Performance thresholds help solidify the goals for testing and help assess the quality of application code or of the test scripts. Thresholds can be implemented as [[Requirements]] at the start of a testing phase or as criteria for every load test run that is executed. However, requirements are not necessarily thresholds-- they can be observations about the work that are not even quantifiable. [[Set multiple thresholds|Setting multiple thresholds]] is a feature that is available on many load testing tools. Thresholds are sometimes called [[Service Level Objective (SLO)]]s, failure criteria, or success criteria. A set of thresholds encompassing multiple metrics is referred to as a [[Service Level Agreement (SLA)]]. [[Service Level Indicator (SLI)]] s are similar to [SLOs]([[Service Level Objective (SLO)]]), but they are the current value for a specific test, so they operate on a more micro level. ## Related - [[Load Testing]] - [[Performance Testing]] - [[Planning for load testing]] - [[Basics of Thresholds and SLOs]]
