I solved my problem. In fact my docker container (frontend) is called "app" which is also domain name of fronend application. My application is running locally on http. Chromium and geko drivers force httpS connection for some domain names one of which is "app". So i have to change name for my docker container wich contains frontend application.

The sky’s the limit (and even beyond that) when you want to run test automation. Technology has developed so much that you can reduce time and stay more productive than you used to 10 years ago. You needn’t put up with the limitations brought to you by Selenium if that’s your go-to automation testing tool. Instead, you can pick from various test automation frameworks and tools to write effective test cases and run them successfully.
When it comes to web automation testing, there are a number of frameworks like Selenium, Cypress, PlayWright, Puppeteer, etc., that make it to the ‘preferred list’ of frameworks. The choice of test automation framework depends on a range of parameters like type, complexity, scale, along with the framework expertise available within the team. However, it’s no surprise that Selenium is still the most preferred framework among developers and QAs.
Playwright is a framework that I’ve always heard great things about but never had a chance to pick up until earlier this year. And since then, it’s become one of my favorite test automation frameworks to use when building a new automation project. It’s easy to set up, feature-packed, and one of the fastest, most reliable frameworks I’ve worked with.
The speed at which tests are executed and the “dearth of smartness” in testing are the two major problems developers and testers encounter.
With the rapidly evolving technology due to its ever-increasing demand in today’s world, Digital Security has become a major concern for the Software Industry. There are various ways through which Digital Security can be achieved, Captcha being one of them.Captcha is easy for humans to solve but hard for “bots” and other malicious software to figure out. However, Captcha has always been tricky for the testers to automate, as many of them don’t know how to handle captcha in Selenium or using any other test automation framework.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
