Everyone knows how important it is to test the web applications and services developed regularly, and fortunately, all perform it. But can they really manage? One simple Java program can behave in many different ways. Some of them occur only in a partly uncommon scenario. Suppose testing was done of every possible behaviour, and at the initial release, the web application was validated. Then what about the second release? Or even a “minor” change in the main code?
The added or modified changes will be tested. But what about others that are unrelated? There are features that can be broken by minor changes that we have to consider. And for all that, the answer is… Automated Testing.
In automated testing principle, the program is written in Java and run in the web application or a website feeding it the proper input and checking the output against the expected. Once the automated test suite is written, it requires minimum human intervention to analyze the result and to run the web application. Our automated test suite does it all and shows the successful and failed tests.
For example, let’s say we are testing a form. Forms are an essential part of any website and a supreme means to assess your business. They are used to involve users, provide an endorsement, sell products and services, etc.
A poorly designed form or one that was badly tested can and will prevent your visitors from leaving with a bitter image of your company. And without a doubt, you don’t want that 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 go under a battery of automated tests to check if all works as it should under every circumstances and inputs.
Why Automated Testing?
Save Time and Money
Writing automated test scripts does take time and effort, but we don’t need to invest more than necessary. People are not willing to write automated test scripts as test automation in Java looks like a luxury. The creation of an automated test suite should be counted as an investment and risk removal tool for application testing. And after a time duration into a project, the cost is paid off not only for building an automated test script to find defects but also by saving a lot of testing time.
It’s just a piece of cake to execute an already written automated test script than to perform it manually, even small corresponding test cases, especially if they require a complicated setup. The program finally works after the web application testing is performed. Charges for creating an automated test suite can be paid before the application is even released.
A set of automated test scripts has a longer lifespan than the source code. A program can be re-written in another language and can also be re-designed. The test suite will work even if it has to perform the previous test. Since the cost of the up-front writing of automated test scripts is recovered, the final pay-off can surprise you.
Testing Coverage is Expanded in Automated Web Testing
The depth and scope of tests to help improve web application quality are being increased through Automated web testing. During manual testing, long and more complex application testing is avoided and can also be performed with no human intervention. Python’s automated test scripts can easily run thousands of complex test cases providing incredible coverage that could take years with manual testing.
These test scripts help free up the time of testers engaged in repetitive manual tests who can create new automated test scripts and deal with more complex features. The largest team of the QA can’t simulate even a hundred users simultaneously browsing the website.
Python, as the major scripting language of automated testing, can recreate tens, hundreds, or thousands of viewers interacting with web services and applications or with networks which improves the quality of the application.
Tools used in Test Automation
Robot framework is known as a next-generation test automation that leverages the power of open and stretchable architecture, designed for ATDD (Acceptance Test Driven Development) and acceptance testing. Our team uses it with the Selenium library, a robot framework test library that uses the Selenium web testing tool internally, for maximum coverage.
For cross-browser testing, Selenium is used with–
- Selenium IDE
- Selenium WebDriver
For real-time graphics processing, OpenCV is widely used. It allows 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 can simulate keyboard and mouse use and manipulate windows.
