Know What Works with Semantic Design's Test Coverage Analysis Tool for C#/.Net

Share Article

Semantic Designs of Austin Texas announces general availability of the Test Coverage Tool for C# 4.0. The Test Coverage Tool parses C# source code, analyzes it, and generates new code can be compiled and run to determine exactly what lines of code have been executed as part of one or more tests. An easy-to-understand graphic display of code coverage along with overall metrics is the result of the tool. Semantic Designs tools are in use with a variety of critical enterprise and embedded systems applications, with C# just one of a variety of languages supported.

The Truth Is In The Details

Test coverage analysis is critical to effective modern software quality assessment. This tool lets you know where you really stand.

Today’s Agile development processes put an emphasis on building and regularly executing tests, but how do you know what has really been tested? Oftentimes tests exercise a small percentage of the overall system code, regardless of how many tests exist or how often they are run. It is highly important to know exactly which lines of code have been tested and the overall percentage of code “covered” is a key metric for Software Quality Assurance.

"Test coverage analysis is critical to effective modern software quality assessment. This tool lets you know where you really stand," says Dr. Ira Baxter, Founder and CEO of Semantic Designs.

The C# (C-Sharp) Test Coverage tool enables the collection and display of code coverage data on C# software source code bases of any size. It is a member of Semantic Design's family of Test Coverage Tools and works in conjunction with Semantic Design’s other tools and support for other languages. Semantic Designs specializes in dealing with very large codes bases in multiple languages. Multi-million line systems are no problem for this line of tools.

Semantic Design's test coverage tools operate by inserting language-specific probes for each basic block in the source files of interest before compilation/execution. At execution time, the probes record which blocks were executed ("coverage data"). On completion of execution, the coverage data is typically written to a test coverage vector file. Finally, the test coverage data is displayed on top of browsable source text for the system under test, enabling a test engineer to see what code has (or has not) been executed, and to see overall statistics on coverage data. Additional tests can then be added to extend code coverage to meet Software Quality Assurance goals.

Features:

  • Works with small code bases or large systems of thousands of files
  • Very low probe overhead (one or two machine instructions per executed probe)
  • Can accumulate coverage data from multiple execution runs
  • Browsable source files overlaid with collected coverage information
  • Produces coverage report by application, subsystem and file
  • Test Coverage delta computation and display, to enable test case minimization
  • Can operate with custom/embedded application execution environments
  • Consistent style and operation across different languages
  • Probe installer and display tool operate on Windows 2000/XP/Vista/7
  • Application under test can execute in arbitrary native environment including embedded
  • Test coverage data from multiple subsystems can be combined into single comprehensive display and summary reports
  • Test coverage data from multiple languages can be combined into single comprehensive display and summary reports
