Test a sample policy application
Testing a sample policy application involves validating policy as its applied to URIs.
Simulation allows you to validate URI requests before testing with the back end protected web resource.
- Configure application for simulation testing - Configure the application for simulation testing.
- Configure Access Gateway for debug and monitoring - Optionally configure Access Gateway to generate and display debug statements.
- Simulation testing - Perform header or policy simulation testing.
- Completed application testing - Perform normal application testing using production URLs.
- Disable Debug - Disable debug after testing.
This section covers testing using header based simulation and is only required if testing passing of values using application headers.
To configure an application for policy simulation testing:
- Navigate to the Access Gateway Admin UI console
- From the Topology tab or the Applications tab, open the application.
- Select the Settings pane.
- Expand the Essentials tab.
- Note the current value of Protected Web Resource.
- Change the Protected Web Resource field to:
Value Behavior https://policy.service.spgw When running a test, results in the display information related to application policy.
Copy and save the original back-end Protected Web Resource value.
- Expand the Advanced tab.
- Enable Debug mode.
When enabling Debug mode, ensure that the download log has also been set to level debug. Application debug events aren't visible in downloadable logs unless download logs are also configured to emit Debug level log events. See Manage log verbosity
- Click Done.
When debugging header-based applications, consider testing attributes with static known good values. For example, change dynamic IDP-based fields to static with known good values.
When debugging policy-based applications, test with no policy or open policy first.
You can optionally configure Access Gateway Management console to output a running display of all system log messages.
To enable this debugging mode and monitor Access Gateway:
- Open a terminal and use SSH to connect to the Access Gateway Management console (ssh oag-mgmt@gw-admin.<domain.tld>).
- Enter 4 - Monitoring.
- Enter 2 - Enable Debug.
- Enter 1 - Monitor logs. This starts the running display of all log messages.
Return to the Access Gateway Admin UI console console. You can test your application and examine the results in the running logs. Use[ctrl][c] to exit the log display.
See Monitor for more details about monitoring, including a list of available commands.
The debug logging level rapidly generates log messages. Always disable debug logging when you've finished examining the logs.
Not disabling debug logging can lead to rapid log file growth, which can result in errors due to lack of storage space.
Header and policy simulation testing involves temporarily replacing the Protected Web resource field in an application and then testing various target URLs, evaluating whether the headers and policies return the expected result.
To test an application using header or policy simulation:
- Configure the application for header or policy simulation testing as described in the Configure application for simulation testing section.
- Connect to the Access Gateway Management console and begin monitoring.
For details see the monitoring section in Troubleshooting Applications.
- Select the Applications tab.
- On the row containing the application, click Goto application > SP Initiated.
- Examine the header or policy information returned.
- Repeat for each protected URI.
- When complete disable debugging as described in the Disable debug section.
Completed application testing as required.
- The Applications tab, on the row containing the application, click Goto application > SP Initiated.
- Repeat testing using Goto application > IDP Initiated.
- Repeat testing using each specialized policy URI.
- If required, disable debugging.
Completed application testing as required.
If displaying debug statements at the command line:
- Return to the Access Gateway Management console.
- Enter [ctrl][c] to exit the log display.
- Enter 3 - Disable debug.
- Exit the command line console
If application debug is enabled:
- Return to the Access Gateway Admin UI console
- Navigate to the application being tested
- Expand the Setting sub tab.
- Expand the Essentials sub tab.
- Return the Protected Web Resource field back to its original value.
- Expand the Advanced sub tab.
- Set the Debug toggle to Disable.
- Save your changes.
