DBItest 1.7.0

Specifications

• 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()) .

Internal

DBItest 1.5-1

• Remove "cannot_forget_disconnect" test that fails on R-devel (#150).

v1.5

Finalize specification. Most tests now come with a corresponding prose,
only those where the behavior is not finally decided don't have a prose
version yet (#88).

New tests

• Test behavior of methods in presence of placeholders (#120).
• Test column name mismatch behavior for appending tables (#93).
• Test that dbBind() against factor works but raises a warning (#91).
• Test roundtrip of alternating empty and non-empty strings (#42).
• Test multiple columns of different types in one statement or table
  (#35).
• Test field.types argument to dbWriteTable() (#12).
• Added tests for invalid or closed connection argument to all methods
  that expect a connection as first argument (#117).
• Enabled test that tests a missing dbDisconnect().
• Add test for unambiguous escaping of identifiers
  (r-dbi/RSQLite#123).
• Reenable tests for visibility (#89).
• Fix and specify 64-bit roundtrip test.
• 64-bit integers only need to be coercible to numeric and character
  (#74).
• 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).

Adapted tests

• NULL is a valid value for the row.names argument, same as FALSE.
• A column named row_names receives no special handling (#54).
• A warning (not an error anymore) is expected when calling
  dbDisconnect() on a closed or invalid connection.
• 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).
• Replace POSIXlt by POSIXct (#100, @jimhester).
• Use "PST8PDT" instead of "PST" as time zone (#110, @thrasibule).
• Added tests for support of blob objects (input and output), but
  backends are not required to return blob objects (#98).
• The logical_return, date_typed and timestamp_typed tweaks are
  respected by the bind tests.
• Fixed tests involving time comparison; now uses UTC timezone and
  compares against a difftime.
• Tests for roundtrip of character values now includes tabs, in addition
  to many other special characters (#85).
• Make sure at least one table exists in the dbListTables() test.
• Fix roundtrip tests for raw columns: now expecting NULL and not NA
  entries for SQL NULL values.
• Fix expect_equal_df() for list columns.
• Testing that a warning is given if the user forgets to call
  dbDisconnect() or dbClearResult() (#103).
• Numeric roundtrip accepts conversion of NaN to NA (#79).

Internal

• Fix R CMD check errors.
• Internal consistency checks (#114).
• Skip patterns that don't match any of the tests now raise a warning
  (#84).
• New test_some() to test individual tests (#136).
• Use desc instead of devtools (#40).
• All unexpected warnings are now reported as test failures (#113).
• 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(), with_invalid_connection(),
  with_result() and with_remove_test_table() helpers, and
  expect_visible(), expect_inbisible_true(), and expect_equal_df()
  expectations for more concise tests.

v1.4

DBI specification

• Use markdown in documentation.
• Description of parametrized queries and statements (#88).
• New hidden DBIspec-wip page for work-in-progress documentation.
• Get rid of "Format" and "Usage" sections, and aliases, in the specs.

Tests

• Not testing for presence of max.connections element in dbGetInfo(Driver) (r-dbi/DBI#56).
• Test multi-row binding for queries and statements (#96).
• New ellipsis check that verifies that all implemented DBI methods contain ... in their formals. This excludes show() and all methods defined in this or other packages.
• Refactored bind_ tests to use the new parameter_pattern tweak (#95).
• Rough draft of transaction tests (#36).
• New fetch_zero_rows test, split from fetch_premature_close.
• The "compliance" test tests that the backend package exports exactly one subclass of each DBI virtual class.
• Document and enhance test for dbDataType("DBIDriver", "ANY") (#88).
• Minor corrections for "bind" tests.

Internal

• Isolate stress tests from main test suite (#92).
• Refactor test specification in smaller modules, isolated from actual test execution (#81). This breaks the documentation of the tests, which will be substituted by a DBI specification in prose.
• Align description of binding with code.
• Refactor tests for dbBind(), test is run by BindTester class, and behavior is specified by members and by instances of the new BindTesterExtra class.
• The skip argument to the test_() functions is again evaluated with perl = TRUE to support negative lookaheads (#33).
• Use dbSendStatement() and dbExecute() where appropriate.
• Avoid empty subsections in Rd documentation to satisfy R CMD check (#81).
