gen_from_patch: Adds regression tests to specified package.

Description Usage Arguments

Description

Given a package, the code to be executed and a list of functions to capture, the function captures the selected functions from the package, then runs the specified code. It then generates tests from the captured information and using code coverage filters them against existing tests for the package. Those that increase the code coverage will be added to already existing testthat tests for the package.

gen_from_patch(package.dir = ".", code, functions, filter = TRUE,
  exclude_existing_tests = FALSE, build = TRUE, timed = FALSE, output,

Arguments

package.dir

Name/path to the package, uses devtools notation

code

Function (with no arguments) whose code will be executed and its calls in the package captured.

functions

Functions from the package to be captured, if missing, all package functions will be captured (character vector)

filter

T if the generated tests should be filtered

exclude_existing_tests

If TRUE, existing tests will be ignored from the code coverage

build

T if the package will be built beforehand

timed

TRUE if the tests result depends on time, in which case the current date & time will be appended to the output_dir.
