Customers currently demand high-quality software for their enterprises and personal use. Software businesses are implementing Continuous Testing procedures to meet this need, ensuring that the software t/hey deliver to the market can outperform the competition.

What is Continuous Testing?

Continuous Testing is an end-to-end automated testing solution that can be integrated into an existing development process. It has the potential to reduce errors and facilitate consistency throughout the development life cycle. It's also the most effective technique to enhance speed and support continuous integration and delivery (CI/CD) pipelines.

Types of Continuous Testing

Unit tests

Unit tests are low-level tests performed close to the application's source code. Individual methods and functions of your software's classes, components, and modules are tested. Automating unit tests is often inexpensive, and a continuous integration server can execute them quickly.

Integration tests

Integration tests ensure that your application's various components and services are compatible. It could be as simple as verifying the database's interaction or ensuring that microservices interact as planned. Because they require various application portions to be up and running, these tests are more expensive to conduct.

API Testing

API Testing is a type of software test that demonstrates Application Programming Interfaces. API testing ensures that programming endpoints are functional, dependable, fast, and secure. API Testing, as opposed to traditional user inputs and outputs, employs software to make API calls, obtain information, and record the response of a system. API tests differ from GUI tests in that they do not focus on the look and feel of a programme. It focuses more on the organization logic layer of software architecture.

System Testing

System testing validates the entire and fully integrated software product. A system test is used to examine the end-to-end system specifications. Typically, the software is just one component of a more extensive computer-based system. Finally, the software is linked to other software/hardware systems. System testing is a collection of various tests whose single objective is to put the entire computer-based system through its paces.

What are the best Continuous Testing Tools?


Selenium is an open-source software testing tool. It supports all the leading browsers like Firefox, Chrome, IE, and Safari. Selenium WebDriver is used to automate web application testing.


Appium is a mobile testing framework similar to Selenium. It's a well-known mobile testing framework that many teams have used.


Kobiton makes Continuous Testing and Mobile/IoT DevOps a reality.

Continuous Testing and agility

Continuous Testing is the technique of running automated tests as part of the software delivery pipeline to quickly get feedback on the business risks associated with a software release candidate. It improves and expands test automation to keep up with the complexity and speed of current application development and delivery. All software providers should use Agile as their delivery model. True agility refers to an organization's ability to quickly shift emphasis and respond to consumer input or market developments. It also allows teams to experiment with new ideas and solutions. Continuous Testing facilitates this agility by promoting a shift-left approach that emphasizes the usage of test automation early in the development cycle. Shifting to the left creates a continual feedback loop, allowing teams to respond to issues and improve team communication.

Why Continuous Testing is necessary?

Continuous Testing improves the initial authorization of software faults and problems. As defects are identified early, the company's costs are lowered. A good testing strategy at the start of the manufacturing process allows for speedier recovery of unanticipated errors or bugs in the product. Continuous delivery necessitates continuous Testing, which can only be accomplished through test automation. The use of automation technologies reduces the amount of time spent on Testing. Automation tools help the testing team and the whole product development focus on Continuous Development.

Continuous testing framework

The term "continuous testing" refers to a collection of development tasks, methods, and technologies. It is impossible to create a one-size-fits-all continuous testing architecture for any technical organization. However, you may identify the essential components of any continuous testing framework and then determine how they relate to your specific situation.

Continuous Integration

CI stands for continuous integration, a software development method in which developers submit code to a shared repository daily or multiple-times-a-day basis. On the other hand, automated build testing is an essential aspect of continuous integration since DevOps-minded teams need to detect problems and bugs in code before it goes into production.

Unit Testing

Individual units of source code, sets of one or more computer program modules, associated control data, and actions are checked to determine suitability for unit testing. Unit test is designed to perform the test on each unit of the software code. Save money and time in the early stages of the development lifecycle can be done by Unit testing.

Performance testing

Performance testing is carried out and provides information to clients about their application's efficiency, reliability, and scalability. It's typically used to track a product's or feature's speed, dependability, and total uptime. On the other hand, software performance testing is critical because it's one of the best ways to figure out how your customers will react to your service. Furthermore, performance testing is frequently carried out in staging and production settings, allowing you to spot earlier issues.

Integration and Functional Testing

In the sense that you are testing individual components of a system, integration testing is comparable to unit testing. On the other hand, integration testing merges these separate pieces into a group that can be tested together. This type of Testing will identify potential failure points and weaknesses amongst integrated pieces, ideally before they are put into production. This is frequently associated with functional Testing, in which pieces of a system are verified against the system's requirements, expectations, and specifications. Businesses need functional Testing because they need to know precisely how a system should behave and whether it responds correctly and consistently, especially in production.

End-to-End Testing

Software engineers may frequently do end-to-end tests to verify that data or workflows travel through an application or service. End-to-end Testing is critical for a product's overall reliability. On the other hand, End-to-end Testing will rarely benefit you in determining the precise source of a mistake or incident; instead, it will simply inform you that something is wrong.

Acceptance testing

Acceptance testing will be the last test you perform before releasing a feature or service to production. The core purpose of this Testing is to check the business requirements and system's functionality, whether it is correct for delivery or not.

Smoke testing

Smoke testing plays a vital role in software development, in which the DevOps organization has to figure out the critical elements of a system and then start testing them. Customers will benefit from a high level of reliability if the most crucial processes and operations inside an application or service are continuously tested.

Chaos testing

"Chaos testing is all about", Creating a state of chaos in your staging and production settings to see how a system reacts to unknown circumstances and stress. Chaos testing regularly might help you identify issues in your infrastructure and apps that you may not be aware of. Conducting stress tests in advance and incorporating chaotic engineering as a regular practice can also better-prepared engineers for real-world issues in your production environments.


Continuous Testing involves automating any or all of the tests outlined above. Otherwise, you'll spend all of your time recruiting new QA engineers, who will spend their time manually testing the overall system rather than developing new functionality for customers. It's important to remember that automated continuous Testing must be beneficial to everyone involved with your products — your consumers and your employees.

Continuous delivery

Continuous Testing requires consistent delivery. We will deploy to production more frequently and with fewer defects, if you know that code works as quickly as it's continually integrated into a shared repository. You may start delivering value to clients daily with more automated Testing and a commitment to continuous manual Testing throughout the software development and release lifecycle.

How is Continuous Testing done?

Developers develop code, commit it, and store it in version control/SCM. This is the initial step in DevOps. It keeps track of the code that developers create. The following stage is Continuous Integration. Rather than waiting for all developers to contribute code before building and testing it, the code under a Continuous Integration approach is merged into the main branch. Then generate a build with Jenkins/Git and test the code in a virtualized environment. It saves a lot of time by allowing you to move code from development to Testing without waiting for all developers to commit it.

Continuous integration is useless unless it is accompanied by continuous Testing. The next stage is Continuous Testing, in which QA automated tests use Selenium and Robot Framework scripts, which are then run using Jenkins/Git in a virtualized environment. If the test fails, the process terminates here, and the issues are forwarded to the developers. Continue with the Continuous Deployment if the test succeeds.


Continuous Testing (CT) allows for cost-effective and speedy releases by finding faults early in the development cycle, leading to more efficient development and lower project expenses. Software delivery becomes much more agile with Continuous Testing, resulting in higher quality and rapid product releases. So, before implementing this testing technique in your company, make sure you have a sound plan in place.
