--------------------------------------

             Summary: [Java] Create static factory methods for common array types of testing.
                 Key: ARROW-6930
                 URL: https://issues.apache.org/jira/browse/ARROW-6930
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: Micah Kornfield


There is a lot of verbosity in the construction of Arrays for testing purposes (multiple lines of setSafe(...) or set(...).  We should start adding some static factory methods to make test setup clearer  and more concise.  A strawman proposal for BigIntVector might look like:

 

static BigIntVector create(String name, BufferAllocator allocator, Long... values).

 

Usage would be something like:

 

try (BigIntVector input = BigIntVectorCreate("sample_data", allocator, 1235L, null, 456L),

      BigIntVector expected = BigIntVectorCreate("sample_data", allocator, 1L, null, 0L),) {

   output = doSomethingWith(input);

   assertThat(output).isEqualTo(expected);

}
