bq_test_project function

Project to use for testing bigrquery

You'll need to set the BIGQUERY_TEST_PROJECT (name of a project) and BIGQUERY_TEST_BUCKET (name of bucket) env vars in order to run bigrquery tests locally. I recommend creating a new project because the tests involve both reading and writing in BigQuery and Cloud Storage.

The BIGQUERY_TEST_PROJECT must have billing enabled for the project. While logged in, via bq_auth(), as a user with permission to work in BIGQUERY_TEST_PROJECT, run bq_test_init() once to perform some setup.

bq_test_project()

bq_test_init(name = "basedata")

bq_test_dataset(name = random_name(), location = "US")

bq_testable()

bq_authable()

gs_test_bucket()

gs_test_object(name = random_name())

Arguments

• name: Dataset name - used only for testing.

Returns

bq_test_project() returns the name of a project suitable for use in testing. bq_test_dataset() creates a temporary dataset whose lifetime is tied to the lifetime of the object that it returns.

Testing

In tests, bq_test_project() (and hence bq_test_dataset()) will automatically skip if auth and a test project are not available.

Examples

ds <- bq_test_dataset()
bq_mtcars <- bq_table_upload(bq_table(ds, "mtcars"), mtcars)

# dataset and table will be automatically deleted when ds is GC'd
