    A Framework for Evaluating Performance of Software Testing Tools

    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 02, FEBRUARY 2020 ISSN 2277-8616 A Framework For Evaluating Performance Of Software Testing Tools Pramod Mathew Jacob, Prasanna Mani Abstract: Software plays a pivotal role in this technology era. Due to its increased applicable domains, quality of the software being developed is to be monitored and controlled. Software organization follows many testing methodologies to perform quality management. Testing methodologies can be either manual or automated. Automated testing tools got massive acceptability among software professionals due to its enhanced features and functionalities than that of manual testing. There are hundreds of test automation tools available, among which some perform exceptionally well. Due to the availability of large set of tools, it is a herculean task for the project manager to choose the appropriate automation tool, which is suitable for their project domain. In this paper, we derive a software testing tool selection model which evaluates the performance aspects of a script-based testing tool. Experimental evaluation proves that, it can be used to compare and evaluate various performance characteristics of commercially accepted test automation tools based on user experience as well as system performance. Index Terms: Automated testing, Software testing, Test script, Testing Tool, Test bed, Verification and Validation. —————————— ◆ —————————— 1 INTRODUCTION S OFTWARE is advanced in recent days by enhancing its applicable domains. Software is embedded in almost all electronic gadgets and systems. In this scenario the quality of the software plays a significant role. The customer or end – user should be satisfied which is primarily depended on quality and capability of the software being developed.
  • Automated Testing of Firmware Installation and Update Scenarios for Peripheral Devices

    Automated Testing of Firmware Installation and Update Scenarios for Peripheral Devices

    DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Automated testing of firmware installation and update scenarios for peripheral devices DAG REUTERSKIÖLD KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Automated testing of firmware installation and update scenarios for peripheral devices DAG REUTERSKIÖLD Master in Computer Science Date: August 12, 2019 Supervisor: Hamid Faragardi Examiner: Elena Troubitsyna School of Electrical Engineering and Computer Science Host company: Tobii AB Swedish title: Automatisering av enhetsinstallation, uppdatering och testning med hjälp av virtuella maskiner iii Abstract This research presents an approach to transition from manual to automated testing of hardware specific firmware. The manual approach for firmware test- ing can be repetitive and time consuming. A significant proportion of the time is spent on cleaning and re-installing operating systems so that old firmware does not interfere with the newer firmware that is being tested. The approach in this research utilizes virtual machines and presents an automation framework. One component of the automation framework is an application to imitate con- nected peripheral devices to bypass hardware dependencies of firmware in- stallers. The framework also consists of automation and pipeline scripts with the objective to execute firmware installers and detect errors and abnormalities in the installation and updating processes. The framework can run on locally hosted virtual machines, but is most applicable using cloud hosted virtual ma- chines, where it is part of a continuous integration that builds, downloads, installs, updates and tests new firmware versions, in a completely automated manner. The framework is evaluated by measuring and comparing execution times with manually conducted installation and updating tests, and the result shows that the framework complete tests much faster than the manual approach.

  • Difference Between Perl and Python Key Difference

    Difference Between Perl and Python Key Difference

    Difference Between Perl and Python www.differencebetween.com Key Difference - Perl vs Python A computer program provides instructions for a computer to perform tasks. A set of instructions is known as a computer program. A computer program is developed using a programming language. High-level languages are understandable by programmers but not understandable by the computer. Therefore, those programs are converted to machine-understandable format. Perl and Python are two high-level programming languages. Perl has features such as built-in regular expressions, file scanning and report generation. Python provides support for common programming methodologies such as data structures, algorithms etc. The key difference between Perl and Python is that Perl emphasizes support for common application-oriented tasks while Python emphasizes support for common programming methodologies. What is Perl? Perl is general purpose high-level programing language. It was designed by Larry Wall. Perl stands for Practical Extraction and Reporting Language. It is open source and is useful for text manipulation. Perl runs on various platforms such as Windows, Mac, Linux etc. It is a multi-paradigm language that supports mainly procedural programming and object-oriented programming. Procedure Programming helps to divide the program into functions. Object Oriented programming helps to model a software or a program using objects. Perl is an interpreted language. Therefore, each line is read one after the other by the interpreter. High-level language programs are understandable by the programmer, but they are not understandable by the machine. Therefore, the instructions should be converted into the machine-understandable format. Programming languages such as C and C++ converts the source code to machine language using a compiler.

John Ousterhout of the University of California, Berkeley, designed it. It is a combination of a scripting language and its own interpreter that gets embedded to the application, we develop with it. Tcl was developed initially for Unix. It was then ported to Windows, DOS, OS/2, and Mac OSX. Tcl is much similar to other unix shell languages like Bourne Shell (Sh), the C Shell (csh), the Korn Shell (sh), and Perl. It aims at providing ability for programs to interact with other programs and also for acting as an embeddable interpreter. Even though, the original aim was to enable programs to interact, you can find full-fledged applications written in Tcl/Tk. Features of Tcl The features of Tcl are as follows − ∑ Reduced development time. ∑ Powerful and simple user interface kit with integration of TK. ∑ Write once, run anywhere. It runs on Windows, Mac OS X, and almost on every Unix platform. ∑ Quite easy to get started for experienced programmers; since, the language is so simple that they can learn Tcl in a few hours or days. ∑ You can easily extend existing applications with Tcl.
  • PHP: Constructs and Variables Introduction This Document Describes: 1

    PHP: Constructs and Variables Introduction This Document Describes: 1

    PHP: Constructs and Variables Introduction This document describes: 1. the syntax and types of variables, 2. PHP control structures (i.e., conditionals and loops), 3. mixed-mode processing, 4. how to use one script from within another, 5. how to define and use functions, 6. global variables in PHP, 7. special cases for variable types, 8. variable variables, 9. global variables unique to PHP, 10. constants in PHP, 11. arrays (indexed and associative), Brief overview of variables The syntax for PHP variables is similar to C and most other programming languages. There are three primary differences: 1. Variable names must be preceded by a dollar sign ($). 2. Variables do not need to be declared before being used. 3. Variables are dynamically typed, so you do not need to specify the type (e.g., int, float, etc.). Here are the fundamental variable types, which will be covered in more detail later in this document: • Numeric 31 o integer. Integers (±2 ); values outside this range are converted to floating-point. o float. Floating-point numbers. o boolean. true or false; PHP internally resolves these to 1 (one) and 0 (zero) respectively. Also as in C, 0 (zero) is false and anything else is true. • string. String of characters. • array. An array of values, possibly other arrays. Arrays can be indexed or associative (i.e., a hash map). • object. Similar to a class in C++ or Java. (NOTE: Object-oriented PHP programming will not be covered in this course.) • resource. A handle to something that is not PHP data (e.g., image data, database query result).
