Everyone knows how grave it is to test the web application or service you develop on a regular basis, and, with luck, everyone actually does perform it.  But do they really manage? Even a simple program, written in Python can behave in many different ways,  some of which occur solely in a rather uncommon (and hard to stage) scenario. Let's imagine every possible behavior was tested and the web application was validated upon initial release, what about the second release, or even a "slight" modification in the source code? The feature being added or modified will surely be tested,  but what about other, seemingly unrelated at first,  features that could have been irrevocably broken by that minor improvement? And the answer is …. automated testing.


Automated testingThe principle of automated testing is that there is a program that runs the web application, written in Python or a website feeding it the proper input, and checking the output against the expected. Once the automated test suite is written, minimum human intervention is needed,  neither to run the web application, nor to analyze the result;  the automated test suite does it all,  and shows (say, by a  message and a results file) which tests succeeded and which failed.

Let's switch for a moment to some example - testing a  form.  Forms are an integral part of any website and an excellent means to assess your business.  They are used to engage users, provide support, sell products and services, etc. A badly designed form or one that was poorly tested can and will frustrate your visitors into leaving with a bitter after the image of your company. And you definitely don’t want such a reaction from, say, payment or order form. To prevent this from ever happening, once the visual check of the form is done,  your form must undergo a battery of automated tests to check if everything works as it should under any circumstances and inputs.



Even though we should be willing to invest time and effort into writing automated test scripts, there's no reason to invest more than we have to. Actually,  because test automation in Python might seem at first like such a luxury, and people are therefore not willing to write automated test scripts, creating automated test suites for application testing should be considered as an investment and a risk prevention tool. And just after a few months into a project,  the costs of building automated test scripts are paid off not just by detecting hidden defects, but also by the fact that test scripts, once written, save a lot of testing time. It's so much easier to execute an already-written automated test script than to perform manually even a tiny bit of corresponding test cases, especially if they require a complicated set-up. Since web application testing will actually have to be performed a few times before the program finally works,  money spent on creating an automated test suite  (assuming that it's been written along with the code, or even earlier)  can be repaid before the application is even released. Also, a set of automated test scripts tends to have a longer lifespan than the source code. A program can be redesigned -- even re-written in another language -- and, assuming that it was meant to perform the same as before, the test suite will work just as well. Once the up-front costs of writing automated test scripts have been recouped, the pay-offs can pleasantly surprise you.


Automated web testing increases the depth and scope of tests to help improve web application quality. Long and more complex application testing that is often avoided during manual testing can be performed with no human intervention. Automated web test scripts, written in Python each time can easily run thousands of different complex test cases providing unimaginable coverage that could take years with manual testing. Testers freed from repetitive manual tests have more time to create new automated test scripts and deal with more complex features.

Furthermore, even the largest QA team cannot simulate even a hundred users simultaneously browsing the website. Automated testing with Python as major scripting language can recreate tens, hundreds or thousands of viewers interacting with network or web services and applications, thus boosting the quality of an application.


Quintagroup Quality Engineers are well-versed in both commercial and open-source test automation tools.  We strongly believe that Python web application development is incomplete without thorough automated testing to ensure a sound platform for future reliability. That is why we implement data and keyword-driven automated test scripts, written in Python using a robust Robot framework, Selenium, and OpenCV.

Test Automation Tools

Cypress is an automated frontend testing tool that is used for unit testing, integration testing, and end-to-end testing. It was created to reduce the pain points QA engineers and developers come across when testing applications. Cypress has a BDD/TDD assertion library and a browser that may be matched with any JavaScript testing framework. An interesting feature of this tool is that it doesn't use Selenium. Instead, it sends remote commands via the network while Cypress performs in the same run loop as your app. 

Robot Framework is a next-generation test automation framework that leverages the power of open and extensible architecture, designed for acceptance testing and acceptance test-driven development (ATDD). For maximum coverage, our team uses it together with SeleniumLibrary —a Robot Framework test library that uses the Selenium web testing tool internally.

To provide cross-browser testing, Selenium is used with:

  • Selenium IDE for  scripting quick bug reproduction tests and automated exploratory testing
  • Selenium WebDriver to create complex  regression automation test scripts,  while driving the browser natively as a user would

OpenCV is widely used for real-time graphics processing. It allows performing a complete check of all the graphical content, including videos, motion graphics, 3D, etc.

py.test is a full-featured testing tool written in Python. This framework can be used for both simple unit and complex functional testing.

With the Xaut Python library, we are able to simulate keyboard and mouse use, as well as manipulate windows.
