Load Testing tools evaluation - SOAP UI vs Jmeter. Each thread represents one user using the application. Step 1: Thread Group - make loop count = forever. Random Controller was not an option as it actually does not guarantee that the next thread will run another sampler. Check 'Run Thread Groups consecutively' in the Test Plan to first run the thread group to load the data and then the thread group for the test suite. 매번 설치해서 테스트를 해보겠다 해보겠다 했는데, 자꾸 미뤄서, 이번 테스트 할때를 기회삼아서, jMeter에 대해서 설치부터 전체적인 테스트 플랜 짜는 것과 JMeter 구동하는 것까지 전체적으로 정리를 해보도록.
