Best Load Testing Software

    Load testing software tests software products, websites, and servers by adding load pressure and measuring the response. Development teams use this software as a part of a larger software testing regimen to verify developed products, websites, and servers can handle the various stresses of day-to-day use, as well as high-impact uses (e.g., holiday shopping, enterprise application use, etc.). Load testing tools work well with load balancing software, often being integrated to stress points of impact during testing and then manage those stresses as they occur.

    To qualify for inclusion in the Load Testing category, a product must:

    Stress test software products, websites, and servers
    Test extreme cases for software, website, and server use
    Generate reports on strengths and weaknesses revealed during testing
