This package is primarily useful for developers of [DBI](https://dbi.r-dbi.org) backends.

It provides a considerable set of test cases for DBI backends.

These test cases correspond to the [DBI specification](https://dbi.r-dbi.org/articles/spec).

Please follow the steps below to add these test cases to your DBI backend.

## Installation

Install from CRAN via

```r

install.packages("DBItest")

```

or the development version using

```r

devtools::install_github("r-dbi/DBItest")

```

## Usage

In your driver package, add `DBItest` to the `Suggests:` and enable the tests.

Run the following code in you package's directory:

```r

# install.packages("usethis")

usethis::use_package("DBItest", "suggests")

usethis::use_test("DBItest")

```

This enables testing using `testthat` (if necessary) and creates, among others, a file `test-DBItest.R` in the `tests/testthat` directory.

Replace its entire contents by the following:

```r

DBItest::make_context(Kazam(), NULL)

DBItest::test_all()

```

This assumes that `Kazam()` returns an instance of your `DBIDriver` class.

Additional arguments to `dbConnect()` are specified as named list instead of the `NULL` argument to `make_context()`.

The `default_skip` argument to `make_context()` allows skipping tests that are not (yet) satisfied by your backend.
