Before running tests, ensure all steps in the BUILDING.md have been performed.

Tests are broken up into five types - unit, integration, distributed, acceptance, and upgrade. They can be executed using the following commands from the Geode repository root directory:

• Unit tests: generally test a single class and run quickly
  ./gradlew test
• Integration tests: involve inter-operation of components or subsystems
  ./gradlew integrationTest
• Distributed tests: involve multiple members of a distributed system.
  ./gradlew distributedTest
• Acceptance tests: test Geode from end user perspective
  ./gradlew acceptanceTest
• Upgrade tests: test compatibility between versions of Geode and rolling upgrades
  ./gradlew upgradeTest

To run an individual test, you can either

1. Run the test in your IDE
2. Run from terminal by specifying the sub-project and test type:
   ./gradlew project:testType --tests testName
   For example:
   ./gradlew geode-core:test --tests ArrayUtilsTest
./gradlew geode-core:distributedTest --tests ConnectionPoolDUnitTest

To run a specific category of tests (eg: GfshTest):
./gradlew project:testType -PtestCategory=fullyQualifiedTestClassName
For example:
./gradlew geode-core:distributedTest -PtestCategory=org.apache.geode.test.junit.categories.GfshTest

Available categories can be found in the geode-junit/src/main/java/org/apache/geode/test/junit/categories in the Geode repository.

Test results can be viewed by navigating to build/reports/combined in the Geode repository, then opening the index.html file in your browser.
