Debuggers, Source Control Keys to Quality

Don't touch that runtime debugger or source code/version control system! Those are the most important weapons in a software development team's arsenal, according to a survey conducted by BZ Research, like SD Times a subsidiary of BZ Media LLC (www.bzmedia.com). The study was submitted to a random sampling of 4,172 qualified SD Times readers in February.

When asked the types of testing/debugging tools currently being used, 66.1 percent of the respondents indicated that runtime debuggers were in use, and 64 percent used source-code control systems or version control systems.

Other collaborative development or debugging systems fared less well on the survey. Team-based defect tracking systems are in use by 35.4 percent of teams, team-based configuration management systems by 23.6 percent, and end-user defect registration systems are used by 23.1 percent of SD Times' readers, which mainly consist of software development managers at large enterprises.

Beyond debuggers, the most widely used testing tool, at 36.5 percent, was a performance tester or profiler, followed by unit testers (24.1 percent), load testers (22.6 percent), black-box testers (21.3 percent), regression testers (18.4 percent), security test solutions (16.8 percent) and white-box testers (16.3 percent). Automatic test-script generators, data monitors, simulators, cross-platform debuggers and in-circuit emulators were used by fewer than one in six SD Times readers.

PLATFORM TESTINGThe survey also asked SD Times readers what types of code they and their teams are currently debugging. The highest response, 59.3 percent, was for database applications, not surprising given the widespread adoption of database-centric, n-tiered application development.

Web technologies were high on the list, with 52 percent of development teams debugging HTML code and 42.8 percent debugging XML, followed by dynamic HTML based on technologies such as Active Server Pages, Microsoft's ASP.NET or Sun's JavaServer Pages. Web services, despite being such a new technology, were being debugged by 18.6 percent of readers.
