effectively.</p><p> </p><p>From automatic recording that allows you to gain in productivity and realism in writing your scripts, through correlation that makes your test realistic and reusable across environments, the authors put you on the right track to realize your scalability testing campaigns.</p><p> </p><p>They then explore the different protocols offered by the tool through examples drawn from their professional experiences.</p><p> </p><p>Finally, they show how to integrate the tool into the DevOps approach, create professional reports and exploit the richness of its eco-system to integrate new protocols, enrich its monitoring or leverage its power through the use of the Cloud.</p></div><div class="about-book__meta"><ul class="meta-list"><li class="meta-list__item"><h3
