Python Functional Testing

Python is one of the most widely used programming languages along with Java and C. The usage of the Python language is steadily growing and the popularity of test automation frameworks that are based on Python is increasing too. Needless to say, this programming language already comes with a set of tools that can help create automated tests for your application. But while looking for the most suitable framework, developers and testers may be a little bit unsure. It is necessary to take into consideration such things as scripting quality, test case structure and the required technique to test the application modules and identify their defects. Currently, there are 5 excellent Python frameworks to know. The first one is the Robot framework, that can operate well with Windows, MacOS or Linux operating systems. The next one Pytest – open source, quite easy in use, but is meant more for unit testing. Then follows UnitTest or PyUnit – a popular low level test automation framework. Then we have Behave which allows users to compose BDD based tests. The last one is Lettuce – another behavior-driven automation tool. Read the full article

Functional Unit Testing

If you are wondering what unit testing is, let's take a closer look. Unit testing means ensuring that small pieces of code operate correctly in isolation. Unit testing is typically carried out without dependency on any external resources, for example the network or database. Unit tests are not difficult to write, and that is why they are easy to work with. One good advantage of adding unit testing to your work is that it motivates developers to write better code. Why? Should your code be poorly designed, the process of writing unit tests will be more complicated. Performing unit testing is a good way to prevent bugs from occurring repeatedly. When there are issues that come up again and again and you are not sure how to fix them – try unit testing, it specifically tests the problematic condition, and that makes it easier to pinpoint the bug and fix it as soon as possible, should it appear again.
