Key Workflows

Application Testing

1. Locate the TestSuiteService on the Project.
2. Access ApplicationTestSets composition.
3. Manage ApplicationTestSet and TestCase objects.
4. Execute tests via TestCaseExecutor.

Style Guide

1. Access StyleGuideSystemGroups on the TestSuiteService.
2. Manage RuleSet objects and compositions.
3. Execute checks via RuleSetExecutor.

System Testing

1. Access SystemTestSystemGroups on the TestSuiteService.
2. Manage SystemTestCase objects.
3. Execute tests via SystemTestCaseExecutor.

Enforcement

1. Verify the existence of the target PLC software or OPC UA server before running tests.
2. Properly handle test failures using the TestResults and TestResultsMessage properties.
