Test Automation Frameworks

A test automation framework is a collection of best practices for creating reliable test scripts. A framework is a set of policies and programs designed to help quality assurance professionals run tests more rapidly and effectively. Coding standards, methods for handling test data, object repositories, processes for saving test findings, and how to go to external resources could all be part of the framework’s rules.

Even if testers don’t follow these guidelines when creating or recording tests, they can still do so. Although embracing a structured approach brings with it additional benefits. Therefore, a better software product can be achieved through the use of an efficient automation testing framework by facilitating the early detection of errors and decreasing the amount of time spent on manual testing.

Data-Driven Automation Testing Framework

As a result of the separation between the test data and the script logic provided by a data-driven testing framework, testers are free to store test data. Testers may find themselves in a situation in which they are required to perform tests on a particular attribute or functionality of an application over and over using unique sets of data. 

Additionally, because this testing framework eliminates the need for hard-coded scripts for the test data, the process becomes much simpler.

Testers are able to save input and output parameters from an external data source in a data-driven test framework, and then pass those parameters to test scripts. Examples of external data sources include Excel spreadsheets, text files, CSV files, SQL tables, and ODBC repositories.


  • A quick pace for the test.
  • Extremely scalable.
  • Better flexibility
  • Fewer test scripts are required.


  • An extended period of time is required for setting up
  • It is necessary to have advanced technological expertise.
  • The process of troubleshooting is laborious.

Linear Automation Testing Framework

In contrast to the method described above, linear scripting is carried out by hand by a single individual, who then painstakingly documents each stage of the technique. It is more frequently referred to as the “record and playback” framework, and its operation takes a significant amount of time.

Even if it is a straightforward method for recording and does not call for expertise in automation, it does not make it possible to reuse scripts. The process of maintaining the framework would take more time because you would need to manually create the test script in the future in order to execute the framework.


  • Clarity
  • Quickness and ease of operation
  • Extremely adaptable


  • Need for increased maintenance
  • Additional redundancy
  • Single-use

Keyword-Driven Testing Framework

The data-driven testing framework has an extension known as the keyword-driven testing framework. This framework copies your test data to an outside source and safely stores the codes. These codes, which are sometimes referred to as “keywords,” have the ability to alter the script for the test and draw additional conclusions based on the test framework.

In addition, the use of these phrases is what effectively determines the duties that are carried out by each program.


  • Enhanced potential for reuse
  • Simple in terms of upkeep
  • More scalable


  • The level of complexity grows as time passes.
  • Long period of time for development.
  • Demands an in-depth understanding of automation testing.

Hybrid Testing Framework

As is the case with the majority of testing techniques used today, automation testing frameworks have started to blend and overlap with one another. A hybrid framework is one that combines two or more of the aforementioned frameworks to make use of each one’s benefits while minimizing the negative aspects of the others.

Because each application is different, the testing methodologies used for it should also be distinct. As more teams adopt an agile methodology, it is imperative to put in place a testing infrastructure that is both adaptable and automated. Having a hybrid framework is essential if you want to get the best possible results from your tests. Job opportunities for software testers are numerous. Grab yours by registering for SLA’s Software Testing Training in Chennai.


  • The rapid rate of test execution

  • A reduction in expenses


  • Extremely difficult, which means that a high level of technical expertise is required.
  • Tests must be completely programmed in order to pass.

Library Architecture Testing Framework

It is possible for testers to group similar activities according to the function that is stored in a library if the framework for testing the library architecture detects tasks inside each test script that has features in common with one another. Because of this, it is now much simpler to reuse code across several different test scripts. 

This framework is helpful in situations in which distinct application components have functionalities that are comparable to one another.


  • A high degree of reusability
  • Cost-effective
  • Enhancement of the ability to scale
  • High ROI over the long haul 


  • More development time Complex
  • It is necessary that you have extensive technical knowledge.
