• Specify dbCreateTable() and dbAppendTable() (#169).
• New unquote_identifier_table_schema test: Identifiers of the form table.schema can be processed with dbUnquoteIdentifier().
• Fix has_completed_statement test (#176).

Testing infrastructure

• Document how to run tests externally and how to debug tests (#165).
• test_*() gain new run_only = NULL argument that allow restricting the tests to be run with a positive match. test_some() uses run_only instead of constructing a regular expression with negative lookahead. This helps troubleshooting a single test with testthat::set_reporter(DebugReporter$new()) .

• Add specification for dbColumnInfo() (r-dbi/DBI#75).
• Add specification for dbListFields() (r-dbi/DBI#75).
• Test that named parameters are actually matched by name in dbBind(), by shuffling them (#138).
• Explicitly specify default row.names = FALSE for dbReadTable() and dbWriteTable() (#139).

• Add test for dbQuoteIdentifier(): “The names of the input argument are preserved in the output” (r-lib/DBI#173).
• Blob tests now also read and write zero bytes (00).
• Add string encoded in Latin-1 to the character tests.
• Added test for dbIsValid() on stale connections.

Removed checks

• Don’t test selecting untyped NULL anymore.
• Full interface compliance doesn’t require a method for dbGetInfo(DBIDriver) for now.
• Remove "cannot_forget_disconnect" test that fails on R-devel (#150).

• Implement POSIXlt bind test correctly.
• Improve error detection for dbBind().
• Redesign tests for dbBind(), now queries of the form SELECT CASE WHEN (? = ?) AND (? IS NULL) THEN 1.5 ELSE 2.5 are issued. The original tests were inappropriate for RMariaDB, because an untyped placeholder is returned as a blob.
• Transaction tests now use dbWriteTable() instead of dbCreateTable(), because some DBMS don’t support transactions for DML.
• Fix timestamp tests for RMariaDB.
• Fix string constants.
• The "roundtrip_timestamp" test now correctly handles timezone information. The output timezone is ignored.
• Clear result in spec_meta_get_info_result (#143).

• Minor fixes.

Tweaks

• New tweak blob_cast allows specifying a conversion function to the BLOB data type.
• New is_null_check tweak that allows specifying a function that is used when checking values for NULL. Required for RPostgres.
• New list_temporary_tables tweak that can be enabled independently of temporary_tables to indicate that the DBMS does not support listing temporary tables.

Infrastructure

• test_all() and test_some() return NULL invisibly.

Internals

• Added roundtrip test for time values (#14).
• Added tweaks for handling date, time, timestamp, … (#53, #76).
• Test that dbFetch() on update-only query returns warning (#66).

• row.names = FALSE is now the default for methods that read or write tables.
• Add NA to beginning and end of columns in table roundtrip tests (#24).
• Stricter tests for confusion of named and unnamed SQL parameters and placeholders (#107).
• Also check names of all returned data frames.
• The return value for all calls to dbGetQuery(), dbFetch(), and dbReadTable() is now checked for consistency (all columns have the same length, length matches number of rows) (#126).
• Removed stress tests that start a new session.
• Allow hms (or other subclasses of difftime) to be returned as time class (#135, @jimhester).
• Test that dates are of type numeric (#99, @jimhester).

• DBItest_tweaks class gains a $ method, accessing an undefined tweak now raises an error.
• The arguments of the tweaks() function now have default values that further describe their intended usage.
• New with_closed_connection(ctx = ctx, ), with_invalid_connection(ctx = ctx, ), with_result() and with_remove_test_table() helpers, and expect_visible(), expect_inbisible_true(), and expect_equal_df() expectations for more concise tests.

DBItest 1.2 (2016-05-21)

• Infrastructure
  • Support names for contexts (@hoesler, #67).
  • The skip argument to the test functions is now treated as a Perl regular expression to allow negative lookahead. Use skip = "(?!test_regex).*" to choose a single test to run (#33).

  • current_needs_parens – some SQL dialects (e.g., BigQuery) require parentheses for the functions current_date, current_time and current_timestamp.

• New tests
  • dbGetInfo(Result) (rstats-db/DBI#55).
  • dbListFields() (#26).
  • New package_name test in test_getting_started().
