Parth Chandra reassigned DRILL-2025:
------------------------------------
Assignee: Parth Chandra (was: Jacques Nadeau)
> some tests don't re-use Drillbits, seem slower than necessary
> -------------------------------------------------------------
>
> Key: DRILL-2025
> URL: https://issues.apache.org/jira/browse/DRILL-2025
> Project: Apache Drill
> Issue Type: Bug
> Components: Tools, Build & Test
> Reporter: Daniel Barclay (Drill/MapR)
> Assignee: Parth Chandra
> Fix For: 0.9.0
>
>
> Regarding tests that require running a Drillbit:
> In many (maybe even most) cases, a test class creates a Drillbit instance
> that is re-used by all the test methods in that class, so that each test
> method only takes about a second or less to run.
> However, there are a number of test classes that run much more slowly because
> the class doesn't reuse a Drillbit, so each of its test methods starts up and
> shuts down its own Drillbit instance, so each test method takes about 7 to 10
> seconds to run, making the test class and the overall test suite take
> considerably longer than seems necessary.
> Except for any test methods that really do need their own instance of
> Drillbit, those slower test classes should be adjusted to re-use Drillbits as
> many other classes do.
> Some slower, apparently non-sharing test classes are:
> org.apache.drill.jdbc.test.TestMetadataDDL (30 methods)
> org.apache.drill.jdbc.test.TestViews (20 methods)
> org.apache.drill.jdbc.test.TestJdbcQuery (20 methods)
> org.apache.drill.jdbc.test.TestJdbcDistQuery (12 methods)
> org.apache.drill.exec.physical.impl.TestDecimal (6 methods)
> org.apache.drill.exec.record.vector.TestDateTypes (6 methods)
> org.apache.drill.jdbc.test.TestHiveStorage (5 methods)
> org.apache.drill.exec.physical.impl.TestExtractFunctions (5 methods)
> org.apache.drill.exec.expr.ExpressionInterpreterTest (4 methods)
> org.apache.drill.exec.fn.impl.TestDateFunctions (3 methods)
> org.apache.drill.exec.physical.impl.TestDistributedFragmentRun (3 methods)
> org.apache.drill.exec.physical.impl.window.TestWindowFrame (3 methods)
> org.apache.drill.exec.physical.impl.TestSimpleFragmentRun (3 methods)
