Software Risk Management (SRM) combines a set of tools, processes, and methods for managing risks in the software development lifecycle. In SRM, we want to make informed decisions about what can go wrong at various levels within a company (e.g., business, project, and software related).
As part of one of my consulting efforts, I worked with a mid-sized company that was looking to move toward a more agile manner of developing software. As with any shift in work style, there is some bewilderment and, for some, considerable anxiety. People are being challenged to leave their comfort zones and embrace a continuously changing, dynamic working environment. And, dare I say it, testing may be the most ‘disturbed’ of the software roles in agile development.
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.
Entering the world of testers, one question started to formulate in my mind: “what is the reason that bugs happen?”.
JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
