### Installation

There are two directory structures that utilize test suites in the IBM Developer Connection Device Driver Kit for OS/2. The TESTCERT substructure contains the executables and test cases; the TESTTOOL substructure contains the files required to change and rebuild the code for a particular test DLL .

The following procedure describes installation for running test cases:

1.Copy the executable and parallel port test case files from the IBM Developer Connection Device Driver Kit for OS/2 CD-ROM disc to the hard drive. All the executable (.EXE and .DLL) files can reside in one directory, such as \TESTPARA. Test-case script and command files can also be placed in this directory on the hard disk. If the target directory is C: \TESTPARA and the E drive contains the information from the IBM Developer Connection Device Driver Kit for OS/2 CD-ROM disc, then use the following commands to copy the parallel port test suite:

       [C:\]md testpara

       [C:\]cd testpara

       [C:\testpara]copy e:\ddk_x86\testcert\inputout\function\parallel\*

       [C:\testpara]copy e:\ddk_x86\testcert\general\ddtt\*

2.Add the C:\TESTPARA to the LIBPATH and PATH in the CONFIG.SYS file.

3.For script testcase REQEX.SCR, which requests and releases exclusive access, a generic driver named GENDRV.SYS must be installed. Edit your system's CONFIG.SYS file and add the following line:

       DEVICE=c:\testpara\gendrv.sys

4.Reboot your machine so the new LIBPATH entry and DEVICE statement take effect.
