Testwell Tools Overview

Testwell CTC++, Test Coverage Analyzer for C/C++
CTC++ is a powerful and easy-to-use code coverage and execution profiling tool. CTC++ provides the following code coverage measures:

• function coverage (functions called)
• statement coverage (percent of statements executed)
• decision coverage (known also as branch coverage, decisions true/false, case branches, catch branches, and program control flow branches executed in general)
• multicondition coverage (have all the possible ways to evaluate the conditional expression been executed)
• condition coverage (true/false counts of elementary conditions in a conditional expression)
• MC/DC coverage (do all the elementary conditions in a conditional expression meet the MC/DC coverage criteria)

• how many times each program location has been executed
• timing instrumentation (total, average, longest execution time of functions, user-definable time-taking function)
• function call tracing

CTC++ can be used from command line scripts and via makefiles. There are also IDE integrations to some development environments, notably to Microsoft Visual Studio and some others. CTC++'s instrumentation overhead (size, speed) is remarkably low. The coverage/execution profile data is can be reported in textual, HTML (hierarchical, color-coded, information shown along with the actual source code), XML, and in Excel form.

CTC++ can be used interactively by developers on daily basis, and as integrated to build scripts.

With CTC++ Host-Target add-on coverage measuring is possible at various embedded targets. Sometimes CTC++ Bitcov add-on may be needed, if the target is of "micro-controller scale" and has limited memory.

Testwell CMT++, Complexity Measurement Tool for C/C++/C#
CMT++ is a simple to use tool for measuring C, C++ and C# source files for their size, complexity and maintainability properties. CMT++ provides the following metrics:

• lines of code counts (physical, program, comment, blank)
• McCabe Cyclomatic number (program flow complexity)
• Halstead measures (program volume, error-proneness, time to understand, etc.)
• Maintainability Index

Testwell CTA++, C++ Test Aider
CTA++ is a tool for automating unit testing of C++ classes, libraries and subsystems. CTA++ is simple to use and provides very powerful features helping the tester to build the testing environments and running the tests.

CTA++ implements the test execution framework as a test bed program. The CTA++ test beds contain the following parts:

• test driver: developed by the tester in C++ as the scripting language, and using the CTA++ system services, modeled into test cases (functions) that are "registered" to the test driver and "run" by it
• code under test: the actual C++ (or C) code under test, which is called from the test case functions
• stubs (optional): CTA++ supported implementations of the functions of other software components that the code under test may call, and whose behavior can be controlled when running the test cases.
• test data file (optional): a CTA++ capability where test data can be inputted to the test cases from a textual test data file
