+### To run a separate test manually on a built UI:
+1. Add the black-box-tests module in the [pom.xml](../pom.xml) or add as a Maven project
+2. Add Vm Option "*-DrunLocal=true -Dtb.baseUiUrl=http://localhost:4200/*" in "Run" -> "Edit Configuration" -> "Edit Configuration Templates" -> "TestNG"
+3. To run a specific test, go to the test class in the [UI tests package](../black-box-tests/src/test/java/org/thingsboard/server/msa/ui/tests) and run the test. Alternatively, go to the [resources](../black-box-tests/src/test/resources) in the black-box-tests module and run the test suite that you need.
