autotest_package: autotest_package

In autotest: Automatic Package Testing

autotest_package

Description

Automatically test an entire package by tracing calls made in its documented examples (and, for local source packages, its test suite) with typetracer, then testing each traced function call in turn.

Usage

autotest_package(
  package = ".",
  functions = NULL,
  exclude = NULL,
  test = FALSE,
  test_data = NULL,
  progress = c("bar", "tests", "none")
)

Arguments

package	Name of package, as either Path to local package source Name of installed package Full path to location of installed package if not on .libPaths, or Default which presumes current directory is within package to be tested.
functions	Optional character vector containing names of functions of nominated package to be included in 'autotesting'.
exclude	Optional character vector containing names of any functions of nominated package to be excluded from 'autotesting'.
test	If FALSE, return only descriptions of tests which would be run with test = TRUE, without actually running them.
test_data	Result returned from calling either autotest_types or autotest_package with test = FALSE that contains a list of all tests which would be conducted. These tests have an additional flag, test, which defaults to TRUE. Setting any tests to FALSE will avoid running them when test = TRUE.
progress	Style of progress display while testing functions, one of: "bar" (default) A cli progress bar. Automatically falls back to "none" when called from within a knitr document, to avoid literal ANSI escape sequences leaking into the rendered output. "tests" One line per function tested, showing ⁠[i / n]⁠. "none" No progress display at all.

Value

An autotest_package object which is derived from a tibble tbl_df object. This has one row for each test, and the following eight columns:

1. type The type of result, either "dummy" for test = FALSE, or one of "error", "warning", "diagnostic", or "message".

2. test_name Name of each test

3. fn_name Name of function being tested

4. parameter Name of parameter being tested

5. parameter_type Expected type of parameter as identified by autotest.

6. operation Description of the test

7. content For test = FALSE, the expected behaviour of the test; for test = TRUE, the observed discrepancy with that expected behaviour

8. test If FALSE (default), list all tests without implementing them, otherwise implement all tests.

Some columns may contain NA values, as explained in the Note.

Note

Some columns may contain NA values, including:

• parameer and parameter_type, for tests applied to entire functions, such as tests of return values.

• test_name for warnings or errors generated through "normal" function calls generated directly from example code, in which case type will be "warning" or "error", and content will contain the content of the corresponding message.
