How it Works

Why VectorCAST/C++
Generally, software component testing requires generating at least one line of test code (in the form of stubs, drivers, and test data) for each line of application code to be tested. The necessity to create this “disposable” test software is the main reason why manual component testing is so expensive and inefficient.  Test software not only has to be written but also has to be debugged to ensure that it performs as expected.  With VectorCAST/C++, component testing can be performed without writing a single line of test code.

Integrated Code Coverage
Without a code coverage tool, it is difficult to determine which portions of the source code have been exercised during testing. VectorCAST/C++ provides an integrated code coverage utility that allows you to gauge the effectiveness of your component testing by reporting on the source code statements or decision points exercised during individual or multiple test runs. Code coverage data can also be shared with VectorCAST/QA to produce combined coverage reports that reflect unit, integration, and system testing.

Testing is Repeatable
Once test cases have been developed, you can use VectorCAST/C++ to automatically run test cases against successive versions of the source code.   The management of test execution and the cataloging of test results are automatic. Comparing results of the same test cases against new software versions, prior to system integration, results in fewer surprises caused by “one small change” to a software component.

Supports Integration Testing
Multiple units can be tested in a single VectorCAST/C++ test environment. This allows you to create complex test scenarios that stimulate multiple functions across multiple units.

Compiler Integration
All VectorCAST/C++ generated test harness components are automatically compiled and linked using your compiler.  An interface to your compiler’s debugger is also provided so that you can run test cases under control of the debugger.

Test Driven Development
VectorCAST/C++ supports Agile and Test Driven Development methodologies. Test case development now becomes the initial activity once the design is complete. This allows you to construct all unit tests prior to any application code being developed. Initially, unit tests will fail due to the absence of source code. But, with the incremental development of code for individual units, the unit tests will begin to pass. The unit test suite can then be regression tested automatically.

Embedded Target Testing
VectorCAST/C++ when used in conjunction with VectorCAST RSP allows testing directly on your embedded target system. VectorCAST RSP is integrated with the cross compiler and RTOS, making it the perfect tool for testing real-time applications. Tests may be developed in a host environment and then re-executed on an embedded target to verify target and cross-compiler performance.

Integrations
VectorCAST is designed to work with your existing software development toolchain and build system. This allows projects to test in multiple environments and to use the compiler, operating system and hardware appropriate for that environment. This means you can use VectorCAST for both host-based development testing as well as testing in your final embedded hardware target environment.

Compilers

C and C++ Supported Compilers

For C and C++, VectorCAST is user-configurable for the compiler that you are using. If the compiler you are using is not on the list of supported C/C++ compilers, you simply need to configure the compile and link commands for your compiler.
