases, but that sounds like it may also be outside my initial use case. But that makes whole browser unsafe. The (mostly) proprietary testing software testIM (which uses playwright under the hood), provides this feature, and it really is very useful. In firefox we can't even disable cors which is problem in my opinion, @shirshak55 thanks for your reply, still trying to better understand your requirements. Use case: Features: response.body () Added in: v1.8 returns: < Promise < Buffer > > Returns the buffer with response body. And I can't have a full environment for testing. To install Playwright, the plugin, and the browsers to test on, run: pip install playwright pytest-playwright python -m playwright install. 3. The size of the file gets too big when there are static assets (js chunks ). The mentioned code doesn't use Playwright API to fill inputs or click a button. Playwright sends requests from Node.js so it's resilient and fast. We debated that among other options and decided to stick with page.request.get() and context.request.get(). I currently use Cypress for my automation testing framework, however I am toying with the idea of moving over to Playwright. There are problems with using got etc. Current workflow looks something like that: Playwright opens headless chromium Opens first page with captcha (no data) Solves captcha and redirects to the page with data Thanks for the great work! A Software Quality Site by Alister B Scott, Selecting hard to identify elements with Playwright, Five reasons why Playwright is better than Cypress. By clicking Sign up for GitHub, you agree to our terms of service and This all could be encapsulated in a helper function but the idea is the same - you work with the web page and at some point use its cookies to send a custom request from playwright. I have read the docs about how Playwright can re-use application state but this is not really a viable solution for me because after each test I specifically use new application state. The main reason I like using browser over node is I can debug it easily. Playwright is a Node library to automate the Chromium, WebKit and Firefox browsers as well as Electron apps with a single API. @mxschmitt @dgozman is there any plans to implement this in near future? You are right that I havent tried to use Playwright for API testing the way you have, so I have that on my to-do list now. Then the response is returned. to your account. Sign in It can also store cookies for the API requests. When the server responds with a redirect, Playwright creates a new Request object. https://stackoverflow.com/a/69551330/143475, https://twitter.com/ptrthomas/status/1307678474627244032, https://nodejs.org/en/knowledge/HTTP/clients/how-to-create-a-HTTP-request/, https://github.com/elaichenkov/odottaa#installation. @symon-skelly would something like this work for your scenarios? Playwright is a high-level API to control and automate headless Chrome (Chromium), Firefox and Webkit. Save my name, email, and website in this browser for the next time I comment. It's quite easy, you just do a fetch inside the function. Example for Playwright: Inside of evaluate you can access the LocalStorage etc. What you need to do is first start waiting for the response and then click, so the waitForResponse () can catch the actual response coming as a result of the click. Im a big fan of being able to call APIs during e2e tests to set up data, verify things, do things and all that jazz. The API may be nice, but can you really do deep assertions on JSON payloads ? That means we need to "catch" the outgoing request and return some static data based on it. By clicking Sign up for GitHub, you agree to our terms of service and Since we actually log in into BigApp, FairyDust gets a new auth token for every test run on CI, and a straight mapping of request URL+headers+body to response headers+body will not work out of the box. With 1.19 version it looks easy. It looks like what you really want is this: https://playwright.dev/docs/auth#reuse-authentication-state. response.finished () Added in: v1.8 returns: < Promise < null | Error > > Waits for this response to finish, returns always null. It enables cross-browser web automation that is ever-green, capable, reliable and fast. IDK bypassing cors was available I am so happy to know such option exists. https://github.com/kousenlsn/playwright-request-mocker. Is it something like incremental session id that the server keeps tracking of? Well occasionally send you account related emails. Maybe the filter/pattern piece already mentioned is the same thing. Finally, upon executing all tests and we should get a pass. Removing external calls for static resources ( images & co ) in Component tests. Sounds like a valid use-case. A QA by profession and a Coder by passion. We get the request from the browser context: request = context.request. Chrome networking stack is different so it has different tls fingerprint. One feature of cypress that really shines in the ability to make HttpRequests using the cy.request() function, I use this many times throughout the current system however the most important request is used to setup my randomly generated user application state before I . @Dospios we are curious to find more out about the use-cases why people use cy.request. Playwright was built similarly to Puppeteer, using its API and so is very different in usage. Remove Selected Files Here, first we are using the setInputFiles command to select the files for upload and then asserting that the intended file was selected successfully. I wish there are really good way to send request. Feel free to contribute or report any issues, it is quite green still. The auth token is in all the API calls FairyDust makes over XHR or webSocket. To isolate it from the actual API we could create the following function: With Node I have to use some mitm proxies setup certs etc which gets tedious. Are we supposed to listen to the requestfailed event and match the urlFilter, to decide wheter to fail the test ? Am still unsure how to handle aborted requests for URLs that match the urlFilter but aren't in the HAR itself. But my goal is to integrate it into a testing framework @codeceptjs so I prefer to wait for a solution by Playwright team. Luckily, Playwright has a built-in method for it - route.fulfill ( [options]). About which of the following cases is this issue, since a few different feature requests are mentioned? One of the main differences with other browser automation tools is that Your email address will not be published. Note from maintainers: request interception and response mocking work in Playwright. Playwright seemed to me a much more flexible tool and I like it more, but at the same time it is more convenient to work with the backend in cypress because of cy.request. I'm interested in reusing code/test cases for multiple types of tests where possible: integration, e2e, regression, visual, etc. @sebinsua -> You can create a custom fixture that override page and check if its a retry or not , https://playwright.dev/docs/test-fixtures#overriding-fixtures, [Feature] Record network requests and save them as ready-to-use mocks, 'data:application/javascript,console.log(1);'. If I have already written a test that checks authorization on the frontend, then for the following tests that require authorization, there is no need to perform authorization on the frontend, it is much more efficient and faster to register accounts and perform authorization on the backend.
