  • Web Performance Testing: Methodologies, Tools and Challenges
    International Journal of Scientific Engineering and Research (IJSER) www.ijser.in ISSN (Online): 2347‐3878 Volume 2 Issue 1, January 2014 Web Performance Testing: Methodologies, Tools and Challenges Vinayak Hegde1, Pallavi M S2 1Assistant .Professor, Dept. of Computer Science, Amrita Vishwa Vidyapeetham, Mysore Campus, India 2Lecturer, Department of Computer Science, Amrita Vishwa Vidyapeetham, Mysore Campus, India Abstract: The Internet is gently becoming the essential requirement for the business world, with web applications as the brains. This means that software faults in web applications have potentially disastrous consequences. Most work on web applications has been on making them more powerful, but relatively little has been done to ensure their quality. Important quality attributes for web applications include reliability, availability, interoperability and security. Web Performance testing is a type of testing intended to determine the responsiveness, reliability, throughput, interoperability and scalability of a system and /or application under a given workload. It could also be defined as a process of determining the speed or effectiveness of a computer, network, software application or device. Testing can be conducted on software applications, system resources, targeted application components, databases and a whole lot more. It normally involves an automated test suite as this allows for easy, repeatable simultaneous a variety of normal peak and exceptional load conditions. Such forms of testing help verify whether a system or application meets the specifications claimed by its vendor. This paper emphasis on methodology of performance testing and explains about various diagnostic tools to implement testing to overcome from single point of failure. This paper also explains about challenges of web performance testing and helps for one who takes up further research activity.

  • Client Software for Visualizing Test Automation Result
    Santeri Vaara Client Software for Visualizing Test Automation Result Metropolia University of Applied Sciences Bachelor of Engineering Information and Communications Technology Thesis 7 September 2018 Abstract Author Santeri Vaara Title Client Software for Visualizing Test Automation Result 47 pages Number of Pages 7 September 2018 Date Degree Bachelor of Engineering Degree Programme Information and Communication Technology Professional Major Smart Systems Instructors Juhana Sillanpää, squad group leader Hannu Markkanen, researcher teacher This bachelor’s thesis documents the development of client software as a part of a new test analysis tool. The client software includes communication with the server for fetching data and a graphical user interface for visualizing it. This project was conducted for a Finnish telecommunications company operating globally. As a starting point, software builds are tested daily with regression testing for ensuring that software works the same way as it did before changes. The tests are made with Robot Framework and they are executed in a Jenkins server. Jenkins server is used for continuous integration, which enables test automation. After executing tests, the test results are seen in a Jenkins build’s web-page with help of Robot Framework plugin. There are multiple Jen- kins builds executing thousands of tests daily. The tester's job is to analyze the failed tests and to ensure that test automation works. In addition to Jenkins web-page, the test results are stored into a data storage server. Storage server contains over a year of unused test result data. The purpose of this thesis was to develop a client software for visualizing the test result data from storage server.

  • A Brief Survey on Web Application Performance Testing Tools Literature Review
    International Journal of Latest Trends in Engineering and Technology (IJLTET) A Brief Survey on Web Application Performance Testing Tools Literature Review Isha Arora M.Tech Scholar, Department of Computer Science and Engineering , PIET, PANIPAT, INDIA Vikram Bali Department of Computer Science and Engineering, PIET, PANIPAT, INDIA Abstract - Web Testing is the complete testing of a web based system before it goes live on the internet. Due to increase in number of websites, the demand is for accurate, faster, continuous & attractive access to web content. So, before publishing it online, Testing process is required which includes basic functionalities of the site, User Interface compatibility, its accessibility, effect of traffic on server etc. This leads to the requirement of one handy and intelligent tool or application which provides these facilities of testing in an easy & automated way such that time & cost are minimized and testing is no more a headache. This paper presents an extensive Literature Survey of performance Automation Testing tools. This paper is first of two, the second is going on to consider the framework of Performance Automation tool that will carry its own new set of features which are desired by professionals and currently unavailable. Keywords: Software testing, Automation testing, Performance testing, Testing tools, Non functional testing I. INTRODUCTION Software Testing is the process used to help identify the correctness, completeness, security, and quality of developed computer software. Testing is a process of technical investigation, performed on behalf of stakeholders, that is intended to reveal quality related information about the product with respect to the actual functioning of the product, it includes the process of executing a program or application with the intent of finding errors.

    Thesis no: MSSE-2016-16 Comparative Study of Performance Testing Tools: Apache JMeter and HP LoadRunner Rizwan Bahrawar Khan Faculty of Computing Blekinge Institute of Technology SE-371 79 Karlskrona Sweden This thesis is submitted to the Faculty of Computing at Blekinge Institute of Technology in partial fulfillment of the requirements for the degree of Master of Science in Software Engineering. The thesis is equivalent to 20 weeks of full time studies. Contact Information: Author: Rizwan Bahrawar Khan [email protected] University advisor: Dr. Mikeal Svahnberg School of Computing Faculty of Computing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE-371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 i i ABSTRACT Software Testing plays a key role in Software Development. There are two approaches to software testing i.e. Manual Testing and Automated Testing which are used to detect the faults. There are numbers of automated software testing tools with different purposes but it is always a problem to select a software testing tool according to the needs. In this research, the author compares two software testing tools i.e. Apache JMeter and HP LoadRunner to determine their usability and efficiency. To compare the tools, different parameters were selected which guide the tool evaluation process. To complete the objective of the research, a scenario-based survey is conducted and two different web applications were tested. From this research, it is found that Apache JMeter got an edge over HP Loadrunner in different aspects which include installation, interface and learning. Keywords: Software Testing, Automated Software Testing, Performance Testing, Web Applications ACKNOWLEDGMENT I am specially thankful to Almighty Allah who helped me to complete this thesis.

Performance testing helps to understand the reliability, scalability, responsiveness, and throughput of software under a given workload owing to its popularity. Web services are increasingly used in web applications and testing them is comparatively difficult with regards to traditional applications in terms of unpredictable load, response time etc. This review paper presents a comparative study of web service testing tools by measuring response time and throughput. Moreover, after thorough examination changes are recommended for web services and testing tools. Keywords- Web services, LDAP, HTTP, generic TCP connections, JMS and native OS processes, GUI I. INTRODUCTION literatures and studies conducted around this area and analyses them. Section 3 describes the experimental study Performance Testing is done in order to determine the undertaken in order to achieve the objectives of this throughput as well as the response time on any software or research. Section 4 finally concludes the section with application. This also helps in calculating the time required formulating insights. to perform a task or run an application in the whole system. Additionally, performance testing also helps in meeting the II. RELATED WORK non-functional requirements that are listed in SRS (Software Requirement Specification) document.
