FAQs and Troubleshooting

In this section:

How can I get quick access to information about usage on the command line?

Use the -help command line switch:

cpptestcli.exe -help

What if C/C+test is not available in the UI when installed in Eclipse that runs on Java 11 or higher?

If your Eclipse is configured to use Java 11 or higher, it may require additional dependencies to be downloaded from software update sites. Ensure that Eclipse is configured to automatically contact all update sites when you install C/C++test.
If C/C++test is not available in your IDE after installation, you may need to install the Apache Geronimo Activation Plug-In. The current builds provided by the Eclipse Orbit Project are available at: https://download.eclipse.org/tools/orbit/downloads:

Select the build appropriate for your Eclipse version.
Copy the URL of the Orbit build repository.
Select Help> Install New Software from the Eclipse menu.
Click Add and paste the URL to specify the location of the Orbit build repository.
Expand All Orbit Bundles.
Select Apache Geronimo Activation Plug-In.

How do I fix a failed installation while integrating C/C++test with Visual Studio with a registry key suffix specified?

Providing a long registry suffix may lead to installation failure due to the path length limitation on Windows. To ensure that C/C++test is successfully installed, specify a shorter registry suffix during installation.

Why do I get notified that Parasoft Plugin or its components are slowing down Visual Studio 2017 or 2019 on startup?

In Visual Studio 2017 and 2019, performance management monitors and manages extensions that can affect startup time. As a result, a pop-up alert may appear when Parasoft Plugin is installed to indicate that Visual Studio startup time has increased. You can click the 'Manage performance' link in the pop-up window to review the startup times and disable displaying the alert.

Why are some Parasoft options not available in the Solution Explorer context menu in Visual Studio 2017?

To have access to all Parasoft options in the Solution Explorer context menu, ensure that one of the following workloads is installed with your Visual Studio 2017:

Desktop development with C++
Universal Windows Platform development or .NET desktop development

Run the Visual Studio Installer.
Select the appropriate workloads when prompted.

Why does Visual Studio 2015 not display code markers?

If the Parasoft DTP Plugin for Visual Studio is reinstalled, Visual Studio 2015 may fail to display code markers that indicate analysis findings or code coverage in the editor. This is caused by a Visual Studio known issue (see MEFCache bug breaks text adornments in any package for details).

To ensure that code markers are properly shown, clear the Visual Studio MEF cache each time you reinstall or updated the Parasoft DTP Plugin. Use one of the following options:

Use the Clear MEF Component Cache extension that will automatically clear the MEF cache (download here).
Manually delete the cache directory. Depending on your installation details, the cache directory may be available in the following locations:
- If the Plugin has been installed with the default options: %localappdata%\Microsoft\VisualStudio\14.0\ComponentModelCache
- If the Visual Studio registry suffix has been specified with the <SUFFIX> parameter during installation: %localappdata%\Microsoft\VisualStudio\14.0<suffix_name>\ComponentModelCache

What if some characters fail to be properly displayed in C/C++test reports?

Reports generated by Parasoft products require a sans-serif font to be available in your environment. If your report fails to correctly display some characters, such as national characters, ensure that a sans-serif font is installed on your system.

How can I prevent my machine ID from floating?

Changes in the network environment may affect the interface that is used to compute your machine ID and result in machine ID instability. You can use the PARASOFT_SUPPORT_NET_INTERFACES environment variable to specify a stable interface and prevent the machine ID from floating.

Set up the PARASOFT_SUPPORT_NET_INTERFACES environment variable.
Set the variable value to a stable Ethernet network interface. Do not use virtual, temporary or loopback interfaces.
- On Windows: Set the value to the MAC address of your network card. You can use the ipconfig -all command to obtain the address. For example:
```
SET PARASOFT_SUPPORT_NET_INTERFACES=00-10-D9-27-AC-85
```
- On Linux: Set the value to one of the network interfaces from the "inet" or "inet6" family. You can use the ifconfig command to obtain the list of available interfaces. For example:
```
export PARASOFT_SUPPORT_NET_INTERFACES=eth1
```

If the problem persists, you can obtain diagnostic information by setting up the environment variable PARASOFT_DEBUG_NET_INTERFACES and setting its value to true. This will print to the standard output the checking procedure that can be shared with technical support, as well as the interface that is used to compute your machine ID. The interface will be marked with the [SELECTED] prefix.

How can I work with C/C++test via proxy?

Typically, if you connect through a proxy server, you need to configure the connection by passing protocol-specific system properties to the JVM – using the -D command line option.

To work with C/C++test, ensure that the system properties for the HTTPS protocol are configured. At a minimum, you must configure https.proxySet=true, https.proxyHost=[hostname], and https.proxyPort=[port number]. If your proxy server requires authentication, you can configure your credentials with the https.proxyUser and https.proxyPassword properties.

Your command line may resemble the following:

java -Dhttps.proxySet=true -Dhttps.proxyHost=myserver.example.com -Dhttps.proxyPort=8080 -Dhttps.proxyUser=user1 -Dhttps.proxyPassword=MyPassword

In addition, you can configure the https.nonProxyHosts property to specify hosts where connection via proxy is not required.

If you use C/C++test on desktop with Eclipse, the proxy settings are automatically detected and do not need to be configured in the command line.

The proxy mode is not supported for Visual Studio.

What can I do if C/C++test reports a timeout during static analysis?

To ensure the analysis completes, you can do one of the following:

Increase the timeout limit by configuring the following option:
cpptest.analyzer.source.timeout=<TIMEOUT_IN_SECONDS>
See Configuring the Settings.
Disable the most time-consuming rules or metrics in your test configuration. The information about the times is included in the timeout message displayed on the console and in the report.
Contact Parasoft Support.
