EarthCube was initiated by the National Science Foundation (NSF) to transform geoscience research by developing cyberinfrastructure to improve access, sharing, visualization, and analysis of all forms of geosciences data and related resources. EarthCube software test-bed project was awarded to create a technology and software validation framework for integration, testing and demonstrations. This paper...
Clients today want more for less and the IBM test mantra of Test Less Test Right helps address this ask by placing Combinatorial Test Design (CTD) at the heart of the solution. This document presents two case studies of CTD implementation in client engagements and focuses on the approach, process and challenges addressed to scale up the implementation and make CTD a mainstream activity. The IBM Focus...
There exist several coverage-based approaches to reduce time and resource costs of test execution. While these methods are well-investigated and evaluated for smaller to medium-size projects, we faced several challenges in applying them in the context of a very large industrial software project, namely SAP HANA. These issues include: varying effectiveness of algorithms for test case selection/prioritization,...
Test Driven Development as well as the documentation of tests and their architecture are today an important pillar of software quality assurance. The change of requirements during the implementation phase entails a need to change tests as well as the test documentation of the software. Since unit tests are specified in the implementation language, an interdisciplinary readable documentation must be...
With a growing amount of transferred data in an interconnected world, the insurance of a secure communication between two peers becomes a critical task in the software industry. A leak of critical data can cause tremendous costs in a financial, social but also political manner. For this sake, cryptographic protocols are implemented and regulate the data transfer, thus ensuring the safety of transferred...
In this paper we assess and evaluate the quality of t-way combinatorial test-suites using three different test-suite quality assessment methods. As t-way combinatorial test-suites reduce the input space of a program under test, we investigate how an increasing t affects the quality of the test-suite. There are some limitations of existing test-suite quality assessment methods e.g. the number of mutants...
The fifth version of HTML standard, which is widely accepted in the diverse landscape of browser vendors and their continuously upgrading releases, requires web browsers to support playback of multimedia natively, instead of by third-party plugins. Works on testing browsers' implementations of the HTML5 support, however, are not efficient enough till now. Regarding a browser's processing on HTML5...
Data mining algorithms are used to analyze and discover useful information from data. This paper presents an experiment that applies Combinatorial Testing (CT) to five data mining algorithms implemented in an open-source data mining software called WEKA. For each algorithm, we first run the algorithm with 51 datasets to study the impact different datasets have on the test coverage. We select one dataset...
In this paper we suggest the quantification method which can verify the efficiency of the current test design. The existing coverage measuring method cannot verify if SW safely works, and has a difficulty with a different level of understanding between a test case author and an administrator. It also provides the base to measure the outcome of the executed test. Using the suggested coverage measuring...
New web development technologies enhance functionality of web applications but also introduce challenges in testing the software. As mutation analysis has been shown to be effective at designing tests for traditional software, we previously proposed web mutation testing. However, applying mutation analysis can be computationally expensive due to an extensive number of test requirements. This paper...
In a growing number of domains, the provisioning of end-to-end services to the users depends on the proper interoperation of multiple products, forming a new distributed system. To ensure interoperability and the integrity of this new distributed system, it is important to conduct integration tests that verify not only the interactions with the environment but also the interactions between the system...
Previous work has demonstrated that property-based testing (PBT) is a flexible random testing technique that facilitates the generation of complex form data. For example, it has been shown that PBT can be applied to web-service applications that require various inputs for web-forms. We want to exploit this data generation feature of PBT and combine it with an external test-case generator that can...
To test a Software Product Line (SPL), the test artifacts and the techniques must be extended to support variability. In general, when new SPL products are developed, more tests are generated to cover new or modified features. A dominant source of extra effort for such tests is the concretization of newly generated tests. Thus, minimizing the amount of new nonconcretized tests required to perform...
The notion of composition in the context of combinatorial test design naturally arises in situations where the output of one module is used as an input to another module. Composability of tests plans has several important benefits as it facilitates both test and model reuse in such sequential scenarios. In this paper we describe a method for an automatic construction of composable tests plans, one...
A track circuit is a critical component of a modern railway system. The circuit is used to detect the absence of a train on rail tracks and produce corresponding control signals. A railway track has many block sections, each of which has a separate track circuit device. A track circuit receiver analyzes signals sent from a track circuit sender and produces a signal to control a relay. When the train...
Combinatorial Testing is a test design methodology that aims to detect the interaction failures existing in the software under test. The combinatorial input space model comprises of the parameters and the values it can take. Building this input space model is a domain knowledge and experience intensive task. The objective of the paper is to assist test designer in building this test model. A rule...
The base-choice criterion was proposed as a suitable technique for testing software based on its nominal choice of input parameters. Test cases are created based on this strategy by varying the values of one input parameter at a time while keeping the values of the other parameters fixed on the base choice. However, this strategy might not be as effective when used on industrial control software for...
In this paper, we review and prove certain properties regarding t-way coverage when covering arrays are merged together to form larger arrays. Moreover, we build upon these theoretical observations to formulate a procedure on how, from the input space model of a composed SUT and t-way test suites for its components, to create a larger and unified t-way test suite. The proposed modelling methodologies...
A good automated testing tool could reduce as much as possible the manual work done by testers. In order to improve the traditional record-replay approach and reduce the effort that the testers spending on writing test scripts, we propose an approach that generates the Android application test scripts based on accessibility service without connecting to a computer. This approach simulates user input...
Following the Service-Oriented Architecture, Cloud services are exposed as Web APIs (Application Program Interface), which serve as the contracts between the service providers and service consumers. With increasing massive and broad applications of Cloud-based development, a large number of diversified APIs are emerging. Due to their wide impacts, any flaw in the cloud APIs may lead to serious consequences...
