The AGILE Manifesto, considered by many to be the Bible of all things Agile, lays out the foundation for Agile. It is a document that OUTLINES the central values and principles of Agile Software development. The four core Agile values help the team to improve their work processes. They help to improve upon the old traditional process which was not efficient and was so rigid that it could not easily handle changes.

The Agile Manifesto impacts Agile testers in many ways, which are outlined below:

• Individuals and interactions over processes and tools: Testers have to work CLOSELY with customers, developers, and product owners so that they are aware of the scope and tasks that they are developing
• Working software over comprehensive documentation: Testers do not have DETAILED documentation/ requirements handy using which they can test against. They have to carefully pen down and refine the acceptance criteria and carry out testing with the help of Scrum teams.
• Responding to change over following a plan: Agile IMPLEMENTS an incremental approach and responds to changes in the scope at any point in time. Testers have to prioritize and reprioritize their tests, while at all times focussing on achieving the required goals of the customer.
• Collaborating with customers over contract negotiation: Agile testers have to focus on stability, security, and new features that are in line with customers’ evolving needs.
