Issues, Challenges and Best Practices of Software Testing Activity Issues, Challenges and Best Practices of Software Testing Activity ZULKEFLI MANSOR Research Center for Software Technology and Management Faculty of Information Science and Technology Universiti Kebangsaan Malaysia 43000 Bangi, Selangor Darul Ehsan MALAYSIA [email protected] http://www.ftsm.ukm.my/kefflee ENEBELI E.NDUDI Faculty of Computer Science and Information Technology Universiti Selangor Jln Timur Tambahan, 45700 Bestari Jaya, Selangor Darul Ehsan MALAYSIA [email protected] Abstract: - Software testing activity is a huge challenge in software development project today due to end user needs. The end users need the project to be completed in short time with zero defect and high quality of product. Therefore, the testing activity should be started as earlier as possible because it will helps in fixing enormous errors in early stages of software development and reduces the rework of tracking bugs in the later stages. In addition, a clear understanding on the objective of testing and the planning on how, where, and what the system should be tested for is also challenges to the testing team. These issue makes software testing time consuming process coupled with various challenges erupting from inability of software testers to perform their task effectively. Hence, this paper investigated the issues, challenges and best practices of software testing activity. The document analysis was carried out in order to analyze the information. The findings reveals that 9 main issues and challenges in software testing activities. 9 best practices also discover from the survey. The findings will help software community especially testing team to aware the issues and challenges could be faced and how to perform testing activities in best way. Key-Words: - Quality, Effort, Failure, Product, Bugs, Defect, Error 1 Introduction constitutes a crucial part of software development Software products are fast growing and succeeding process. Inefficient or lack of testing has caused in easing end-user needs to complete various task much software project failure in the past, also have using computers in the recent years. The end-user led to some social problems and financial losses due often wants to get software products to be to its inability to meet stakeholder’s expectations. implemented as soon as possible. They need a Regardless of efforts made by software engineers to developed software product with new features to be contain the challenges of software testing, software created within short period of time. However users product have never been disassociated with bugs or do not want to deal with defected software product. defects. Prior research pointed the incompetence of In order to maximize profits and keep happy a software tester to be the root of challenges facing customers, software development industries utilize software quality assurance. However, challenges of various developments disciplined to create a product software testing did not just attached to incompetent that meets end-user requirements. Failure to meet tester but other factors such as poor documentation, user requirement has cost several software product poor planning, software domain and others. In order to exist even add extra problem to industries. to solve testing challenges, it is important to Studies have shown that software failure is traceable perform testing over and over and quest for to ineffective testing of the system under undercover future defect. This paper tends to development. Researchers have recommended address the issues and challenges facing software regular testing by competent individual to counter testing by reviewing prior challenges that were ineffective testing challenges. Software testing articulated by various researches. Solutions to the challenges as suggested by prior studies are to be 3.1 Inability of Testing to Detect Uncovers discussed and presented for awareness such as bug Defects detection and finally testing best practices. Some testing activity unable to detect uncover Although testing is cable detecting present bug defect due to few constraints such as lack of in software product but cannot predict or uncover experiences of testing team, no automated tool, lack future errors. This make testing time consuming of knowledge and others. Ahamed [4] mentioned practice as testers scrutinize the entire system often that unidentified bugs could causes future software to contain these challenges. Testing of software is a failure. The problem of performing a software widespread validation method within industry, but it testing is for defect detection which software can is still largely ad hoc, expensive, and uncertain only suggest the presence of flaws, not their effective. Therefore a solution to these challenges is absence. The essence of software testing is to to test a system completely. Nevertheless, software explore the whole system in search of bugs or for tester always faced with lack of time and resources, defect detection, and reliability estimation. which is capable of limiting their ability to Furthermore, [5] also supported the statement that effectively complete software testing efforts, thus testing can be used to show the presence of errors, ruling out exhaustive testing [1].

