testthat 3.1.5

• Deprecation warnings are no longer captured by expect_warning(code, NA),
  expect_no_warning(code), or expect_silent(code). This ensures that they
  bubble up to the top level so that you can address them (#1680). If you want
  to assert that code does not throw a deprecation warning, use
  expect_no_condition(code(), class = "lifecycle_warning_deprecation").

• New experimental expect_no_error(), expect_no_warning(),
  expect_no_message(), and expect_no_condition() for asserting
  the code runs without an error, warning, message, or condition (#1679).

• Fixed a warning in R >=4.2.0 on Windows that occurred when using the C++
  testing infrastructure that testthat provides (#1672).

• Fixed an issue that could prevent compilation of Catch unit tests with
  LLVM 15. In the interim, packages needing a local workaround can set
  PKG_CPPFLAGS = -DCATCH_CONFIG_CPP11_NO_SHUFFLE in their src/Makevars.

• Improve way capture_output() handles encoding thanks to suggestion from
  Kurt Hornik (#1693). This means that snapshots using UTF-8 encoded text on
  windows work once again.

• local_reproducible_output() will no longer attempt to set the local language
  when LANG='C' is set or an R version is used that was not compiled with
  natural language support (NLS), which would previously emit non-test-related
  warnings during testing (@dgkf, #1662; @heavywatal, #1689).

• test_check() now suppresses hyperlinks since they'll take you to the wrong
  places (#1648).

• New set_max_fails() helper to make it easier to set the maximum number of
  failures before stopping the test suite. And the advice to set to Inf is
  now clickable (#1628).

• You can now configure the behaviour of the implicit
  devtools::load_all() call performed by devtools::test() in your
  package DESCRIPTION file (#1636). To disable exports of internal
  functions and of testthat helpers, use:

  Config/testthat/load-all: list(export_all = FALSE, helpers = FALSE)
  

  Helpers are now attached on the search path by default after calling
  devtools::test().
