Testing is an important process in software development. As you may know, software development comes with its fair share of issues and bugs and the only way to detect those bugs is through testing. In fact, many organizations take software testing as important as the product development itself. The reason is simply: when you do not test your product properly, you are bound to deploy bad products to production. This translates to poor customer satisfaction and in the end, low revenue.
Why is using Frameworks Important?
The process of software testing is however a herculean task when done manually. Software testers now use frameworks that create a standard guideline for code standardization, object repositories, result storage, and many more. Generally speaking, these frameworks help with automation software testing. In the end, you get faster deployment, more homogeneity amongst developers, faster issues resolution, and a reduced overhead cost.
While Java is known to be one popular language for software automation, Python also has a handful of frameworks that make test automation easier. In this article, we will discuss popular Python frameworks you can use for test automation today.
Meanwhile, Python is a powerful multipurpose language used in many real-life applications. To learn more about how to use this popular language, check for the best online python courses and get Python certification. You stand a better chance of landing a Python job.
That said. Let’s jump into the article.
1. Pytest Framework
Pytest is one of the most used automation frameworks; the reason being that it works with various programming languages. Pytest is less bulky. Its concise nature allows you to focus primarily on building test cases without distractions.
Due to its small size, it is less complicated and can be learned easily. Also, Pytest gives robust information such that there can be any failed test, making it easier for the tester to figure out the result. Basically, this should be your go-to tool for less sophistical projects.
- It is a quick and easy tool for creating test cases and debugging
- It allows compact test suites.
- Test cases written in PyTest cannot be used in another testing framework.
Lettuce can be seen as an amalgamation of Python and Cucumber. Like in Cucumber, it uses Behaviour Driven Development (BDD) approach for testing. Generally speaking, BDD approach is easy to comprehend even by a non-technical person. It is however recommended for simple and common tasks as those are the scenarios where it shines.
- Since it is easy to read, there is better collaboration between QA teams and testers.
- Creating test scripts is less complicated.
- Because it uses the BDD approach, there is a need for consistent communication between testers and other stakeholders. A lack of communication can lead to ambiguity and later, confusion.
This is great automation testing in Python. Interestingly, you can use the Robot framework to test other applications such as MongoDB, FTP, Android, Appium, and so on.
Robot makes use of a keyword-driven approach, making it easy for test cases to be created and read. Robot is open-source and has cross-platform support. In other words, it can be used in Mac, Windows, and Linux OS. Robot has a lot of libraries that make it easier to use, yet advanced. There is also an API extension that further simplifies the process of automation testing.
- It uses the keyword-driven approach. Hence, test cases are extremely readable.
- Parallel testing can be done using Selenium grid
- It has several libraries and APIs that make testing much easier.
- It may not be the best option for complication codes as customer test codes need to be written.
- It cannot be used for testing conditional statements and nested loops.
Behave has a strong correlation with the Cucumber framework, only that it is based on Python. It uses Behavior Driven Development (BDD) approach for testing. You can also write fast, easy, and readable test cases in Behave. It is a generally great option if you want to work with other team members such as the QA team, developers, and other stakeholders.
- Test cases are written almost like plain English, making it simple to create.
- A non-technical person can read test codes and understand. This is why Behave is recommended for collaboration work.
- It is only suitable for black-box testing. You literally cannot use Behave to check the inner workings of the tests or specific reasons why the test failed.
Selenium is an open-source and popular automation testing tool. It can be used alongside various programming languages including Java. Selenium also does seamless website interaction with no human input. Over the years, Selenium has grown to become the least and perhaps sufficient requirement for most browser-based automation testing roles.
- It is popular with a vibrant community.
- It is open-source with active development by the maintenance.
- It can be used for powerful web-based software testing.
- Selenium can only be used for testing web-based applications
- It is relatively more difficult to use, especially for a newbie.
- Its syntax is simple and easy to read
- Parallel testing can be done, i.e. from both the client-side and the server-side at the same time.
- It allows asynchronous and DOMeless test cases.
- Jasmine does not support DOM test cases.
