Tools are extremely important for performance testing, since testing without tools to automate the process is impractical.
Therefore, we have a specific domain that deals with the tools and methods used.
Tools are available on the market for virtually the entire performance testing life cycle. As for the methods, some approaches to performance testing (load, stress, spike, etc.), as well as techniques (scripting, capture \& replay) should be analyzed and chosen according to the test purpose and context.
