7. Test Automation:

Generative AI can be used to automate the process of writing automated test scripts, once it understands the system under test and its expected behavior, test scripts can be generated though generative models, it will reduce the manual efforts required for writing and maintain the automated tests.

Types of Generative AI Models:

Generative Adversarial Networks (GANs) :

This AI model generates new data closely resembling to the input data provided.

In QA, GANs can be used to generate wide array of test data using the pre existing test data. GANs consists of “generator” to create a new data and “discriminator” to evaluate and validate the generated data. Using these dual structure, GANs model is capable of producing highly realistic test scenarios.

Transformers :

As another model of Generative AI, it is excellent in understanding data context and sequencing within the data.
It analyses entire input data before generating the output so model is allowed to consider the broader context.
Ability to generate output based on broader context, this model can be used to harness the QA testing process.

Generative AI Use cases

Example generation based on description:

This is based on the AI model’s capability of understanding the description and generating relevant examples subsequently. This can be used to create a wide array of test cases based on given test case examples.

Example: 

Let’s consider an example using this model where a QA engineer provides a brief description like, “Test user registration flow.” The AI model understands the given requirement and produces test case examples, essentially reducing the manual effort.

Individual tests generation based on description:

Generative AI can generate complete tests based on the provided description. Unlike only providing the examples, AI can comprehend the requirement and develop full-fledged test along with the necessary setup for the test environment.

Example:

Let’s consider an example, for a given description like, “Develop a full test for a invoicing flow of an ecommerce platform”, the AI model would analyze the requirement, generate the necessary code, and design a test environment, all while minimizing human intervention.
