Automation Testing And Its Types


Automation testing is a software testing method that applies tools and technology to better control test execution, reduce testing effort, and provide faster, lower-cost testing capabilities. It helps in building quality software with minimal effort as it eliminates the need for manual testing.

It is crucial to be aware of the types of automation tests that exist. This gives you a clear idea of ​​the completeness of a test automation program that you can incorporate into your organizational structure. It also helps to make smart decisions, in turn, to achieve optimal results.

Keep reading to take a closer look at the wide variety of automation test types. Here are the most common types of automation tests.

Automation based on:

1. Type of test

Functional test: It tests the business application of the software solution in the real world, evaluating the software against the defined specifications and functional requirements. It mainly focuses on application performance. The main objective of functional testing is to test the main functions of the system such as its accessibility to users, basic usability, etc.

Simply put, this is done to test the business logic that goes into building an application. Automating this means writing scripts that validate expectations of application functionality and business logic.

Uber, for example, is a ridesharing and transportation app. It should be able to connect app users to Uber drivers when all conditions are met. Integration testing, unit testing, smoking testing are examples of functional testing that will be described in more detail.

Nonfunctional :

Non-functional testing defines the testing of non-business elements of an application such as usability, reliability, performance, security, databases, etc.

It differs from functional testing because it focuses on the performance of the application and not how it is supposed to work.

Using Uber as an example, non-functional testing ensures that the application performs efficiently and quickly when performing essential functions, such as connecting end users to drivers.

Common types of non-functional testing are performance testing, regression testing, security testing, etc.

2. Type of tests

Unit tests : It is normally performed in the development phase of an application and is the first type of automated testing performed. Testing an application’s code and coding standards such as how functions and methods are written are the reasons for performing unit testing.

This involves running tests on individual functions or components separately to confirm that they are working as needed.

Unit tests are incredibly beneficial because these tests identify bugs early, thereby reducing the cost of fixing as low as possible. This helps to facilitate code reuse and to understand the functionality of each unit of the application.

Unit testing techniques are divided into three categories:

  • White box testing: tests the application’s functional behavior of the application
  • Black Box Testing: Involves testing UI tests with output and input.
  • Grey-box testing: Involves running test suites, performing risk analyzes and test cases.

Smoke test: It is also known as confidence test and build verification test and it is a common testing method. It includes a small number of test sets that are run multiple times. It is designed to assess the viability and stability performed immediately once the software is developed and functions are integrated into the software build.

This is to ensure the proper functioning of the application. The failure of the test decides whether it should be shelved or returned to the development team for modifications and whether it can continue to other phases of testing.

Integration test: As the name suggests, it involves testing the functionality of the application by integrating all modules and units of the application into the unit. It focuses on the assessment of the compliance of the system as a whole with the functional requirements set for it.

The different modules are grouped and studied according to their interactions with each other. This ensures seamless interaction and smooth operation between the various functions of the software as a whole. Integration testing is done through the application’s UI layer or API testing.

Various approaches to integration testing are used, such as top-down approach, big bang approach, sandwich approach, and bottom-up approach.

Regression tests: Among the most common automation tests is regression testing. The main purpose of regression testing, usually done at the end of a new module test, is to ensure that each existing module is unaffected by the code changes made.

This involves repeating and re-running functional and non-functional tests to verify that the software works as before after a program or code change has been made. The software will have “regressed” if the performance is not the same. All test teams automate this pack because it is run frequently.

Safety tests: Involves requests for susceptibilities. Functional testing will include permissions and such, and non-functional requirement testing for cross-site scripting, SQL injection, etc.

Performance testing and quality control:

These are non-functional tests targeting requirements such as load testing, application scalability, stress, etc.

Hopefully, this article’s brief overview of automation and its different types has given you a better understanding of the types of test automation.
