Run all tests in specified file

Execute code in the specified file, displaying results using a reporter. Use this function when you want to run a single file's worth of tests. You are responsible for ensuring that the functions to test are available in the global environment.

test_file(path, reporter = default_reporter(), env = test_env(),
  start_end_reporter = TRUE, load_helpers = TRUE,
  encoding = "unknown", wrap = TRUE)

Arguments

path	Path to file.
reporter	Reporter to use to summarise output. Can be supplied as a string (e.g. "summary") or as an R6 object (e.g. SummaryReporter$new()). See Reporter for more details and a list of built-in reporters.
env	Environment in which to execute the tests. Expert use only.
start_end_reporter	Should the reporters start_reporter() and end_reporter() methods be called? For expert use only.
load_helpers	Source helper files before running the tests? See source_test_helpers() for more details.
encoding	Deprecated. All files now assumed to be UTF-8.
wrap	Automatically wrap all code within test_that()? This ensures that all expectations are reported, even if outside a test block.

Value

Invisibily, a list with one element for each test.

Details

Any errors that occur in code run outside of test_that() will generate a test failure and terminate execution of that test file.

Examples

path <- testthat_example("success")
test_file(path, reporter = "minimal")
#> .SW...

# test_file() invisibly returns a list, with one element for each test.
# This can be useful if you want to compute on your test results.
out <- test_file(path, reporter = "minimal")
#> .SW...
str(out[[1]])
#> List of 7
#>  $ file   : chr "test-success.R"
#>  $ context: NULL
#>  $ test   : chr "one plus one is two"
#>  $ user   : num 0.001
#>  $ system : num 0
#>  $ real   : num 0.001
#>  $ results:List of 1
#>   ..$ :List of 6
#>   .. ..$ message    : chr "1 + 1 not equal to 2.\nEqual"
#>   .. ..$ srcref     : 'srcref' int [1:8] 2 3 2 24 3 24 2 2
#>   .. .. ..- attr(*, "srcfile")=Classes 'srcfilecopy', 'srcfile' <environment: 0x562ecf2aac88>
