  • return should be coercible to a blob via as.blob()
  • driver should accept values of blob class
  • dbDataType()

- Added tests for support of `blob` objects (input and output), but backends are not required to return `blob` objects (#98).

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.
