Run the tests

Running the C++ tests

Run all tests

To run all the C++ tests you can use following command:

./yb_build.sh release --ctest

If you omit release argument, it will run java tests against debug YugabyteDB build.

Run specific tests

To run a specific test, for example the util_monotime-test test, you can run the following command:

./yb_build.sh release --cxx-test util_monotime-test

To run a specific sub-test, for example the TestMonoTime.TestCondition sub-test in util_monotime-test, you can run the following command:

./yb_build.sh release --cxx-test util_monotime-test --gtest_filter TestMonoTime.TestCondition

Running the Java tests

Run all tests

Given that you've already built C++ and Java code you can run Java tests using following command:

./yb_build.sh release --scb --sj --java-tests

If you omit release argument, it will run java tests against debug YugabyteDB build, so you should then either build debug binaries with ./yb_build.sh or omit --scb and then it will build debug binaries automatically.

Run specific tests

To run specific test:

./yb_build.sh release --scb --sj --java-test org.yb.client.TestYBClient

To run a specific Java sub-test within a test file use the # syntax, for example:

./yb_build.sh release --scb --sj --java-test org.yb.client.TestYBClient#testClientCreateDestroy

Viewing log outputs

You can find Java tests output in corresponding directory (you might need to change yb-client to respective Java tests module):

$ ls -1 java/yb-client/target/surefire-reports/
TEST-org.yb.client.TestYBClient.xml
org.yb.client.TestYBClient-output.txt
org.yb.client.TestYBClient.testAffinitizedLeaders.stderr.txt
org.yb.client.TestYBClient.testAffinitizedLeaders.stdout.txt
…
org.yb.client.TestYBClient.testWaitForLoadBalance.stderr.txt
org.yb.client.TestYBClient.testWaitForLoadBalance.stdout.txt
org.yb.client.TestYBClient.txt

Note

The YB logs are contained in the output file now.

YSQL Java tests

YSQL java tests are in java/yb-pgsql/src/test/java/org/yb/pgsql/. They can be run as:

./yb_build.sh --java-test org.yb.pgsql.TestPgTruncate

Some of those tests, TestPgRegress*, use the PostgreSQL regress test framework: src/postgres/src/test/regress.
They should each correspond to a schedule (e.g. java/yb-pgsql/src/test/java/org/yb/pgsql/TestPgRegressArrays.java references src/postgres/src/test/regress/yb_arrays_schedule) that is run by our modified version of pg_regress.

Each schedule has a serial order of files to run. For example, the yb_arrays_schedule will first run build/latest/postgres_build/src/test/regress/sql/yb_pg_int8.sql and output to build/latest/postgres_build/src/test/regress/results/yb_pg_int8.out because the first test: line in yb_arrays_schedule is test: yb_pg_int8.
This will be compared with build/latest/postgres_build/src/test/regress/expected/yb_pg_int8.out for pass/fail.
Note the build/latest/postgres_build prefix. The source files (src/postgres/src/test/regress/sql/foo.sql) get copied there (build/latest/postgres_build/src/test/regress/src/foo.sql).
If a build fails to pick up the changes and fails to copy them, you can remove build/latest/postgres_build to force a recopy or copy them yourself manually.

Tips

If you want to quickly run specific sql files, you can create a dummy java file and dummy schedule with that one test in it.
Use the naming convention (some older files haven't adopted it yet, but should):
- src/postgres/src/test/regress/sql/foo.sql: unchanged from original PostgreSQL code
- src/postgres/src/test/regress/sql/yb_foo.sql: completely new file (for example, with new features)
- src/postgres/src/test/regress/sql/yb_pg_foo.sql: modified version of original PostgreSQL foo.sql (e.g. for compatibility edits)
- The goal here is to reduce the difference between foo.sql and yb_pg_foo.sql, when possible.
When creating new yb_pg_foo.{out,sql} files and adding them to one of our schedules, sort them into the schedule using src/postgres/src/test/regress/serial_schedule as reference. Schedules parallel_schedule and serial_schedule should be untouched as they are from original PostgreSQL code.
