Published Release Notes

Unit testing support for more rule types

You can now create unit tests for the following additional rule types. You can also create assertions to validate activity status. The expanded rule types for unit testing enable developers to more thoroughly perform regression testing of their application, thereby improving application quality.

• Collection
• Declare expression
• Map value
• Report definition

For more information about unit testing rules, see Pega unit test cases.

Upgrade impact

With the four new rule types, unit test execution and unit test compliance metrics will change. Reports on automated unit testing of the customer application decrease due to the increased pool of supported rules.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, create Pega unit test cases for the newly supported rules to see updated and accurate unit test metrics.

View application quality metrics by data type

You can now view application quality metrics by data type on the Application Quality landing page. The new Data Types tab displays metrics for data types grouped by data objects, which enables you to more quickly understand the overall coverage of the application's integrations and interfaces.

For more information about data type metrics, see Application Quality landing page.

Scenario tests are reusable

Existing scenario tests are now reusable in different business scenarios. Before Pega 8.3, you had to create a new test every time a user interface or process flow changed significantly. Now, scenario tests are editable to help you maintain the test stack more effectively.

For more information, see Updating scenario tests.

Improvements for automated scenario testing

Test automation authors can group related scenario tests into suites. The scenario test suites can be run manually from the Scenario Testing landing page as part of purpose-specific tests such as smoke tests, regression tests, and outcome-based tests. Additionally, automation authors or release managers who monitor tests for an application can disable or quarantine unstable scenario tests so that they do not run.

For more information about creating and managing test suites for scenario testing, see Creating test suites for scenario testing.

Test coverage support for more rule types

Test coverage has been expanded to include the following rule types. Test coverage support for these rule types enables developers to more accurately measure the effectiveness of their tests.

• Collection
• Declare trigger
• Map value
• Navigation 
• Report definition
• Scorecard

For more information about test coverage, see Test coverage.

Upgrade impact

The new rule types may impact the test coverage metrics for your applications. Due to the increased number of supported rules, the reported test coverage percentage will decrease.

What steps are required to update the application to be compatible with this change?

Run your coverage reports after upgrading to see the latest metrics.

Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6

Upgrade impact statement

On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.

What is required to update the application to be compatible with this change?

Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.

For instructions about upgrading to Hazelcast 4.x, see one of the following topics:

• For near-zero downtime upgrades from Pega Infinity release 8.4.2 or later on Tomcat and PostgreSQL, see "Optional: upgrading to Pega Platform version 8.6: Upgrading to Hazelcast 4.x" in Near-zero downtime Upgrade Guide for Pega Platform version 8.4.2 and later for Tomcat and PostgreSQL.
• For all other upgrades, see "Optional: upgrading to Hazelcast 4.x" in the appropriate upgrade guide.

Extend PegaUnit setup and cleanup capabilities using custom fixtures

The set up and clean up capabilities in the PegaUnit framework are now customizable through the use of custom fixtures. Custom fixtures extend the default testing functionality and allow you to define and implement specific runtime actions, such as running a specific test case during set up or sending an email after testing has completed execution. 

For more information, see Setting up and cleaning the context for a test case or test suite. 

Improved indexing of StringList and StringGroup property types

Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.

Upgrade impact

After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed. 

What steps are required to update the application to be compatible with this change?

On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.

For more information, see Indexing class data.
