Test strategies are structured plans that outline how testing will be conducted in a project. They help ensure that all aspects of a product, such as software or hardware, are thoroughly evaluated for quality and performance. By defining objectives, resources, and timelines, test strategies guide teams in identifying potential issues early in the development process. Different types of test strategies include unit testing, integration testing, and system testing. Each type focuses on specific components or interactions within a system. A well-defined test strategy not only improves product quality but also enhances team efficiency and communication throughout the testing phase.
