Agile Testing Principles: Explained


In this fast-growing world, the needs and requirements of the customers are changing continuously. So the customers want to use the products that can meet their expectations.

The same concept applies in the Software Development industry. Now the software is required to be agile enough to continuously reshape them according to the user’s need.

To cope up with these fast changes without comprising with the quality of the product testing process needs to evolve to be quick and more efficient.

To overcome these software testing challenges agile testing principles should be adopted. Agile automation testing is a smarter way of testing software that involves complex development processes.

What is Agile Testing?

Agile testing is a way of testing the software that follows the agile software development process. In this process, the development cycle keeps on going iteratively to update the software as per the new requirements evolved due to stakeholders interaction.

Here the development is driven by the customer’s needs. Agile testing allows enterprises to quickly release or deliver the new updates which are most likely to work as the development is the result of the customers and the development teams requirements.

Agile testing is done in parallel with the development process. Any changes in the software require the testing team to undertake to test so that the changes can be allowed to affect the existing product.

Features of Agile Development Process?

agile testing principles

1. In the agile development process, customer satisfaction is the development team’s main focus. It uses the principle of early delivery to start getting feedback from the customers as early as possible.

This feedback later decides the direction of further development and this process continues to let the customer know about the progress of the software.

2. Even if the development process has gone too far, but if the requirements in the earlier stage changes then also the changes should be implemented. To ensure this the changes process should be simple which any special documentation requirements.

It expresses the responsive behaviour of the enterprises. It also provides them with the opportunity to have a customer advantage.

3. The product with the changes should be released frequently. With the addition of each feature, the product should go live, ensuring all the features are working as they are supposed to do.

4. Business peoples and the development teams are required to work in collaboration with each other to continuously keep a check on the new customer requirements. The frequent communication between these two bits of help in building software satisfying both customer and business needs.

What are the principles of Agile Testing?

There are various agile testing principles and practices that are followed some of them are given below:

1. Testing is done continuously throughout the software development life cycle to ensure the progress of the development in the right direction and prevent a large number of bugs in the software.

2. Agile testing also provides continuous feedback which helps in ensuring quality at every step of development and is on the right path for good user experience and business needs.

3. Testing process is made much faster by making the business peoples to also work with the development team as it reduces the validation time of any new feature.

This practice was missing in the traditional way of testing.

4. The time required for feedback response is decreased by business analyst involvement in every iteration of testing.

5. The bugs detected during testing are fixed in the same iteration hence help in keeping the code simple and clean. It is considered easy to fix small bugs frequently than fixing a lot of bugs in one go after a long interval of time.

6. The testing team uses reusable checklist which allows them to focus more on testing rather on incidental details.

7. In agile testing, the testing is done during the implementation of software unlike in traditional testing, the testing is done after the implementation of the software.

agile testing principles and advantages

Advantages of Agile Testing?

1. Agile testing reduces the time and money of development as the defects in the software are fixed as soon as they are detected.

2. It also reduces the need for documentation, hence increases the productivity of testing teams.

3. The agile testing process is highly flexible and adaptive to changes in the software during the development stage. So there will not be much trouble in testing due to software update.

4. Agile testing also provides a way for receiving continuous feedback from the end-user, so the more amount of feedback received, the easier it is to solve issues and understand the user’s requirements.

5. The issues are better determined because of the daily meeting of the team. Agile testing requires the whole team to come together. So that everyone stays well informed about what’s going in the software.

Methods of Agile Testing

1. Behaviour-Driven Development

It improves communication among the project stakeholders. It allows every member to understand each feature properly before the development starts.

It ires the communication among the development team, testers and the business peoples. This communication is based on examples of different scenarios. These scenarios are written in a special format, holding the information about how a feature should react in different situations and different inputs parameters.

These are called executable specifications as they contain both specifications and the kind of input to the automated tests.

2. Acceptance Test-Driven Development

This type of development strategy requires team members with three kinds of perspectives:

1. Customer

The customer is focused on what is the problem to be solved with the aid of software 

2. Developers

The development team focuses on how the problem will be solved.

3. Testing

The testing focuses on what can go wrong in the software during development and should be tested.

All three of them help in formulating the acceptance test plan. The acceptance test is done keeping the user’s point of view on focus and determines how the system should work.

It verifies that the system is working the way it is supposed to. Acceptance test can also be done automatically.

3. Exploratory testing

Exploratory testing is the one in which the test designing and test implementation undergo simultaneously.

In this, the tester learns the application by exploring it and then design the test to check the functionality. This test is then executed to produce some result which is compared with the expected result.

So this is how agile testing is dealing with software testing challenges in a fast-changing changing world.
