             Summary: SparkR tests should use more specific expectations than expect_true
                 Key: SPARK-7714
                 URL: https://issues.apache.org/jira/browse/SPARK-7714
             Project: Spark
          Issue Type: Improvement
          Components: SparkR
            Reporter: Josh Rosen


SparkR's test use testthat's {{expect_true(foo == bar)}}, but using expectations like {{expect_equal(foo, bar)}} will give informative error messages if the assertion fails.  We should update the existing tests to use the more specific matchers, such as expect_equal, expect_is, expect_identical, expect_error, etc.

See http://r-pkgs.had.co.nz/tests.html for more documentation on testtthat expectation functions.
