Development of Engineering Test Satellite, No. 1

Kazuya Yoshida Laboratory Test Beds Ten Years Ago , Now in Orbit Engineering Test Satellite VII

The Engineering Test Satellite VII (ETS-VII), an unmanned spacecraft equipped with a 2-m long, six-degree-of-freedom manipulator arm, was developed and launched by the National Space Development Agency of Japan (NASDA). ETS-VII has successfully carried out a variety of on-board experiments with its manipulator arm, and these key technologies are essential for an orbital free-flying robot. These...

1 Contract Driven Development = Test Driven Development - Writing Test - Cases

Although unit tests are recognized as an important tool in software development, programmers prefer to write code, rather than unit tests. Despite the emergence of tools like JUnit which automate part of the process, unit testing remains a time-consuming, resource-intensive, and not particularly appealing activity. This paper introduces a new method, called ContractDriven Development, that take...

Investigating the Potential of Test-Driven Development for Spreadsheet Engineering

It is widely documented that the absence of a structured approach to spreadsheet engineering is a key factor in the high level of spreadsheet errors. In this paper we propose and investigate the application of Test-Driven Development to the creation of spreadsheets. Test-Driven Development is an emerging development technique in software engineering that has been shown to result in better quali...
