Selenium webdriverjs detect file download example

Also, JavaScript is far from preferred language for many teams, and if you have few thousands test written and maintained for your application in different language, there is little value of throwing it all out of the window and start with JavaScript. For team starting on a green field, limiting to single language for both GUI development and automated tests might make sense, but for legacy projects - not so much. And Python is also excellent language superior to JavaScript, IMHO to automate text parsing, system administration etc, which are important part of test automation.

I do not see benefits of switching all these tasks to JavaScript. JavaScript is slowly improving, and it is likely here to stay for GUI development for a long time, but Python is likely the closest language to the one programmers will be using years from now: read The Hundred Year Language by Paul Graham who coined the term "blub paradox" - btw this article is promoting Lisp, not Python, but also worth a read. I am not rejecting promises it is a clever concept and very useful for even-driven programming , but reliability of automated tests requires different concepts, like data-driven programming.

Our GUI developers are creating some unit tests in Protractor, but we feel that Python is better fit for most of the other test automation tasks. Another aspect: duplication of effort is acceptable if quality is extra important , like in aviation: many aviation components use two sets of processor, from different manufacturers and programmed by two different teams in two different languages, to detect subtle misunderstanding in requirements, undetected errors in CPU, interfaces, etc.

In such situation, using different language for testing would be not just an option, but a requirement. I hope nuclear power stations are handled like this too, but have no personal experiences with it Documentation and number of answered questions on sites like stackoverflow. Languages like Java give much better search results. Yes, but not per se a positive one. It adds an extra complexity to coding that most test engineers do not have a good understanding of, although this is getting better due to the increased use of modern JS frameworks in teams.

To handle the new complexity the WebDriverJS team added a promise manager, which they are now going to remove in the near future. Personally I think a procedural flow for tests is fine and maybe even better, because it is easier to grasp. Just like Peter described in his answer. Users do not do their actions async on a website.

Finally, the login button is clicked. The implementation of both methods — executeScript and executeAsyncScript is a perfect solution that efficiently solves the problem of any potential issues. Selenium is an open source automation testing tool that supports a number of scripting languages like C , Java, Perl, Ruby, JavaScript, etc.

Protractor and Selenium For starters, Protractor is a Node. Protractor and Jasmine And what about Jasmine? In summary, these are the pieces involved in Protractor testing: Protractor. The necessary binary will get installed when we install Protractor. This is a Node. Also a Node. Jasmine , or a different test framework, such as Mocha. Selenium Server. Chrome , or another one of the supported browsers.

End to End Testing: What It Is and Why it Matters End-to-end testing is a testing technique that exercises an application in its entirety, verifying whether its flow, from beginning to end, behaves as expected. Why Use Protractor? Protractor: The Good and the Bad There is no such thing as a silver bullet in software development. Benefits Realistic testing. End-to-end testing is very close to how a real user interacts with the application. It can provide feedback that no other type of software testing can.

Protractor is an open-source tool. Interested users can see how the project evolves, and even happen with such development. Well-suited for Angular. Though you can use Protractor to test non-Angular JavaScript apps, the tool obviously targets Angular apps. It can use strategies that result in more robust tests.

Easily installation and setup. Protractor is a Node. As such, you can install it via npm and get it ready to use very quickly. WebdriverIO provides a Node package for testing with web driver. To test your application without rebuilding Electron, simply place your app source into Electron's resource directory. Alternatively, pass an argument to run with your electron binary that points to your app's folder. This eliminates the need to copy-paste your app into Electron's resource directory.
