| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This article presents a method of reinforcing generation of instruction sequences in random testing of the Android virtual machine (VM). A mutation based random test generation method, in which input DEX (Dalvik Executable) files are generated by randomly mutating some bytes in existing valid DEX files, ends up with low efficiency because invalid DEX files are rejected by the VM's verifier. On the other hand, in a generation based method, which generates only valid DEX files that pass the verifier, did not incorporate enough number nor enough variation of instructions and class fields. In this article the latter method is extended to provide test files with larger number and variation of instruction and class fields. More than one methods are generated in a byte code to increase the total number of instructions in a file. A top-down generation procedure is employed instead of the bottom-up one to make it easier to afford variety of instructions and operands. The field information in the file header is modified to randomly change the types and modifiers of class fields. A test system has been implemented in Perl 5 and the VM of Android 9.0 have been tested. Although no error has been detected so far, it is expected that the tests provides a wider coverage. | |
