The world of software development is changing, and most organizations are adopting the fast-paced development approach to arrive early to the market. To align with fast-paced software development automation testing is no longer an option rather it has become a necessity. 

Organizations are adopting continuous integration (CI)/continuous delivery (CD) to reduce the manual effort of the development process. Automation testing perfectly fits into modern DevOps ecosystems and produces the most stable results. 

Automation testing has many different types – frontend testing and backend testing are the most popular. Backend testing involves verifying the backend system (other than the user interface) such as API, Database, third-party library calls, server performance, etc. Though the backend testing seems complicated, the backend automation testing tools make your life easier.

What is backend automation testing?

The backend automation verifies the components behind the application such as the database, Application Programming Interface(API), third-party library calls, etc.

Testing can be broadly divided into two types

Front-end testing focuses on visible elements of the application such as user interface, styles, alignments, borders, and fonts. Further, it also focuses on functionality using the UI. Front-end automation tools help to carry out the front-end testing.

Backend testing focuses on components behind the application such as the database, API, and libraries. Sometimes the backend testing also focuses on application infra and performance. Many backend automation tools can help you automate the backend testing tasks. Unlike front-end testing backend testing may not be straightforward as it requires deep-level technical knowledge not just the application functionality. However, with the help of the right tool, the complexity can be eased.

What do the tools for backend automation testing do?

The front-end testing is conducted on visible elements and workflows, however, backend testing doesn’t contain user elements. Backend testing validates non-UI components such as API calls, Server side tasks database queries, etc. For example, if you need to test the API then you need to send the request with a predefined body and you will get the text, status codes, error codes, etc. as a response hence there will not be any visible components, or styles in the backend testing.

Database testing is another part of backend testing, where the tester executes a set of queries on the database and expects the specific data as a response.  The database testing requires direct connection to the database server and queries will be sent to the connected server.

As mentioned earlier, the database testing also doesn’t involve any user interface, mostly command line tools or programmatic code will be used to carry out verification.

10 Best Backend Automation Testing Tools

As we discussed earlier the backend testing is more complicated than the front-end testing. Without the right tools, it would take a long time to complete the testing, in turn, it can affect the delivery cycle. The backend automation testing tools provide the capability of automation just like front-end automation tools. However not all the automation testing tools support backend testing.

Let’s look at the most popular backend testing tools

Testsigma

Backend testing is the most important part of the testing due to backend system dependency. The backend testing focuses more on the Database, server activity, API and infrastructure, etc. Backend component failure can cause the whole system to be down and in turn it can damage the organization. Testing backend components is more complicated than the front-end components as it doesn’t involve any visible items like UI. Backend testing is non-browser-based testing hence there will not be any browser dependancy so it can be performed programmatically or via command line. 

Leveraging backend automation testing tools helps in swift feedback, and also it aligns with the modern DevOps and agile development framework. Remember, always choose the automation tool after carefully evaluating your requirements and limitations. Most automation tools require programming skills and organizations might have to spend a lot on upskilling resources. However codeless automation tool like Testsigma allows you to write the code in plain English language so even non-technical people can contribute to the backend test automation.
