You don't have to know how to shut down browser, handle StaleElement exceptions and timeouts, or search for relevant log lines when debugging your tests. Selenide is so easy that you don’t need to read a lot of documentation. Selenium WebDriver can be a great tool but it is not a tool for testing. It is a tool for browser manipulation. Selenium WebDriver has many testing libraries. However, they don't seem to address the main issues of UI testing. Instabilities of tests due to dynamic content, JavaScript and Ajax, as well as timeouts, etc. Selenide was designed to solve these problems. Selenide is a stable test solution that resolves (almost all) Ajax/timing problems.

Puppeteer can do most of the things you can do in the browser. Puppeteer core is a lightweight version Puppeteer that can be used to launch an existing browser or to connect to a remote one. Make sure the puppeteer-core version you install is compatible to the browser you want to connect to. People who have used other browser testing frameworks will be familiar with Puppeteer. You create a Browser instance, open pages, then use Puppeteer's API to manipulate them. Puppeteer automatically downloads and uses a particular version of Chromium to ensure that its API works right out of the box. When creating a Browser instance, pass the executable's path to Puppeteer.

Playwright supports all modern rendering engines, including Chromium and WebKit. You can test on Windows, Linux, or macOS. Playwright waits for the elements to become actionable before he can take any actions. It also offers a wealth of introspection events. Combining the two reduces artificial timeouts, which is the main cause of flaky tests. Playwright assertions were created for the dynamic web. Checks are automatically retried until all conditions are met. To eliminate flaky bits, configure test retry strategy, capture execution trace and screenshots. Browsers can run web content from different origins in different ways. Playwright is compatible with modern browser architectures and runs tests out of-process. Playwright is free from the limitations of in-process test runners.

Karate is the only open source tool that combines API test automation, mocks and performance-testing into a single framework. Cucumber's BDD syntax is language-neutral, making it easy for non-programmers. You can run parallel tests for speed and have assertions and HTML reports built-in. For teams that are not familiar with Java, there is a standalone executable that can be run on any platform. You don't need to compile code. You can simply write tests in a simple and readable syntax - designed for HTTP, JSON GraphQL, XML, and GraphQL. You can also mix UI and API test automation in the same test script. It is worth noting that JSON is a first-class citizen' syntax. This means that you can express your payload and expected data without using double-quotes. You also don't have to include JSON field names within quotes. You don't need to 'escape" characters as you would in Java or other programming languages.

Run UI, performance, and unit tests on your Xcode project. You can use the XCTest framework for unit testing your Xcode projects. These tests integrate seamlessly into Xcode's test workflow. Tests verify that certain conditions are met during code execution and report failures (with optional messages), if they aren't. To validate user interaction flows, tests can interact with the UI of an application to measure code performance. A test method is a small and self-contained method that tests one part of your code. A test case is a collection of related test methods. To confirm that your code works as expected, add test cases and test method to a test target. This class is the primary one for testing, defining and executing test methods. A base class that can be used to create, manage, and execute tests.
