Installing the Unix Parallel Unit Test Harness

Installation

Download the latest RPM distributable of the MettleCI parallel Unit Test Harness (see Accessing the MettleCI Software Distribution). The rest of these instructions assume this is located in your user’s $HOME directory.
From that directory, install the package from the shell of your DataStage Development Engine using Red Hat Package Manager (RPM).
CODE
```
sudo rpm -U dm-unittest-harness-x.x-x.noarch.rpm
# or for AIX...
sudo rpm -U dm-unittest-harness-x.x-x.noarch.rpm --ignoreos
```
Verify that your rpm package installation has been successful. Note that this command uses the package name ('dm-unittest-harness') and not the RPM filename ('dm-unittest-harness-x.x-x.noarch.rpm').
CODE
```
sudo rpm -V dm-unittest-harness
.....UG..    /opt/IBM/InformationServer/Server/DSComponents/bin/dm-unittest-harness-1.0-219.jar
.....UG..    /opt/IBM/InformationServer/Server/PXEngine/bin/osh-dm
```
If your MettleCI licence file has not already been installed by the Workbench then copy your MettleCI licence file into the location /opt/dm/mci/mettleci.lic

Log into your development DataStage Engine(s) and navigate to your DataStage project folder. This would typically be:
CODE
```
/opt/IBM/InformationServer/Server/Projects/<Your Existing Project>
```

Add the following Environment variable definition to the DSParams file under the [EnvVarDefns] section:

CODE

DM_ENABLE_UNIT_TESTING\MettleCI\-1\List/Disabled//Test//Intercept/\Disabled\3\Project\Unit Testing Configuration\

This will make the following Environment Variable available to add to the DataStage jobs for which you wished to enable unit testing:

Add the same entry described above to the DSParams for your ‘Template’ project, located in directory:
CODE
```
/opt/IBM/InformationServer/Server/Template
```

You can uninstall the MettleCI Unit Test Harness package like any other RPM package:
CODE
```
sudo rpm -e dm-unittest-harness
```
