- Normal unit test: These are used by testing a particular component of Hive.
- We just need to add a new class (name must start with "Test") in */src/test directory.
- We can run "ant test -Dtestcase=TestAbc" where TestAbc is the name of the new class. This will test only the new testcase, which will be faster than "ant test" which tests all testcases.
- A new query: If the new feature can be tested using Hive command line, we just need to add a new *.q file and a new *.q.out file:
- If the feature is added in ql
- Add a new XXXXXX.q file in ql/src/test/queries/clientpositive
- Run "ant test -Dtestcase=TestCliDriver -Dqfile=XXXXXX.q -Doverwrite=true -Dtest.silent=false". This will generate a new XXXXXX.q.out file in ql/src/test/results/clientpositive.
- If you want to run multiple .q files in the test run, you can specify comma separated .q files, for example- -Dqfile="X1.q,X2.q" . You can also specify a java regex, for example -Dqfile_regex='join.*'. (Note that it takes java regex, ie 'join.' and not 'join'). The regex match first removes the .q from the file name before matching regex, so specifying "join*.q" will not work.
- If you are using hive-0.11.0 or later, you can specify -Dmodule=ql
- If the feature is added in contrib
- Do the steps above, replacing "ql" with "contrib", and "TestCliDriver" with "TestContribCliDriver".
- If you are using hive-0.11.0 or later, you can specify -Dmodule=contrib
- If the feature is added in ql
