Tips to Evalute Embedded Software Testing Tools
The software testing process is used to detect the errors hidden in the programming codes. Embedded systems software testing shares much in common with application software testing. There are many ways to evaluate the testing tools of embedded software.
The speed of the testing process can be easily enhanced with the help of the testing tools. Hence, there should be good software experts chosen for this purpose. On the other hand, in order for checking how the working of an application and also the codes being used in programming, the automation is required.
Embedded Software Testing Process:
* Define test objectives and functional testing strategy.
* Identify embedded software interfaces.
* Identify input and output signals across these interfaces.
* Identify platform compatibility testing requirements.
* Define manual test cases, test data and expected results.
* Test execution, test management and defect resolution.
* Develop test harness using embedded tools and emulators for automated testing.
* Test Metrics and reporting
There are varieties of functionalities that the embedded software testing tools provide with different tools. Some of the common tools are as follows:
Parser: The parser module makes you understand the code. The intermediate representation is created by this tools after it goes through the code.
CodeGen: This tool is much important for constructing the source code of test harness by making use of ‘parse data’.
Test Harness: Most of the features of all prominent tools will be highly affected from the functions that the software expert carry-out with the help of harness tools.
Compiler: The compiler module allows the test tool to invoke the compiler to compile and link the test harness components.
Target: The target module allows tests to be easily run in a variety of runtime environments including support for emulators, simulators, embedded debuggers, and commercial RTOS.
Test Editor: The test editor allows the user to use either a scripting language or a sophisticated graphical user interface (GUI) to setup preconditions and expected values (pass/fail criteria) for test cases.
Coverage: The coverage module allows the user to get reports on what parts of the code are executed by each test.
Reporting: The reporting module allows the various captured data to be compiled into project documentation.
Automated: tools will address each of the functional areas or modules listed in the previous section. Tools in this class will not require manual hand coding and will support all language constructs as well a variety of target deployments.
