Embedded software testing pdf

The first complete description of all necessary ingredients of a testing process. It includes classic as well as modern test design techniques. Behandelt werden u. Methodisches Testen von Programmen. Der Klassiker zum Thema Softeware-Test, bereits in der 7. Es ist ein Handbuch zur Optimierung des methodischen Testens in der Praxis. Designed for testers working in the ever-expanding world of "smart" devices driven by software, the book focuses on attack-based testing that.

Books about Eine Technologie fuer das durchgaengige und automatisierte Testen eingebetteter Software. Software Engineering for Embedded Systems. State of the art techniques and best practices in the development of embedded software apply not only to high-integrity devices such as those for safety-critical applications like aircraft flight controllers, car braking systems or medical devices , but also to lesser-integrity applications when the need to optimize the effectiveness of the.

The tool developed M. Delamaro [12] developed a coverage testing tool for by Yongyun Cho makes it easy for test engineer to generate mobile device software. Testing conducted shortage of multi-round automatic testing. Test engineer on mobile device is difficult since elements such as memory would need to take extra time to write test script and test limitations, persistent storage, and network connection driver.

The tool allows the testing of mobile applications not only III. Testing code is being executed on mobile devices, trace data is functions provided by ATEMES system include coverage transferred through network link to monitor the testing.

This testing, unit testing, performance testing and race condition approach can help reducing workloads from testing mobile testing. In this paper, we focus on coverage testing and unit devices. Presenting test result on visualized interface keeps testing.

System module is shown as Figure 1. System test engineer informed of how many lines are yet to be architecture layers are shown as Figure 2. Functions of executed. Automation such as generating test input data and respective modules are detailed as follows sections. Jooyoung Seo [13] proposed a tool Justitia to test embedded software. Debugging can be executed for test engineer to set the breakpoints on the interface. However, more times are needed to conduct testing if test engineers are not quite experienced in testing or they do not know architecture of the entire embedded system.

The focal function of Justitia is automatically detecting errors on interface of program. The existing monitoring and debugging technology of emulator is combined to test embedded software. By defining embedded software interface pattern, an automated scheme is created to find location of source code interface. The testing tool can automatically generate test case interface test feature, location of interface, symbol to be monitored at the interface, input data, and expected output and execute test case using emulation testing technology.

Further, the system can support memory test and Figure 1. System modules interrupt test. After completing testing, the result of test coverage and interface error can be presented on visualized A.

The main focus of the system is on single testing. The bottom layer is hardware platform layer. Platforms of target-side can be embedded software testing tool. The 2nd layer is OS layer. It is a sides, we have used Linux operation system. The 3rd layer is performance testing tool indepedent from extra hardware the library layer we adopted, including GCOV [15], Cppunit support. On host-side, this tool provide graphic user interface [16], and Jfreechart [17]. The 4th layer is application layer for test engineer and software testing is executed on target- constructed by ATEMES system modules.

The 5th layer is the side of embedded system platform which include memory test, graphic user interface layer of host-side. In addition, Yongyun Cho has designed a xml-based DTDs Document type definitions to increase test script usability and reusability. Test case framework example Figure 2. The main source code so that data can be collected during the execution function of HSATM module is to automatically generating test of target program and report to host-side during runtime.

Figure 4 shows the test driver and instrumented source code to executable files. The executable files and test input data are then delivered to target-side for execution. The major task of TSATM module is to trigger test driver to execute or terminate testing tasks, and can monitor profiler to collect testing data. It can return collected testing information to host-side during runtime. Figure 6 shows the example of test driver automatically generated.

Figure 3. Step 2: With the aid of information provided by requirement specification files, PRPM conducts parsing source code which has been read and extracts program function name and parameter, internal structure of program, and other information. Step 3: PRPM analyzes the extracted information based on the parsed data by step 2. Test case is generated automatically after analysis, or new test case test input data is generated based on the test result feedback by POPM during testing.

Step 4: PRPM processes the extracted information based on the parsed data by step 3. Analysis is conducted according to the intended testing items. Instrumented source code is automatically generated after analysis. Figure 6. To make it generated from PRPM. Graphical interface is adopted to Step 8: HSATM compiles the instrumented source code present test result during runtime or the end of testing. The and test driver to target-side executable files and modules are composed of 2 parts, test log analyzer and test uploads to TSATM.

The system module is shown as Figure 7. Step Repeat step 3 to step 10 until testing termination conditions are met. Step POPM presents test result to testing engineer. Figure 7. POPM module B. Multi-round automatic testing scenario is selected to describe how the system operates. The scenario of multi-round automatic testing is parsing source code, generating the intended data including test case, test input data, instrument code segment and test driver, automatically executing testing, collecting and parsing test log file, automatically executing the next round testing Figure 8.

Coverage Testing Mechanism Table 1. Output: coverage. Process of multi-round coverage add 0 to flag. After each IV. Automatic multi-round Algorithm is shown as Table 1. Test experiment result is presented in visualized way. Software and hardware platforms for the experiments are detailed as follows: 1. Target-side OS platform: Linux Kernel 2. Coverage Testing Experiment 1 Experiment of automatic coverage testing 13 programs of data structures are selected as the target testing program, among which most of input data types are array of structure type.

Random testing method is applied as the testing environment to generate test input data. For each function, each round generates 3 sets of input data, and each function is planed to execute 20 rounds of testing.

The system can record history data for each round, including line coverage, branch coverage, executing time and information of failed test case. When testing engineer input test data and result, the then coverage is hardly increased beyond that.

The bottleneck ATEMES will automatically generate test case programs and lies in that the algorithm we have adopted is random testing test driver programs, conducts automatic cross-compilation, method, higher coverage is can be foreseen if other algorithms uploads test package to ARM 11 MPCore platform and starts were adopted.

Test result logs can be transferred to host-side for simultaneous analysis during runtime. On the right side of the figure, unit test result is shown by pie chart. Figure The line and branch coverage testing result Table 2.

Line coverage Figure Experiment of unit testing round test result have provided another solution for testing engineer to save his effort as well.
