Continuous Integration explained with jenkins deployment

Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.

Using ChatGPT for Test Automation

ChatGPT broke all Internet records by going viral in the first week of its launch. A million users in 5 days are unprecedented. A conversational AI that can answer natural language-based questions and create poems, write movie scripts, write social media posts, write descriptive essays, and do tons of amazing things. Our first thought when we got access to the platform was how to use this amazing platform to make the lives of web and mobile app testers easier. And most importantly, how we can use ChatGPT for automated testing.

A Step-By-Step Guide To Cypress API Testing

API (Application Programming Interface) is a set of definitions and protocols for building and integrating applications. It’s occasionally referred to as a contract between an information provider and an information user establishing the content required from the consumer and the content needed by the producer.

Options for Manual Test Case Development & Management

The purpose of developing test cases is to ensure the application functions as expected for the customer. Test cases provide basic application documentation for every function, feature, and integrated connection. Test case development often detects defects in the design or missing requirements early in the development process. Additionally, well-written test cases provide internal documentation for all application processing. Test case development is an important part of determining software quality and keeping defects away from customers.