Agile environment?”. They start using Scrum as a framework for developing their software and while implementing, they experience trouble on how to deal with the Defects they find/cause along the way. Scrum is a framework that does not explicitly tell you how to handle Defects. The strait forward answer is to treat your Defects as Product Backlog Items that should be added to the Product Backlog. When the priority is set high enough by the Product Owner, they will be picked up by the Development Team in the next Sprint. The application of this is a little bit more difficult and hence should be explained in more detail. RON ERINGA 1. What is a defect?

  • Bug Detection, Debugging, and Isolation Middlebox for Software-Defined Network Controllers
    BuDDI: Bug Detection, Debugging, and Isolation Middlebox for Software-Defined Network Controllers Rohit Abhishek1, Shuai Zhao1, Sejun Song1, Baek-Young Choi1, Henry Zhu2, Deep Medhi1 1University of Missouri-Kansas City, 2Cisco Systems frabhishek, shuai.zhao, songsej, choiby, dmedhi)@umkc.edu, [email protected] Abstract—Despite tremendous software quality assurance ef- forts made by network vendors, chastising software bugs is a difficult problem especially, for the network systems in operation. Recent trends towards softwarization and opensourcing of net- work functions, protocols, controls, and applications tend to cause more software bug problems and pose many critical challenges to handle them. Although many traditional redundancy recovery mechanisms are adopted to the softwarized systems, software bugs cannot be resolved with them due to unexpected failure behavior. Furthermore, they are often bounded by common mode failure and common dependencies (CMFD). In this paper, we propose an online software bug detection, debugging, and iso- lation (BuDDI) middlebox architecture for software-defined net- work controllers. The BuDDI architecture consists of a shadow- controller based online debugging facility and a CMFD mitigation module in support of a seamless heterogeneous controller failover. Our proof-of-concept implementation of BuDDI is on the top of OpenVirtex by using Ryu and Pox controllers and verifies that the heterogeneous controller switchover does not cause any Fig. 1.

Most initial robots operated in teach-playback mode, and replaced ‗repetitive‘ and ‗back-breaking‘ tasks. Growth and usage of robots slowed significantly in late 1980‘s and early 1990‘s due to ―lack of intelligence‖ and ―ability to adapt‖ to changing environment – Robots were essentially blind, deaf and dumb!.Last 15 years or so, sophisticated sensors and programming allow robots to act much more intelligently, autonomously and react to changes in environments faster.

  • Identifying Software and Protocol Vulnerabilities in WPA2 Implementations Through Fuzzing
    POLITECNICO DI TORINO Master Degree in Computer Engineering Master Thesis Identifying Software and Protocol Vulnerabilities in WPA2 Implementations through Fuzzing Supervisors Prof. Antonio Lioy Dr. Jan Tobias M¨uehlberg Dr. Mathy Vanhoef Candidate Graziano Marallo Academic Year 2018-2019 Dedicated to my parents Summary Nowadays many activities of our daily lives are essentially based on the Internet. Information and services are available at every moment and they are just a click away. Wireless connections, in fact, have made these kinds of activities faster and easier. Nevertheless, security remains a problem to be addressed. If it is compro- mised, you can face severe consequences. When connecting to a protected Wi-Fi network a handshake is executed that provides both mutual authentication and ses- sion key negotiation. A recent discovery proves that this handshake is vulnerable to key reinstallation attacks. In response, vendors patched their implementations to prevent key reinstallations (KRACKs). However, these patches are non-trivial, and hard to get correct. Therefore it is essential that someone audits these patches to assure that key reinstallation attacks are indeed prevented. More precisely, the state machine behind the handshake can be fairly complex. On top of that, some implementations contain extra code to deal with Access Points that do not properly follow the 802.11 standard. This further complicates an implementation of the handshake. All combined, this makes it difficult to reason about the correctness of a patch. This means some patches may be flawed in practice. There are several possible techniques that can be used to accomplish this kind of analysis such as: formal verification, fuzzing, code audits, etc.
