Everyone recognizes the need of testing on a regular basis of web applications or services created, and hopefully, everyone does it. But do they truly succeed? Even a simple Python-written program can react in a variety of ways, some of which occur only in a rare and difficult to arrange scenario. Assume that before the initial release, every potential action was tested and the web application was validated. What about the next release, or even a "minor" change in the source code? The new or changed feature will undoubtedly be evaluated, but what about other, seemingly unconnected at first, features that could have been irreversibly broken by that tiny improvement? And the answer is Automated Testing.

The Automated Testing principle is that there is a program that runs the web application, website feeding it the proper input, and checking the output against the expected. Once the automated test suite is written, no manual intervention is required to run the web application or analyze the results; the automated test suite does it all and shows (via a message and a results file, for example) which tests passed and which failed.

Let's look at a real-world example, such as form testing. Forms are a vital component of every website and a great tool to assess your company's performance. They are used to communicate with users, give support, and sell products or services, among other things. A poorly designed or poorly tested form can and will frustrate your clients, leaving them with a negative experience of your service. You don't want such a reply from, say, a payment or order form. To avoid this, after the form has been visually validated, it must go through a series of automated tests to guarantee that everything works properly under all conditions and inputs. 

Web testing on automatic basis saves time and money

Although we should be willing to invest time and effort in creating automated test scripts, there is no incentive to devote more than is necessary. Actually, because test automation may appear to be a luxury at first, and as a result, many are hesitant to write automated test scripts, developing automated test suites for application testing should be viewed as both an investment and a risk-prevention tool. And, just a few months into a project, the expenses of developing automated test scripts are offset not only by the detection of hidden issues, but also by the fact that test scripts, once produced, save a significant amount of testing time.

It's far easier to run an already-written automated test script than it is to perform even a small number of corresponding test cases manually, especially if they require a complex set-up. Because web application testing will need to be performed several times before the program is fully functional, money spent on developing an automated test suite, assuming it was written alongside the code, or even earlier can be repaid before the application is even released. Furthermore, a collection of automated test scripts has a longer lifespan than source code. A program can be redesigned, even rewritten in a different language, and the test suite will still work as well as it did before. Once the initial expenditures of developing automated test scripts have been recouped, the pay-offs can pleasantly surprise you.

Automated web testing extends the coverage of testing

Automated web testing expands the breadth and depth of tests to aid in the improvement of web application quality. Longer and more complex application testing, which is frequently avoided during manual testing, can be completed without the need for human intervention. Automated web test scripts written in Python can run thousands of different complex test cases each time, providing unimaginable coverage that would take years to achieve with manual testing. Testers who are no longer subjected to repetitive manual tests have more time to develop new automated test scripts and deal with more complex features. Furthermore, even the largest QA team cannot simulate a hundred users browsing the website at the same time. Using Python as the primary scripting language, automated testing can simulate tens, hundreds, or thousands of viewers interacting with network or online services and applications, thereby improving application quality.
