Applied Technology Lab

Established: 2007

Partnership between WVU and NASA’s Independent Verification and Validation (IV&V) facility in Fairmont, WV

Goal: Researching software engineering technologies that improve and enhance the way NASA produces safe and reliable system software

Director: Dr. Tim Menzies, Ph.D.

IV&V Rep.: Pier Luigi Long

Problem

IV&V and D&T facilities expressed a need for automated assistance with various STOL script development, testing and analysis activities

The variety of STOL directives, embedded mission-specific commands, and the distributed real-time telemetry environment in which they operate provide a challenge in the handling of STOL scripts

Currently users have no automated methods to assist in the development, testing and analysis activities or metrics to assist in these activities

IV&V ATL


6

Benefits

Improve the quality and timeliness of test verification of STOL-based systems

Ongoing standards activities could help unify, advance, and further broaden the use of a common STOL-like language in future NASA projects

A platform-independent integrated toolset based on the Eclipse IDE framework designed to assist NASA IV&V practitioners in the analysis of STOL scripts

IV&V ATL


7

Features

STOL editor – allows users to browse through a group of STOL files with language-sensitive styling and drill-down capabilities

Log viewer – allows users to navigate through log files created during execution of the STOL script along with the associated STOL source files in an integrated and synchronized fashion

Platform independent, built upon the Eclipse IDE as plugins- all features of the Eclipse Workbench are included

Takes in STOL scripts and certain (stamped) associated log files

Outputs visual displays and annotations, exportable as XMI

Works on ASIST STOL Scripts (extend to EPOCH, CSTOL)

IV&V ATL


8

Relevance

Many variants of STOL still in use at NASA and by its prime contractors

Ongoing standards activities could help unify, advance, and further broaden the use of a common STOL-like language in future NASA projects

Trend toward model-based architectures and model-driven methodologies

Trend toward Eclipse plugin tools

IV&V ATL


9

Maturity

Tested and applied to GSFC project scripts and logs

JHU/APL – EPOCH STOL scripts and simulated streams

Various IV&V projects

IV&V ATL


10

Requirements

Any platform supporting Eclipse, Java and Antlr

Requires STOL scripts and certain (stamped) associated log files as input

IV&V ATL

Importing FilesIV&V ATL


18

General UseIV&V ATL


The gray border at the left margin has icons that indicate if a line is found in a corresponding log file

Icons will also appear if you have created bookmarks or recorded notes in the Tasks view

You can view details for icons by moving the mouse cursor over them

Code folding is a supported feature

19

Go to Line in Log FileIV&V ATL


Point your cursor on a line of the procedure file and right-click to access the context menu actions

Select ‘Go to Line in Log File’

20

Go to Line in Log FileIV&V ATL


The corresponding line in any associated log files will be located

The log file will be opened if there is a match

21

Open FileIV&V ATL


Highlight an element of the procedure file loaded in the STOL editor and right-click

Select ‘Open File’

22

Open FileIV&V ATL


This will attempt to find other procedure and log files that have a similar name and open them

23

Find in ModelIV&V ATL


Place a cursor within the text of an element of the procedure file loaded in the STOL editor and right-click

Select ‘Find in Model’

24

Find in ModelIV&V ATL


This will attempt to find the selected element’s occurences in the model

25

Log ViewerIV&V ATL


An additional editor provided is log-based, and allows the user to see the code executed in line with the output from it

26

Model Outline ViewIV&V ATL


Displays the outline of a structured file that is currently open in the editor area and lists structural elements

To add the Outline view to the current perspective, select Window > Show View > Other… > General > Outline
