Sometimes manual methods of testing the software would be a cumbersome task to carry out. However, Gone are those days when you have to rely on a manual way of testing the software. At present, you can automate tests whenever you want from anywhere in this world with no trouble.
To leverage the power of automation, you need to have a stellar test automation framework deployed in the testing process.
What is a test automation framework?
Test automation framework is a comprises tools, guidelines, resources, and rules required to bring automation to the testing process. They will be located in a single place so that you do not have to spend time looking for them.
For instance, imagine that you are at an airplane ticket counter. The ticket counter also serves as a place to get answers to your queries, get the boarding pass, etc. A lot of services at one place! Sounds good right?
Likewise, the test automation framework provides all the necessary information and resources you need to execute the test cases in one place.
Test automation framework can prepare test cases based on the latest circumstances by providing syntaxes, methodology, preparing testing iteration, etc. so that testing can commence easily.
Different Components in the Test Automation Framework
API: Be it RestAssured API, Selenium, Driver API, Selenide, WinApp, etc., or any API. There has to be an automation API for the framework to work
Test data management: Test data can be stored in a separate file so that, to modify it you need not modify the script. All you have to do is access the data and modify it accordingly. And also, there should a robust library that can be used to scavenge the heap of production data to find the one suitable and safe for testing
Efficient Libraries: The success of the automation framework depends upon the arrangement of test cases. For that, you need libraries to store and manage effortlessly.
Testing tool: An array of tools is required to run the test automation framework. Defect tracking, traffic generation, analysis, requirement analysis, etc. require a separate tool.
Page object classes: This component helps in the reusability of tests. Duplicating all the functions in every test is a daunting task. A page object model or an API will help in reusing the page classes in multiple test classes to change one place
CI integration: For better ROI the tool must be able to integrate with the continuous platform so that once new code is injected into the software system automated regression tests can be facilitated.
Report Generation module: The framework wil be equipped with different kinds of libraries that can generate reports based on the requirement
Types of Test Automation Framework
Modular Test Automation Framework
In this type of framework, the application that will be subjected to testing has to be divided into modules. Scripts will be written for each module and tests will be executed hierarchically.
To achieve ease of access, there will be a master script that can be used to evoke scripts for each module.
The biggest advantage of the module test automation framework is that you only need to alter the script of a particular module.
Reusability is another advantage of this type of test automation framework. However, there are a few disadvantages as well. Adding multiple data sets is impossible as data is hardcoded to the script and writing the script required coding knowledge.
Linear scripting framework
This is a basic level of framework and is often called a record playback framework.
The linear scripting framework works linearly and thus the name.
This type of framework is majorly deployed to take care of the testing activities of small applications.
The scripts in this framework are not structured and for the same reason, they can interact directly with the application under test.
Owing to the same, you can generate tests very easily.
Since the tests are in sequential order, the Linear test automation framework is the fastest available at present.
However, there are disadvantages to this platform. They are, lack of reusability of the scripts, hardcoded data sets, and maintenance.
Data-driven Test Automation Framework
In this type of test automation framework test data and script logic will be separated from each other. This helps in adding different data types to every test.
Data is often stored in the form of XML, spreadsheets, MS access tables, text files, CSV files, SQL databases, etc.
Since data can be changed easily, multiple scenarios with varied data inputs can be used for testing. As a result, a lot of time can be saved, increased test coverage, flexibility in test execution, and many more.
Even though the perks are plenty there are certain drawbacks to this framework as well. You need to have an experienced tester with coding skills to take care of this test automation framework.
And also, testing up a data-driven test automation framework is a daunting task.
Keyword-driven test automation framework
This type of framework relies on tables or words for tracking tests.
Keyword-driven testing is also known as action word-based testing and table-driven testing owing to the reason mentioned above.
Every functionality of the application will be laid out in a table accompanied by instructions that are required to run the test. Often testers have to test the same functionality multiple times with different data sets.
Since data changes often it cannot be hardcoded to the script. In this kind of scenario, keywords can be of great help to testers or anyone else who runs the test.
Advantages of keyword-driven test automation include provision for the addition of multiple data sets, the ability to test multiple scenarios, and also several scripts that can be reduced in number.
Hybrid testing framework
Testing scene changes based on the application under test or the company strategy.
Implementing a hybrid testing framework requires deep testing knowledge because, as the name suggests this is a combination of multiple testing frameworks so the complexity involved in the operation is very high.
The idea behind the hybrid testing framework is to leverage the advantages of multiple frameworks in one single testing scene.
Since this framework is a combination of multiple flameworks its operability can be set to flexible or rigid based on the tests.
Hybrid testing frameworks are mostly opted for by software development companies who are releasing software frequently.
Top 10 Test Automation Framework Tools
16 years have passed since the birth of Selenium. This exemplary tool has helped in the testing of bazillion web applications across the world. There are 3 major components of selenium they are.

The best way to choose the right cross of test automation from the ones listed above is to have a clear idea about the process and to ask certain questions.
Do the testers in your company have coding knowledge? If the answer is yes you need a platform that can be used by employees who have coding knowledge and ones who do not have a coding background.
Another thing to consider is the platform the software is built on and whether the framework can efficiently test it?
Most importantly, money matters! No matter what, pick a tool that’s in your budget.
