Presto Native Tests

This module contains end-to-end tests that run queries from test classes in the presto-tests module with Presto C++ workers. Please build the module presto-native-execution first.

The following command can be used to run all tests in this module:

mvn test 
    -pl 'presto-native-tests' 
    -DstorageFormat=PARQUET
    -DsidecarEnabled=true
    -Dtest="com.facebook.presto.nativetests.Test*" 
    -Duser.timezone=America/Bahia_Banderas 
    -DPRESTO_SERVER=${PRESTO_HOME}/presto-native-execution/cmake-build-debug/presto_cpp/main/presto_server 
    -DWORKER_COUNT=${WORKER_COUNT} -T1C

Update the following JVM arguments:

1. PRESTO_SERVER: Points to the Presto C++ worker binary, presto_server.
2. storageFormat: File format of TPC-H tables used in tests, DWRF and PARQUET formats are supported. This argument is optional and test tables are created in PARQUET format by default.
3. sidecarEnabled: Indicates whether the native sidecar plugin should be installed on the coordinator and the workers configured as sidecars in the native query runner used for tests. This argument is optional and sidecar is enabled by default.

Adding new tests

Presto C++ currently does not have the same behavior as Presto for certain queries. This could be because of missing types, missing function signatures, among other reasons. Tests with these unsupported queries are therefore expected to fail and the test asserts the error message is as expected.

Issues should also be created for the failing queries, so they are documented and fixed. Please add the tag presto-native-tests for these issues. Once all the failures in a testcase are fixed, the overriden test in this module should be removed and the testcase in the corresponding base class in presto-tests would be the single source of truth for Presto SQL coverage tests.
